Solving an Equation
We are given the equation:
[tex]3(2x+5)=4(5-x)[/tex]The first step is to multiply the constants by the binomials in parentheses:
[tex]6x+15=20-4x[/tex]This step was correctly done by Jose.
The second step is to 'pass' the 4x from the right side of the equation to the left by adding 4x on both sides:
[tex]10x+15=20[/tex]This step was also correct.
Now we must 'pass' 15 to the right by subtracting 15:
[tex]10x=5[/tex]And here we find the first error. Jose subtracted 15-20 instead of 20-15 and erroneously got -5.
Answer: First error in step 3

Recall that two figures are similar if their corresponding angles have the same measure.
Therefore, if we reduce or increment the measurement of each angle, the resulting figure will not be similar to the original figure.
Now, notice that increasing the length of the sides of a polygon does not necessarily result in a similar figure, for example:
Now, recall that translations, rotations, reflections, and dilations result in similar figures.

Greta offers to buy a team photo for 15 of her teammates, but 6 of them don't want one. If a team photo costs $2, how much will Greta spend on her teammates? Choose the correct expression and solution to this problem. O A. The expression is 2(15 + 6). Greta will spend $42. OB. The expression is 2(15 - 6). Greta will spend $18. C. The expression is 15(6 - 2). PREVIOUS
The teammates are 15 but 6 of them do not want the photo, so the number of the teammates who wants the photo is 15 - 6.
Now, each photo cost $2 adn the number of photo is equal to the number of teammates who wants the photo which is (15-6), so the expression for the total cost is:
[tex]2\cdot(15-6)_{}[/tex]We have to multiply the cost of each photo for the number of photo Greta will buy.

Max knows that 1/2 stick of butter is enough for 2 batches of cookies how many cookies can he make with 4 sticks of butter
Answer:
16 batches of cookies
Step-by-step explanation:
First, I converted the fraction (1/2) to a decimal (.5). Then I divided 4 by .5 and got 8. Next, multiply 8 by 2 and we get 16, which means we can make 16 batches of cookies.
4 ÷ .5 = 8
8 × 2 = 16

cubic centimetres, then which of the following could be the length of the height in
centimetres?
(a) 1
(b) 5
(c) 25
(d)125
(e) 50
The length , width and height of a box with volume 125 cubic centimeters will be
1, 5 and 25.
Explanation:
The volume of a box can be calculated by multiplying its length, width, and height.
here given volume = 125
V = l x w x h
125 = l x w x h
l, w, h is the factors of 125
To find the common factors, we must first list the factors of each of the given numbers.
since 125 is composite number, it will have more than two factors.
125 → 1, 5, 25 and 125.
The factors of 125 is 1, 5, 25,125
here 125 cannot consider as length since volume is 125 other sides cannot be 0.
so the length, width, height can be 1 , 5, 25.

The order of the numbers from lowest to highest is 4.68 × 10⁻⁶, 8.34 × 10⁻², 1.2 × 10⁷, 3.24 × 10⁹ and 5.48 × 10⁹
What is the order of the numbers from lowest to highest?The given numbers are expressed in standard form. Standard form is a way of writing numbers as a power 10 e.g 100 = 1 × 10² and 0.01 = 1 × 10⁻².
So converting the numbers back to ordinary numbers will be useful.
To do this, we will multiply or divide the powers of 10 with the decimal numbers.
We will multiply if the power is positive e.g 2.4 x 10² = 2.4 x 100 = 240 and divide if the power is negative 2.4 x 10⁻² = 2.4/100 = 0.024
3.24 × 10⁹ = 3.24 x 1000,000,000 = 3240000000
4.68 × 10⁻⁶ = 4.68 / 1000000 = 0.00000468
5.48 × 10⁹ = 5480000000
8.34 × 10⁻² = 8.34/100 = 0.0834
1.2 × 10⁷ = 12000000
Therefore, arranging from lowest to highest. We have:
4.68 × 10⁻⁶, 8.34 × 10⁻², 1.2 × 10⁷, 3.24 × 10⁹ and 5.48 × 10⁹

A linear equation has a constant slope.
For every step increase in x, there needs to be another step increase in y.
From the table,
x decreases by 2 units
y doesn't decrease by the same unit
So, this cannot be linear relationship.
To see whether it is quadratic or exponential, we graph the (x,y) points and see the general shape of the curve by connecting the points in a smooth curve.

2. I have two turtles. Today, the older turtle's age is 11 times that of the younger turtle. In 24 years, the older turtle's age will only be 7 times that of the younger turtle. If both turtles survive until then, how many years from today will the older turtle's age be 3 times that of the younger turtle?
1) A number that is divided by 5, with the result as 50 less than if the number had been divided by 6 is; -1500
2) If both turtles survive until then, the number of years from today that the older turtle's age would be 3 times that of the younger turtle is; 146 years
How to solve Algebra Word Problems?1) Let the number be x. We are told that it is divided by 5, and the result is 50 less than if the number had been divided by 6. Thus, we have;
(x/6) - (x/5) = 50
Multiply through by 30 to get;
5x - 6x = 1500
-x = 1500
x = -1500
2) Let the older turtle be x and the younger one be y.
Today, the older turtle's age is 11 times that of the younger turtle. Thus;
Todays age;
Older turtle = 11y years
Younger turtle = y years
In 24 years, the older turtle's age will only be 7 times that of the younger turtle. Thus;
11y + 24 = 7(y + 24)
11y + 24 = 7y + 168
11y - 7y = 168 - 24
4y = 144
y = 144/4
y = 36
Thus;
Age of older turtle today = 11 * 36 = 396 years
Age of younger turtle today = 36 years
Thus, for older turtle to be thrice the age of younger turtle, then;
3(36 + t) = 396 + t
108 + 3t = 396 + t
2t = 292
t = 292/2
t = 146 years

1. -35=5b2. x-6=-263. 130=13b4. 19=16+m5. a+15=116. p-8= -87. -17+x= -248. 4+n=139. -3x=010. 0.6=m-0.811. x-5.3=1.27
In any equation in math, the most basic thing is the the fact that both expressions on either side of the equality sign are of the same value. This means -35 and 5b (in number 1) are of the same value. Therefore, whatever you do to the one on the left, you must likewise do to the one on the right. That is, if you have to add 10 to the one on the left, you must simultaneously add 10 to the one on the right. Hence, number 1 is solved as follows;
(1) -35 = 5b
To eliminate the 5 and isolate the b variable, divide both sides by 5
-35/5 = 5b/5
- 7 = b
(2) x - 6 = - 26
Add 6 to both sides of the equation;
x - 6 + 6 = - 26 + 6
x = - 20
(3) 130 = 13b
Divide both sides of the equation by 13
130/13 = 13b/13
10 = b
(4) 19 = 16 + m
Subtract 16 from both sides of the equation
19 - 16 = 16 - 16 + m
3 = m
(5) a + 15 = 11
Subtract 15 from both sides of the equation
a + 15 - 15 = 11 - 15
a = - 4
(6) p - 8 = - 8
Add 8 to both sides of the equation
p - 8 + 8 = - 8 + 8
p = 0
(7) - 17 + x = - 24
Add 17 to both sides of the equation
- 17 + 17 + x = - 24 + 17
x = - 7
(8) 4 + n = 13
Subtract 4 from both sides of the equation
4 - 4 + n = 13 - 4
n = 9
(9) - 3x = 0
Divide both sides of the equation by - 3
- 3x/-3 = 0/-3
x = 0
(10) 0.6 = m - 0.8
Add 0.8 to both sides of the equation
0.6 + 0.8 = m - 0.8 + 0.8
1.4 = m
(11) x - 5.3 = 1.27
Add 5.3 to both sides of the equation
x - 5.3 + 5.3 = 1.27 + 5.3
x = 6.57

8/9 - 1/3
To subtract these two fractions, first find a common denominator.
The common denominator will be the
least common multiple for the two denominators.
In this case, the least common multiple of 9 and 3 is 9.
So to subtract, a denominator of 9 is needed in each fraction.
8/9 already has 9 in the denominator so it stays the same.
To get a 9 in the denominator of 1/3, multiply top and bottom by 3.
This gives us 3/9.
So we have 8/9 - 3/9 which is 5/9.

Marcus has twice as many CD's as Kristen. Sherry has 12 more than Kristen. Together they have 100 CD's. How many does each person have?
Marcus have 44 CDs, Sherry have 34 CDs and Kristen have 22 CDs.
Let us assume that Kristen has x numbers of CD's.
According to the provided situation,
Marcus have twice the number of CDs as Kristen.
Number of CDs of Marcus = 2x
The number of CDs of Sherry is 12 more than the CDs of Kristen
Number of CDs of of Sherry = 12 + x
Total number of CDs combined are 100.
So, we can write,
x + 2x + (12 + x) = 100
4x + 12 = 100
Any equation with the highest degree of variable as one, just like the above equation is called Linear Equation.
Further solving the Equation,
4x + 12 = 100
4x = 88
x = 22
The number of CDs that Kristen has is 22.
The number of CDs that Marcus have is 2(22).
The number of CDs Marcus gas is 44.
The number of CDs Sherry has is (12 + x) which is equal to 34.
The number of CDs Kristen, Marcus and Sherry have is 22, 44 and 34 respectively.
