3(x + 2) = 2x + 5 justification/ reason
Answer:
x = -1
Step-by-step explanation:
3(x + 2) = 2x + 5
Use the distributive property on the left side.
3x + 6 = 2x + 5
Subtract 2x from both sides. Subtraction property of equality.
x + 6 = 5
Subtract 6 from both sides. Subtraction property of equality.

Xavier borrowed $1950 from his parents. Each month he repaid his parents $325. The table shows the function relating Javiers remaining balance to the numbers of months.
The loan repayment is an illustration of a linear function.
He will finish paying the loan after 6 months.
A linear function is illustrated as: [tex]\mathbf{y = mx + b}[/tex]
In this case:
y represents, the amount left after each the monthly repaymentx represents the number of monthsb represents the loan amount i.e. 1950m represents the monthly payment i.e. 325.Because the amount reduces after each monthly payment, the value of m will be taken as: m = -325
So, we have:
[tex]\mathbf{y = -325x +1950}[/tex]
When he finishes paying the loan, we have: y = 0.
So, the equation becomes
[tex]\mathbf{0 = -325x +1950}[/tex]
Add 325x to both sides
[tex]\mathbf{325x =1950}[/tex]
Divide both sides by 325
[tex]\mathbf{x =6}[/tex]
Hence, he will finish paying the loan after 6 months.

a) Solution for x:
x = {x / -3 ≤ x ≥ 2; x≠-2;1)
Interval notation:
(-∞, -3] ∪ (-2, 1) ∪ [2, +∞)
Step-by-step explanation:
Rational Inequality is inequality with rational numbers or expressions.
The symbols in inequality are:
Less than (<)
Greater than (>)
Less than or equal to (≤)
Greater than or equal to (≥)
In fraction or rational expression, the denominator is not 0. A zero-denominator renders the expression undefined.
Given:
(x+3)(x-2)/(x+2)(x-1)≥0
The rational expression:
Numerator: (x+3)(x-2)
Denominator: (x+2)(x-1) where x ≠ -2 and x ≠ 1 because the values -2 or +1 will make the expression undefined
Find the solution for x by equation the factors in enumerator to 0:
x+3 ≥ 0
x ≥ -3
x ≤ -3
x - 2 ≥ 0
x ≥ 2
But:
x ≠ -2
x ≠ 1
Hence:
Solution for x:
x = {x / -3 ≤ x ≥ 2; x≠-2;1)

In February, you have a balance of $270 in your bank account. Each month you deposit $45. Let January = 1, February = 2, and so on. Write an equation for this situation. Use the equation to find the balance in June.
A. y = 45(x – 4); $180
B. y – 270 = 45(x – 2) ; $450
C. y = 45(x – 4); $270
D. y – 270 = 45x; $45
Answer:
B. y – 270 = 45(x – 2) ; $450
Step-by-step explanation:
In February, you have a balance of $270 in your bank account.
In January, you have a balance of $270 - $45 = $225 in your bank account.
In December, you have a balance of $225 - $45 = $180 in your bank account.
y = $180 + $45x, where x = 1, 2, 3, 4...
Balance in June: x = 6
y = $180 + $45x = $180 + $45×6 = $180 + $270 = $450
The complete question is:
In February, you have a balance of $270 in your bank account. Each month you deposit $45. Let January = 1, February = 2, and so on. Write an equation for this situation. Use the equation to find the balance in June.
Answer:
$450 in June
Step-by-step explanation:
$X = 270 + 45 × ( number of month)
In this problem, February, the month you start with, would be month 0.
June would be 4.
$X = 270 + 45 × 4
= 270 + 180
= $450 in June
$450 in June.

Daisy’s flower shop sold 135,649 flowers during its first year. The second year, the shop sold additional 9,754 flowers. How many flowers did the shop sell in these two years?
Answer:
281052
Step-by-step explanation:
To solve for the second year we add 135,649 and 9754, because there is an additional amount of flowers. Then we add the flowers from the first year to get the total amount of 281052.

work out 5^-2 x cube root 8
Answer:
0.08
Step-by-step explanation:
5 ^-2 * cube root of 8
first of all, let us solve 5^-2
using the law of indices;
a^-2 = 1 / a ^2
following this law, we have;
5^-2 = 1 / 5^2
we know that 5^2 = 25
therefore,
5^-2 = 1 / 25
now, let is continue by solving the cube root of 8
now, there are three ways of solving this;
we could just simply think of any number that when multiplies itself three times times, it gives 8, or we could just simply use a calculator
regardless of what we use, we have to end up with the number 2 as the answer
leading is to our conclusion.
from all our solution, we have reduced our question to;
1 / 25 ( which is 5^-2) * 2 ( which is the cube root of 8 )
= 1 / 25 * 2 / 1
note that 2 is the same as 2 / 1. We put it like this when we want to carry out an operation on an integer ( e.g. 2) and and a fraction ( e.g. 1 / 25 )
so,
1 / 25 * 2 / 1 =
2 / 25 ( the two multiplies the 1 in 1 / 25 and the 25 multiplies the 1 in 2 / 1)
leaving our answer in decimal, we have;
0.08

Maria can read 10 pages of a book in 25 minutes. How many pages can she read in 120 minutes?
Answer:
48
Step-by-step explanation:

I got 4.8 by doing this:
I already knew that 25×5 would equal 125.
but since they wanted 120, I instead multiplied 25 by 4 with decimals from 1-10 until I got 120, then I multiplied that with the 10 pages to get my answer.

Person A is 49 times older than person B. the sum of their ages 1.450
Answer:
Step-by-step explanation:
Is 1.450 correct? 145 would make more sense. I'd even go with 1,450, just for a laugh. I'll assume 1.450 is the correct number here. I'll assume assute the question eventually asks how old are A and B.
A = 49(B)
A+B=1.450
Substitute:
49B+B=1.450
50B = 1.450
B = 0.029
A = 49(B)
A = 49*(0.029)
A = 1.421

Solve for the indicated variable. Include all of your work in your answer. Submit your solution.
Answer:
Step-by-step explanation:
first you would want to flip the equation then multiply 9 on both sides to get
5(F-32)=9C
Then you would want to divide both sides by 5 which crosses out the 5 from the equation and is moved to the other side which then were you simplify getting
F-32=9C/5
Lastly you want to add 32 to both sides causing - 32 to cross out getting
F=9C/5 +32
making F=9C/5 + 32 our answer
