Yousef saves $25 each month for a year. One year is 12 months. How much money does he save in one year?

Given:

The statement is "the difference of 18 and 12".

To find:

The expression for the given statement.

Solution:

We have,

Given statement = The difference of 18 and 12.

We use subtraction, to find the different between two numbers and subtraction is represented by negative sign. So, we need to subtract second number form the first number.

The difference of 18 and 12 = 18 - 12

Therefore, the required expression for the given statement is 18-12.

Answer:

[tex] - 4(7 - 2m) + 11m \\ = - 28 + 8m + 11m \\ = \boxed{19m - 28}[/tex]

Expression (19m-28) is equivalent to -4(7 - 2m) + 11m.

Answer:

Below

Step-by-step explanation:

1. Linear because it is of the form y = mx + b. The variable x  is of the first degree.

The coefficient of x (1/3)  ( = slope) is positive so it is increasing.

2. This is non-linear because the variable x is an exponent.

3. Because  its of the second degree (x^2) - it is non-linear.

Answer:

5 inches

Step-by-step explanation:

"perimeter of 32"

a+b+c = 32

a ≤ b ≤ c

"medium side is 7 more than the short side"

b = a+7

"longest side is 3 times the length of the shortest side

c = 3a

Substitution

a + (a+7) + (3a) = 32

5a = 25

a = 5 inches

Answer: The length = [tex]5\dfrac12[/tex] units

Step-by-step explanation:

Given: Area of carpet = [tex]4\dfarc18 \text{ sq. units}=\dfrac{33}{8}\text{ sq. units}[/tex]

Width of carpet = [tex]\dfrac34[/tex] units

Shape of carpet = Rectangle

Area of rectangle = length x width

So,

length = [tex]\dfrac{Area}{width}[/tex]

[tex]=\dfrac{\dfrac{33}{8}}{\dfrac34}\\\\=\dfrac{33}{8}\times\dfrac43\\\\=\dfrac{11}{2}\\\\=5\dfrac12\text{ units}[/tex]

Hence, the length = [tex]5\dfrac12[/tex] units

Answer:

X=45

Step-by-step explanation:

You see the congruency markings use B.A.T to determine that the unmarked angle is x, therefore 4x=180 and x=45

Answer:

40% number of calories have increased

Step-by-step explanation:

Old Value ( Calories consume before)  = 2000

New Value (increase in Calories consumed) = 2800

We need to find by what percent did the number of calories increase ​

To find percent increase, the formula used is:

[tex]Percent\: increase=\frac{New\:Value-Old\:Value}{Old\:Value}\times 100%[/tex]

Putting values in formula and finding percent increase

[tex]Percent\: increase=\frac{New\:Value-Old\:Value}{Old\:Value}\times 100\%\:\\Percent\: increase=\frac{2800-2000}{2000}\times 100\%\: \\Percent\: increase=\frac{800}{2000}\times 100\%\: \\Percent\: increase=0.4\times 100\%\: \\Percent\: increase=40\%[/tex]

So, 40% number of calories have increased

Answer:

  -5/4 +i(√2)/4 and -5/4 -i(√2)/4

Step-by-step explanation:

I find simplest form to be easier to get to if the leading coefficient is 1. Dividing by 16, we have ...

  x^2 +5/2x +27/16 = 0

Completing the square by adding and subtracting the square of half the x-coefficient, we get ...

  (x^2 +5/2x +25/16) +27/16 -25/16 = 0

  (x +5/4)^2 = 2/16

Subtracting 2/16, taking the square root, and subtracting 5/4 gives ...

  x +5/4 = ±√(-2/16)

  x = -5/4 ±i(√2)/4

The roots are -5/4 +i(√2)/4 and -5/4 -i(√2)/4.

Answer:

a) Constant of proportionality = 0.25

b) The constant of proportionality provides the cost of one apple.

c) n = 12

Step-by-step explanation:

It is given that:

c = 0.25n

a) Here,

c = cost of apples

n = number of apples

As the proportion varies directly.

c ∝ n

c = kn

Comparing the equations

k = 0.25

b) The constant of proportionality provides the cost of one apple.

c) Putting c = $3

3 = 0.25n

Dividing both sides by 0.25

n = 12

Thus,

a) Constant of proportionality = 0.25

b) The constant of proportionality provides the cost of one apple.

c) n = 12

Answer:

The shortest side is 26 units.

Step-by-step explanation:

(2×13)+(6×13)+(7×13) = 195

2×13 = 26

what is this

Step-by-step explanation:

Option #1 – charges 5% simple interest per year; this is a short-term loan for only 5-years.

Option #2 – charges 7% simple interest per year; this is a short-term loan for only 3-years.

Option #3 – charges 3.2% simple interest per year; there is no time limit on this loan (as a group determine how long you think it will take you to make enough money to be able to pay back the loan with interest)

Option #4 - charges 10% simple interest per year; only lasts 10 months

Option what is this

Answer:

Its option one

Answer:

15:x or 15 to x

Step-by-step explanation:

it depends on what the question is asking, so if they want you to fill in a number, you could replace x with any number you'd like. but its probably a word problem they want you to put as numbers, so bc you dont know what 'a number' is, you can pick a variable such as x to replace it with.

hope this helps :)

Answer:

Equation: 5x+5 = 30

x = 5

Step-by-step explanation:

Since vertically opposite angles are equal, then;

5x+5 = 30

Subtract 5 from both sides

5x +5-5 = 30-5

5x = 25

x = 25/5

x = 5

The required equation is 5x+5 = 30 (vertically opposite angles are equal)

The value of x is 5

Answer:

y = x - 3

Step-by-step explanation:

First you want to combine like terms (so get x on one side and y on the other).

2y = 5y + 9 - 3x

-3y = -3x + 9

Then just solve for y by dividing by -3

y = (-3x + 9)/-3

y = x - 3
