PLEASE HELP ME PLEASE

suter [353]

Answer:

$1.21

Step-by-step explanation:

Start by finding the total amount spent on shirts. Do this by multiplying $3.65 and 4 together. You will get 14.6. So, he spent $14.60 on 4 shirts. Take this amount and subtract it from the total amount paid for shirts and socks. $23.07 minus $14.60. This will give you $8.47 left to spent on socks. $8.47 divided by 7 is $1.21. Therfore, James paid $1.21 per pair of socks.

Please find the measure of the exterior angle

makvit [3.9K]

Answer:

exterior angles:

144°and 36°

126° and 54°

90° and 90°

Step-by-step explanation:

we know that each angle in a triangle adds up to 180°.

so,

2x+3x+5x=180

10x=180

x=180/10

x=18

the interior angles are:

2x=36°

3x=54°

5x=90°

and explanation is provided to find the exterior angles above.(sorry for the bad handwriting)

HELP PLEASE EQUATION OF PARABOLA

Masteriza [31]

It has a minimum value at x = 3 and f(x) = 4

Vertex form is

f(x) = a(x - 3)^2 + 4 where a is some constant to be found

From the graph when x = 5 f(x) = 15, so

15 = a * 2^2 + 4

a = 15-4/4 = 11/4

so our equation is f(x) = 11/4(x - 3)^2 + 4

The drama club spent $35 on decorations and $8.50 per person on food for a cast party. The total cost of the food

jenyasd209 [6]

Answer:

Option C) 27 people

Step-by-step explanation:

Let

x ----> the number of people

we know that

The cost of decorations ($35) plus the number of people (x) multiplied by the cost per person on food ($8.50) must be equal to $264.50

so

The linear equation that represent this situation is

$35+8.50x=264.50$

solve for x

Subtract 35 both sides

$8.50x=264.50-35$

$8.50x=229.50$

Divide by 8.50 both sides

$x=229.50/8.50$

$x=27\ people$

Solve the following equation for x.

Vaselesa [24]

Solve for x (isolate/get x by itself)

$\frac{1}{4}x-7=\frac{3}{8}x-5$ Add 5 on both sides

$\frac{1}{4}x-7+5=\frac{3}{8}x-5+5$

$\frac{1}{4}x-2=\frac{3}{8}x$ Subtract 1/4x on both sides

$\frac{1}{4}x-\frac{1}{4}x-2=\frac{3}{8}x-\frac{1}{4}x$

$-2=\frac{3}{8}x-\frac{1}{4}x$ Make the denominators the same of the fractions in order to combine them. Multiply 2 to the top and bottom of 1/4x

$-2=\frac{3}{8}x-\frac{2}{8}x$

$-2=\frac{1}{8}x$ Multiply 8 on both sides

$-2(8)=(8)\frac{1}{8}x$

-16 = x
