Answer: option C. (5,7)

Step-by-step explanation:

first, in order to find X, simply divide that equation by 3 in order to get X by itself.

3x/3 = 15/3

x = 5

then, i just substituted the value of X, 5, into the equation on the top. this is how we find Y.

6(5) - 2y = 16

30 - 2y = 16

at this point, we divide by 2 in order to get Y by itself.

30/2 - 2y/2 = 16/2

15 - y = 8

then, we subtract 15 from both sides of the equation so that the variable, Y, is by itself completely.

-y = -7

finally, since both are negatives, we can cancel out the negative sign and ake the whole equation positive.

x = 5, y = 7

so, in conclusion, the answer is C. (5,7)

The sum of 3 times the value of x and 2 is equal to 4 less than 5 times the value x. Which equation can be used to find the valu

Komok [63]

Answer:

Write the written problem into an equation to get:

3x +2 = 5x -4

To solve:

Add 4 to each side:

3x+6 = 5x

Subtract 3x from each side:

2x = 6

Divide both sides by 2:

x = 6/2

x = 3

The nutrition facts label on a container of dry roasted cashews indicates there are 161 calories in 28 grams. You eat 9 cashews

RoseWind [281]

Answer:

there are 161 calories in 28 gram,then:

one gram of dry roasted cashews contains=161/28=5.75 calories

You eat 12 gram of it, =12*5.75=69 calories

9 cashews has 12gram, then:

one gram of dry roasted cashews contains= 9/12 = 0.75 cashews

there are total of 28gram in one serving.

Therefore cashews in one serving = 0.75*28=21cashews

a)69 calories

b)21cashews

A man has a 10m X 10m square garden. In the center is a 2m X 2m square patch which he cannot use. He divides his usable space in

ra1l [238]

Answer:

4m X 6m

Step-by-step explanation:

This is because if there is a 2m square in the middle, there is 8 m of usable space left along both sides of the garden.

Because the 2m square was in the middle, there is 8/2 = 4m along each width of the 4 small rectangles.

Becuase 4m is the width, there is 10 - 4 = 6m along each rectangle's length.

Really never learned this

kykrilka [37]

The perimeter of a two-dimensional figure is always the sum of its sides.

The exercise mat has a perimeter (P) of 36 feet. ...

Let length be L, and width be W.

P = 36

L = 2w

P=2(l+w)=2·(12+6)=36

L = 12 feet

W = 6 feet

Find the measure of angle y. Round your answer to the nearest hundredth. (please type the numerical answer only)

Eduardwww [97]

Given:

The figure of a right triangle. $PO=12,m\angle O=y^\circ$ and perpendicular = 12.

To find:

The measure of angle y.

Solution:

In a right angle triangle,

$\sin\theta=\dfrac{Perpendicular}{Hypotenuse}$

In the given right angle triangle,

$\sin y^\circ=\dfrac{7}{12}$

$y^\circ=\sin ^{-1}\dfrac{7}{12}$

$y^\circ=35.685335^\circ$

$y^\circ\approx 35.69^\circ$

Therefore, the measure of angle y is $y^\circ =35.69^\circ$ .
