Answer:

Step-by-step explanation: L=W+3

2(W+3)+2W=24

2W+6+2W=24

4W=24-6

4W=18

W=18/4

W=4.5 ANSWER FOR THE WIDTH.

L=4.5+3

L=7.5 ANSWER FOR THE LENGTH.

PROOF

2*4.5=2*7.5=24

9+15=24

24=24

Graph the equation to solve the system. y=2x+7 1/2y=x+7/2
vlabodo [156]

Given equation is y=2x+7 and \frac{1}{2}y=x+\frac{7}{2}

Let's simplify the 2nd equation \frac{1}{2}y=x+\frac{7}{2} before we can start graph so that calculation will be easy

\frac{1}{2}y=x+\frac{7}{2}

multiply both sides by 2 to cancel out fractions

2*\frac{1}{2}y=2*x+2*\frac{7}{2}

y=2x+7

which is exactly same as the first equatoin so graph of both will be exactly same and solution will be infinitely many solutions.

y=2x+7 has y-intercept 7 so first point will be (0,7). Slope is 2 so rise 2 unit up then 1 right and graph the new point.

Y varies directly as X. If X=2 and y=10. Find Y when X=7
ser-zykov [4K]

Answer:

y= 35

Step-by-step explanation:

y directly proportional to x

where x= 2, y= 10

y=kx

10= k× 2

k= 10/2

k= 5

to find y when x is 7

y = kx

y = 5× 7

y= 35

---------------

75 peanuts


5 bags           8 bags

---------------  = ------------------

75 peanuts      x peanuts

Using cross products

5x = 75*8

5x = 600

Divide each side by 5

5x/5 = 600/5

x = 120
