Answer:

Graph A

Step-by-step explanation:

Let

x-------> the number of cereal boxes

y------> the number of cartons of milk

we know that

x+y=5 -----> equation A

y=2+2x -----> equation B

Solve the system of equations

Substitute equation B in equation A

x+(2+2x)=5

3x=5-2

3x=3

x=1

Find the value of y

y=2+2x------ y=2+2(1)=4

The solution of the system is the point (1,4)

therefore

The answer is the graph A

Answer:

153/20

Step-by-step explanation:

I assume you're asking

2 \frac{1}{4}  \times 3 \frac{2}{5}

So

\frac{9}{4}  \times  \frac{17}{5}

=

\frac{153}{20}

Find the value of z in the similar figures (round to the nearest tenth)
MrRa [10]
As they are similar figures,we can use the ratio of the side to find out the value of z.

The only side that both have the value indicated is 4 and 6,therefore we would use it to find the ratio.

The eqaution would be:
6/4 = z/8
3/2 = z/8
3×8 = 2z
z = 24/2
z = 12

Thus the value of z is 12.

Hope it helps!
