Question

Hmmmmmm,can anyone solve this ?

Answer 1

Answer:

Square=5

Triangle=17

Circle=8

Step-by-step explanation:

s=square, c=circle, t=triangle

What each column tells us:

2t+2c=50

3s+t=32

c+2s+t=35

What each row tells us:

2t+c=42

c+2s=18

t+2s=27

c+s+t=30

Solve for s and t:

We will use 3s+t=32 and t+2s=27 to find s and t.

3s+t=32

t=32-3s

Plug in 32-3s for t and solve for s.

(32-3s)+2s=27

32-s=27

-s=27-32

s=5

Square=5

Plug in 5 for s and solve for t.

t+2(5)=27

t+10=27

t=17

Triangle=17

Use c+s+t=30 to find c:

Plug in 5 for s and 17 for t.

c+5+17=30

c+22=30

c=8

Circle=8
