Step-by-step explanation:

well, the arcs WS and ST together are the full half-circle and therefore 180°.

that means

5x + 37 + 3x - 9 = 180

8x + 28 = 180

8x = 152

x = 19

frutty [35]

Answer:

Step-by-step explanation:

80:24

100:n

80(n)=100×24

A little equation and after it's solve the variable (n) will be equal to 30

If you have fifty-four pieces of candy that need to be split up evenly
Sergeeva-Olga [200]

All we need to do is divide.

54 / 6 = 9

Therefore, each person gets 9 pieces of candy.

Best of Luck!

Two cans of paint and 1 brush cost $37. Four cans of paint and 3 brushes cost $81. Find the cost of one can of paint.
weeeeeb [17]
2c + b = 37 ....multiply by -3
4c + 3b = 81
------------------
-6c - 3b = - 111 (result of multiplying by -3)
4c + 3b = 81
------------------add
-2c = - 30
c = -30/-2
c = 15 <== $ 15 for a can of paint

and it costs $ 7 for each brush
