A + c = 158......a = 158 - c
9.90a + 5.50c = 1265
9.90(158 - c) + 5.50c = 1265
1564.20 - 9.90c + 5.50c = 1265
- 4.40c = 1265 - 1564.20
-4.40c = - 299.20
c = -299.20/-4.40
c = 68 <=== 68 child tickets sold
Answer:
C
Step-by-step explanation:
ZC is an altitude, thus ∠ZCY = 90°
The sum of the3 angles in a triangle = 180°
Sum the 3 angles in ΔCYZ and equate to 180
90 + 5x + 22 + 12x = 180 ← simplify left side
17x + 112 = 180 ( subtract f112 from both sides )
17x = 68 ( divide both sides by 17)
x = 4
Hence
∠WZC = 12x = 12 × 4 = 48° → C
3.5 divided by 4.
Each sister will receive 0.875 feet of ribbon.
The equation for Zimbabwe's growth would be:
4x+1=12.6
Solve for x.
4x+1=12.6
Subtract 1 from both sides.
(4x+1)-1=(12.6)-1
4x=11.6
Divide both sides by 4.
(4x)/4=(11.6)/4
x=2.9
The approximate population of Zimbabwe in 1950 was 2.9 million.
