Answer:
14 problems worth 5 points and 15 problems worth 2 points
14 x 5 = 70
15 x 2= 30
70 + 30= 100
14+15 = 29 5 x 14 + 2 x 15=100
Answer:
z=2
Step-by-step explanation:
56-35z+17=3
73-35z=3
-35z=-70
z=2
Answer:
x = 16
Step-by-step explanation:
Use that the addition of all internal angles of a triangle must add up to 180, and the fact that the two given triangles are similar:
51 + 65 + 4 x = 180
combine and solve for "x"
116 + 4 x = 180
4 x = 180 - 116
4 x = 64
x = 64 / 4
x = 16
The answer is 72 because 4x18=72,6x12=72 and 8x9=72
The answer is 9,000 because there are 10,000 milliliters in 10 liters so 1,000- 10,000 is 9,000 hope that helps :)
