Answer:
x = -5.25 or 21/4
Step-by-step explanation:
When break the bracket out, if there is a minus sign in front of the bracket, when we break it out, the sign inside the bracket would become positive:
67 = 18 - (8x - 7)
67 = 18 - 8x - (-7)
67 = 18 - 8x + 7
67 = 18 + 7 - 8x
67 = 25 - 8x or rewrite for easier look: 25 - 8x = 67
25 - 8x = 67
8x = 25 - 67
8x = -42
Divide both side by 8, we got:
x = -42 / 8
x = -5.25 or 21/4
Hope this helped :3
46 - 4 = 3b + 3
Simplify the left side:
42 = 3b + 3
Subtract 3 from both sides:
39 = 3b
Divide both sides by 3:
b = 13
Answer:
A) 440.44 units³
B) similar figures
C) 1486.485 units³
Step-by-step explanation:
Volume = ⅓× base area × height
= ⅓ × 110.11 × 12 = 440.44 units³
B) he doesn't have to make calculations again because the two pyramids are similar.
If the ratio of sides is given, he can find the other volume using:
(side1/side2)³ = volume1/volume2
(2/3)³ = 440.44/volume2
Volume2 = 440.44 × 27/8
Volume2 = 1486.485 units³
