Evaluate the following expression when b = -4 , -4.5b=

Mathematics
1 answer:
Elza [17]3 years ago
6 0

Answer:

18

Step-by-step explanation:

The question is asking you to evaluate -4.5b, which is a simplified way of saying

-4.5 * b

Since we know that b = -4, we can insert that instead of b.

-4.5 * -4

The two negatives cancel each other out, so you're left with

4.5 * 4 = 18

What is the surface area to volume ratio of a 5 cm cube?
joja [24]
Answer: 6/5

Explanation:
Given: 5cm cube
This means each side is 5 cm because a cube has equal sides.

Area of a square is length times width so area of 1 side of a cube:
= 5 x 5
= 25

Surface area is the area of one side of a cube times the number of sides. Now, how many sides does a cube have? 6
= 25 x 6
= 150

Surface area of a 5cm cube = 150

Volume is length times width times height:
= 5 x 5 x 5
= 125

Ratio of surface area to volume:
= 150/125
= 6/5

Which of these points lies on the line described by the equation below? y+8=-4(x+7)
timama [110]
D. (-8,-7) Simplifying<span>y + -8 = 4(x + 7) Reorder the terms: -8 + y = 4(x + 7) Reorder the terms: -8 + y = 4(7 + x) -8 + y = (7 * 4 + x * 4) -8 + y = (28 + 4x) Solving -8 + y = 28 + 4x Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '8' to each side of the equation. -8 + 8 + y = 28 + 8 + 4x</span>
