Simplify -4+ -3 + 6

Answers

Negatives cancel out positives so the +after the 4 changes to a minus and removes the - in the 3 so the equation changes to

-4 - 3 + 6 to make it easier, use the commutative property, 6 - 4 - 3 which equals -1

The scale factor of the blueprint of a garage door to the actual garage door is 0.05. the are of the actual garage door is 220 ft^2. What is the area of the garage door on the blueprint?

A. 0.55ft^2
B. 5.5ft^2
C. 11ft^2
D. 55ft^2

Answers

Answer:

option A

$0.55\ ft^(2)$

Step-by-step explanation:

Let

x-------> the area of the garage door on the blueprint

y------> the area of the actual garage door

z------> scale factor

we know that

The scale factor squared is equal to the area of the garage door on the blueprint divided by the area of the actual garage door

$z^(2)=(x)/(y)$

In this problem we have

$z=0.05, y=220\ ft^(2)$

substitute the values and solve for x

$0.05^(2)=(x)/(220)$

$x=220(0.05^(2))$

$x=0.55\ ft^(2)$

The scale factor 0.05 refers to length, so for area the scale factor is 0.05²=0.0025.

We then multiply: 220 ft²*0.0025=0.55 ft² (choice A)

8 - (2x - 9) = 17-24

Answers

Answer:

x=12

Step-by-step explanation:

8-(2x-+9)=17-24

8-2x=17-24-9

8-2x=-7+-9

8-2x=-16

-2x=-16-8

-2x=-24

x=-24/-2

x=12

8-(2x-9)=17-24
8 - 2x -+9 = -7
-2x+17=-7
-17 -17
-2x = -24
/-2. /-2

x = 12
