------ = ------------

3+9           12

3           x

------ = ------------

Answer: x = 3

Step-by-step explanation:

The question involves two triangles,

Big triangle AED,

small triangle ABC.

Both triangles are similar and

AED has base of 9 + 3 = 12 and heught of 12

ABC has base of 3 and height of x

To find x we equate the ratios of their height to their base

x/3 = 12/12

x/3 = 1

x = 3

A salesperson makes a commission of 1% of all cars that he sells. If his goal is to make at least $4,285 worth of commission dur
shusha [124]

Answer: $428,500

Step-by-step explanation:

Since commission is 1% = 1/100

Let the missing amount be represented as p

From the question, 1/100 × p = 4285

1/100p = 4285

Divide both sides by 1/100 to get the value of p

p = $4285 ÷ 1/100

p= $4285 × 100/1

p = $428500; i hope this helps, please mark as brainliest answer.

Veseljchak [2.6K]
For lines to be perpendicular they would need to have opposite slopes, so for a slope of -3/7 the slope of a perpendicular line would be 7/3
