<h3>Answer: 104 miles</h3>

=========================================================

Explanation:

  • x = number of miles Amy drove
  • 2x = number of miles Jessica drove, since she drove twice the distance as Amy did

Combine the two expressions: x+2x = 3x

The two girls traveled a total distance of 312 miles, so 3x = 312

Divide both sides by 3 to solve for x. You should get x = 104

Amy drove 104 miles and Jessica drove 2*104 = 208 miles

Check:

Amy + Jessica = 104 + 208 = 312

The answer is confirmed.

Answer:

Amy drove 104 miles

Step-by-step explanation:

let 'a' = miles Amy drove

let '2a' = miles Jessica drove

a + 2a = 312

3a = 312

a = 312/3

a = 104

2a = 208

Check:  104+208 should equal 312 and it does

I honestly don't even know where to start //// on his last 4 tests , Danilo scored 55% 78% 84% and 93%. What score should he get
skelet666 [1.2K]

Answer:

The answer to your question is He must get 80%

Step-by-step explanation:

Data

Scores 55%, 78%, 84%, 93% and X

Average 80%

Process

1.- Write a equation to solve this problem

- There are five scores

Score 1 = S1 = 55

Score 2 = S2 =  78

Score 3 = S3 = 84

Score 4 = S4 = 93

Score 5 = S5 = X

Equation

               Average = (S1 + S2 + S3 + S4 + S5) / 5

- Solve for S5

               5 Average = S1 + S2 + S3 + S4 + S5

               S5 = 5 Average - S1 - S2 - S3 - S4

- Substitution

               S5 = 5(80) - 55 - 78 - 84 - 93

- Simplification

               S5 = 400 - 310

- Result

               S5 = 90
