<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

Answer:

  • golf: $10
  • batting: $2.50

Step-by-step explanation:

We can write two equations in the two unknowns using the given relations. Let g and b represent the costs of a round of golf and a turn in the batting cage, respectively.

  5g +4b = 60 . . . . . Sylvester's expense

  3g +6b = 45 . . . . . Lin's expense

Dividing the second equation by 3 gives ...

  g +2b = 15   ⇒   2b = 15 -g

Substituting into the first equation, we have ...

  5g +2(2b) = 60

  5g +2(15 -g) = 60 . . . . . substitute for 2b

  3g = 30 . . . . . . . . . subtract 30, collect terms

  g = 10 . . . . . . . divide by 3

__

  2b = 15 -10 = 5 . . . . use the value of g to find b

  b = 2.5 . . . . . . . . divide by 2

Mini golf costs $10 per round; batting cages cost $2.50 per turn.

Olivia picked 256 strawberries from the orchards fields. she divided the strawberries evenly into 6 baskets. how many strawberri
Fofino [41]

Answer:

42 strawberries are in each basket. 4 strawberries are left over.

Step-by-step explanation:

To find out how many she put into each basket, you need to divide 256/6. Your answer should 42.6666667. Round down to 42.

To find out how many are left over, multiply 42 x 6. You need to do this to figure out how many strawberries total she used trying to put them evenly into the baskets. Your answer should be 252. Then, you subtract 256 - 252. You do this to find out how many are left over. Your answer is 4.
