 Let x be the number of miles he travelled on the  first day
Then on the second day he travelled  x / 1.5 miles
so we have the equation

x + x/1.5 = 1380

multiply through by 1.5:-
1.5x + x = 2070
2.5x = 2070
x = 2070 / 2.5 = 828 miles answer

Its C

Answer:

x = 3

Step-by-step explanation:

6x -4(3x-5) = 2

I need answer please​
zhenek [66]

Answer:

We know that lines <em>l</em><em> </em>and <em>m</em><em> </em>are parallel. The alternate interior angles rule states that the alternate interior angles formed by parallel lines are equal. So let's equate them.

2x + 22 = 4x

putting variables on one side,

22 = 4x - 2x

Thus 2x = 22

x becomes 22÷2

Therefore,<u> x = 11.</u>

Amlyah increased her bench press
NikAS [45]
<h3>Answer:  20% increase</h3>

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

Explanation:

A = old value = 110

B = new value = 132

C = percent change

C = 100*(B-A)/A

C = 100*(132-110)/110

C = 20%

The positive C value means we have a percent increase, which corresponds to the fact that A = 110 increases to B = 132.

The B-A = 132-110 = 22 portion up top indicates that the increase is 22 pounds, which when divided over 110, gets us 22/110 = 0.20 = 20%

---------------

Checking the answer:

20% of 110 = 0.20*110 = 22

She's able to lift 22 extra pounds on top of the 110 pounds she can handle previously, so she can now lift 110+22 = 132 pounds. The answer is confirmed.

A family went to a baseball game. The cost to park cars was $5 and the cost per ticket was $21. Write a linear function in the f
Sophie [7]

Answer:

The total cost y in dollars of going to the baseball game for x people of a family can be given as:

y=21x+5

Step-by-step explanation:

Given:

At a baseball game:

Cost of car parking = $5

Cost per ticket = $21

To write an equation in the form of y=mx+b representing the total cost of going to the baseball game.

Solution:

The total number of people in the family is = x

Using unitary method to find the cost of tickets for x persons.

If 1 ticket costs = $21

<em>Then, x tickets will cost in dollars</em><em> = </em>21x

Fixed rate for car parking = $5

Thus, the total cost y in dollars of going to the baseball game for x people of a family can be given as:

y=21x+5

Initial cost (PV)= $500

Decrease rate (d)= 7% per year

Number of periods (n)= 2 years

<u>To calculate the future value after 2 years, we need to use the following formula:</u>

FV= PV / (1 + d)^n

FV= 500 / (1.07^2)

FV= $436.72
