Please help don't understand at all​
Levart [38]

(i) Note that it is given to you that 3a + 2b = 9

You are trying to find the value of 9a + 6b. Find what is multiplied to both the variable a & b. Divide:

(9a + 6b)/(3a + 2b) = 3

Next, multiply 3 to the 9 on the other side of the equation:

3 x 9 = 27

27 is the value of 9a + 6b.

(ii) Note that it is given to you that 8x + 6y = 60

You are trying to find the value of 4x + 3y. Find what is multiplied to both the variable x & y. Divide:

(8x + 6y)/(4x + 3y) = 2

Next, divide 2 from the 60 on the other side of the equation:

60/2 = 30

30 is the value of 4x + 3y.

Which numbers are necessary to solve this problem?
SSSSS [86.1K]

Answer:

A

Step-by-step explanation:

A: 3 times a week, 45 minutes, 15 minutes, 4 weeks

In the beginning of the word problem it says Brian goes to the gym 3 times a week. We need to know that because you have to use that number later for multiplication.

The 45 minutes are important because he spends 45 minutes at the gym each visit.

The 15 minutes are important because you have to subtract that from 45 because 15 of the 45 minutes are spent on weights, the rest of the time is spent on the treadmill, and we need to know how long Brian is on the treadmill in 4 weeks.

So the equation should be: [(45-15)* 3]*4

Solution step-by-step:

45-15= 30 minutes for treadmill

30*3=90 minutes per week

90*4= 360 minutes in 4 weeks

Convert into hours:

360 minutes/60 minutes= 6 hours

Hope this helps!!! :D
