john makes $8 an hour walkin dogs and 16 an hour as a math tutor this weekend he wants to work no more than 10 hours he also wan
lawyer [7]

This question can be solved using an Algebraic equation.

The system of equations is given as:

x + y ≤ 10

8x + 16y ≥ 96

Let's represent

x = number of hours he walks the dogs

y = number of hours he works as a maths tutor

John must work for no more than 8 hours walking the dog and 2 hours as a Maths tutor to earn at least $96.

Our system of equations is given as:

He wants to work no more than 10 hours.

No more is represented by the inequality "≤ " = Less than or equal to

x + y ≤ 10 ...........Equation 1

He also wants to earn at least 96.

At least is represented by the inequality" ≥" = Greater than or equal to

$8 × x + $16 × y  ≥ 96

8x + 16y ≥ 96........Equation 2

Solving for the number of hours

x + y = 10

x = 10 - y

Substitute 10 - y for x in Equation 2

8(10 - y) + 16y = 96

80 - 8y + 16y = 96

Collect like terms

8y = 96 - 80

8y = 16

Divide both sides by 8

8y/8 = 16/8

y = 2 hours

Solving for x

x = 10 - y

x = 10 - 2

x = 8 hours

Therefore, John must work for no more than 8 hours walking the dog and 2 hours as a Maths tutor to earn at least $96.

7 times a number equals 3 less than 5 times that number. what is the number?
inessss [21]

First the equation would look like this:

7n = 5n - 3

7n - 5n = 5n - 5n - 3   -Subtract 5n from both sides.  Which gives you...

2n = -3      

2n/2 = -3/2          -Divide both sides by 2

n = -1.5

Hope this helps!

Your instructor has 50 questions on a quiz and the are 2 points a peice. The maxium score is 100. and you miss 11 of these quest
Bess [88]

Answer:

78

Step-by-step explanation:

50 questions worth 2 a piece and you miss 11 questions so we are going to take 2(11) off of 50.

We are doing 100-2(11).

100-22=78.

Or if you miss 11 questions you get 39 right. So 39(2)=78.
