Answer:

1.. 9x +6 _ 7x =_8

9x _7x = _8 _6

2x =_14

divide both sides by 2 and your answer is

x = _7

2. -3x-32 = -10 +8x

-3x -8x = -10 +32

-11x = 22

divide both sides by -11 and your answer is

x= -2

logan recieved a raise of $5 per hour. He made $12 per hour before the raise. By what percent did his salary increase? Round to
Nikitich [7]

This is pretty basic, but you need to convert the percentage into a real number that you can use to multiply by the employee’s current pay rate. To do this, simply move the decimal two places to the left. For a 3% increase, you will use .03.

Step 2: Multiply the employee’s current pay rate by that decimal

If your employee makes $15/hour, then you have: 15x.03=.45. So your employee’s increase is 45 cents per hour. For an employee who makes a salary of $45,000/year, then you have: 45,000x.03=1,350. So your salaried employee’s pay increase is $1,350 per year.

Why You Have to Convert the Percent

This is just a little theory and not needed to do the problem.

The percent symbol is used to tell you something about the number it sits beside. Percent means ‘parts per hundred’. So if a % sign sits beside a 3, it really means 3 parts per 100. You don’t need to know this to calculate a pay increase but it might help you to understand why you need to convert the percent into decimal form to begin with. 3% tells us we need to multiply our pay rate by 3 pieces of a hundred.

Do you remember what the decimal places mean? The first decimal place is the tenths place and the second is the hundredths place. This is why when we convert our percent we have to move two places – we have to open up the hundredths place.

Mrs.Willy bought 3 1/2 pounds of ground turkey and 2 1/2 pounds of white fish the white fish is $4.60 per pound cheaper than the
Sophie [7]

Answer:

the price per pound she paid for the ground turkey = $10.515

the price per pound for the white fish

= $5.915

Step-by-step explanation:

Let x = cost of one pound of ground turkey.

Let y = cost of one pound of white

fish

Mrs.Willy bought 3 1/2 (7/2) pounds of ground turkey and 2 1/2(5/2) pounds of white fish and she paid a total of $51.59. This means

7x/2 + 5y/2= 51.59 - - - - - - -1

the white fish is $4.60 per pound cheaper than the ground turkey. This means

y = x - 4.60

To find the price per pound she paid for the ground turkey and the price per pound for the white fish,

substitute y= x - 4.60 in equation 1

7x/2 + 5y/2= 51.59

3.5x +2.5y = 51.59

3.5x + 2.5(x-4.6) = 51.59

3.5x + 2.5x - 11.5= 51.59

6x = 51.59+11.5= 63.09

x = 63.09/6 = $10.515

Substituting x = 10.515 in equation y = x - 4.60,

y = 10.515-4.60

= $5.915

5a (b - c) = d Solve for b
Allisa [31]
Solve for b:
5 a (b - c) = d
Divide both sides by 5 a:
b - c = d/(5 a)
Add c to both sides:
Answer:  b = c + d/(5 a)
