Step-by-step explanation:

7=×+9

×=9-7

×=2

as we were told tht the value of y=7 which means where the is y we subsitude 7

which will give us 7=×+9

The addition of 9 is positive and 7 is positive, then when jumping the equal sign it shall be negative therefore 9-7=2

Answer:

2)

a. x= -84

b. x= 9/4 or 2.25 in decimal form

c. x= 53/5 or 10.6 in decimal form

d. x= 31/2 or 15.5 in decimal form

3)

a. y= -10

b. y= -28

c. y= -114

d. y= 68

Step-by-step explanation:

2) substitute y as 7

a. y= x+91

7=x+91

7-91=x

-84=x

x= -84

——————

b. y= 4x-2

7=4x-2

7+2=4x

9=4x

9/4=x

x=9/4 or 2.25

————————

c. y= 5x-46

7= 5x-46

7+46=5x

53=5x

53/5=x

x=53/5 or 10.6

—————————

d. y= 6x-86

7= 6x-86

7+86=6x

93=6x

93/6=x

31/2=x

x= 31/2 or 15.5

—————————

3) substitute x as 13

a. y= -x+3

y= -13+3

y= -10

——————

b. y= -2x-2

y= -2(13)-2

y= -26-2

y=-28

——————

c. y= -3x-75

y= -3(13)-75

y= -36-75

y= -114

——————

d. y= 8x-36

y= 104-36

y= 68

The total amount needed is $165 if your class earned $55.00 Saturday afternoon by washing cars to raise money for a class trip.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

Your class earned $55.00 Saturday afternoon by washing cars to raise money for a class trip. This is 1/3 of the money needed for the trip.

Let x be the total amount needed:

A linear equation in one variable can be framed as follows:

1/3 of x = 55

x/3 = 55

x = 55x3

x = $165

Thus, the total amount needed is $165 if your class earned $55.00 Saturday afternoon by washing cars to raise money for a class trip.

Answer:

Answer:The formula for the area of a parallelogram is A = bh, and the formula for area of a triangle is A = 1/2bh. Since a triangle is half of the area of a parallelogram with the same base and height, the only difference in the formula is 1/2.

Step-by-step explanation:

Maria would determine the height by dividing the area of the garden by the base

From the question, she has the area and the base.

Also, the garden has the shape of a parallelogram

The area of a parallelogram is the product of the base and the height.

So, when the area is divided by the base, she gets the height

Q6)

Kerry's workday is 10 hrs. and works 40 hrs. per week, Kerry works for 4 days

Watson's workday is 8 hrs. and works 40 hrs. per week, Watson works for 5 days

Kerry: works 4 days and gets paid $ 12.75 per cat & grooms 15 cats per day, so Kerry makes = 4(12.75 × 15) = 4(191.25) = $ 765

Watson: works 5 days and gets paid $ 12.75 per cat & grooms 10 cats per day, so Watson makes = 5(12.75 × 10) = 5(127.50) = $ 637.50

∴ The difference between their weekly earning is 765 - 637.50 = $ 127.50
