Answer:

y = 7/50

Step-by-step explanation:

-5y + 56y - 32 = -7 - 18 + y

50y = -25 + 32

50y = 7

y = 7/50

Answer:

[tex] \frac{1}{2} [/tex]

Step-by-step explanation:

Open the bracket

[tex] - 5y + 56y - 32 = 7 - 18 + 9y[/tex]Collect the like terms

[tex]51y - 9y = - 11 + 32[/tex]

[tex]42y = 21[/tex]

Divide both sides by 42

[tex]y = \frac{21}{42} [/tex]

Lila and Drew want to buy their mom a gift that costs $30. Raquel has $18 saved already, how much does Drew need to save to pay for the gift?

Let d = the amount that Drew has to save to help buy the gift.

Which equation can be used to solve the problem. Equation

How much money does Drew need to save so they could buy the gift?















Answers

A number decreased by 11 is equal to 48

x - 11 = 48

Lila and Drew:

18 + d = 30

To solve, subtract 18 from both sides of the equation. That gives you:

d = 12

Drew needs to save $12

Step-by-step explanation: So since the dimensions are easy to calculate, just multiply 9 by 4 and 15 by 3, then you get 36 and 45. Multiply 36 by 45 and you get 1620, but since the vacuum can get 2 square ft, then divide by 2 and you get 810. Since it takes 8 minutes to clean up, multiply 810 by 8 and you get 6480. I do believe

The area of a circle is 81 pi in2 what is the circumference in inches express ur answer in terms of pi

Answers

Answer:

Circumference of circle = 18π inches

Step-by-step explanation:

Given the following data;

Area of circle = 81π in²

To find the circumference;

First of all, we would find the radius of the circle using the area of circle formula.

Area of circle = πr²

Substituting into the formula, we have:

81π = πr²

Dividing both sides by π, we have;

81 = r²

Taking the square root of both sides, we have;

r = 9 inches

Now, to find the circumference of the circle;

Circumference of circle = 2πr

Circumference of circle = 2*π*9

Circumference of circle = 18π inches.

After a very successful year, Cheap-Rentals raised salaries by a scale factor of `\frac{11}{10\ }`. If Luan now makes $14.30 per hour, what did she make before?

Answers

Answer:

$13

Step-by-step explanation:

Given that :

Increase in salary factor = 11/10

New salary = $14.30

Initial salary = x

To obtain the value of the initial salary,

The product of the scale factor by the initial salary sgiuf give the amoi tof the new salary

11 / 10 * x = 14.30

1.1x = 14.30

x = 14.30 / 1.1

x = $13

Hence.initial salary per hour = $13

Determine the value of x in each figure.

Hello There!

The shown angles have a sum of 90 degrees

This is noticeable because there is a square at the vertex which indicates that its a right angle

A right angle has a measure of 90 degrees

That being said we can create an equation to solve for x

90 = 66 + 8x having made an equation we now solve for x

step 1 subtract 66 from each side

90 - 66 = 24

66 - 66 cancels out

now we have

24 = 8x

step 2 divide each side by 8

8x/8=x

24/8=3

we're left with x = 3

Answer:

x=3

Step-by-step explanation:

8x+66=90 complement

8x=90-66

10) A circle has center at (-5, 3) and passes through the point (-1, 3).
a) Give the radius of the circle.

b) Give the equation of the circle described.

Answers

a) radius= 4 units

b) (x+5)^2+(y-3)^2=4^2

The distance between the x values in the center point and a point included in the graph will give you the radius.
The x values are 4 units apart (-5 to -1) so your radius is 4 units

Circle formula:
(x-h)^2+(y-k)^2=r^2
Where (h,k) is the center point and r is the radius

Replace h with -5, k with 3, and r with 4 to get equation listed in answer above

#8 A boogie board that has a regular price of $70 is on sale at a 35% discount. Find the selling price.

Answers

245. So you do 7x35.

Answer:

45.5

Step-by-step explanation:

To find 35% of 70, you have to use the equation...

70 x 35/100

70 x 35 = 2,450

2,450/100 = 24.5

24.5 is 35% of 70, so the item is now $24.5 less than the original price.

70 - 24.5 = 45.5

The selling price is $45.5
