PLEASE HELP ME ASAP?!?
Find the length of the missing side. Simplify all radicals.

Answer:

2x squared - 8

Step-by-step explanation:

For this kind of equation, we use the distributive property

So in the image below I used a box method (that's how I learned it in school)

So since -4x and 4x cancel each other out, or amount to 0, we don't put anything for those. So the equation left is 2x squared - 8

Answer: 18 pies, 22 cakes

Step-by-step explanation:

Let the number of pies sold be represented by p.

Let the number of cakes be represented by c.

The information in the question can then be represented in an equation as:

p + c = 40 ........ i

10p + 8c = 356 ....... ii

Multiply equation i by 10

Multiply equation ii by 1

10p + 10c = 400 ....... iii

10p + 8c = 356 ....... iv

Subtract iv from iii

2c = 44

c = 44/2

c = 22

22 cakes were sold

Since 40 items were sold, the number of pies sold will be:

= 40 - 22

= 18 pies

Answer:

Ruby needs 7 combined.

Step-by-step explanation:

If she needs 1/4 cup of powdered milk for one batch, then we multiply 1/4 by 4 to see how much she needs for 4 batches, which is 4/4, or one whole.

If she needs 3/2 cups of whole wheat for one batch, then we multiply 3/2 by 4 to see how much she needs for 4 batches, which is 12/2, or 6.

Then we combine 6 and 1, which is 7.

Answer:

786 feet per min

Step-by-step explanation:

60 (mins in an hour) x 4= 240 mins

there are 5240 feet in a mile

5240 (feet in a mile) x 36= 188640

188640 divided by 240= 768

Answer:

x = 4

y = 3

Step-by-step explanation:

2x - 3(x - 1) = -1

2x - 3x + 3 = -1

-x + 3 = -1

   - 3     - 3

(-1) -x = -4 (-1)

x = 4

y = 4 - 1

y = 3

Answer:

x = 4, and y = 3

Answer: i assume you're looking for F, if so F = -16

Step-by-step explanation:

you would start by adding +24 to each side of the equation, giving you f/4 = -4

then, you would multiply each side of the equation by 4, giving you f = -16

Answer:

Devante is 23 and Savannah is 32.

Step-by-step explanation:

We can set up a system of equations.

s - savannah's age

d - devante's age

s = d + 9

s + d = 53

Now we can substitute (d + 9) for s in the second equation.

(d + 9) + d = 53

2d + 9 = 53

2d = 46

d = 23

To find Savannah's age, we just add 9 to Devante's age. (plugging in 23 for d)

23 + 9 = 32

s = 32

Answer:

y=1

Step-by-step explanation:

Let's solve your equation step-by-step.

5(2y−3)−4y=8−2y−15

Step 1: Simplify both sides of the equation.

5(2y−3)−4y=8−2y−15

(5)(2y)+(5)(−3)+−4y=8+−2y+−15(Distribute)

10y+−15+−4y=8+−2y+−15

(10y+−4y)+(−15)=(−2y)+(8+−15)(Combine Like Terms)

6y+−15=−2y+−7

6y−15=−2y−7

Step 2: Add 2y to both sides.

6y−15+2y=−2y−7+2y

8y−15=−7

Step 3: Add 15 to both sides.

8y−15+15=−7+15

8y=8

Step 4: Divide both sides by 8.

The value of y is 1

Given the equation 5(2Y - 3) – 4y = 8 – 2y - 15

Expand

10Y - 15– 4y = 8 – 2y - 15

6y - 15 = -7 - 2y

Collect the like terms

6y + 2y = -7 + 15

8y = 8

Divide both sides by 8

8y/8 = 8/8

y = 1

Hence the value y of is 1
