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:

B) x = 20

Step-by-step explanation:

The formula for finding the missing side of a right triangle is: a^2+b^2=c^2.

C represents the longest side of the right triangle, so if we plug in the given lengths, we can solve: 12^2 + 16^2 = x^2

Solve the exponents: 144 + 256 = x^2

Add: 400 = x^2

Find the square root: 20 = x

Answer: 4x +10

Step-by-step explanation:

you just need to multiply the inside of the brackets by the outside so 2x x 2 = 4x and 5 x 2 = 10

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

a= -2b

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:

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:

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:

If we put all of it together we have the factors :2 x 5 x 5 x 7 = 350.

Step-by-step explanation:

It can also be written in exponential form as 21 x 52 x 71.

Hope this is helpful .

Answer:

Step-by-step explanation:

draw the prime factor tree of 350

you can choose any 2 numbers that equals 350, then continue in that way by choosing any 2 numbers that equals the number that's on top of the 2 other numbers when multiplying, except 1×number, because it won't help you to get the prime factors of a specific number, unless it's a prime number so you don't need to multiply by any number

                                                             350

                                                     35             10

                                                 5        7       2     5

350=2×5×5×7

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

Step-by-step explanation:

Answer:

42

Step-by-step explanation:

in order to find y, we need to find x.

180-65-62=53

x=53

we need to subtract 53-?=11

53-42=11

y=42

Answer:

42

Step-by-step explanation:

because the triangles are congruent, we can place the angle x in CDE to solve for it. Knowing the sum of all angles in a triangle is 180, we can set up the formula below.

62 + 65 + x = 180

Additionally, because the triangles are congruent, we know that the length of CD is equal to GH, letting us set up this formula:

x - y = 11

Solving the first formula, we now know the value of x, 53.

62 + 65 + 52 = 180

Plugging that into the second formula and solving, we get 42.

53 - 42 = 11
