Mathematics
1 answer:
mihalych1998 [28]2 years ago
4 0

Answer:

D. 6

Step-by-step explanation:

Let's first find x :-

\sf 3 + 2x + 22 = x + 17

  • \sf 2x + 25 = x + 17
  • \sf 2x - x = 17 - 25
  • \sf x =  - 8

Now that we found x, let's find QR :-

QR = 2x + 22

  • \sf QR = 2( - 8) + 22
  • \sf - 16 + 22
  • \sf 6

Therefore, QR = 6 !!!

Jenny is throwing a surprise birthday party for her best friend Katie. She has decided to make Katie’s favorite dish, meat loaf.
miskamm [114]

Answer:

The answer is below

Step-by-step explanation:

a) The recipe for the meat loaf used by Jenny can serve a total of 8 people. Since there are 40 people in total to serve, the number of each ingredient needed is:

Number of each ingredient = total number of people / number of people served by one recipe

Number of each ingredient = 40 / 8 = 5

b) Since each recipe contains 1 1/2 lb (1.5 lbs) of ground beef, the total amount of ground beef needed to feed everyone is:

Total amount of ground beef = 1.5 lbs * 5 = 7.5 lbs

c) Since one serving would require 8 oz of milk. To serve everyone, the amount of milk needed is:

Amount of milk = 40 people * 8 oz = 320 oz

128 oz = 1 gallon

Amount of milk = 320 oz * 1 gallon / 128 oz = 2.5 gallon

Sergio039 [100]

Answer:

x =  - 4

Step-by-step explanation:

4x - 2 =  - 3 \times 2 + 3x

Calculate the product:

4x - 2 =  - 6 + 3x

Rearrange the terms:

4x - 3x =  - 6 + 2

Combine like terms:

x =  - 6 + 2

Calculate:

x =  - 4
