In triangle PQR, measurement P = 7x+8 , measurement Q = 8x-10, and measurement R = 7x+6 . List the sides in order from shortest
astra-53 [7]

Answer:

QRP

Q = 8x-10

R = 7x+6

P = 7x+8

Step-by-step explanation:

Let x be any positive integer, say x=2

P=7x+8=(7*2)+8=22 units

Q=8x-10=(8*2)-10=6 units

R=7x+6=(7*2)+6=20 units

From the above, Q is the shortest and P is the longest side. Therefore, the sides arranged from shortest to longest will be Q, R, P

An apple contains 165 calories and 3 g of fiber. A banana contains 120 calories and 2 g of fiber. Set up a system of equations t
Aleks04 [339]

Answer:

The answer to your question is:  22 apples and 12 bananas

Step-by-step explanation:

a = apples

b = bananas

                     165a + 120b = 5070

                       3a + 2b = 90

Solve by elimination

                 -60(3a + 2b = 90)

                -180 a - 120b = -5400

                 165a + 120b = 5070

                  -15 a      0    = -330

                        a = -330 / -15

                         a = 22

                  3(22) + 2b = 90

                  66 + 2b = 90

                  2b = 90 -66

                   2b = 24

                   b = 24/2

                   b = 12

Watson and Alva each have the same total number of toy cars and trucks Watson has 4 boxes. Each of his boxes has 7 cars and 2 tr
bulgar [2K]

<u>Answer:</u>

Alva has 7 trucks in each box.

<u>Explanation:</u>

You need to determine the total number of toys Watson has. Watson has 4 (7+2) = 4(9) = 36 toys.

  • Set 36 equal to an expression for the number of toys Alva has. Using t for the number of trucks, 36 = 2 (11+t).

Then, solve the equation.

  • 36 = 2(11+t) 36 = 22 + 2t 14 = 2t7 = t

So how many trucks are in each of Alva's boxes?

  • 7 Trucks!
