Question

1. (3 x 5) + (6 x 5) = (16 x 5) – (________ x 5) 2. (3 x 8) + ( ________ x 8) = 13 x 8

Answer 1

1. x3+x5=16. Multiply each side by 3: x+3x5=48. Continue simplifying and solving: 5x5+3x5=48. 8x5=48. 8x=240. x=30.

2. –7 x 8. –60. 3 ... You need to read the problem and know what information you (3 x 5) + (6 x 5) = (16 x 5) – (________ x 5(3 x 8) + ( ________ x 8) = 13 x 8

Answer 2

Answer:

(3 x 5) + (6 x 5) = (16 x 5) – (7 x 5)

(3 x 8) + (10 x 8) = 13 x 8

Step-by-step explanation:

(3 x 5) + (6 x 5) = (16 x 5) – (________ x 5)

(15) + (30) = 80 – ( ____ x 5)

45 = 80 – ( ____ x 5)

We need to subtract 35 from 80 for it to equal 45

7 x 5 = 35, so fill in 7 in the blank

45 = 80 – (7 x 5)

45 = 80 – 35

45 = 45

(3 x 8) + ( ________ x 8) = 13 x 8

(24) + ( _______ x 8) = 104

We need to add 80 to 24 for it to equal 104

8 x 10 = 80, so fill in 10 in the blank

(24) + (10 x 8) = 104

(24) + (80) = 104

104 = 104
