Answer:
56 + 7d
Step-by-step explanation:
For using the distributive property, You have to multiply the first number to the rest. So 8 x 7 = 56 and 7 x d = 7d.
Answer:
Step-by-step explanation:
1) 17x + 175 = y
2) 17(28) + 175 = y
476 + 175 = y
651 = y
Cost for bus and 28 students is $651
3) 889 - 175 = 714
714/ 17 = 42
42 students attempted the trip
Answer:
Step-by-step explanation:
x>5
First you distribute the 2 to the X and the -7 so the equation becomes 8x+2x-14=7x+3x-14 you then combine like terms and the equation becomes 10x-14=10x-14. you then add 14 to one side and get 10x=10x+0 or just 10x=10x, and then you subtract 10x from both sides and get 0, no solutions.
b) you used the distributive property in the begining of solving the equation.
