Step-by-step explanation:
step 1. if the distributive property works for 3*(5+ -5) then since 5 + -5 = 0 then 3*0 =0
step 2. let's give it a try
step 3. 3*(5 + -5) = 3*5 + 3*(-5) distributive property
step 4. 15 + -15 = 15 - 15 = 0 (yes it works).
80 degrees. Angle CBD and angle BFH are corresponding so they are equal. Angles on a straight line add up to 180 degrees. 180-100=80
Answer:
X4
Step-by-step explanation:
1. The first step is Distribution, a = 10a - 14. You can determine this by multiplying 2 into (5a - 7). 2*5a =10a, while 2*- 7 = - 14. Resulting in, a = 10a - 14.
2 . Now, subtract 10a on both sides, meaning 10a - 10a and a - 10a. The equation simplified is - 9a = - 14.
3. Divide by - 9 on both sides. The solution to the equation is a = 14/9
He will have left $347.8 left
