How to use techniques of adding the additive inverse and multiplying by the Students use algebra to solve equations (of the form px + q = r and p(x + q) = r where p pay with a $10 bill and receive no change, then how much did each bottle of a. If Allen buys 4 uniform shirts at one time, he gets a $10 discount so that the
Answer: In step 1, Andrew used the commutative property
Explanation:
In step 1 he used commutative, which is a + b = b + a
(- 5.7 + 2.2) = 2.2 + (- 5.7)
Step 2, he used associative property, not the distributive.
Step 3, he just added5.7 + 1.1 = 6.8
Step 4, he distributed the negative sign:
- (6.8) = - 6.8
after 4 weeks:
.3*4= 1.2 saved
then it is doubled
1.2*2 = 2.40
8 weeks
he will have saved for 4 more weeks ( week 5 6 7 8)
4 * .3 = 1.2 saved
2.4 + 1.2 = 3.6 saved
then it is doubled
3.6 * 2 =7.20
he will have saved for 4 more weeks ( week 9, 10, 11, 12)
4 * .3 = 1.2 saved
7.2+ 1.20=8.40
then it is doubled
8.4*2 = 16.8
He will have 16.80 after 12 weeks
