Answer:
a. 0.69x + 0.14
b. 5.67 - 30.48a
c. 1.1x - 3.01y
Step-by-step explanation:
a) 2.56x + 0.14 − 1.87x
<em>To simplify this algebraic expression, you start by collecting like terms;</em>
2.56x − 1.87x + 0.14
<em>Then perform arithmetic operation</em>
0.69x + 0.14
b) 7.32a + 2.1 (2.7 − 18a)
<em>Here; first, the bracket must be opened</em>
<em>To open the bracket; each expression in the bracket is multiplied by 2.1. This leaves us with</em>
7.32a + 2.1 * 2.7 − 2.1 * 18a
7.32a + 5.67 - 37.8a
<em>Then, you collect like terms</em>
7.32a - 37.8a + 5.67
<em>Then perform arithmetic operation</em>
-30.48a + 5.67
<em>Rearrange</em>
5.67 - 30.48a
c) 0.12x + 0.34y + 0.98x − 3.35y
<em>Here, you start by collecting like terms</em>
0.12x + 0.98x + 0.34y − 3.35y
<em>Then perform arithmetic operation</em>
1.1x - 3.01y
Answer:
The answer would be B. With equations, what you do to one side you have to do to the other.
22.50-3.75= 18.75
18.75/1.25= 15
1.25 × X = total money left after purchases.
A unit rate is any quantity's value with respect to another. An example is speed expressed in kilometers per hour which is used to measure how fast a vehicle is traveling.
15*5=75
79-75=4
If Luis gives each of his classmates 5 pencils each, he will have 4 leftover to give to his teacher
16*4=64
79-64=15
If Luis gives himself AND each of his classmates 4 pencils each, he will have 15 leftover to give to his teacher
So... If Luis decides to take an equal share of pencils along with his classmates, his teacher will receive more pencils.
