Combining like terms

Mathematics
1 answer:
MAXImum [283]3 years ago
4 0

Combine like terms to simplify an expression. For example, all terms with the variable x can be combined into one term. All constants can also be combined.

1) -4x - 10x = -14x

2) -r - 10r = -11r

3) -2x + 11 +6x = 4x + 11

4) 11r - 12r = -r

5) -v + 12v = 11v

6) -8x - 11x = -19x

7) 4p + 2p = 6p

8) 5n + 11n = 16n

9) n + 4 - 9 - 5n = -4n - 5

10) 12r + 5 + 3r - 5 = 15r (the 5 and -5 cancel each other out)

11) -5 + 9n + 6 = 9n + 1

Nicole has $120. if she saves $20 per week, in how many days will she have $500?
ElenaW [278]
500= 120+20x, where x is weeks

Subtract 120 from both sides
380=20x

Divide both sides by 20
19=x

19 weeks*7 days per week= 133 days

Final answer: 133 days

Solve for y: 2½y = ⅝ Answer in simplest form.
MrMuchimi
<h2>1/4 or 0.25</h2>

Step-by-step explanation:

2 \frac{1}{2} y =  \frac{5}{8}

Convert Mixed number to improper fraction.

2 \frac{1}{2}  =  \frac{5}{2}

Equate

\frac{5}{2} y =  \frac{5}{8}

Cross Multiply

5y \times 8 = 2 \times 5 \\ 40y = 10

Divide both sides of the equation by 40

\frac{40y}{40}  =  \frac{10}{40}

Simplify

y =  \frac{1}{4}
