Answer: 8
Step-by-step explanation:
QS = RS + QR
3x = 2x + 3x-8
3x = 5x - 8
8 = 2x
8/2 = x
4 = x
RS = 2x = 2(4) = 8
Answer:

Option B
2 notebooks for $ 0.60 expressed as unit rate is $ 0.30 per notebook
<h3><u>Solution:</u></h3>
We have to express ratio as unit rate
Given that, 2 notebooks for $ 0.60
Number of notebooks = 2
Cost of 2 notebooks = $ 0.60
So we have to find cost of 1 notebook
So unit rate = cost of 1 notebook = $ 0.30
So 2 notebooks for $ 0.60 as unit rate is $ 0.30 per notebook
If you would like to know what is 5 * (a + 3) in algebra, you can calculate this using the following step:
5 * (a + 3) = 5 * a + 5 * 3 = 5 * a + 15
The correct result would be 5 * a + 15.
Step-by-step explanation:
(a)90 by 10%
90+10% of 90=90(1+0.1)=99
(b)60 by 25%
60(1+0.25)=75
(c)80 by 75%
80(1+0.75)=140
(e)110 by 60%
110(1+0.6)=176
(f)480 by 115%
480(1+1.15)=1032
(g)140 by 45%
140(1+0.45)=203
