Answer:
Step-by-step explanation:
8x+5=29, x=3
subtract 5 on each side
8x=24
then divide by 8 on both sides to isolate x
x=3
Answer:
<u>1. The number is 71.3</u>
<u>2. The number is 127.1</u>
<u>3. The number is 230</u>
<u>4. The number is 34</u>
Step-by-step explanation:
Let's find out the numbers, x, for each case:
1. 5% of it is 5% of it is 23% of 15.5
5% = 0.05
23% of 15.5 = 0.23 * 15.5 = 3.565
Then, we have:
0.05x = 3.565
x = 3.565/0.05
x = 71.3
<u>The number is 71.3</u>
2. 4% of it is 31% of 16.4
4% = 0.04
31% of 16.4 = 0.31 * 16.4 = 5.084
Then, we have:
0.04x = 5.084
x = 5.084/0.04
x = 127.1
<u>The number is 127.1</u>
3. 4.5% of it is 23% of 45
4.5% = 0.045
23% of 45 = 0.23 * 45 = 10.35
Then, we have:
0.045x = 10.35
x = 10.35/0.045
x = 230
<u>The number is 230</u>
4. 5.5% of it is 17% of 11
5.5% = 0.055
17% of 11 = 0.17 * 11 = 1.87
Then, we have:
0.055x = 1.87
x = 1.87/0.055
x = 34
<u>The number is 34</u>
Answer:
3
Step-by-step explanation:
1/5 × 15
= 15/5
