Answer:
874×1 = 874
874×10 = 8,740
874×100 = 87,400
874×1,000 = 874,000
Step-by-step explanation:
The equation that can be used to determine the tax rate, x is ;44.31 = 42 + (x% of 42) where x = 5.5%
<h3>How to write equation</h3>
- Cost of a shirt = $12.50
- Cost of each shorts = $14.75
- Cost of two shorts = 2 × $14.75
= $29.5
- Total cost = $12.50 + $29.5
= $42
- Total amount paid = $44.31
Total = total cost + x% of total cost
44.31 = 42 + (x% of 42)
44.31 = 42 + 42x/100
44.31 - 42 = 42x/100
2.31 = 42x / 100
x = 2.31 ÷ 42/100
= 2.31 × 100 /42
= 231/42
= 5.5%

Answer:
50% of 6/5 = 3/5
Step-by-step explanation:
Remember that 50%=1/2
Therefore, 50% of 6/5 = 1/2*6/5=6/10=3/5
We can use ratios to find the answer to this.
Set up the ratio.
3/4 / 18/7 = x / 1
Multiply both sides by 1
3/4 / 18/7 = x
Inverse 18/7 to 7/18 so we can multiply.
3/4 * 7/18 = x
Multiply.
21/72 = x
Simplify7/24 = x
Therefore, 7/24 cups of oats is used per pound.
One number = x
Another number = y
x = y + 5
x + y = 37
(y + 5) + y = 37
2y + 5 = 37
2y = 32
y = 16
x = (16) + 5
x = 21
The numbers are 16 and 21.
