Ruby had 30 dollars to spend on 3 gifts. She spent 9 7 10 dollars on gift A and 5 2 5 dollars on gift B. How much money did she have left for gift C?
From the above question,
$30 = Gift A + Gift B + Gift C
She spent 9 7/ 10 dollars on gift A and 5 2/5 dollars on gift B.
$30 = $9 7/10 + $5 2/5 + Gift C
Gift C = $30 - ( $9 7/10 + $5 2/5)
Lowest Common Denominator = 10
Gift C = $30 - $14+(7 + 4/10)
Gift C = $30 - $14+(7 + 4/10)
Gift C = $30 - $14+(11/10)
$30 - $14+(1 1/10)
$30 - $15 1/10
Gift C = $14 9/10
Therefore, the amount of money she had left for gift C is $14 9/10
Unknown: X
Expression B = 8 Expression A
X×[(1.5+100.25)x3.65]=8 {<span>4×[(1.5+100.25)x3.65]}
</span>X×[(1.5+100.25)x3.65]=32×[(1.5+100.25)x3.65]
Comparing the two expressions, X=32
Answer: The <span>number belongs in the box in Expression B is 32</span>
Based on the time taken by the jet when flying with the wind versus against it, the rate of the jet and jet streams are:
- In still air = 1,170 mph
- Rate of wind = 170 mph
<h3>What is the speed of the jet?</h3>
The speed of the jet flying against the wind is:
= 3,000 / 3
= 1,000 mph
The speed with the jet stream is:
= 5,360 / 4
= 1,340 mph
Assuming the speed of the jet is x and the rate of wind is y, the formulas are:
x - y = 1,000
x + y = 1,340
Solving gives:
2x = 2,340
x = 1,170 mph
The rate of jet stream is:
x - y = 1,000
1,170 - y = 1,000
y = 170 mph
