The equation relating length to width
L = 3W
The inequality stating the boundaries of the perimeter
LW <= 112
When you plug in what L equals in the first equation into the second equation, you get
3W * W <= 112
evaluate
3W^2 <= 112
3W <=
W <=
cm
Your answer is y=15 for your problem
Create equations using the given information
1) x+y=56
2) y=x-16
Substitute the value of y into the 1st equation and simplify
1)x+x-16=56
2x=72
x=36
Substitute the value of x into the 1st equation and simplify
1)x+y=56
36+y=56
y=20
Answer: 20 and 36
Answer:
4/9 is bigger
Step-by-step explanation:
For the 1st fraction, since 9 × 4 = 36,
4/9 = 4 × 4
9 × 4 = 16/36
Likewise, for the 2nd fraction, since 36 × 1 = 36,
7/36= 7 × 1
36 × 1 = 7/36
Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction
16/36> 7/36 or 4/9 > 7/36
Answer:
a. 12 years
b. 30 years
Step-by-step explanation:
a) Assume Liaqat's age is x. His age would be:
5x + 10 = 70
5x = 70- 10
x = (70 - 10) / 5
x = 12
<em>Liaqat is 12 years old.</em>
b. Assume his uncle's age is y;
4y - 10 = 130
4y = 130 - 10
y = (130 - 10) / 4
y = 30
<em>Liaqat's uncle is 30 years old. </em>
