The correct answer is B. x is greater than -2.
Make an equation system based on the problem
eg. a is the first number and b is the seond number
An equation for "<span>The sum of two numbers is 53" is
</span>⇒ a + b = 53
An equation for "<span>twice the first number minus three times the second number is 26"
</span>⇒ 2a - 3b = 26
<span>
Solve the equations by elimination and subtitution method
Eliminate a to find the value of b
a + b = 53 (multiplied by 2)
2a - 3b = 26
--------------------------------------
2a + 2b = 106
2a - 3b = 26
------------------- - (substract)
5b = 80
b = 80/5
b = 16
Subtitute the value of b to one of the equations
a + b = 53
a + 16 = 53
a = 53 - 16
a = 37
The numbers are 16 and 37</span>
Answer:
Option A
Step-by-step explanation:
since V = p×r^2×h
r = 3/2
hence, option a is correct.
Answer:
Option B, 8/5 hr
Step-by-step explanation:
1/2 + 1/8
1*4 / 2*4 + 1/8
4/8 + 1/8
5/8 = 1/t
5t / 5 = 8 / 5
t = 8/5
Answer: Option B, 8/5 hr
To find the unit rate you would need to find the cost per ounce of potato chips. To find this you would simply divide. $3.80/20 = .19
So the unit rate in your question is $0.19
Hope this helps! :)
