Answer:
Step-by-step explanation:
(-6,8)...x = -6 and y = 8
lets start subbing
5x + 3y = -6
5(-6) + 3(8) = -6
-30 + 24 = -6
-6 = -6
so (-6,8) IS a solution to this equation
2x + y = -4
2(-6) + 8 = -4
-12 + 8 = -4
-4 = -4
so (-6,8) IS a solution to this equation
A. It is the only solution to the system
Answer:
C
Step-by-step explanation:
97.62+22.95+14.78=135.35
135.35*.07
9.4745
Rounded to 9.47
Answer:
Step-by-step explanation:
<u>As per question we have:</u>
- p > 0, q > 0
- 31p/8q ≤ 5 ⇒ 31p ≤ 40q
Since 31 and 40 have no common factors, the minimum values of p and q are 40 and 31 respectively.
<u>So the minimum value of p + q is:</u>
Answer:
C). 54 cm.
Step-by-step explanation:
I think you mean a rectangle .
If the length is x then the width = 0.75x (because 3/4 = 0.75).
Perimeter = 2*length + 2*width.
252 = 2x + 2*0.75x
252 = 2x + 1.5x
252 = 3.5x
x = 252 / 3.5
= 72 which is the length,
The width = 3/4 * 72
= 54 cm.
