Answer:</h2>
By Substitution Method
<h2>
Step-by-step explanation:</h2>
Solve by Substitution :
We have two equations
y = 5x ---------------> Equation 1
y = 2x - 15 ------------> Equation 2
y= 2x - 15 and y= 5x
So Put the value of y in Equ 2
(5x) - 2x = -15
3x = -15
Solve equation [1] for the variable x
3x = - 15
x = - 5
Now
y = 5x
x = -5
Use the x value to solve for y
y = 5(-5) = -25
Solution :
{y,x} = {-25,-5}
So y= -25 and x= -5
Hey there!
ASSUMING:
2k^3 + j
CONVERTING
= 2(-2)^3 + (-5)
= 2(-2)^3 - 5
= 2(-2^3) - 5
= 2(-1 * 2 * 2 * 2) - 5
= 2(-2 * 4) - 5
= 2(-8) - 5
= -16 - 5
= -21
Therefore, the answer should be: -21
Good luck on your assignment & enjoy your day!

Answer: 9/12 ÷ 3/12 is 3.
Step-by-step explanation: Do the KFC.
K. Keep.
F. Flip the second term to 12/3.
C. Change the ÷ into ×. Then, solve.
9 x 12 is 108, and 3 x 12 is 36.
108 ÷ 36 = 3.
A. d = 55(t + 0.5)
Explanation:
distance = rate x time or d = rt
rate = 55 mph
time = t + 0.5
d = 55(t + 0.5)
Answer:
90 minutes
Step-by-step explanation:
42 min is to 70 km what x is to 150 km
42/70 = x/150 (cross multiply)
(42 * 150) / 70 = 90
