Solve the system of equations.
12x + 3y = 12
-6x +y = -26
A) (-3,9)
B (-6, -9)
© (-3,8)
D (3, -8)
12x + 3y = 12
2(-6x +y = -26)
12x + 3y = 12
-12x + 2y = -52
—-now x cancels out
5y/5 = -40/5
y = -8
The answer should be D. Let me know if you got it right.
Answer:
D). 
Step-by-step explanation:
For better clarity let us re write the options
A).
B).
C).
D).
To express polynomial with mixed variables in standard form, we begin by the highest coefficient of x to the smallest (we place high precedence on the coefficient x terms)
14/38 simplified would be 7/19
Answer:
It travel at the rate of <u>500 miles per hour</u>.
Step-by-step explanation:
Given:
Ewans flight is scheduled to travel 1,750 miles in 3.5 hours.
Now, to find the rate it travel per hour.
Distance = 1,750 miles.
Time = 3.5 hours.
So, to get the rate we put formula:



Therefore, it travel at the rate of 500 miles per hour.
To find the average of numbers you have to add all the numbers and divide by the number of numbers. *confusing*
25 + 25.4 + 25.35 + 26.1 = 101.85
101.85 ÷ 4 = 25.4625
