Answer:
B. 4.5 mi.
Step-by-step explanation:
Let g = length of green route
b = length of blue route
(1) 6g + 5b = 52 (2) 12g + 13b = 119
Mult. (1) by -2 <u> -12g - 10b = -104</u>
<u> </u> 3b = 15
b = 5
6g + 5(5) = 52
6g + 25 = 52
6g = 27
g = 27/6 = 9/2
Where's the graph at? Did you forget to place?
X = -6.4
First, you would subtract 8 on both sides:
-2.5x + 8 - 8 = 24 - 8
The 8 cancels out on the left side of the equation, and 24 - 8 = 16
Next, divide both sides by -2.5, to get rid of the number that is multiplying by x.
-2.5x/-2.5 = 16/-2.5
= x = -6.4
*Remeber, when dividing a negative by a positive, the answer is negative. In this case, 6.4 is negative.
Answer:
11
Step-by-step explanation:
You have to first make the 7 into a fraction (7/1) then keep, change, flip.
You keep the 7/1 as it is, you change the division sign into a multiplication sign, and you flip the 7/11 to 11/7. You then just multiply straight across to get 77/7 which is the same thing as 11/1 which is the same thing as 11!
Final answer:11
