3x - 10x = 14
-7x = 14
x = -2
Step-by-step explanation:
So, assuming that x would be the number of miles towed, this word problem gives us two linear equations:
One for Brook's Body Shop, which is y = 3x + 25
And one for Morgan Motors, which is y = 5x
We see that these two lines intersect at the point (12.5, 62.5). Remember that the x-value stands for the number of miles. So, at 12.5 miles, both companies charge the same rate.
This means that Morgan Motors is cheaper for any number of miles less than 12.5. In contrast, Brook's Body Shop is cheaper for any number of miles more than 12.5.
In conclusion, if you had to be towed less than 12.5 miles, you should go to Morgan Motors because they are cheaper for short distances. If you had to be towed more than 12.5 miles, you should go to Brook's Body Shop because they are cheaper for longer distances.
Answer:
(c) 330
Step-by-step explanation:
least common factor of 180 and 594 is 5940.
greatest common factor of 180 and 594 is 18.
so, the ratio of the least common factor to the greatest common factor will be;
ratio = 
= 330
11) 2x+6y-3; x=5,y=4
the question is asking to evaluate for y when x=5 and evaluate for x when y=4,
2x+6y-3
2x+6y=3
2(5)+6y=3
10+6y=3
6y=3-10
y=-7/6 when x=5
2x+6(4)=3
2x+24=3
2x=3-24
x=-21/2 when y=4
12)
Input Output
N 4(n+3)
12 4(12+3) = 4(15)=60
14 4(14+3)=4(17)=68
18 4(18+3)=4(21)=84
25 4(25+3)=4(28)=112
13)8x+y-10; x=4, y=50
8x+y=10
8(4)+y=10
32+y=10
y=10-32
y=-22 when x=4
8x+50=10
8x=10-50
8x=-40
x=-40/8
×=-5/1=-5 when y=50
14) b is correct
