The best way to solve this is to write it out part by part.
The first part is "the sum of 8 and 3," which is (8+3)
The second part is "...times a number," so we have n(8+3)
Lastly, "...is 23," means n(8+3) = 23, so here's the equation. In order to solve for n, divide both sides by (8+3) so 23/(8+3) which is 23/11. So the "number" is 23/11.
4x + 2x + 2
= 6x + 2
So the answer is B
7.5x - 100 > 79.86 + 5.8x
7.5x - 5.8x > 79.86 + 100
1.7x > 179.86
x > 179.86 / 1.7
x > 105.8
Answer:
Each ticket costs $9.55
Step-by-step explanation:
You divide 57.30 by the number of tickets(6).
57.30/6 = 9.55
Answer:
y= -x-3
Step-by-step explanation:
A line is parallel to another line if their slope is the same. In this case the slope is -1 (-x is basically -1x). So far we have y=-x+b (We dont know what b is yet). next we can insert the coordinate back into the equation y=-x+b where 1 is the y and -4 is the x.
We get...
y= -x+b
1= -(-4)+b
1=4+b
b=-3
Our final equation is y=-x-3
Hope this helped
