Answer:
x = 16
Explanations:
The given rquation is:
Step 1: Cross multiply the equations. That is 28 multiplies 4 and 7 multiplies x:
112 = 7x
Step 2: Divide both sides by 7
16 = x x = 16
Answer:
1.36
1. Find the mean of all values. (3)
2. Find the distance of each value from that mean (subtract the mean from each value, ignore minus signs)
3. Find the mean of those distances.
17.99 + 0.83m = 140
0.83m = 140 - 17.99
0.83m = 122.01
m = 122.01 / 0.83
m = 147 <== Mike drove 147 miles
Ax+b=y
put the both values the left one is x and the right one is y
(1,3)=> a+b=3
(2,1)=> 2a+b=1
subtract both of the equations you will get -a=2
so a=-2 and put a in any of the equation you will get b is 5 so the equation is -2x+5=y
the slope is the x’s number so it’s -2
