Answer:
b. 4x = 48
Step-by-step explanation:
If you look closely an multiply 4 x 8, it equals 32, not 48
The other equations:
8 x 8 does equal 64
10 x 8 does equal 80
9 x 8 does equal 72
It's pretty simple once you try each problem first
Hope this helps!
Answer:
7/5 + b/5 - 4m
Step-by-step explanation:
(1/5)(7 + b) - (4)(m) = 7/5 + b/5 - 4m

1/√3= 5/z
z= 5√3
Answer:
0,1.5
Step-by-step explanation:
y = 510 - 60x
We want to find the domain or the x values where x represents the time
We need to determine the possible values for x
Y cannot be greater than 510 or less than 0. 510 means they have not started the trip, and 0 means they have arrived
510 = 510 -60x
Subtract 510 from each side
510-510 = 60x
0 = 60x
The smallest value of x can be 0
0 = 510 - 60x
Subtract 510 from each side
-510 = 510-510-60x
-510=-60x
Divide by -60
-510/-60 = -60x/-60
8.5 = x
The maximum value of x is 8.5 hours
So x must be between 0 and 8.5 inclusive.
X2 + x1 divided by 2. then y2 +y1 divided by 2. = midpoint, I think.
