...................................................
Answer:
A
Step-by-step explanation:
x + y = 4a + 7
x - y = 2a + 5
In both equations, make x the subject of the formula
x = 4a + 7 - y equation 1
x = 2a + 5 + y equation 2
Subtract equation 2 from equation 1
2a + 2 -2y
= 2a + 2
Answer:
5/7
Step-by-step explanation:
We have two points ( 2,-2) and (9,3)
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 3- -2)/( 9-2)
= ( 3+2)/(9-3)
= 5/7
The answer for this is D.
Answer:
Center a processes it faster
Step-by-step explanation:
Center B math: 2 tons as pounds is 4000 pounds.
4000/7=571.43 pounds a day
571.43/24=23.81 pounds a hour
23.81 pounds per hour is less than 100 pounds an hour. so center a is the faster one.
