-140 = 28 + 4(5y-2)
Use distributive property:
-140 = 28 + 20y -8
Combine like terms:
-140 = 20 + 20y
Subtract 20 from both sides:
-160 = 20y
Divide both sides by 20:
y = -160 / 20
y = -8
The answer is B) -8
So begin by doing 360-284=76
90+76=166
180-166=14
X=14
It is given that batteries come in a packs of 4. It means in each pack there are 4 batteries.
Joe used 58 batteries . So to find the total number of packets of batteries joe has to open is
Number of batteries used / Total number of batteries in each packet
= 58 / 4
= 14.5
The number of battery can not be in decimal. So we will round the answer to integer. If we round it to 14 it means 14 packets. But in 14 packets there are 14*4 = 56 batteries .
But we know that Joe used 58 batteries. So we will round the final answer to 15.
It means Joe has to open 15 packets of batteries.
Average rate of change means find the slope of the secant line. So if there is a function f(x) and you want to find the average R.O.C over the interval [a,b], it would be (f(b)-f(a))/(b-a)
1. (f(3)-f(1))/(3-1)= (0-(-2))/2= 1, so D.
2. Same concept; (8-4)/(3-1)=2, so A.
3. Again, (39-(-1))/5= 8, B.
Answer:
24
Step-by-step explanation:
a square has 4 sides, which in this case are 6 feet long. to get the area you have to multiply the two numbers, which is 6 times 4.
