t = -2.5 or -\frac{5}{2}

Here's how we find that out:

2t -5 = -10..........................We need to get the variable, t, by itself

2t = -5................................Add 5 to both sides

t = -2.5...............................Divide both sides by 2

So, your answer is - \frac{5}{2} 0r -2.5

I hope this helped! Have a great day! :))

Apples are sold in bags of four that cost $5, or bags of six that costs $7 per bag. What is the smallest cost at which you can b
babunello [35]
STEP 1:
BAGS OF FOUR
find number of bags needed to total 74 apples

= 74 ÷ 4 apples/bag
= 18.5 bags

*must round up to 19 bags because we cannot buy a partial bag

STEP 2:
BAGS OF FOUR
calculate price of 19 bags of 4 apples per bag

= 19 bags * $5/bag
= $95 for 19 bags of 4 apples/bag

STEP 3:
BAGS OF SIX
find number of bags needed to total 74 apples

= 74 ÷ 6 apples per bag
= 12.3333 bags needed

*must round up to 13 bags because we cannot buy a partial bag

STEP 4:
BAGS OF SIX

calculate price of 13 bags of 6 apples per bag

= 13 bags * $7 per bag
= $91 for 13 bags of 6 apples/bag


ANSWER: The smallest cost to buy 74 apples is $91.

Hope this helps! :)

Which of the following is the surface area of the right cylinder below?
Evgen [1.6K]
The formula for the surface area of a right cylinder is 2πrh + 2πr^2. r is the radius, and h is the height.


In this instance, the radius is 4, so plug that in for r. (I.E. Replace r with 4).


The formula is now 2π4h + 2π4^2.


Next, plug in the height, 8 for h.



Now we have 2π4(8) + 2π4^2, which is approximately 301.59.


The surface area is 301.59. (Unit of measure was not specified)
