Step-by-step explanation:
Keep in mind you would need a total of 120 ounces.
A: Corn cereal comes in 12 oz boxes and the person used 5 boxes, thus taking 60 oz away from the total, leaving 60 oz. Next, you’d have to divide 60 oz by 4 (since that’s how many boxes of wheat cereal were used). Resulting in a wheat box being worth 15 ounces!!
B: 12c+ 15w= 120 (c= corn cereal, w= wheat cereal)
C: 5 boxes of corn cereal with 4 boxes of wheat cereal; 0 boxes of corn cereal with 8 boxes of wheat cereal; 10 boxes of corn cereal with 0 boxes of wheat cereal.
Answer:
Step-by-step explanation:
A quick review on PEMDAS, the order of how to solve an equation:
P - parentheses. When parentheses are being used, you have to do everything inside them before doing everything outside of them.
E - exponents. We'll skip these, since there aren't any exponents we need to worry about in this equation.
M/D - multiplication/division. I include these both together because they can be done at the same time.
A/S = addition/subtraction. Can also be done at the same time.
Some other things to note:
You add all the things with an x attached to it, and you add all the things without an x attached to it, and these never cross.
When you bring something from one side of an equal sign to another, you make it negative.
Let's solve for x using what we've learned:
Answer:
p ≤ 8
Step-by-step explanation:
Given the following :
Maximum weight elevator can hold ≤ 1800
Weight of delivery person and packages = 520 pounds
Average weight of a person = 160 pounds
Inequality to show how many additional people elevator can hold?
(weight of delivery person and packages + average weight of persons * number of persons) ≤ 1800
Let p = number of persons
(520 + 160p) ≤ 1800
160p ≤ 1800 - 520
160p ≤ 1280
p ≤ 1280 / 160
p ≤ 8
The first step you should do is subtract 32 from both sides so your answer will turn out like this -
F = (9/5) C + 32
-
F - 32 = (9/5)
Then we will multiply both sides by 5.
5 ( F - 32 ) = 9 C
Divide both sides by 9 to isolate C.
(5/9) ( F - 32 ) = C
So the answer is :
C = (5/9) ( F - 32 )
Hope this helps :)
