A. 7(−10)
B. −7(−10)
C. 7÷10

Phillp and Arnold are helping their teacher buy supplies for a research project.
The teacher gave Phillip $39.00 to buy pencils from the school store. The pencils come in boxes of 12 and cost $1.95 per box.
Arnold was given $48.00 to buy index cards at an office supply store. Index cards are sold in packs of 200 cards and cost $4.80 per pack.
Each student will receive a bag containing three pencils and 25 index cards. How much will each bag cost?
Part A. Create an equation to model how many boxes of pencils Phillip can purchase. Solve the equation. (5 points)
Part B: How many pencils was Phillip able to purchase? (5 points)
Part C: Create an equation to model how many packs of note cards Arnold can purchase. Solve the equation. (5 points)
Part D: How many note cards was Arnold able to purchase? (5 points)
Part E. In a complete sentence, answer how many bags of 3 pencils and 25 note cards can Arnold and Phillip create (5 points).
Answers
Answer: Part A
20 boxes of pencils
Part B
240 pencils
Part C
10 boxes of note cards
Part D
2,000
Part E
80 bags
Step-by-step explanation:
Part A
Divide 39.00 by 1.95 and you should get your answer
Part B
take the answer you got from part a and multiply it by the number of pencils that are in the box
Part C
take 48.00 and divide it by 4.80 and you should get your answer
Part D
take your answer from Part C and multiply it by how many card are in a box and you should get your answer
Part E
divide the amount of pencils by three and it gives you 80 and for the cards do the same but take the amount of cards and divide it by 25 and it gives you 80 so the amount is 80 bags.

[tex]\huge\boxed{l = \frac{p}{2} - 2}[/tex]
Step-by-step explanation:
If we have the equation [tex]p=2(l+w)[/tex] and we want to solve for l, our goal is to isolate l on one side of the equation.
We can do this by reversing the equation - looking at what is stopping l from being alone on one side.
First lets divide both sides by 2:
[tex]p \div 2 = 2(l+w) \div 2\\\frac{p}{2}=l+w[/tex]
Now we can subtract w from both sides.
[tex]\frac{p}{2} - w = l+w-w\\\\\frac{p}{2} - w = l[/tex]

A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4°F. The submarine dives down 115 feet deeper, and the water temperature drops by 2 1/5 °F. What were the elevation and the water temperature after the submarine dove? Assume that sea level is at 0 feet of elevation.
Write an expression to represent the water temperature after the submarine’s final dive. Then simplify the expression to find the temperature.
Answers
Answer:
At the elevation 617.5 feet below the sea level temperature of the water was 61\frac{1}{20}°F
Step-by-step explanation:
At 502.5 feet below the sea level temperature of the water is 63\frac{1}{4}°F
When submarine dives down 115 feet deeper, water temperature drops by 2\frac{1}{5}°F
Elevation after the submarine dove = -502.5 - 115 = -617.5 feet
This negative sign represents the elevation below the sea level.
And the temperature will be = 63\frac{1}{4}-2\frac{1}{5}
= \frac{253}{4}-\frac{11}{5}
= \frac{1265-44}{20}
= \frac{1221}{20}
= 61\frac{1}{20}°F
Therefore, at the elevation 617.5 feet below the sea level temperature of the water was 61\frac{1}{20}°F
The required expression is y = 0.01x + 58.2. Where, x = level of sea and y = temperature. At 115 feet deeper temperature is 61 1/4°F.
A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4°F.
It is the relationship between sets of values. e g y=f(x),
Here, assume that relation ship between temperature and sea level is linear. So the expression can be calculated as y = - 0.01x + 58.2.
Since at 115 feet deeper from 502.5 temperature-
total sea level; = 502.5+115
= 617.5
Put it in expression
y = -0.01 * 617.5 + 68.2
y = 61.25
y = 61 1/4 °F
Thus, the required expression is y = 0.01x + 58.2. Where, x = level of sea and y = temperature. At 115 feet deeper temperature is 61 1/4°F.

Answers
Answer:
When multiplying the same base raised to an exponent, keep the base and add the exponents.
Step-by-step explanation:
The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. In this example, you can see how it works. Adding the exponents is just a short cut! The "power rule" tells us that to raise a power to a power, just multiply the exponents.
