Answer:
Chad had 15 dollars left for gift C.
Step-by-step explanation:
Given:
Chad had total amount = 30 dollars.
Amount spend on gift A = 9 dollars.
Amount spend on gift B = 6 dollars.
To Find:
Amount Left for gift C = ?
Solution:
Total Amount = 30 dollars.
Total number of gifts = 3 i .e Gift A, Gift B , Gift C.
Total amount spend for Gift A and Gift B = Amount spend on gift A + Amount spend on gift B
∴ Total amount spend for Gift A and Gift B = 9 + 6
∴ Total amount spend for Gift A and Gift B = 15 dollars.
Now,
Amount Left for Gift C = Total Amount - Total amount spend for Gift A and Gift B.
∴ Amount Left for Gift C = 30 - 15
∴ Amount Left for Gift C = 15 dollars

Answer: Plan A will cost less than Plan B for phone use that is less than or equal to 100 minutes
Step-by-step explanation:
Let m be the number of minutes of phone use.
We can convert $35 and $36 to 3500 cents and 3600 cents respectively.
Then, in Plan A, it would cost 3500 + 6m and in Plan B, it would cost 3600 + 5m.
Since we want Plan A to cost less, we can set up an inequality saying:

We can subtract 3500 + 5m from both sides:

Therefore, Plan A will cost less than Plan B for phone use that is less than or equal to 100 minutes.
Answer: SIMPLIFY TERMS === 32X^3-12X^2+51X=35
Step-by-step explanation:
(4x2+x+7)(8x−5)
Expand (4x2+x+7)(8x−5)
by multiplying each term in the first expression by each term in the second expression.
4x2(8x)+4x2⋅−5+(x(8x)+x⋅−5)+(7(8x)+7⋅−5)
Simplify terms.
