Answer:
2x + 4.8y +13.2
Step-by-step explanation:
1. (4)(0.5x+2.5y+−0.7+−1.3y+4)
2. (4)(0.5x)+(4)(2.5y)+(4)(−0.7)+(4)(−1.3y)+(4)(4)
3. 2x+10y−2.8−5.2y+16
4. 2x + 4.8y +13.2
I hope this helped, please mark Brainliest, thank you!!
First,, you need to simplify the radical in the first parenthesis.
(6) × (3)
Now simplify the radical in the second parenthesis.
(6) × (12)
Then remove the parenthesis.
6 × 12
Now calculate the product to find your answer.
72
This means that the correct answer to your question is going to be 72.

Answer:
True
Step-by-step explanation:
Answer:
<em>Tom must score 95 on his last test</em> to have an average of 92.
Step-by-step explanation:
Tom's average score (92) = the sum of all his five grades/the number of grades (5)
Given that A is the grade Tom must receive on his last test, we have the equation as follows:
92 = (89+94+86+96+A)/5
<=> A = 92 × 5 - (89+94+86+96)
=> A = 95
