So u will do 88+84=172+88=260+91=351 and that is all four tests added up now u have to divide the answer by 4 because it was four tests averages
351/4=87.75 wich is aproxamately 88
so with all four of them added wich is 351 u will add the answer choices so 351+96=447/5=89.4 wich is aproxamately 89
351+97=448/5=89.6 wich is aproxamately 90
351+98=449/5=89.8 wich is aproxamately 90
351+99=450/5=90
so i would say that 99 points is the one she needs to score because it isnt asking for aproxamately
so it is 99 points
Answer:
1. -2 = x
2. 19 = x
3. -22 = b
4. 30 = y
5. -5 = t
Step-by-step explanation:
1. -3x = 6 [-1 to the right side of the equivalence symbol]
2. 5x = 95 [23 to the right side of the equivalence symbol]
3. ᵇ/₂ = -11 [23 to the left side of the equivalence symbol]
4. ⅓y = 10 [7 to the right side of the equivalence symbol]
5. -2t = 10 [13 to the right side of the equivalence symbol]

To solve this problem, you need to divide the total number of students going on the field trips with the number of students in each group.
44/7
= 6 R 2
Since, I assume there can <em>only</em> be groups of 7, the answer is 6.
Answer:
Part A number 2 (see work below)
<em>*please give me brainliest lol*</em>
Step-by-step explanation:
(8r^3 + 2r^2 + 1) - (7 - 7r^3 + 3r^2)
<em>after factoring out the negative, you'll have:</em>
8r^3 + 2r^2 + 1 -7 + 7r^3 - 3r^2
<em>now we combine like terms, and your answer is:</em>
15r^3 - r^2 - 6
