Answer: 80%
Step-by-step explanation:
To find the average, add all the grades and divide by the number of grades
sum of all grades/number of grades
85 + 100 + 88 + 80 + 95 + x/6
She wants to have an 88, so we can set the expression above equal to 88
448 + x/6= 88
Multiply by 6 on both sides
448 + x = 528
Subtract 448 on both sides
x=80
She needs to score at least an 80 to get an 88 average.

1.5 Acres 2 Acres
42.5 ( 1.5 ) + 15 = 78.75 | 42.5 ( 2 ) + 15 = 100
78.5 ( 1.5 ) + 5 = 122.75 | 78.5 ( 2 ) + 5 = 162
Answer:
The first one
Step-by-step explanation:
Answer:
number 10
dy/dx =(dy/dt).(dt/dx)
now find
dy/dt=4t-1. , dt/dx=1
so : dy/dx=(4t-1).(1)
dy/dx= 4t-1 ,we have x=t-3-----> t=x+3
subtitute at t
dy/dx= 4(x+3)-1=4x+12-1= 4x+11
