Answer:
B) 4 square root 80^x
Step-by-step explanation:
Answer:
y=5/2x+2
Step-by-step explanation:
rearrage equation: y=5/2x-7
new slope is same: y=5/2x+b
substitue point (-2,-3):
-3=5/2(-2)+b
-3=-5+b
-3+5=b
2=b
Answer: 18080!
Step-by-step explanation:400 x 450
1. Multiplying from the oneths place ( turning 45.2 into 450)
2x0=0 2x0=0 2x4=8 = So the first answer is 800
2. Multiply from the tenths place
5 x 0 = 0 5 x 0 = 0 5 x 4 = 20 = the second answer is 2000
Multiplying the hundredths place
4 x 0 = 0 4 x 0 = 0 4 x 4 = 16 = The third answer is 1600
800 + 2000 + 1600 = 18080 Hope this helped! :)

Step-by-step explanation:
Answer:
B: 8 7/8 Lbs
Step-by-step explanation:
answer = 
step 1 find a common denominator
common denominator - 8
* apply *

now we have

step 2 make each fraction a improper fraction
We can do this my multiplying the big number by the denominator and adding that to the numerator.

now we have

Now we can subtract
remember when subtracting fractions you only subtract the numerators. ( so we keep the denominator as 8 )
so 121 - 28 - 22 = 71
so the answer is 
finally we want to change the answer back into a mixed fraction
To do this we divided 71 and 8
8 can go into 71 8 times
8 * 8 = 64
71 - 64 = 7
We're left with
