Answer:
b= (Z-m-z)/(x)
Step-by-step explanation:
Z-m=z+bx
Z-m-z=bx [Transpose z of R.H.S to L.H.S] / [Substract z from L.H.S and R.H.S]
(Z-m-z)/(x)=b [Divide by x on both sides i.e, L.H.S and R.H.S]
b= (Z-m-z)/(x)
Hope this helps you.
Answer:
33
Step-by-step explanation:
2x^2 +3y
Let x =3 and y=5
2 *(3)^2 +3(5)
We do exponents first
2 * 9 + 3(5)
Then multiply
18+ 15
Add
33
Answer:
560 ft/min
Step-by-step explanation:
Let r represent Samantha's running rate in feet per minute. Then r-230 is her walking rate. We can use the relation ...
distance = speed × time
to write an equation for the total distance Samantha went.
20r + 15(r -230) = 16150
35r - 3450 = 16150 . . . . eliminate parentheses, collect terms
35r = 19600 . . . . . . . . . . add 3450
r = 560 . . . . . . . . . . . . . . divide by the coefficient of r
Samantha ran 560 feet per minute.
