Hello,
Let's
V1 the velocity of the 1st bricklayer,
V2 the velocity of the 2nd bricklayer,
1wall=V1*6==>V1=w/6
1wall=V2*4==>V2=w/4
==>V1+V2=w/6+w/4=10w*24=5w/12
Let's t the time for the 2 bricklayer to build the wall
(V1+V2)t=w
==>5w/12*t=w
==>t=12/5 (h)=2h24min.
Answer: It’s C
Step-by-step explanation: It is easiest to change what wants you want to spend your money on. It is hard to ask for a raise or income change. And spending on needs might not change, same goes for savings.
Answer:
D. 16
Step-by-step explanation:
GE = 9 + x - 2 = 9 + 9 - 2 = 18 - 2
GE = 16
Plug in “0” for y, rearrange and solve.
Remember when you want to find the intercept of a variable, you plug in 0 for the opposite variable. Same goes for finding the x intercept.
When you want to find…
Y intercept: X=0
X intercept: Y=0
Answers:
X int= -6 or (-6,0)
Y int=2 or (0,2)
