Y= 4x-1
If y is 1, then plug 1 in the equation,
1= 4x-1
Add 1 on both sides,
2= 4x
Divide by 4 on both sides,
x= 4/2
Reduce 4/2 to 1/2
Therefore, x= 1/2
At a wholesale club, the shampoo costs $2.35 each. At a drugstore, the shampoo costs $2.25 each. $14.10 divided by 6 is $2.35 and $4.50 divided by 2 is $2.25.
Answer:
2940
Step-by-step explanation:
Surface Area of a rectangular prism is 2(LW)+2(HW)+2(LH)
We have that the surface area is 1414 where L=c , H=20, W=7
Let's plug all of this in to solve for c:
2(LW)+2(HW)+2(LH)=1414
2(c*7)+2(20*7)+2(c*20)=1414
14c+280+40c=1414
54c+280=1414
54c=1414-280
54c=1134
c=1134/54
c=21
Now the volume of a rectangular prism is V=L*W*H
So plug in our values L=21, H=20, W=7
V=21*20*7=2940
Answer:
6 sets
Step-by-step explanation:
1/9=0.11 rounded
1/3=0.33 rounded
6.11x3=18.33
3.33x3=9.99
18.33+9.99=28.32
Answer:
42.9m
Step-by-step explanation:
The topic is on similar triangle
you are comparing triangle MNP with triangle MAB
side AB is similar to NP
side MA is similar to MN
side MB is similar to MP
now MA = MN - AN
= 67.2 - 32
= 35.2m
MA/MN = MB/MP
35.2/67.2 = x/81.9
cross multiply and solve
x = 42.9m
