Answer:
- FALSE
- TRUE
- TRUE
Step-by-step explanation:
<u>1.</u>
- Non-standard units can be used to measure volume
- Examples : m³, in³, cm³, mm³, L
<u>2.</u>
- The volume of a rectangular prism can be found by multiplying the length, width, and height
- <u>V = lwh</u>
<u />
<u>3.</u>
- If there are smaller units, then naturally more of the units will be used
- If there are larger units, then less of the units will be used
Hey user☺☺
The graph will have no solution.
Hope it works
Going upstream: 432 km / 6 hours = 72 km/h
Going downstream: 384 km / 4 hours = 96 km/h
Going upstream against the current means that the effective speed is:
r_boat - r_current = 72
Meanwhile, going downstream with the current means;
r_boat + r_current = 96
Adding both equations (to cancel out r_current) gives:
2r_boat = 72 + 96
r_boat = 84 km/h
Substituting back into one of the original equations: r_current = 12 km/h.
Answer:
25
Step-by-step explanation:
We need to set up a system of equations, then solve for the number of board markers.
Let r represent red pens, let b represent board markers.
She has 41 items, so our first equation is r+b=41.
The total cost is $46.30, so our second equation is .55r+1.5b=46.3.
r+b=41
.55r+1.5b=46.3
Let's use substitution.
r+b=41
r=41-b
.55r+1.5b=46.3
.55(41-b)+1.5b=46.3
22.55-.55b+1.5b=46.3
22.55+.95b=46.3
.95b=23.75
b=25
He bought 25 board markers.
Answer:
y=
x-6.5
Step-by-step explanation:
= 
= 
y=mx+b
-8 = () (-6) +b
-8 = - 
+b
b= -6.5
