315/5 = x/9....315 miles to 5 hrs = x miles to 9 hrs
cross multiply
(5)(x) = (315)(9)
5x = 2835
x = 2835/5
x = 567
He will drive 567 miles in 9 hrs
Start off by combining like terms on the LHS (the terms with x in them).
So we get
Replacing this result with what we had before on the LHS, we get
⇒Solve for x (divide both sides
)
⇒Don't forget about reciprocity rules when dividing. This is the same as multiplying both sides by
⇒
⇒
***This is a proper fraction
It is a rectangle and parallelogram.
It is is parallelogram because opposite sides are congruent.
Step-by-step explanation:
20 kg at N5.00 each = N100.00
10 kg at N3.00 each = N30.00
5 kg at N2.00 each = N10.00
5 kg at 50k each = N2.50
Total = N 142.50.
(b) Selling price = N142.50
Cost price = N120.00
∴ Profit = N(142.50 - 120.00) = N22.50.
