the
complete question in the attached figure
Part A
we know
price poster boards----------- > $0.75
let
p------------- > number of poster boards
q------------- > money spends on poster boards----------> $2.25
q=p*0.75---------> p=q/0.75=2.25/0.75=3
the answer part A is 3
Part B
Let
x-------------- >number of paint brushes------------ > $0.95
y-------------- >number of jar of paint ------------ > $0.99
we know
0.95x+0.99y=4.87
using a graph tool
see the attached figure
the solution is the line shown in the graph
the solution must be a pair of whole numbers, <span>the only pair that meets that condition is the point (2,3)
x=2-------------- ></span>number of paint brushes
y=3-------------- >number of jar of paint
Answer: positive: up down/ up up negative: down up down down
Step-by-step explanation:
The usual definition of Least Common Multiple of two numbers states that is the Least positive integer that can be evenly divided by both numbers. The way it is usually defined the two numbers must be positive integers
Amount spent on coffee= $70 - $48.31 = $21.69
Coffee cost $7.23 per pound
No of pounds of coffee bought = Amount in $ / Cost in $ per pound
= 21.69 / 7.23
= 3
3 pounds of coffee was bought
To solve this, you must rearrange the variables in the given equation. Since we are looking for h, we want the equation to be h = something. You must divide both sides by 1/3 lw. When dividing like this, you must use the KCF (Keep, Change, Flip) method. Keep the first part (v), change the sign from division to multiplication, and flip the fraction. This means that the fraction becomes 3/1 lw. When that is multiplied by v, it makes the equation h = 3v/lw. That is your final answer -> h = 3v/lw.
