Answer:
A
Step-by-step explanation:
trust
Perimeter means the sides add up to 12.
Rectangles have two pairs of equal sides.
2(one side) + 2(another side) = 12
2 (one side + another side) = 12
(one side + another side) = 6
To draw a rectangle with a perimeter of 12 units, the two adjacent sides must add up to 6.
1 + 5
2 + 4
3 + 3
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
