<span>y=(x/3)−8
hope this helps pls mark me as brainliest</span>
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:
x=9, x=-9
Step-by-step explanation:
subtract 3 from both sides
x^2=81
then squareroot both sides (remember that there is a positive and negative solution!)
x=9, x=-9
Answer: 10
Step-by-step explanation:you say they are equal (seems right )
Since this is a quadrilateral, all angles together = 360°. The angle that is 128° is congruent to angle y, so y=128°. Angle x and y are supplementary, meaning together they equal 180°, or x+y=180°. So x=180°-y. Which means, x=180°-128°=52°.
