1. Sarah and Maya both need notebooks and pencils. The equation that represents Sarah's
purchases is y = 13- 3x. The equation that represents Maya's purchases is y = 7 -x. If y
represents the price of notebooks, and x represents the price of pencils, what are the prices of
the notebooks and pencils?
a) pencils: $4 notebook: $3 go to card 4
b) pencils: $6 notebook: $1 go to card 3
c) pencils: $3 notebook: $4 go to card 5
d) pencils: $1 notebook: $6 go to card 7
e) pencils: $4 notebook: $4 go to card 2
Step-by-step explanation:
We have y = 13 - 3x and y = 7 - x.
=> 13 - 3x = 7 - x
=> 2x = 6, x = 3.
Then y = 7 - (3), y = 4.
Hence the price of a pencil is $3 and the price of a notebook is $4. (C)
answer is c) pencils: $3 notebook: $4 go to card 5

solve for x in the following question 2x - 3 = 1
Answer:
x = 2
Step-by-step explanation:
2x-3 = 1
use addition property of equality (add 3 to each side to keep balance)
2x = 4
use division property of equality (divide both sides by 2)
4/2 = 2
so,
x = 2

Find the x- and y-intercepts of the graph of the linear equation 3x+6y=2.
Answer:
x intercepts(8,0)
y intercepts (0,-4)
Answer:
x=2/3 y=1/3
Step-by-step explanation:
3x+6y=2 get rid of 6y and put down 3x=2
Do 2 divided by 3x and get an answer of 2/3 x=2/3
----------------------------------------------------------------------------------
3x+6y=2 get rid of 3x and put down 6y=2
Do 2 divided by 6y and get an answer of 1/3 y=1/3

a) Work out the value of V
b) Expand 3p(p + 5)
c) Solve 4(k - 6) = 20
Answer:
a.7
b.
[tex]3 {p }^{2} + 15p[/tex]
c.k=11
Step-by-step explanation:
a.V=5x + 2y ,x=3,y= -4
V=5(3)+2(-4)
=15+(-8)
=15-8
=7
b.3p(p + 5)
=
[tex]3 {p}^{2} + 15p [/tex]
