Answer:

cost of 1 brush = $ 5.25

cost of 1 tube of paint = $ 3.5

Step-by-step explanation:

here's the solution,

let the cost of a brush be x

and the cost of each tube of paint = y

now,

from above statement we get,

=》4x + 2y = 28

=》6x + 8y = 59.50

multiplying equation 1 with 4

=》4 × (4x + 2y) = 28

=》16x + 8y = 112

now, subtracting equation 2 from the newly derived equation 1

=》16x + 8y - 6x - 8y = 112 - 59.50

=》10x = 52.50

=》x = 52.50 ÷ 10

=》x = 5.25

now,

plugging the value of x in equation 1,

=》4x + 2y = 28

=》(4 × 5.25) + 2y = 28

=》21 + 2y = 28

=》2y = 28 - 21

=》y = 7 ÷ 2

=》y = 3.5

Need help i don't know what im doing?​
AveGali [126]

Answer:

X=5

Step-by-step explanation:

f(1)= -1^2+4(1)+12=15

f(2)= -2^2+4(2)+12=16

f(3)= -3^2+4(3)+12=15

f(4)= -4^2+4(4)+12=12

f(5)= -5^2+4(5)+12=7

g(1)=1+2=3

g(2)=2+2=4

g(3)=3+2=5

g(4)=4+2=6

g(5)=5+2=7

so g(5)=f(5)= X=5

Which part of the graph best represents the solution set to the system of inequalities y<_ x+1 and y+x<_ -1
Pavel [41]

Hello!

Remember that the symbols: ≤ and ≥ are graphed as a solid line. While the symbols: < and > are graphed as a dotted line.

Also, before graphing, it would be better to convert both equations to slope-intercept form.

y ≤ x + 1 is already in slope-intercept form.

y + x ≤ -1 is not written in slope-intercept form. (Slope-intercept form: y = mx + b)

y + x ≤ - 1 (subtract x from both sides)

y ≤ -x - 1

Graphing those lines, you get the graph below. You can see that Part C best represents the solution set systems of inequalities, because that is where both of the shaded lines intersect.

Answer: Part C

4+5(p-1) how to expand brackets and then simplify
Valentin [98]

Step-by-step explanation:

these are multiplications.

you could also write

4 + 5×(p - 1)

now, we need to calculate the contents of brackets (if we can), then do the multiplications and divisions, before we can do the then remaining additions and subtractions.

if we cannot do a calculation directly (because there is a variable involved), we need to do and document the single steps for the individual parts involved.

so,

4 + 5×(p - 1) = 4 + 5×p + 5×-1 = 4 + 5p - 5 = 5p - 1

remember, a multiplication of 2 expressions is done by multiplying every term of one expression with every term of the other expression and adding the results up (by considering their individual signs, of course).
