Answer:
90
Step-by-step explanation:
5x – 2y + (7x – y)
Combine like terms
12x -3y
Let x = 7 and y = -2
12(7) -3(-2)
84 +6

There is 2 midpoints on a line segment.
hello i see that no one has answered your question yet well im here to help:)
(1,-19),(-2,-7)
so here one way you can find the slope
i usually always use this to help me to keep it in order
------------------
(X1,Y1)(X2,Y2)
X2-X1
Y2-Y1
use this and your garanteed to get the right answer everytime
------------------
X = -2 – 1 = -3
Y = -7 – -19 = 12
once you do that you divide if possible
12/-3
which gives you -4
so your answer is -4
its really not hard you just got to get use to it
hope it help you:)
The Markup percentage is mathematically given as
M=42%
<h3>What is Mark up percentage?</h3>
The markup % may be determined by dividing the gross profit of a unit (the difference between its sales price and the amount it cost to create or buy for resale) by the amount that unit originally cost. If a product sells for $12 but only costs the corporation $8 to produce it, the markup percentage for that product is 50%, which can be calculated as (12 - 8) divided by 8.
Generally, the equation for is Total cost price mathematically given as
TCP= Pay+insurance
Therefore
TCP=35.5*1.6
TCP=284/5
Generally, the equation for is Total selling price mathematically given as
TSP=89.99+7.99

Addition: 93 can be added six times to determine the total
and division can be used to check your answer since it's the inverse operation of multiplication...take your solution of 558 and divide it by 6 (or 93) to see if 93 times six equals 558
