Melinda adds $2 less than Marcus
Step-by-step explanation:
Melinda:
135 - 75 = 60
60 ÷ 5 = 12
She saves $12 each week
Marcus:
y=14x+25
y=14x5+25
y= 70+25
y=95
95-25=70
70÷5= 14
Marcus saves $14 each week

a stack of 500 pieces of paper is 1.875 inches tall derion guesses that each piece of paper is 0.015 inches thick. explain how you know that derions answer is not correct.
compute the thickness of each piece of paper. show your reasoning
Answers
Answer:
Derions answer is not correct becuase 500 x 0.015=7.5 inches. If he got this as an answer that would meen that the stack of paper is 7.5 inches tall, which is not correct.
If we divide 1.875 by 500 we get 0.00375 which is the thickness of each sheet of paper.
Jazmyn uses 2 gallons of paint to paint 5 walls. He uses 4 gallons of paint to paint 10 walls. How many gallons of paint does he use per wall?
Answers
Answer:
2/5 gallons
Step-by-step explanation:
If it takes 2 gallons of paint to paint 5 walls, then the amount of gallons used per wall can be calculated by comparison
[tex]5 walls = 2 gallons \\ 1 \: wall = x \: gallons \\ by \: cross \: multiplication \\ 5 \times x = 2 \times 1 \\ 5x = 2 \\ x = \frac{2}{5} [/tex]
Hence, 2/5 gallons of paint is used per wall.

Sam has 6x + 8 dollars saved. Teresa has saved 14x + 32 dollars. Together they have $220 saved. How much money have they each saved individually?
Answers
Step-by-step explanation:
given,
dollars saved by Sam = 6x + 8
dollars saved by Teresa = 14x + 32
total money = $220
a/q
money saved by,
sam + Teresa = $220
so,
6x + 8 + 14x + 32 = 220
20x + 40 = 220
20x = 220 - 40 = 180
x = 180/20 = 9
x = 9
now,
money saved by,
Sam = 6x + 8 = 6(9) + 8 = $62
Teresa = 14x + 32 = 14(9) + 32 = $158
therefore,
money individually saved by Sam is $62 and by Teresa $158.

what is the slope on an equation
Answers
Answer:
Formula
Slope of a line
Once your equation is in slope-intercept form: "y = mx+b", the coefficient of "x" (the "m") is the slope. The constant (the "b") is the y-intercept at (0, b).
Step-by-step explanation:
slope= dy/dx

Graph this line using the slope and y-intercept:
y=–2/5x + 6
Click to select points on the graph.
Answers
Step-by-step explanation:
start at the 6 then go down 2 Y and over 5X
Answer:
See explanation below
Step-by-step explanation:
Start at (0,6) which is the y-intercept where b=6, then go down 2 units, and 5 units to the right which represents the slope m=-2/5 and mark that point. Repeat until you feel you're done and then connect the points to form the line of the equation.
For example, the next point after (0,6) would be (5,4) because by going 5 units to the right and 2 units down, we can represent this as (0+5,6-2) which is (5,4). I've attached a graph with some points to help draw the line.
Hope this was helpful!

Step-by-step explanation:
Mikey's family is taking a road trip. Their car can travel no more than 260 miles without needing to refill the gas tank. They have traveled 112 miles since they last filled the gas tank.
Mikey knows that the inequality representing this situation is 112 + x ≤ 260.
Select from the drop-down menu to correctly interpret the solution of this inequality.
Mikey's family can drive_____more miles before they need to refill the gas tank.
A. at most 148
B. at least 148
C. more than 372
D. more than 372
Answers
Answer:
A
Step by step:
you subtract 112 from 260 to isolate the variable. Then you get x is less than or equal to 148. Which means that the most miles that can be traveled is 148 miles before filling up.
Mikey's family can drive at most 148 more miles before they need to refill the gas tank. which is the correct answer would be option (A).
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
As per the given situation, the required inequality would be as
⇒ 112 + x ≤ 260
To isolate the variable, remove 112 from 260. The result is that x is less than or equal to 148.
⇒ 112 + x - 112 ≤ 260 - 112
⇒ x ≤ 148
This indicates that the maximum distance that may be traveled before filling up is 148 miles.
Therefore, his family can drive at most 148 more miles before they need to refill the gas tank.

What’s the answer and how do i find slope?
Answers
You can find the slope by putting the two ordered pairs into the formula: y2-y1/x2-x1.
y2 is the second y, being 8 in your case.
x2 is the second x. Being -2 in your case.
y1 is the first y, being -6 in your case.
x1 is the first x. Being 0 in your case.
After plugging in these numbers you will get 8- -6/-2-0. This will get you 14/-2. which will equal -7, the slope.
I can explain more if you want.
Hope this helped!! :)
Answer:
the answer should be -7
Step-by-step explanation:
you find slope by using the formula y2-y1/x2-x1
