Matt, Steve and John sold magazines for a school fundraiser. John sold two less than Matt. Steve sold twice as many as John. Write a simplified expression representing the total amount of magazines sold
Answer:
4x - 6
Step-by-step explanation:
Matt: x
Steve: 2(x - 2)
John: x - 2
Total magazines sold:
x + 2(x - 2) + (x - 2)
x + 2x - 4 + x - 2
4x - 6
Reduce the fraction to the lowest term
[tex] \frac{4}{8} [/tex]
Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
To reduce the fraction to the lowest term, we divide the like term by the GCF of its numerator and denominator.
Here,
As 4 and 8 have the GCF as 4 itself. We divide both the numerator and denominator with the GCF (4).
Hence,
[tex]\frac{4}{8}\\=\frac{4}{8}/\frac{4}{4} \\=\frac{4/4}{8/4} \\=\frac{1}{2}[/tex]
find the slope of the line passing through the given points or the given line.
Answer:
y = -1
Step-by-step explanation:
since this is a straight, horizontal line, we know that this will just be a y value line
since the line passes through the y axis at y = -1, this is the equation for the line
y = -1
What is the quotient of 6 and -1/2?
How does the value of 874.12 change if the decimal point is moved two places to the left?
I would think it would be 8.7412
What is an equation of the line that passes through the points (5,-2) and ( -5,0)?
Put your answer in fully reduced form.
9514 1404 393
Answer:
y = -1/5x -1
Step-by-step explanation:
When given 2 points, it can work well to start with the 2-point form of the equation for a line.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (0 -(-2))/(-5 -5)(x -5) +(-2)
y = 2/(-10)(x -5) -2
y = -1/5x -1 . . . . . eliminate parentheses and collect terms
-(x + 3) -2(4x -3)

What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
We have to given that;
In honors math increased by 12% in this year students.
Now, if S represents students.
Then, An expression to represent this situation is,
⇒ S + 12% of S
⇒ S + 0.12S
⇒ S (1 + 0.12)
⇒ 1.12S
Thus, The expression is true.

Step-by-step explanation:
Tell whether the x- and y-values in the table show a proportional or non-proportional relationship. If the relationship is proportional, tell the rule. Select one:
aProportional; x = 3/7y
bNon-proportional
cProportional; x=1/3y
dProportional; x=2/5y
Answer:
b. Non-proportional
Step-by-step explanation:
A table of values that represents a proportional relationship will have the same ratio of every pair in the given table. That is, y/x will result in the same value all through for every given pair.
The table of values given does not show a proportional relationship, because the ratio of y to x of each given pair of values are different and unequal:
y/x = 3/1 ≠ 5/2 ≠ 7/3 ≠ 9/4
Therefore, it is non-proportional.

What slope would make the lines
parallel?
y = x + 6
y = [?]x+4
Answer:
1
Step-by-step explanation:
Parallel lines have the same slope and it is understood for 1 to be the number in front of the x if there isn't one so, the slope or number for the second line would also be 1.
Order these numbers from least to greatest.

O <4
0 0 <16
[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Inequalities.
so we get as,
(w+6)/2 < 5
so we get as,
w+6 < 10
=> w < 10-6
=> w < 4
so the answer is,
w < 4

Answer:
x = -7
m<GFD = 50°
m<CFD = 40°
Segment FD doesn't bisect <CFG because the angles aren't equal.
Step-by-step explanation:
<CFD and <GFD are complementary angles and their sum is 90°
-5x + 5 -7x + 1 = 90° add like terms
-12x + 6 = 90
-12x = 84 divide both sides by -12
x = -7
m<CFD is -5x + 5 ➡ (-5)×(-7) + 5 = 40°
m<GFD is -7x + 1 ➡ (-7)×(-7) + 1 = 50°
