Devaughn is 13 years younger than Sydney. The sum of their ages is 79 . What is Sydney's age?
Answer: 46 years old
Step-by-step explanation: If Devaughn is 13 years younger than Sydney,
we can represent Sydney's age as x and Devaughn's age as x - 13.
Since the sum of their ages is 79, we have x + x - 13 = 79.
This simplifies to 2x = 92.
Dividing both sides by 2, we have x = 46.
So sydney is 46 years old.

x=60
Step-by-step explanation:
Answer: The equation 60 + x= 3x -70 could be set up to solve for x.
Step-by-step explanation:
The two remote interior angles sums will equal to the exterior angle .
Meaning that angle 60 plus angle x has to equal to angle 3x -70.
60 + x= 3x -70 Now solve for x by adding 70 to both sides
+70 +70
130 + x = 3x Now subtract x from both sides
-x -x
130 = 2x Divide both sides by

Ms. W has 400 followers on Twitter and is gaining 75 followers each day. Mrs. Hill has 1,000 followers on Twitter, but is losing 25 followers a day. How many days will it take them to have the same number of followers?
Answer:
It takes 6 days.
Step-by-step explanation:
First, you have to form expressions for both of them in terms of x. Let x be the number of days :
Ms. W = 400 + 75x
Mrs. Hill = 1000 - 25x
Next, you have to compare it as we want to find out how many days in takes for them to have the same number of followers :
400 + 75x = 1000 - 25x
75x + 25x = 1000 - 400
100x = 600
x = 6

1. Which equation represents a line that passes through the point (-2,6) and is parallel to the line whose equation is 8x – 4y = 6?
Answer:
y=2x+10
Step-by-step explanation:
First, let's put the equation into slope-intercept form. We get y=2x-3/2.
Parallel lines have the same slope, so the slope of the line will be 2.
We then substitute the point into the equation to find the y-intercept.
We get y=2x+10

75 – 3.5y – 4y = 4y + 6
y=6
Step-by-step explanation:
[tex]75 - 3.5y - 4y = 4y + 6[/tex]
Collect like terms and simplify
[tex] - 3.5y + 4y - 4y = 6 - 75 \\ - 11.5y = - 69[/tex]
Divide both sides of the equation by-3.5
[tex] \frac{ - 11.5y}{ -11.5} = \frac{ - 69}{ - 11.5} [/tex]
Simplify
[tex]y = 6[/tex]
The value of the y in the given equation is 6.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
For example, 3x – 5 = 16 is an equation.
Given that, an equation, 75 - 3.5y - 4y = 4y + 6, we need to find the value of y,
75 - 3.5y - 4y = 4y + 6
Combining the like terms,
75 - 6 = 4y + 4y + 3.5y
69 = 11.5y
y = 6
Hence, the value of the y in the given equation is 6.

What is scale factor?Scale factor is the factor which is used to enlarge or smaller the original figure.
Scale factor is the ratio of representation measurement of the figure to the original figures.
On a blueprint, an architect drew a 12-inch line to represent the length of a 30-foot room. Thus, the scale factor of foot to inch is,

what's y intercept on a graph of y = -5x + 6
The y-intercept on a graph of y = -5x + 6 is 6.
What are intercepts?The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.
We have a linear equation,
y = -5x + 6.
The general slope-intercept form,
y = mx + b.
Where m is the slope and b is the y-intercept.
Comparing,
b = 6.
Therefore, 6 is the y-intercept.

drop one test score if he chooses.
84%, 71%, 64%, 90%, 75%, 44%, 98%
Which measure of center should Peter choose so he can have the highest percentage possible?
O Peter should choose the mean after dropping one test score.
Peter should choose the mean without dropping one test score.
O Peter should choose the median after dropping one test score.
O Peter should choose the median without dropping one test score.
t would be best if Peter's report card percentage was based on the mean and if he could drop a percent, he should drop the 44%.
