Is x = 6 a solution to the equation 5(x – 3) = x + 13?
Follow the steps to find out.
1. Rewrite the equation 5(x – 3) = x + 13 with 6 substituted for x. Write a question mark over the equal sign to show that you're testing to see if the equation is true.

Yes, both equations will always work, but yes, at times it is more logical to use one over the other. for instance:
x-4y=6
x+4y=12
we see here that elimination would best fit:
x+x+4y-4y=6+12
or:
x=2y-3
7x+3y-81=23
substitute (2y-3) for x.
Also, once you have a single placeholder, put it ito quadratic form (ax^2+bx+c=0)
and use the quadratic formula:
x=(-b±sqrt(b^2-4ac))/2a

yes

Mario start collecting stamps in January and buys 12 stamps each month.Karen starts collecting stamps in July and buys 18 starts each month. how many months after Karen starts collecting stamps will she have the same number of stamps as Mario?
Answer:
12 months
Step-by-step explanation:
Given that:
Mario:
12 stamps per month
Since January
Karen :
18 stamps per month
Starts on july
Number of stamps collected by Mario till the end of June :
12 * 6 = 72 stamps
For Mario :
72 + 12x
For karen:
18x
Where x is the number of months after karen starts :
Equate both equations
72 + 12x = 18x
72 = 18x - 12x
72 = 6x
x = 72/6
x = 12
After 12 months
Number of months after karen starts, will they have same amount of stamp

Find the circumference of the circle.
A: 47,1 in
B: 22 in
C: 10.5 in
D: 35 in
Answer:
C≈47.12, or 47.1
Step-by-step explanation:
To find the circumference you just use the formula C=2[tex]\pi[/tex]r.
The radius of your circle is 7.5 which is half of 15, now multiply 2[tex]\pi[/tex](7.5) which gives you your answer!
An even easier way to do this is to use the other formula C=d[tex]\pi[/tex],
Just multiply your diameter (which is what was given to you) by pi and you also get your answer!
Hope this helps! :)
Solve the system of equations.
5x - 7y = 58
y = -x + 2
х =
y =
Answer:
the x and y is 6 and -4 respectively
Step-by-step explanation:
The computation of solving the system of equations is given below:
Given that
5x - 7y = 58
And,
y = -x + 2
Put y value in the first equation
5x - 7(-x + 2) = 58
5x + 7x - 14 = 58
12x = 58 + 14
12x = 72
x = 6
So y = -6 + 2
= -4
Hence, the x and y is 6 and -4 respectively

A triangle has one angle that measures 70 degrees, one angle that measures 42 degrees, and one angle that measures 68 degrees. What kind of triangle is it?
Answer:
Scalene Acute Triangle
Step-by-step explanation:
The triangle above is an "acute triangle" because the measurement of each angle is less than 90°. However, there are three types of acute triangle and these are: Equilateral Acute Triangle, Isosceles Acute Triangle and Scalene Acute Triangle.
When all the angles have the same measurement of less than 90°, then it is an Equilateral Acute Triangle. If only two angles have the same measurement, it is an Isosceles Acute Triangle. If none of the angles are the same but all are less than 90°, which also means that the sides are also unequal, then it is an Scalene Acute Triangle.
The triangle above has different angle measurements of less than 90°. Therefore, it is an Scalene Acute Triangle.

The algebraic rule for a reflection over the x-axis is one for the following:
A. (x,y), -axis → (-x,y)
B. (x,y), -axis → 0,x)
C. (x,y), -axis → (x,- y)
D. (x,y)x-axis →(-x-y)
Answer:
C
Step-by-step explanation:
When reflecting around the x axis, the x value stays the same and the y- will change.

Last week Jack ran 18 miles more than Pranav. Jack ran 34 miles. How many miles did Pranav run?
Hello there!
Step-by-step explanation:
If Jack runs 34 miles, and Pranav runs 18 less, this signifies that we need to subtract 18 from Jack's total miles to get his miles ran.
34 - 18 = 16
Pranav ran 16 miles.
1/10( x + 130) = -2(3-X)
I need help
Answer:
x = 10
Step-by-step explanation:
1/10(x + 130) = -2(3 - x)
x + 130 = -20(3-x)
x + 130 = -60 + 20x
x - 20x = -60 - 130
-19x = -190
x = 10
