Thanks for asking for the explanation, everyone wants just the answer, You want to know how to solve the problem , great. :)
Step-by-step explanation:
Our strategy and one you can use on any triangle problem.
the interior angles add to 180° . Remembering that, seems to me, that very often is the "key" to figuring out triangle problems.
keeping that in mind, we know to add up all the inside angles to 180
180= A + B + C
from this particular triangle then, we have
A = 6X
B = 90 ( b/c that's what the small red square is telling us, it's a 90 angle )
C = 5x - 2
put that all together
180 = 6x + 90 +5x - 2
now use your algebra skills to solve for X ( and to be fair, this is where lots of people struggle, the algebra skills are not so good )
so I'll just go slow
put like terms together
180 = 11x + 88 ( I just added the terms with an x, and the constant terms )
move the 88 over to the other side by subtracting
92 = 11x
divide both sides by 11
92 / 11 = x
8.3636 = x
now that we know x, plug it into the expression for the angle next to the y angle in the picture
5x - 2
5(8.3636) - 2
39.8181
then y is the other part of another 180 pair of angles sooo use that again
180 = 39.8181 + y
solve for y
140.1818 = y
Hope this helps, ask any questions you may have, :)

Diego is asked to solve 3x−8=4(x+5). What do you recommend he does to each side first?
Answers
Answer:
He would factor out 4(x+5)
Step-by-step explanation:
You can't do much until the 4(x+5) is factored out.
Once it is then it'd be 3x-8=4x+20
Then you subtract 3x on both sides and subtract 20 on both sides.
You'd be left with -28=x

Answer:
D. h(x) = 5x² +12x +9
Step-by-step explanation:
The final constants are mostly different, so you can simplify your work by just figuring that one.
h(x) = g(x) -f(x)
h(0) = g(0) -f(0) = -7 -(-16) = +9 . . . . . matches choice D
__
If you want to figure the whole expression ...
h(x) = g(x) -f(x)
h(x) = 12x² +7x -7 -(7x² -5x -16)
h(x) = 12x² +7x -7 -7x² +5x +16
h(x) = (12 -7)x² +(7 +5)x +(-7 +16)
h(x) = 5x² +12x +9 . . . . . matches choice D
A major credit card company requires monthly payments equal to or greater than 8% of the total balance.A consumer has a credit card balance of $320. Write an inequality that represents acceptable payment amounts.
Answers
Answer:
320 x 0.08 = X
In the case, a payment equal to or greater than $ 25.60 would be considered acceptable by the company.
Step-by-step explanation:
Given that a major credit card company requires monthly payments equal to or greater than 8% of the total balance, and a consumer has a credit card balance of $ 320, the following calculations must be performed to determine an inequality that represents acceptable payment amounts:
320 x 0.08 = X
25.6 = X
Thus, in the case, a payment equal to or greater than $ 25.60 would be considered acceptable by the company.

how do you solve (7^-1)^-1 and 5^2 * 5^4 * 5^-3
Answers
Answer:
Step-by-step explanation:
exponents raised to a - power is an inverse function probably not the right word
a^-b = 1/(a^b) example 4^-2 = 1/(4^2) = 1/16
so (7^-1)^-1 is a double inverse which is back to the original number 7
inverted 7 twice
(7^-1)^-1 = (1/7)^-1 = 1/(1/7) = 7 trust me or use your calculator
since the coeffients are the same just add the powers... some exponent rule
5^2 * 5^4 * 5^-3 = 5^(2+4-3) = 5³
here is it written out
5^2 * 5^4 * 5^-3 = 5² × 5^4 × 5^-3 = (5×5) × (5×5×5×5) × (1/5×1/5×1/5)
5×5 × 5× (5×5×5 × 1/5×1/5×1/5) (5×5×5 × 1/5×1/5×1/5) = 1
5×5×5 = 5³
so
The first equation is y = -2x + 8

explain to a 7th grader how to find the x intercept and the y-intercept on a graph
Answers
The Slope-Intercept form of the equation of a line is: y=mx + b
where m=slope (often called "rise over run")
b = y-intercept (the point on the y-axis when x=0)
Given a slope and a y-intercept point [ (0,b) ],
(1) plot the point (0,b)
On the y-axis (x=0), find the point b.
(2) Now, do the "rise over run" exercise. For a slope of m, you go up m units on the y-axis for 1 unit of increase on the x-axis. For example, if m=4 the next point after (0,b) would be (1,b+4). Now, note that a negative m (a negative slope) means that the y-values decrease as the x-values increase.
Two points determine a line. "Connect the dots" and extend in both directions.

A triangle has side lengths of (6p – 7) centimeters, (7p – 2) centimeters,
and (6q – 9) centimeters. Which expression represents the perimeter, in
centimeters, of the triangle?
Answers
Given:
A triangle has side lengths of (6p – 7) centimeters, (7p – 2) centimeters,
and (6q – 9) centimeters.
To find:
The expression that represents the perimeter, in centimeters, of the triangle.
Solution:
We know that, perimeter of a triangle is the sum of its all sides.
[tex]Perimeter=(6p-7)+(7p-2)+(6q-9)[/tex]
Combining like terms, we get
[tex]Perimeter=(6p+7p)+6q+(-7-2-9)[/tex]
[tex]Perimeter=(13p)+6q+(-18)[/tex]
[tex]Perimeter=13p+6q-18[/tex]
Therefore, the perimeter of the triangle is represented by the expression [tex]13p+6q-18[/tex] centimeters.
A triangle has side lengths of (6p – 7) centimeters, (7p – 2) centimeters, and (6q – 9) centimeters.
To find:
The expression that represents the perimeter, in centimeters, of the triangle.
