The required value of x is 7.
In the given statement is:
m/HGS = 3x + 5,
m/SGF=21x +3, and m/HGF = 176º.
and, to find the value of 'x'
The two angles, ∠HGS & ∠SGF, when combined, will result in ∠HGF
m ∠HGS = 3x + 5
m ∠SGF = 21x + 3
m ∠HGF = 176°
Set the equation:
m ∠SGF + m ∠HGS = m ∠HGF
Plug in the corresponding terms to the corresponding variables:
21x + 3 + 3x + 5 = 176°
24x + 8 = 176°
24x = 176° - 8
24x = 168°
x = 168°/24
x = 7
Hence, The required value of x is 7.

Line p has an equation of y=8/3x+2. Line q, which is parallel to p, includes the point (-2,-5). What is the equation of line q?
Answer:
y = [tex]\frac{8}{3}[/tex] x + [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{8}{3}[/tex] x + 2 ← is in slope- intercept form
with slope m = [tex]\frac{8}{3}[/tex]
Parallel lines have equal slopes , thus
y = [tex]\frac{8}{3}[/tex] x + c ← is the partial equation
To find c substitute (- 2, - 5) into the partial equation
- 5 = - [tex]\frac{16}{3}[/tex] + c ⇒ c = - 5 + [tex]\frac{16}{3}[/tex] = [tex]\frac{1}{3}[/tex]
y = [tex]\frac{8}{3}[/tex] x + [tex]\frac{1}{3}[/tex] ← equation of parallel line

Answer:
DE = 34
AC = 68
Step-by-step explanation:
since DE are midpoints, you can create this equation: 2(8x + 2) = 20x - 12
solve:
16x + 4 = 20x - 12
16x + 16 = 20x
16 = 4x
4 = x
plug this into both equations to find each side:
DE: 8(4) + 2 = 34
AC: 20(4) - 12 = 68
we know our answer is right because AC is twice as long as DE

Which function has an inverse that is also a function?
o f(x) = 4x + 7
Oh (2) = 17
O j(x) = 3cº
O g(x) = 2 – 3
Answer:
G(x) = 2x - 3 has a linear inverse which is a function.
k(x) = -9x2 has a square root inverse that is a function on only the interval x < 0.
Step-by-step explanation:
The inverse of a function is a reflection across the y=x line. This results in switching the values of the input and output or (x,y) points to become (y,x). This can be done algebraically in an equation as well. Begin by switching the x and y in the equation then solve for y.
x = 2y - 3 -------> y = x/2 + 3/2 is linear and a function.
-9y2 = x --------> y = √(-x/9) is a square root that is a function on only the interval x < 0.
Absolute value does not have an inverse function.
x = -20 is a vertical line which is not a function.

r. Parks spent $96.30 on 3 hats and 6 key chains.
a. If each hat cost $15.50, how much did each key chain cost?
Each key chain costs $
.
Question 2
b. Claire said each chain costs $0.83. Why is her answer unreasonable? Explain.
Answer:
1. $8.30
Step-by-step explanation:
so 3 hats were purchased and each cost 15.50 so
15.50*3=46.50
and the rest of the 96.30 is 6 keychains so
96.30-46.50=49.80
and there is 6 keychains
49.80/6=8.30
Each key chain was $8.30
Claire's answer is unreasonable because when we got the price of the keychains all together in Claire's mind the total for the keychains would be $4.98, which we clearly got the total for the keychains at $49.80.
The cost of each keychain is $5.79 which parks bought.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, Parks spent $96.30 on 3 hats and 6 key chains and the cost of each hat is $15.50 and assuming the cost of each key chain to be 'x'.
Therefore, The expression that represents this context is,
3×15.50 + 6x = 96.30.
6x = 96.30 - 46.50.
6x = 49.8.
x = 49/8.6.
x = 5.79.
So, The cost of each key chain is $5.79.

32% of what weight is 60 oz
Answer:
200 oz
Step-by-step explanation:
Just use the equation
0.32x=200
The number of 32% which result in 60 oz would be 18.75
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a' the percent that considered thing is of "a" is b%. Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts.
We need to find the number that is state 32% of number weight is 60 oz
Let the unknown number is represneted by b.
It can be written by;
32% x b = 60
32/100 x b = 60
0.32 x b = 60
b = 60/0.32
b = 18.75
Therefore, the number would be 18.75

We need to convert 2/3 and 7/8 to have a common denominator. They both have a common denominator of 24 so...
We convert:

7/8 x 3/3 = 21/24

Answer:
E: x = 13
F: x = 1.5 or 3/2
Step-by-step explanation:
This is for E:
x + 2/3 = 5
All you do is first multiply 5 * 3
and you will get 15
x + 2 = 15
Then you subtract from 15
15 - 2 = 13
So x = 13
This is for F:
10(x - 1) = 5
So all you do is distribute the 100 with x -1
10 * x = 100x
10 * -1 = 100
10x - 10 = 5
Then you add 10 to 15 because the number is -10
5 + 10 = 15
10x = 15
Now you divide by 10 on both sides
10x/10 = 15/10
10x/10 = x
15/10 = 3/2
So the answer for F is 3/2 or 1.5
