What is the measure of angle TGF?
A
28 degrees
B
58 degrees
C
86 degrees
D
94 degrees
Answer:
C
Step-by-step explanation:
Sum of angles in triangle is 180 degrees.
28°+58°+ x= 180 degrees
x=94 degrees
sum of angles on a straight line is 180 degrees
thus, 94 degrees + ? = 180 degrees
?= 86 degrees
angle TGF is 86 degrees
What is the simplified form of the following expression?
Answer:
242
Step-by-step explanation:
Simplify the following:
11 ((9^2 - 5^2)/2^2 + 8)
Hint: | Evaluate 2^2.
2^2 = 4:
11 ((9^2 - 5^2)/4 + 8)
Hint: | Evaluate 5^2.
5^2 = 25:
11 ((9^2 - 25)/4 + 8)

Answer: 242
The variables x and y are related proportionally. When x = 4, y = 18. Find y when x = 24. When x = 24, y =
Answer:
when x = 24, y = 108
Step-by-step explanation:
The equation relating x and y is
y = kx ← k is the constant of proportion
To find k use the condition when x = 4 , y = 18, then
18 = 4k ( divide both sides by 4 )
4.5 = k
y = 4.5x ← equation of proportion
When x = 24, then
y = 4.5 × 24 = 108

If y=5 when x=-3, find x when y=-1
If y=25 when x=15, find y when x=6
Answer:
5. x=0.6 or 3/5 (it's just the fraction and decimal form)
6. y=10
Step-by-step explanation:
5. We are given y=5 and x=-3, so whenever and need to find x if y=-1
We need to find the "x" for the second proportion
Using this information we can create a ratio or proportion. To understand this better, (usingy=5 and x=-3) we can say that for every 5 of something (y) we have -3 of something (x). We can create a "key" using the proportionality:[tex]\frac{y}{x}[/tex]
here is our proportion [tex]\frac{5}{-3} *\frac{-1}{x}[/tex]
lets cross multiply first, 5x=-1(-3) this simplifies to 5x=3, divide 5 from both sides, 5x/5=3/5 and you x=3/5, so this means that x is 3/5 or 0.6 as decimal
6. Lets set up our "key" again [tex]\frac{y}{x}[/tex],
our ratio is for every 25 something (y) we have 15 something(x) or 25/15 or 25:15
[tex]\frac{25}{15} *\frac{y}{6}[/tex] this is our proportion, lets cross multiply to solve for "y"
25*6=15y this simplifies to 150=15y
lets divide both sides by 15, 150/15-15y/15 and we get our final answer
10=y so our why for this is 10
Answer:
6. [tex]\displaystyle 10 = y[/tex]
5. [tex]\displaystyle \frac{3}{5} = x[/tex]
Step-by-step explanation:
You are simply dealing with direct proportional relationships:
[tex]\displaystyle \frac{y}{6} = \frac{25}{15}; 10 = y[/tex]
These are considered equivalent improper fractions. When simplified, you get [tex]\displaystyle 1\frac{2}{3}.[/tex]
_______________________________________________
[tex]\displaystyle \frac{-1}{x} = \frac{5}{-3}; \frac{3}{5} = x[/tex]
If you look closely, you can tell that there is a 1 being used here, and that you need to divide it by the multiplicative inverse of [tex]\displaystyle \frac{5}{3},[/tex]which is [tex]\displaystyle \frac{3}{5},[/tex]and sinse both terms are negative integers, you leave the result as is.

The following triangle is isosceles. Write an equation and use it to solve for x.
Options:
x = 3
x = 2
x = 6
x = 4
Answer:
x = 6
Step-by-step explanation:
Since the sides are congruent (definition of isosceles triangle), the angles must also be congruent.
Step 1: Set up equation
4x + 20 = 8x - 4
Step 2: Solve for x
Subtract 4x on both sides: 20 = 4x - 4Add 4 to both sides: 24 = 4xDivide both sides by 4: 6 = xRewrite: x = 6Shana and Marie will update parts of their computer system. They will update the motherboard for $259.99, 2 USB
ports for $39.95 each, and the DVD drive for $79.49. Shana will save $12.50 per week and Marie will save $15.50
per week. Which inequality can be used to find w, the number of weeks it will take Shana and Marie to save enough
money for the parts?
Answer:
12.5w = 419.38
and
15.5w = 419.38
Step-by-step explanation:
find the total cost of all the computer parts.
= 259.99 + 2* 39.95 + 79.49 = $419.38
Shana will save $12.50 per week and Marie will save $15.50
per week
therefore we can create two inequalities
Shana:12.50 * w = 419.38
12.5w = 419.38
w = 419.38/12.5
w = 33.5504
Marie15.50*w = 419.38
15.5w = 419.38
w = 419.38/15.5
w =27.0568

Answer:
small = 1.25
medium = 2.10
large = 4.50

The question is in the picture please explain.
Answer:
x = 78
Step-by-step explanation:
Look at Triangle DBH. Two of its angles are known. Let y = <DHB
47 + 31 + y = 180 All triangles have 180 degrees. Combine the left.
78 + y = 180 Subtract 78 from both sides.
78-78+y = 180-78 Combine
y = 102
Notice that y + x = 180 They form a straight line.
102 + x = 180 Subtract 102 from both sides.
x = 78
You should notice that x is an exterior angle. (I didn't at first).
Exterior angles are the sum of the two remote interior angles which in this case, are 31 + 47 = 78
Much shorter and much easier.

4+x = 5x+2. find x. 180 is the total of this equation
Answer:
x=
Step-by-step explanation:
4+x-2=5x+2-2
2+x-x=5x-x
2=4x
2/4
Answer:
x = 45.5
Step-by-step explanation:
Move one side of the equation to the other side of the equal sign.
4 + x = 5x + 2
x = 5x - 2
=4x - 2
Then put the 180 on the empty side because the total is 180.
180 = 4x - 2
Then solve for x
182 = 4x
45.5 = x

In a board game, negative number cards represent moving backward and positive number cards represent moving forward. For example, Nuha drew a card with 444 and moved forward 444 spaces. Raha draws a card with 000. What does 000 represent in the board game? Choose 1 answer:
Answer:
you do not move forward or backward but instead, remain in the exact position
Step-by-step explanation:
** The numbers are repeated in this question 444 is actually 4 and 000 is actually 0 **
In these board games and in many other concepts zero (0) acts as a neutral value since it is neither a negative nor a positive. In this board game, drawing a card with a value of 0 means that you do not move forward or backward but instead remain in the exact position that you already are. Usually, this also means that your turn is skipped and there is no change in your board piece's/character's status or position in the game
Answer:
stay in the same spot because its 0

1. So far this month Raul calculated that he will ear $40 in commission for his
$280 in product sales. If Raul would like for his commission to be $132, how much
does her need in sales? *
Answer:
Raul needs sales of $924.
Step-by-step explanation:
It looks like Raul earns commission at 1/7 of his sales. (40/280 = 1/7).
[tex]\frac{40}{280}=\frac{132}{x}\\ 40x = 280*132\\x=924[/tex]
