Answer:
x = 15
Step-by-step explanation:
All angles add up to 180
so,
2x + 4x + 10 + 6x - 10 = 180
combine like terms
12x = 180
divide by 12
x = 15
check it by plugging it in
2x = 2(15) = 30
4x + 10 = 4(15) + 10 = 70
6x - 10 = 6(15) - 10 = 80
30 + 70 + 80 = 180
Hunter needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for 2.5 hours and charged him $155 for parts. The total was $417.50. Write and solve an equation which can be used to determine xx, the cost of the labor per hour
Answer:
Labor costs $205 per hour.
Step-by-step explanation:
1. Subtract the cost for parts.
$417.50 - $155 = $262.5
2. Divide the labor cost by the number of hours (2.5)
$262.5 / 2.5 = 105
Answer:105

Solve for t.
-18.18 = 6t
Question 1 options:
t= -24.18
t= -3.03
t= 3.03
t= -13.18
Answer:
-3.03
Step-by-step explanation:
divide -18.18 by 6
Answer:
t= -3.03
Step-by-step explanation:
In order to solve for t, we need to isolate it. We would do this by dividing both sides by 6:
[tex]t= -18.18/6[/tex]
Therefore t= -3.03

(Sat Prep) Find the value of x)
Answer:
1. x = 120°
2. x = 115°
Step-by-step explanation:
For the first question, you can see that the two lines are parallel. This means you can use any of the alternate interior angles, alternate exterior angles, corresponding angles, consecutive interior angles, and consecutive exterior angles.
You can see that the transversal cutting the two parallel lines make a 40° angle, and through alternate interior angles, the angle next to x is also 40°.
Because a straight line is 180°, the three angles that make up the straight line will add up to 180°. So:
x + 20° + 40° = 180°
x + 60° = 180°
x = 120°
For the second question, extend the line (the left one marked with 1 arrow) to make a smaller triangle attached to the parallelogram.
Because this is a parallelogram, opposite angles are congruent. So the opposite angle of x is also x.
Straight lines are 180°, so 180 - x will be what the angle measure is. If this is too confusing, refer to the image below.
Those two angles, 50° and (180 - x)°, will add up to be the exterior angle, which is also x.
So:
50 + 180 - x = x
230 = 2x
115 = x
x = 115

A yard is equal in length to three feet. The function f(x) takes a measurement in yards (as input) and returns a measurement in feet (as output).What number will the function return if the input is 15.4?
Answer:
it should be 4.5
Step-by-step explanation:
Answer:
0.428 yd
Step-by-step explanation:
x/1 = 15.4/3
36x = 15.4
x=0.428 yd
Can someone give me the answer??? If you think u know the answer or ur guessing don’t answer it I need the right answer. Thank you
Find the value of x.
Answer:
x = 12
Step-by-step explanation:
Using the formula (which is a geometric mean):
a y
---- = -----
x a
Where a is the altitude (6), x is a projection (x), and y is the other projection (3):
6 3
---- = -----
x 6
Cross multiply:
36 = 3x
12 = x
x = 12

Here are the first four terms of a sequence.
5 9 13 17
Write an expression for the nth term of this sequence.
Answer:
4n + 1
Step-by-step explanation: The numbers are rising by 4, so this gives us 4n. Term number 1: 4n = 4, but the first number in the sequence is 5 so we have to add 1.
Term number 2: 4n = 8, but the second number in the sequence is 9 so, again, we have to add 1.

Myrtle is having a birthday party and is buying pizza for everyone. She buys 9 pizzas for $40.50 all together what is the unit rate for the pizza in pizza
find the value of 9x+4y when x=4 and y=-3
Answer:
you substitute x for 4 and so you multiply 9 x 4 which will give you 36 and then you have to add four times y so you substitute y for -3 and you add 36 - 12 which will give you 24

56 is 28% of an unknown number is (x)
Answer:
Change 28% to a decimal by moving the decimal point 2 places to the left:
28% = 0.28
Write the question as an equation to get:
56 = 0.28x
Now to solve for x, divide both sides by 0.28:
x = 56 / 0.28
x = 200
The unknown number is 200.
Step-by-step explanation:
Step-by-step explanation:
28% of an unknown number is (x)=56
28/100 of x=56
x=56×100/28=200(9+6) x 8^2 + (6+5)

Answer:
12x I think
Step-by-step explanation:
this is very confusing.
2x² + 2x - 4 = 2x ( x + 1 - 2 )
4x + 2x - 4
8x-4
4x = 2x ( x + 1 - 2)
8x + 2 - 2
8x + 4x
= 12x. I think 12x is the correct factor.
