Answer:
x=26
Step-by-step explanation:
3x +12 =90
subtract 12 from each side
3x=78
divide 3 from each side
x=26
Answer:
x = 26
Step-by-step explanation:
Before we begin, we must first remember that to solve for x, we have to get the variable (x) by itself.
To start, you would first subtract 12 from the left and right side of the equation.
3x + 12 - (12) = 90 - (12)
The 12 would cancel out on the left side (12 - 12 = 0) and you would now be left with 3x = 78.
Next, you would divide the left and ride side by 3.
3x ÷ 3 = 78 ÷ 3
This gives you the answer of 1x = 26 or x = 26

An angle measuring 32 degrees has a complement that measures ( 2x-16 ) degrees. What is the value
Answer:
x=37
Step-by-step explanation:
Complementary angles add up to 90 degrees.
Let's first find the measure of the complement.
90-32=58
Now we can set the numerical value of it equal to the expression it gave us.
2x-16=58
We have to isolate x.
Lets add 16 to both sides
2x=74
Divide both sides by 2.
x=37
What is a correct name for the angle shown? Line segments R S and S T combine to form an angle. Angle R Angle S Angle R T S Angle S R T
Answer:
(B)Angle S
Step-by-step explanation:
Given that line segments RS and ST combine to form an angle.
The angle formed by the two line segments occur at the common end point of the two segments which in this case is S.
Therefore the angle is formed at S.
This can be written in the following ways:
[tex]\angle RST, \angle TSR$ or simply \angle S.[/tex]
The correct option is B.
Answer:
What is a correct name for the angle shown? Option B
(A) Angle R
( B) Angle S <====== Option B Hope this helps

A 48-inch board is cut into two pieces. One piece is three times the length of the other. Find the length of the shorter piece. The shorter piece is ______
inches long.
Answer:
12 inches long
Step-by-step explanation:
So you have the ratio x : 3x
4x = 48
x = 12
Plug in:
12 * 1 = 12
The length of the shorter piece is 12 inches if the 48-inch board is cut into two pieces. One piece is three times the length of the other.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
A 48-inch board is cut into two pieces. One piece is three times the length of the other.
Let x and y be the length.
x = 3y
x + y = 48
3y + y = 48
y = 12 inches
x = 36 inches
Thus, the length of the shorter piece is 12 inches if the 48-inch board is cut into two pieces. One piece is three times the length of the other.

45 over 43 as a percent
Answer: 104.65%
Step-by-step explanation: 45/43=1.0465 so you just move the decimal to the right 2 places to make it a percent. It’s over 100% because 45 is higher than the total of 43.
Solve for x:
-0.6x > 3
A. X < -5
B X < -0.2
C X > -5
D. X > -0.2
I don’t need an explanation just the answer thank you
Answer:
A
Step-by-step explanation:
Given
- 0.6x > 3
Divide both sides by - 0.6, reversing the symbol as a result of dividing by a negative quantity, thus
x < - 5 → A

Of all 840 sixth grade students in a math school, 700 participated in the math Olympiad. Of all 910 fifth grade students, 745 participated in it.From which grade did more students participate in the Olympiad?
Answer:Sixth grade
Step-by-step explanation:
Given
There are [tex]840[/tex] sixth grade students out of which [tex]700[/tex] Participated in math olympiad
also no of fifth grade students[tex]=910[/tex]
Fifth graders who participated in math olympiad [tex]=745[/tex]
Since [tex]745>740[/tex]
There are more fifth graders in Olympiad [Numerically]
Percentage wise
Percenteage of sixth graders who participated in Math olympiad[tex]=\dfrac{700}{840}\times 100=83.33\ \%[/tex]
Percenteage of Fifth graders who participated in Math olympiad[tex]=\dfrac{745}{910}\times 100=81.86\ \%[/tex]
So, a greater Population of Sixth graders participated in math olympiad compared to Fifth graders as [tex]83.33\ \%>81.86\ \%[/tex]

Answer:
80,000 people will vote. I'm pretty sure
Step-by-step explanation:
You first divided 200,000 by 10 then multiply it by 4 and you get 80,000. You're welcome, if its right.
Answer:
80.000 peple will vote
Step-by-step explanation:
Four out of ten is equivalent to the fraction 4/10 in which when simplified it can be written as 2/5 (I simplified the fraction to make it easier), then you just multiply the fraction by the amount of people =200,000. When multiplied you will get the result 80.000. Hope this helps :)

Answer:
122 employees
Step-by-step explanation:
So, first you have to find 22% OF 100 WHICH IS 22. (100x0.22= 22) Then, since they have to lay off 22% more people you add the 22% of 100 (22) to the 100. (100+22=122) This means that they have laid off 122 employees this year. I hope this helps!
PLS HURRY I NEED THIS ANSWERED RIGHT NOW!!! Brittney has twice as much money as Sun. Together, they have $60. Let x represent the amount of money Sun has. What expression represents the amount of money Brittney has? What expression represents the amount of money that Brittney and Sun have together? What is the equation described in this problem?
Sun's money = x
Brittney's money = 2x
x + 2x = $60
3x = $60
3x/3 = 60/3
x = 20
So amount that Brittney has is 2x.
The amount they have together is 3x
The equation that describes the problem is 3x = $60
Answer:
Brittney has twice as much money as Sun. Together, they have $60. Let x represent the amount of money Sun has.

solve similar triangles
Answer:
22.5
Step-by-step explanation:
With similar triangles you don't have to solve for any angle, as both triangles are alike, just different sizes in the case. So 20/12 = 5/3 or 1.66, and the same for 27.5/16.5, so using that, we have 37.5/1.66 which is 22.5

while hiking you see a 100ft observation tower on top of a 1100ft hill. The angle of elevation to the top of the tower is 6. How far away is the tower?.
Answer:692.82 ft
Step-by-step explanation:
Given
Height of tower is [tex]h=100\ ft[/tex]
Tower is mounted at the top of [tex]H=1100\ ft[/tex] hill
angle of elevation [tex]\theta =60^{\circ}[/tex]
Using figure we can write
[tex]\tan \theta =\dfrac{h+H}{\text{Distance}}[/tex]
[tex]\tan 60^{\circ}=\dfrac{100+1100}{\text{Distance}}[/tex]
[tex]Distance =\frac{1200}{\tan 60^{\circ}}[/tex]
[tex]Distance=\frac{1200}{\sqrt{3}}[/tex]
[tex]Distance=692.82\ ft[/tex]
