Answer:
x = 10
Step-by-step explanation:
10^2= 20, therefore
X=10Answer:
x = ± 2[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Given
x² = 20 ( take the square root of both sides )
x = ± [tex]\sqrt{20}[/tex] = ± [tex]\sqrt{4(5)}[/tex] = ± [tex]\sqrt{4}[/tex] × [tex]\sqrt{5}[/tex] = ± 2[tex]\sqrt{5}[/tex]
The sum of 9 and the quotient of x and 7 is 11
Answer:
Expression: 9 + x/7=11
x=14
Step-by-step explanation:
The expression would 9 + x/7=11 because it says the sum of 9 and the quotient of x and 7. Quotient means the answer to a division problem, and sum means the answer to an addition problem.
x=14 because when you subtract 9 from both sides of the equation, you will get x/7=2
Then, 7*2=14, so that is why x=14

point U is on line segment TV . given TU=4 UV=5x and TV=3x+6 determine the numerical lenth of TV
Using the segment addition postulate, the numerical length of TV is: 9 units.
What is the Segment Addition Postulate?According to the segment addition postulate, if U lies between line segment TV, therefore:
TV = TU + UV
Plug in the values:
3x + 6 = 4 + 5x
Solve for x
3x - 5x = 4 - 6
-2x = -2
x = 1
TV = 3x + 6 = 3(1) + 6
TV = 9 units

Answer:
B. 9
Step-by-step explanation:
So when solving a question like this, you may try to find what 3⁴ is and what 3² is and divide, but there is a much easier way to do this. Remember:
[tex]\frac{a^{m}}{a^{n}}=a^{m-n}[/tex]
This can be used to find [tex]\frac{3^{4}}{3^{2}}[/tex] without finding what 3⁴ is. This is how we would do it:
[tex]\frac{3^{4}}{3^{2}}=3^{4-2}=3^{2}=9[/tex]
And now we get the solution, 9, which is answer choice B.

Solve 8w-3r=45 for r. Show your work.
Answer:
r = 8/3w − 15
Step-by-step explanation:
Let's solve for r.
8w−3r=45
Step 1: Add -8w to both sides.
−3r+8w+−8w=45+−8w
−3r=−8w+45
Step 2: Divide both sides by -3.
−3r/−3 = −8w+45/−3

Answer:
Slope = -7/4
Step-by-step explanation:
Let's find the slope between your two points.
(0,0) ; (−4,7)
(x1,y1) = (0,0)
(x2,y2) = (−4,7)
Use the slope formula:
m = y2−y1 / x2−x1
= 7−0/−4−0
=7/−4
= −7/4
Answer:
m= −7/4

You are making a picture frame in shop class. Two pieces of wood are cut to form complementary angles so they fit together properly . One angle needs to be (2x +23) and the other angle needs to be (3x +27). What is the measure of the larger angle?
Answer:
Step-by-step explanation:
The measure of the angles are 51° and 39°.
What is a complementary angle?When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.
Given:
Two pieces of wood are cut to form complementary angles.
One angle needs to be (2x +23) and the other angle needs to be (3x +27).
We have to find the measure of the larger angle?.
According to given question we have
Two angles are complementary when their sum is equal to 90°.
So, ( 2x + 23 ) + ( 3x + 27 ) = 90°
5x + 50° = 90°
5x=40°
x = 8°
Putting value of x in the angles given :
( 2x + 23 )° = 2(8°) + 23° = 39°.
( 3x +27 )° = 3(8°) +27° = 51°.
Therefore, the measure of the angles are 51° and 39°.
