How do I do this? 50 points plus brainliest.
Answer:
you just gotta look at the angles, the middle letter is usually what's being focused on
17. angle QMR is less that TMS
18. angle QMR and angle TMS are supplementary angles
19. angle QMR and angle MTS are vertical angles
20. If measure angle QMT = 70 degrees, then measure angle RMS is 70 degrees because they are congruent

Find the lengths of the diagonals of rectangle WXYZ
WY = 6x - 7
XZ = 3x + 2
The length of each diagonal is units
Answer:
√(45x²-72x+53)
Step-by-step explanation:
When you insert diagonals, two rightangled triangles are formed.
To find the length of the diagonals, we put the rectangles into pythagorus's theorem:
a²=b²+c²
a²=(6x-7)²+(3x+2)²
a²=36x²-84x+49 + 9x²+12x+4
a²=45x²-72x+53
a=√(45x²-72x+53)

Answer:
D. 10
Step-by-step explanation:
8x-14=5x+34
8x-5x=34+14
3x=48
x=48/3
x=16
8x-14+5y+16 = 180
8(16)-14+5y+16 = 180
128-14+5y+16=180
5y=180-128-16+14

if Richard worked for 7 dollars and made 9 dollars and hour how much would he make?
Answer:
$63
Step-by-step explanation:
I believe you meant Richard worked for 7 hours and made $9 per hour.
In order to know how much Richard earned for 7 hours, you have to multiply Richard's salary rate with his number of working hours.
7 hours x 9 dollars/hour = $63Therefore, Richard earned $63 for his 7-hour work.
Additional Information
Another example is: if Richard worked for 10 hours, you just have to multiply his salary rate again to his number of working hours.
10 hours x 9 dollars/hour = $90plssss helppppppppp thxxxxxxxxxxx

Answer:
18/24 and 8/245/15 and 9/156/9 and 4/9Step-by-step explanation:
We can go through the list of fraction pairs and see if the denominators are both factors of one of the offered "common denominator" values.
2, 9 -- no
4, 6 -- 24
5, 10 -- no
3, 5 -- 15
6, 9 -- no
20, 3 -- no
3, 9 -- 9
Based on the above results, the answers appear to be ...
common denominator 24: 18/24 and 8/24 (from 3/4 and 2/6)
common denominator 15: 5/15 and 9/15 (from 1/3 and 3/5)
common denominator 9: 6/9 and 4/9 (from 2/3 and 4/9)
Two sides of a triangle measure 25 cm and 35 cm. Which of the following could be the measure of the third side?
A 3 cm
C 8 cm
B 6 cm
D 11 cm
Answer:
D. 11 cm
The two shorter sides of a triangle must add to be more than the longest side:
a + b > c
If b = 25 and c = 35, then we have:
a + 25 > 35
a > 10
So the shortest side has to be longer than 10 cm.

and mZMLK = 164º. Find x.
M M
Р
L
K K
9514 1404 393
Answer:
(c) x = -7
Step-by-step explanation:
An angle is equal to the sum of the angles into which it is divided.
∠MLK = ∠MLP + ∠PLK
164° = (x +31)° +(x +147)°
164 = 2x +178 . . . . . . collect terms
-14 = 2x . . . . . . . . . . . subtract 178
-7 = x . . . . . . . . . . . . . divide by 2
Write a rule for the nth term of the arithmetic sequence described below.
A5 =
91 and a20 =
1
an=
A25=
Answer:
an = 115 + (n - 1) (-6)
a25 = - 29
Step-by-step explanation:
We use the definition for the nth term of an arithmetic sequence:
an = a1 + (n - 1) d
a5 = 91 = a1 + (5 - 1) d
91 = a1 + 4 d
a20 = 1 = a1 + (20 - 1) d = a1 + 19 d
1 = a1 + 19 d
now we subtract term by term one expression from the other
90 = 4 d - 19 d
90 = - 15 d
divide both sides by -15 to isolate d
d = 90 / (-15) = -6
Now we can calculate what a1 is using for example:
1 = a1 + 19 d
1 = a1 - 114
add 114 to both sides:
115 = a1
Then our general expression for the sequence is:
an = 115 + (n - 1) (-6)
We can now use it to calculate the value of a25:
a25 = 115 + (24) * (-6) = -29
