-2x - 13 = -3x - 5
Step 1: Combine like terms
x's go with x's (-2x and -3x). To do this add 2x to both sides
(-2x + 2x) - 13 = (-3x + 2x) - 5
(0) - 13 = (-x) - 5
- 13 = -x - 5
normal numbers go with normal numbers ( -13 and -5). To do this add 5 to both sides
(- 13 + 5) = -x + (- 5 + 5)
-8 = -x + (0)
-8 = -x
Step 2: Isolate x by dividing -1 to both sides (this will take the negative sign away from the x)
8 = x
x= 8
Hope this helped!
Im assuming it would be 60 or 60.375(Work below)
Because usually when it says "out of" it means divide so i divided 8 from 21 and got 2.625 so then i took the 63 and subtracted 2.625 from that and got 60.375 so its either 60 or 60.375 again im not sure if im wrong im very sorry.

Answer:
C and D
Step-by-step explanation:
Mathematically, a unit circle is one in which the value of the radius is 1 unit
Generally, for a unit circle we have it that;
r^2 = x^2 + y^2
where (x,y) represents the coordinates of a point on the unit circle
But from above, r = 1
Thus:
x^2 + y^2 = 1
Looking at option C, by squaring each coordinate, we have
(6/7)^2 = 36/49 and the second as 13/49
by adding both, we have
36/49 + 13/49 = 49/49 = 1
Thus, we have this as a coordinate on the unit circle
For the last option;
(5/13)^2 = 25/169 and (12/13)^2 = 144/169
Adding both, we have;
25/169 + 144/169 = 169/169 = 1
So this is also a point on the unit circle
Answer:
The length of the missing side SR is 33.1 feet
Step-by-step explanation:
Let us revise the sine rule
In a triangle , where
- a is the side opposite to angle A
- b is the side opposite to angle B
- c is the side opposite to angle C
In Δ MSR
∵ MR is opposite to ∠S
∵ SR is opposite to ∠M
- By using the sine rule
∴
∵ m∠S = 101°
∵ m∠M = 37°
∵ MR = 54 feet
- Substitute them in the statement of the ratio above
∴
- By using the cross multiplication
∴ SR × sin(101) = 54 × sin(37)
- Divide both sides by sin(101)
∴ SR = 33.10626661
- Round it to the nearest tenth
∴ SR = 33.1 feet
The length of the missing side SR is 33.1 feet
