use each diagram to solve for x​ - 1

Answers

Answer 1
Answer: 2. 6x+3= 45°

6x = 42°
x = 7


3. 5x + 19 = 7x - 1

-2x + 19 = -1
-2x = -20
x = 10

5(10)+19= 50+19= 69°
7(10)-1= 70-1= 69°

Which us shorter 1/3 2/5 3/10 or 1/4

Answers

The shortest fraction is 1/4.

The common denominator is 60, so you see how much times the denominator can go into 40 and multiply the numerator by that much. For example 3/4 and the common denominator is 20. Four can go into 20 five times so you multiply 3 five times and the fraction is 15/20

Change 2x+2y=6 into y=mx+b format please!!!

Answers

If you want it in that format and simplified, this is it. y=-x+3
If you dont need it simplified then the answer is 2y=-2x+6
y=-1x+3 or y=-x+3

Because x is 1 so either one would work. :)

Which of the following equations models the relationship of angle A to the length of the line segment BC in the figure below.

Answers

Let the line segment BD be x, then sin A = x/15
or, x = 15sinA
Also y^(2) = x^(2) + (25)^(2) \n = (15sinA)^(2) + 625 \n =225 sin^(2) A+625 \n y= \sqrt{225 sin^(2) A+625}
The last option
