2x + 22 = 4(x + 3)...distribute thru the parenthesis
2x + 22 = 4x + 12...subtract 2x from both sides, subtract 12 from both sides
22 - 12 = 4x - 2x...simplify
10 = 2x...divide both sides by 2
10/2 = x...reduce
5 = x <==
Answer:
X=-4 last answer i got i hope it is helpful have a nice day
Step-by-step explanation:
Let's solve your equation step-by-step.
6(3x+5)=7(2x+2)
Step 1: Simplify both sides of the equation.
6(3x+5)=7(2x+2)
(6)(3x)+(6)(5)=(7)(2x)+(7)(2)(Distribute)
18x+30=14x+14
Step 2: Subtract 14x from both sides.
18x+30−14x=14x+14−14x
4x+30=14
Step 3: Subtract 30 from both sides.
4x+30−30=14−30
4x=−16
Step 4: Divide both sides by 4.
4x
4
=
−16

Answer: 80 degrees</h3>
===========================================================
Explanation:
Angle 3 and the 100 degree angle are corresponding angles. They are both in the southeast quadrant of their four-corner angle configuration. Assuming the lines that look horizontal are parallel, this would mean angle 3 is 100 degrees. Recall that corresponding angles are congruent when we have parallel lines.
Once we know that angle 3 = 100, we will use this to find angle 4.
Angles 3 and 4 add to 180. They form a straight angle or straight line.
(angle3)+(angle4) = 180
(100) + (angle4) = 180
angle4 = 180-100
angle4 = 80 degrees
The answer is A. sin40=6/x
