Answer: x = -6
Step-by-step explanation:
Let's solve your equation step-by-step.
5(x+1) = −25
Step 1: Simplify both sides of the equation.
5(x+1) = −25
(5)(x) + (5)(1)=−25(Distribute)
5x+5=−25
Step 2: Subtract 5 from both sides.
5x+5−5=−25−5
5x=−30
Step 3: Divide both sides by 5.
5x/5 = -30/5
x = -6
Answer:
???
Step-by-step explanation:
I will use this notation m arc AB to name the measure of the arc AC in degress, going from A to B counterclock wise.
Also, note that the measure of an arc is equal to the measure of the central angle from which the arc is generated.
With that:
1) m arc AB
m arc AB is equal to the angle AOC
The angle AOC is indicated to be 49°, so m arc AB is also 49°.
Answser: 49°
2) m arc ABC
m arc ABC is equal to 360° - angle COA = 360° - 107° = 253°
3) m arc BAC
m arc BAC is equal to angle AOB + angle COA
m arc BAC = 49° + 107° = 156°
Answer: 156°
4) m arc ACB
m arc ACB = 360 ° - angle AOB = 360° - 49° = 311°
Answer: 311°
-7a + 5a < -(7-a) -(2a +1) Turns to
-7a +5a < -7 +a -2a -1 Which turns to
-2a < -1a -8 Which turns to
-1a < -8 Which turns to
1a > 8
