Answer: 139°
Reasoning:
Angle 3 and 5 are congruent, so you can put their expressions equal to each other and solve.
14x-1=9x+14
To isolate the x to one side, subtract the 9x from the 14x.
5x-1=14
Now to get the constants on one side, add the 1 to the 14.
5x=15
Now divide both sides by 5 to isolate the x.
5x/5=15/5
x=3
Now that we know that, we can figure out angle 3.
9(3)+14
27+14= 41
Angle 3 = 41°
Now that we know what angle 3 is, we can subtract it from 180° to figure out angle 8 since angle 3 and 8 are supplemtary angles, aka linear pairs.
180°- 41°= 139°
<h3>Double checking your answer:</h3>
41°+139°=180°

Answer:
y = 3
Step-by-step explanation:
y/9 = 2/6
y/9 = 1/3 (dividing by 2in both numerator and denominator.)
CROSS MULTIPLYING WE GET
3y = 9*1
3y = 9
y = 3
Answer:
Mildred is correct because she distributed 5 correctly
Step-by-step explanation:
We cannot tell exactly which solution goes with which student, but we believe you are saying ...
Mildred’s Solution:
5 (Negative 2 and one-fourth) = 5 (negative 2 minus one-fourth)
= negative 10 minus StartFraction 5 over 4 EndFraction
= negative 11 and one-fourth
This solution describes the correct distribution of 5. Whoever it belongs to gave the correct solution.
