Write an Expression:
4.25*9 = X
4.25*9 = 38.25 in²
m = 5a
m + a = 30
Because we already know the value of m, we can find the value of a.
5a + a = 30
<em><u>Combine like terms.</u></em>
6a = 30
<em><u>Divide both sides by 6</u></em>
a = 5
Now that we know the value of a, we can find the true value of m.
m = 5a
m = 5 * 5
m = 25

Answer:
Answer is D.
Step-by-step explanation:
Answer:
21/4
Step-by-step explanation:
21 y = -4x Divide 21 on both sides
y = -4/21x Slope is -4/21
Perpendictulare lines have a slope that are the negative inverses of eachother, so flip the 4 and the 21 and make it positve instead of negative
Answer:
missing angle = 70 degrees
Step-by-step explanation:
180 -120 =60, because supplemenatery angles add up to 180 degrees.
sum of all angles of a triangle = 180. so 180-60-50=70 degrees
