The sum of three numbers is 69. If the second number is equal to the first diminished by 8, and the third number is 5 times the first. What are the numbers?
2 answers:
We let x as the first number7x - 8 = 69 The answer for the second question. x = 11 y = 3 z = 55
X = first number

Okay so first you distribute to both sides(the arrows). then you subtract 5y to both sides and bring everything down. then you subtract 7 to both sides and get -27=9y and divide by 9 to get the y alone .
x =(-2-√-12)/8=(-1-i√ 3 )/4= -0.2500-0.4330i
x =(-2+√-12)/8=(-1+i√ 3 )/4= -0.2500+0.4330i
x = 1/2 = 0.500
Answer:
m∠7 = 64°
Step-by-step explanation:
∠7 and ∠8 are supplementary meaning they add up to 180°.
m∠7 + m∠8 = 180°
m∠7 + 116° = 180°
m∠7 = 64°
