Answer:
<ADC = 131
Step-by-step explanation:
< ADC = <ADB + < BDC
The large angle is the sum of the two smaller angles.
<ADC = 89+42
=131
X=number looked for
Twice the difference of a number and 8=2(x-8)
Three times the sum of the number and 3=3(x+3)
We suggest this equation:
2(x-8)=3(x+3)
2x-16=3x+9
2x-3x=9+16
-x=25
x=-25
The number is -25 .
To check:
Twice the difference of a number and 8=2(-25-8)=2(-33)=-66
Three times the sum of the number and 3=3(-25+3)=3(-22)=-66
Answer:
28
Step-by-step explanation:
(x-19)7=63
x-19=9
x=28
