Multiply .30 and 50 ... which is 15
First you need to set up your equation.
If you read the question it states one equation IS THE SAME AMOUNT of another equation so here it is:
3x+7= 2x+18
You want to find out x in both equations so I’ll help step by step
1. Subtract 2x from both sides
This leaves you with x+7=18
2. Then subtract 7 on both sides
This leaves you with x=11
So x equals 11 for equations.
You can check by plugging in 11 in x. If you get 40 on both sides....
CONGRATS!! You did it
I hope this helped. Have a great day!
Answer:
80°
Step-by-step explanation:
According to angles rule,
100° + x = 180° [linear pair]
=> x = 180°-100°
=> <u>x</u><u> </u><u>=</u><u> </u><u>80</u><u>°</u><u>(</u><u>Ans</u><u>)</u>
