Answer:
10 degrees
Step-by-step explanation:
A straight line equals 180 degrees. We already know we have 110 degrees, so we subtract 180-110 and get 70. Now, we can set up an equation:
We have to isolate x, so divide both sides by 7
70=7x
_____ = 10=x
7
x=10 degrees
Hope this helps!
1: one solution
Explanation: We see that the variable x is equal to 9 (and only 9). Therefore there is only one solution
2: infinitely many solutions
Explanation: When an equation has infinitely many solutions, it means that any real number (aka <em>all real numbers</em>) would satisfy that equation. For example 2x = 2x. Any number you plug in for x would result in both sides being equal. So you know an equation has infinitely many solutions if both sides are the same
3: no solution
Explanation: 7 does not equal 4 so you can't solve this equation.
4: no solution
Explanation: 7 is not less than 7, that is impossible, so there is no solution.
5: one solution
Explanation: 8 <em>is</em> greater than or equal to -2, so this inequality is true, meaning it represents one solution
Answer:
the son is 30 and the daughter is 15
Step-by-step explanation:
the mom is 55 in 15 years
