Answer:
4
Step-by-step explanation:
5(x-3)+2x=x+9
5x-15+2x=x+9
5x+2x-x-15=9
7x-x-15=9
6x-15=9
6x=9+15
6x=24
x=24/6
x=4
Answer:
2x-2<1/2
Step-by-step explanation:
when the problem says "two less than" it means we are subtracting 2 from something, in this case, that something is "twice a number" as the problem states. So we would write 2x where x is a variable that represents any number so we have 2x-2<1/2.
The answer is A. Make sure to do multiplication/division first then add/subtract.
Answer: so those double lines on the sides of the triangle mean they're congruent to the other sides of the triangle. so it would be
<u>angle BCD</u> is congruent to<u> angle GHI </u>
Step-by-step explanation:
Triangle area formula= bh/2
Blue triangle:
10*12/2= 60
Orange triangle:
8*10/2= 40
Add the values: 40+60= 100 in^2
Final answer: 100 in^2
