12. True
13. False
14. False
15. True
16. False
17. x = 2.5
Step-by-step explanation:
With problems 11 to 16, You have to replace the h in the equations with 3 and see if the equation is true or not.
11. You can simplify the equation by solving the number in the parentheses first. So the problem would be 3(3 - 4) since you replace the h with a 3. (3 - 4) equals -1. So now the problem simplified is 3(-1) which is 3 x -1 which equals -3. Meaning that 3(h - 4) = -3 is true since h is 3.
With 17 and 18, you have to replace what number you think is x. A easy way of doing this is working in reverse.
17. So 4x has to equal 8 when 2 is taken away. To find this out, we add 2 to 8 which would equal 10. Then we divide 4 from 10 which equals 2.5. In order make sure that this is correct, we will put the equation back into normal formula. So 4x - 2 = 8 becomes (4 x 2.5) - 2 = 8. (4 x 2.5) equals 10, so 10 - 2 = 8.
The highest number would be 75.39

Answer:
Step-by-step explanation:
2) string and wall are parallel
3) parallel lines intersected by a common third line make corresponding angles.
4) A and B have the same angle measure.
The total amount of blue glass was=(2/3)*(30 9/10)=
=(2*30)/3 (9*2) /(10*3)=60/3 18/30=20 3/5.
The answer is 20 3/5
Congratulations!! you are right!
