Answer: 40:12:30
Step-by-step explanation:
To simplify this, look for a common divisible number, which is 25
Then divide all through by 25
1000/25:300/25:750/25
=40:12:30
I hope this helps
9x-7= 29
9x-7+7= 29+7
9x= 36
Divide by 9 for 9x and 36
9x/9= 36/9
x= 4
Check answer by using substitution method
9x-7= 29
9(4)-7=29
36-7= 29
29= 29
Answer is x=4 (second choice)

Answer:
A equals 105 degrees, option 2
Step-by-step explanation:
7x + 5x gives 180. 7x and 5x lie on a line so they form a linear pair. Their sum equals 180 degrees:-
7x + 5x = 180
12x = 180
x = ![\frac{180}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B180%7D%7B12%7D)
<u>x = 15</u>
Since x is 15, we can find the lengths of 7x and 5x.
<u>7x would be 7 x 15 = 105</u>
<u>5x would be 5 x 15 = 75</u>
'A' is equal to 7x since they are vertically opposite angles.
Since 7x is 105 degrees, then A would be 105 degrees as well.
