Answer:
1152 grams of iron
Step-by-step explanation:
We are trying to figure out how many grams of iron are required to make a certain alloy. So, we see that the alloy has to be combined with 144 grams of zinc , so first, we find out how many times does it take to make 9 into 144, which can be done through division.
144 / 9
==> 16
So if it takes 16 times to make the required amount of alloy to combine 144 grams of zinc, we must also apply the grams of iron multiplied by 16.
72 * 16
==> 1,152
Therefore, it takes 1152 grams of iron will be needed to 1. combine with zinc and 2. to make the new alloy.
x=60° because if 150°<u>=90°+</u>60° so a line is 180° consequently
90°+30°+x=180°
120°+x°= 180°
x°= 180°-120°= 60°
Answer:
Well,you obviously want to do the parenthesis first but since almost all the numbers contain it you go from left to right so do the 12-4-6 and then move to the right like a regular equation, hope this helps :)
