Answer: 10
Step-by-step explanation:
These types of questions involve ratios. So 2.5: 25 is equal to 25 : 250 and all i did was multiply both sides by 10. Then it says that he only has 1 pound of ground beef so 25* 1/25 is equal to one, and then 250 * 1/25 is equal to 10.
1/4 = x/360
4×9 = 36 so 4 × 90 = 360
also multiply the numerator by 90 and you get
1/4 × 90/90 = 90/360
The first one is 37 and the second one is 49
Answer:

Step-by-step explanation:
Corresponding angles of two parallel lines are always equal. The angle on "top" of
corresponds with the angle marked as
. Therefore, its measure must also be
.
Since these two angles form one side of a line which has 180 degrees, we have the following equation:

Combine like terms:

Subtract 15 from both sides:

Divide both sides by 3:

Answer:
B
Step-by-step explanation:
because 4 and 3 are grouped together you would add them first. this would change the outcome of the problem.
