Answer:
76
Step-by-step explanation:
When you solve the equation you will do parentheses first (10+2) which equals 12 then you carry everything down. Next you will multiply 3 x 12 to get 36 then you carry the 20 and 2 down. Next you will multiply 20 by 2 to get 40 and then add 36 + 40 to get 76.
3(10+2) +20 x 2
3(12) +20 x 2
36 + 20 x 2
36 + 40
76 : answer
Hi!
2.06m + 6.13 = 17.78
First subtract 6.13 from both sides
2.06m + 6.13 - 6.13 = 17.78 - 6.13
2.06m = 11.65
Divide by 2.06 on both sides
2.06m/2.06 = 11.65/2.06
m = 5.7

Answer:
1 in : 50 mi
Step-by-step explanation:
You can eliminate the choices that don't make any sense by comparing the given numbers to the offered choices:
given:
15 in : 750 mi
__
A. 1 in : 50 mi . . . . . . . . equivalent to dividing the given ratio numbers by 15
B. 15 in : 100 mi . . . . . . same inches, wrong miles
C. 1 in : 750 mi . . . . . . . wrong inches, same miles
D. 1 mi : 50 in . . . . . . . . both inches and miles are wrong (the ratio has the units swapped)
__
In the given ratio, the numerical number of miles (750) is 50 times the numerical number of inches (15). This is the ratio you're looking for among the answer choices. You need to pay attention to both the numerical values and their associated units.
