Answer:
12
Step-by-step explanation:
The ratio of cars to trucks to motorcycles is $4:3:2.
If there are $42$ cars and trucks total,
To get how many motorcycles are there
Sum up the ratio of cars and trucks 4:3= 4+3 = 7
Sum up the ratio of cars and trucks and motorcycles
4+3+2 =9
Let the total number of cars and trucks and motorcycles be represented as A
The total number of cars and trucks in the question is 42
(7/9) x A = 42
7A/9 = 42
cross multiply
7A = 42×9 = 378
A= 378/7 = 54
The total number of cars and trucks and motorcycles is 54
To get the number of motorcycles can be calculated through
a. The total number of cars and trucks and motorcycles subtracted by the number of cars and trucks = 54-42=12 or use the ratio which is
2/9 × 54 = 2×6=12

Let T=Num of T-shirts 27
Let M=Total amount of money spent for 27 T-shirts.
Let X=Cost of 1 T-shirt
M(Total cost)/T(#of T-shirts) = X (Cost of one shirt)
Answer:less than
Step-by-step explanation:
-15+3-7=-19
-9-1+16=6
A positive will always be bigger than a negative
As given m is a midpoint of ab. So am is half of ab.
So we can write
As given am = 3x+3 , ab = 8x - 6.
So
So x = 6.
So length of am = 3x+3 = 3*6 + 3 = 21
