The equation would be
g + (g + 9) = 45
2g + 9 = 45
- 9
2g = 36
÷ 2
g = 18
18 + 9 = 27

Answer:
Blue cars, B = 63 cars
Step-by-step explanation:
Let the blue cars be B.
Let the red cars be R.
Given the following data;
Ratio of B:R = 9:7 = 9 + 7 = 16
Red cars, R = 49
To find the number of blue cars;
First of all, we would determine the total number of cars using the expression;
R = 7/16 * x = 49
7x = 49 * 16
7x = 784
x = 112 cars
Now, we can find the number of blue cars;
B = 9/16 * 112
B = 1008/16
Blue cars, B = 63 cars
Answer:
1.67
Step-by-step explanation:
after the decimal we have the
tens
hundreths
thousanths
(usually math doesn't ask you to go farther than the thousanths place)
because 15/9 is 1.66666, you will go to the hundreths place and round that six. Six is one more than five so it gets rounded up. That changes the decimal to 1.67. You do not change it to 1.7, because it asked you to round to the nearest hundred not the nearest tens
Answer:
4650 add 1500+1800+3400 u get 6700
then you get the tuition cost then subtract it by 6700
your final answer is 4650 dollar
