Answer: 2 cars and 6 buses.
Step-by-step explanation:
x + y = 8
5x + 55y =
5 times 2 = 10
plus
55 times 6 = 330
Add 330 plus 10 = 340!
Answer:
4.54 g/cm^3
Step-by-step explanation:
d = m/v
d = 454 g ÷ 100.0 cm^3
d = 4.54 g/cm^3
3 sig figs so this answer is complete
Answer:
-1.4 and 3.4
Step-by-step explanation:
The solutions of a quadratic are the x values of the x-intercepts where the function crosses the x-axis.
Type in your equation to graph. Then zoom in on the x-axis and find where the function crosses.
See attached picture.
Solve for y in the first equation.
I'm not sure what this means. If you have choices you should list them.
(1/2)*(1/4 + 1/6) is an example of what should be given. There are two ways to solve this.
1. Use the distributive property.
1/2*1/4 + 1/2* 1/6
1/8 + 1/12 Which can be added using the LCD of 24
3/24 + 2/24 = 5/24
Method 2
Add what is inside the brackets first.
1/2 ( 1/4 + 1/6)
1/2(3/12 + 2/12 = 5/12
Now multiply by 1/2
1/2(5/12) = 5*1/(12 * 2) = 5 / 24 Same answer.
