Answer:
2.25
Step-by-step explanation:
Change the fraction so that the denominator is something that's a factor of 100
9/4 = x/100
9 x 25 = 225
-----------------------
4 x 25 = 100
225/100
Now divide to get your decimal
225/100 = 2.25
Answer: Use the base times hight to get the hypotenuse
Step-by-step explanation:
Answer:
Step-by-step explanation:
1. 6 L = 6000 mL
2. 54000 mL = 54 L
3. 11000 mL = 11 L
4. 13 L = 13000 mL
5. 23500 mL = 23.5 L
6. 0.201 L = 201 mL
Exact form: 32415/2
Decimal form: 16207.5
First, let's isolate one of the variables (preferably, y)
5y = -9x + 28
y = -1.8x + 5.6
Input this into the second equation:
5x + 9(-1.8x + 5.6) = 56
5x + -16.2x + 50.4 = 56
-11.2x + 50.4 = 56
-11.2x = 5.6
x = -0.5
Knowing this:
-2.5 + 9y = 56
9y = 58.5
y = 6.5
The solution set is (-0.5, 6.5)
