add all the numbers until u left with no numbers left except the number left over and then add xs and then subtract the number from 23 to isolate x. then divide x by the number left over from the right side.
-6+9-19=-16
x+2x=3x
so -16+3x= 23
+16 +16
3x=39
(3/3)x=39/3
x=13
hope it helps!
It is c=3r because 2*3 is 6 and 4*3 is 12 and it is always times 3.
Answer:
area = x^2 - 4x
Step-by-step explanation:
a = x(x-4)
a = x^2 - 4x (x times x is x^2, x times -4 is -4x)
Answer:
See explanation.
Step-by-step explanation:
13. (4*5)/2 = 10
14. 5*7=35 7-3=4 8-5=3 (4*3)/2 = 6 35+6 = 41
15. 3*4 = 12
16. (4*4)/2 = 8 8*4=32 4*2=8 16*8=128 128-32 = 96
Let me know if you want me to better explain how I solved any of these.
The required proportion of the blue paint is 18 liters.
Given that,
The ratio of yellow and blue colors is 2:3
The proportion of the yellow color is 12 liters.
The proportion of blue color is to be determined.
<h3>What is the Ratio?</h3>
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Let the proportion of the blue color is x,
Now, the ratio can be given as
12 / x = 2 / 3
x = 12 * 3 / 2
x = 18
Thus, the required proportion of the blue paint is 18 liters.

The question given is incomplete, a proper question could be
A paint store mixes yellow and blue paint in a ratio of 2:3 to make green paint. If they used 12 liters of yellow paint, how many liters of blue paint were used?
