The answer is 420. I hope that it is right and next time use a calculator.<span />
Answer:
x=7
y=2
Step-by-step explanation:
10 + 2x = -2y ➡y = -5-x
replace y with -5-x in the first equation
-5-x-x = 9➡ -2x-5 = 9 ➡-2x = 9+5 ➡ x = -7
now use this information to find value of y
y - (-7)=9 ➡y = 2
Given:
ratio 3:2
amount to split : 2.5
ratio of 3:2 has a total of 5 because 3 + 2 = 5
So 3 is 3/5 of the ratio and 2 is 2/5 of the ratio based on the total.
2.50 is the amount that needs to be distributed using the ratio. It is the total.
3/5 x 2.50 = 1.50
2/5 x 2.50 = 1.00
So, 3:2 is equal to 1.50 : 1.00
