Answer:
The answer would be: √x+3=13
Step-by-step explanation:
A radical equation is an equation with at least one variable put on a radical form. In this question, there is only one kind of variable which is x. Then, you need to find the equation where x is in the radical form. The radical form can be expressed with square root symbol.
The option with √x would be only √x+3=13
Long story short your answer would = 5.
Answer:
18 pounds
Step-by-step explanation:
Quantity of Rift valley blend mixed = 90 pounds
Quantity of Arabian Mocha blend = 27 pounds
Mixture proportion of Rift valley blend : Arabian Mocha blend
= 90 : 27
= 10 : 3
This implies that for every 10 pounds of Rift Valley blend, we mix 3 pounds of Arabian Mocha.
So since the proportion is constant for the secret blend the let the unknown quantity of Arabian Mocha be "x" while the Rift Valley quantity be 60 pounds
Using constant proportion
10 :3 is equivalent to 60: x
Using the law of ratio, we have
3/10 = x/60
Cross multiplying both sides, we have:
10x =180
Dividing both sides by 10, we have:
x = 180/10
x = 18 pounds
So the quantity of Arabia Mocha to be used is 18 pounds.
