Answer:
x= 20 and y= 12
Step-by-step explanation:
nickel is 5 cents and quarter is 25 cents,
let x be number of nickels and y be number of cents
x+y = 32
5x + 25y = 400
you get x= 20 and y= 12
Answer:
1944x^2.
Step-by-step explanation:
sqrt 2x^2 * sqrt18^5
= sqrt2x^2 * (sqrt(9^5*2^5))
= sqrt 2 x^2 * (sqrt9^5 * sqrt 2^5)
= sqrt2 x^2 * (243* sqrt2^5)
= 2^0.5 (243 * 2^2.5) x^2
= 2^3 * 243 x^2
= 1944x^2.
Answer:
24 pounds
Step-by-step explanation:
Let's call the weight of the empty wheelbarrow X, and the weight of dirt to fill the wheelbarrow Y.
So, we can formulate the following equations:
X + Y = 60
X + (1/4)*Y = 33
Subtracting the second equation from the first one, we have:
3/4 * Y = 27
Y = 27 * 4 / 3 = 36
Now, we can calculate X:
X + 36 = 60
X = 24 pounds
