Bob has 120 nails
One pound = 80 nails
Half a pound=40
80+40=120
Answer:
x=40 and y= 60
Step-by-step explanation:
<u>step:1</u>
Let 'x' and 'y' are two numbers
given data the sum of two numbers is 100
x+y = 100......(1)
Given difference of two numbers are
x - y = -20 ......(2)
<u>Step :2</u>
solving the equation (1) and (2)
adding the equations (1) and (2)
x+y+x-y=100-20
cancelling 'y' terms are
2 x = 80
dividing "2" on both sides, we get
x = 40
<u>Step :3</u>
substitute x = 40 in equation (1)
x + y =100
40 + y = 100
subtracting "40" on both sides, we get
40 + y - 40 = 100 -40
y = 60
Final answer:-
The two numbers are x = 40 and y= 60
24/96 simplifies to 1/4
1/4 is .25 as a decimal
.25 * 100 = 25%
So, 24 is 25% of 96.
Answer:
3√7
Step-by-step explanation:
(√3)(√21) = √(3·21) = √(3·3·7) = √(3²·7) = 3√7
__
The product of the roots is the root of the product. The product, 3·21 = 63, has a square factor that can be removed from under the radical. You need to factor out the root of that square when you simplify the expression.
