(1/2) * x^3 + 3.4y when X = 2 and Y = 5.
= (1/2) * (2^3) * 3.4(5)
= (1/2) * 8 * 17
= (1/2) * 136
= 136/2
= 68.
Answer:
He owes $175
Step-by-step explanation:
He paid a 30% deposit of 75 dollars. Let the total cost be x
30% of x is 75 dollars. In equation form
.30x = 75
Divide each side by .30
.30x/.30 = 75/.30
x =250
The total cost is 250
Since he already paid 75
The amount he still has to pay is
250-75 = 175
Answer:
y = 4
Step-by-step explanation:
4*y = 4y
4*4 = 16
4y+16=32
to get 4y alone, we subtract 16 from 32.
32-16 = 16
4y = 16
to get y alone, we divide 4 by 16
16/ 4 = 4
so, y = 4
Answer:1=1
Step-by-step explanation:Let your no.= x
double the number=2x
add 4 = 2x+4
subtract same number=2x+4-x
subtract 3=2x+4-x-3
I get my number plus 1=x+1
so equation we get
2x+4-x-3=x+1
x+1=x+1
x=x
it means x is equal to all real number
So your number can be any real number
The answer is B - The number or value being raised to a power
