Answer:
- The equation StartFraction 1 over 8 EndFraction (x + 16) = StartFraction 76 over 8 EndFraction represents the situation, where x is the food bill.
- The solution x = 60 represents the total food bill.
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
The food bill (x) plus the tip (16) ;divided by the number of friends (8) , must be equal to the total amount spent (76) divided by the number of friends (8):
Mathematically speaking:
(x+16) /8 = 76/8
(x+16) /8 = 9.5
(x+16) = 9.5 (8)
x+16 = 76
x = 76-16
x= 60 (food bill)
So, the correct options are:
- The equation StartFraction 1 over 8 EndFraction (x + 16) = StartFraction 76 over 8 EndFraction represents the situation, where x is the food bill.
(1/8 (x+16) =76/8)
- The solution x = 60 represents the total food bill.
Answer:
There is no answer because we dont know how many square inches his moms present is.
Answer:
Step-by-step explanation:
Given:
1/2(ln(xx + yy) − ln(zz))
Now,
From the properties of log function,
1) n × ln(x) = ln(xⁿ)
and,
2) ln(A) - ln(B) = 
applying the properties in the given equation
we get the above equation as:
( using the property 2 we get (ln(xx + yy) − ln(zz) = 
or
⇒ ( using the property 1 i.e n × ln(x) = ln(xⁿ) )
expression as an equivalent expression with a single logarithm is
If you gave away 280 of 600 business cards and you would like to know what percent of the cards is left, you can calculate this using the following steps:
600 - 280 = 320 cards are left
320 / 600 = 8 / 15 = 0.5333 = 53.33%
The correct result is D. 53.33%.
The quotient means divide.....the difference means subtract
the quotient of 5 and the difference of a number and 3..
5 / (x - 3) <== ur expression
the product means multiply....decreased means subtract
the product of a number and 20 decreased by 11..
20x - 11 <== ur expression
the difference means subtract
the difference of 30 and a number, multiplied by 2
2(30 - x) <== ur expression
