Answer:
$46.20
Step-by-step explanation:
His earnings: 8.8*7 = 61.6
He gave away 1/4, so he has 3/4 left
3/4*61.6=46.2
Answer:
y=2x
Step-by-step explanation:
it is a proportional relationship and the slope is 2
1.65 + 0.85x= $20
0.85x=$18.35
x=21 10/17
first you write the equation
then you have to subtract 1.65 from the equation but you also have to subtract it from 20
then you divide 0.85 from 0.85x and from the 18.35 left over from subtracting 1.65 from 20
then you should get x=21 10/17 (simplified) but the decimal form is a ongoing fraction so you can just round it up to the nearest hundredth
Answer:
-1.8, -5/4, 3.2, 2/3
Step-by-step explanation:
Answer:
The true solution is x=4/9
EXPLANATION
The logarithmic equation given to us is
We need to use the quotient rule of logarithms.
When we apply this law the expression becomes
We now take the antilogarithm of both sides to get
We square both sides to get,
We evaluate to obtain,
This simplifies to
We divide both sides by 36 to get
We simplify to get,
