Answer:
x = 7.39
Step-by-step explanation:
log(x)²=(logx)², find the value of x
log x² = log x * log x
2log x = log x * log x
2 = log x
Take the exponent pf both sides
e² = e^logx
e² = x
x = e²
x = 7.39

<h3>Let the number be x</h3>
- Multiply all terms by the same value to eliminate fraction denominators
- Cancel multiplied terms that are in the denominator

<u>Given</u>:
Juan has been saving for a new bike for two months. So far, he has saved $150 for the bike.
The money that he has saved so far is 30% of the cost of the bike.
We need to determine the total cost of the bike.
<u>Total cost of the bike:</u>
Let x denote the total cost of the bike.
The total cost of the bike is given by
The value of 30% can be written as
Thus, we get;
Multiplying both sides by , we have;
Simplifying, we have;
Thus, the value of x is 500.
Hence, the total cost of the bike is $500.
Answer: See explanation
Step-by-step explanation:
Let Amara money be represented by a
Since Candace has $15 more than Amar. Therefore, Candace money will be = a + 15
Their total money will be 85 and this can be represented in an equation as:
a + (a + 15) = 85.
a + a + 15 = 85
2a + 15 = 85
2a = 85 - 15
2a = 70
a = 35
Amar money = $35
Candace money = $35 + $15 = $50
