Answer:
The blank is 3
Step-by-step explanation:
1 - Give the blank a variable
x = our blank
2 - Write it out
3 - Get the denominators equal
4 - Simplify
5 - Solve for the numerators
30+7x = 51
-30 -30
7x = 21
x = 3
Answer:
Joseph has 175
Molly has 275
Step-by-step explanation:
y = 15x + 25
y = 25x + 25
You can put this into Desmos
Red is Joseph and Molly is blue
Molly - (10, 275)
Joseph - (10, 175)
x = the time
y = money over time

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,
w - width
6w - length
486 in² - area of the rectangle
(w)(6w) = 6w² - area of the rectangle
The equation:
6w² = 486 <em>divide both sides by 6</em>
w² = 81 → w = √81
w = 9 in
l = 6w → l = (6)(9) → l = 54 in
The perimeter: P = 2l + 2w
P = 2(54) + 2(9) = 108 + 18 = 126 in
<h3>Answer: The perimeter is 126in</h3>
