Answer:
length= 35 feet and width= 10 feet
Step-by-step explanation:
You are given the perimeter of the rectangular deck is
90 feet.
2 x length + 2 x width = 90 You are also given that the deck's length is 5 feet less than 4 times it's width. That is length = 4 x width - 5
Those two equations are your system of linear equations. The second equation can be plugged into the first equation. This gives us an equation entirely in terms of width.
2x (4 x width - 5) + 2 x width =90
Distribute the 2 though
8 x width - 10 + 2 x width = 90
Combine like terms with width.
10 x width - 10 = 90
Add 10 to both sides.
10 x width = 100
Divide both sides by 10 width = 100
Now you can plug width into your original equation for length above. Recall: length = 4 x width - 5
Length = 4 x 10 - 5
Length = 40 - 5
Length = 35

How do you write (4)(25)-300 as an addition equation
Answers
(4)(25) - 300 can be written as an addition equation: 100 + (-300).
What is an equation?An equation is a pair of algebraic equations with the equal sign (=) in the middle and the same value.
Given:
An equation is (4)(25)-300.
To write (4)(25)-300 as an addition equation,
we can break it down into two separate addition equations as follows:
(4)(25) - 300 = (4)(25) + (-300)
To solve this further,
substitute the value 25 x 4 = 100 to the above equation, we get,
= 100 + (-300)
Therefore, the equation in the required form is 100 + (-300).

Mikey's family is taking a road trip. Their car can travel no more than 260 miles without needing to refill the gas tank. They have traveled 112 miles since they last filled the gas tank.
Mikey knows that the inequality representing this situation is 112 + x ≤ 260.
Select from the drop-down menu to correctly interpret the solution of this inequality.
Mikey's family can drive_____more miles before they need to refill the gas tank.
A. at most 148
B. at least 148
C. more than 372
D. more than 372
Answers
Answer:
A
Step by step:
you subtract 112 from 260 to isolate the variable. Then you get x is less than or equal to 148. Which means that the most miles that can be traveled is 148 miles before filling up.
Mikey's family can drive at most 148 more miles before they need to refill the gas tank. which is the correct answer would be option (A).
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
As per the given situation, the required inequality would be as
⇒ 112 + x ≤ 260
To isolate the variable, remove 112 from 260. The result is that x is less than or equal to 148.
⇒ 112 + x - 112 ≤ 260 - 112
⇒ x ≤ 148
This indicates that the maximum distance that may be traveled before filling up is 148 miles.
Therefore, his family can drive at most 148 more miles before they need to refill the gas tank.

A band earns $\frac{2}{3}$
of their profit from selling concert tickets and $\frac{1}{5}$
of their profit from selling merchandise. The band earns $1500 from selling concert tickets. How much money does the band earn from selling merchandise?
Answers
Dividing 2/3 profit of selling concert tickets by 1/5 profit from selling band mechandise.
(2/3) / (1/5) = 10/3 = 3 1/3
Hence band members make 3 1/3 or 10/3 times more profit from ticket sales than from band merchandise sales.
This can be elaborate in such a way also.
Let suppose the total profit is $30.
then the profit from the ticket sale = 2/3 of 30 = $20
and the profit from the band merchandise sales = 1/5 of 30 = $6
Now dividing 20 by 6, which gives 10/3. the same answer that were calculated above.

Brandon buys a radio for $48.81 in a state where the sales tax is 7%.
can someone pls help?
Answers
Answer:
$48.81 x 0.07 = 3.4167
$48.81 + $3.4167 = $52.2267
$52.23
Step-by-step explanation:
The shirt cost $48.81, and the sales tax is 7%. First convert the 7% into a decimal and you get 0.07, and then multiply that to the $48.81. You get left with $3.4167 and then add that to the $48.81 to get $52.2267. But, you have to shorten the numbers to make it look like money by simplifing. So the total is $52.23.
