Diego is building a patio deck. The length of the deck is (x + 8) feet. The width of the deck is (x + 3) feet. What is the simplest form expression for the perimeter of the deck?
Answer:
(4x + 22) feet
Step-by-step explanation:
Diego is building a patio deck. The length of the deck is (x + 8) feet. The width of the deck is (x + 3) feet. What is the simplest form expression for the perimeter of the deck?
A patio deck = Rectangular in shape
Hence:
The formula for the Perimeter of a rectangle = 2L + 2W
Where
L = Length
W = Width
The length of the deck is (x + 8) feet. The width of the deck is (x + 3) feet.
The perimeter of the deck =
2(x + 8)feet + 2(x + 3)feet
= (2x + 16) feet +( 2x + 6)feet
= (2x + 2x + 16 + 6) feet
= (4x + 22) feet
Therefore, the perimeter of the deck = (4x + 22) feet

Answer: Choice (2) 3x-1 = 2x+3===============================================
Explanation:
We will plug x = 7 into each equation or inequality given to us. Then we determine if we get a true statement or not.
----------------
Let's start with choice (1)
x + 3 > 6
7 + 3 > 6 .... x is replaced with 7
10 > 6
Since 10 is larger than 6, this makes the last inequality true. Therefore, the first inequality is true when x = 7. So we can rule out choice (1) since we are looking for a false statement.
----------------
Move onto choice (2)
3x-1 = 2x+3
3*7-1 = 2*7+3 ... replace every x with 7
21-1 = 14+3
20 = 17
This is false since we don't get the same number on each side. Therefore, choice (2) is the final answer.
----------------
Since we found the answer, we can stop here. But let's keep going to check the others.
choice (3)
2(x+1) = x+9
2*(7+1) = 7+9 ... plug in x = 7
2*(8) = 16
16 = 16
We get the same thing on both sides, so the equation is true. We can rule out choice (3).
-----------------
Now onto choice (4)
[tex]-2x + 10 \le 0\\\\-2*7 + 10 \le 0\\\\-14 + 10 \le 0\\\\-4 \le 0\\\\[/tex]
This is true since -4 is to the left of 0 on the number line, which makes -4 smaller than 0. We can rule out choice (4).

2/1
Answer:
1/2
Step-by-step explanation:
you the x and the y intercepts!
the X intercept is (4,0) and the Y intercept is (0,-2)
and in having those two intercepts, it made solving for the slope a whole lot easier!!!
heres what you do:
-2 - 0 = -2
0 - 4 = -4
and that can be simplified down to 1/2 :D

1 - 0.75b
75b
0.25b
B - 0.75b
Answer:
try b-0.75b
Step-by-step explanation:
Cost of the bag after the discount is given by the equation A = B - 0.75B
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of the bag be represented as B
Now , the equation will be
The discount percentage of the bag is = 75 %
So , the cost of the bag after discount = cost of the bag - ( cost of the bag x discount percentage )
Substituting the values in the equation , we get
The cost of the bag after discount = B - ( 75/100 ) B
On simplifying the equation , we get
The cost of the bag after discount = B - 0.75B
Hence , the equation is B - 0.75B

How far along a motorway would you travel if you drove at 70 mph for 4 hours
Answer:
280 miles
Step-by-step explanation:
in one hour, you would travel 70 miles because you are going at the speed of 70mph
so to find out how far you go in 4 hours you would multiply 70(mph)×4(hrs) which would be?
280 miles

If I owe you $1.76 in overtime pay, you receive $19.50 for each hour of OT. How many hours overtime are you owed?
Answer: 0.09 hours
Step-by-step explanation:
You are owed $1.76 in overtime pay.
The hourly rate for overtime is $19.50 per hour.
To find the number of hours owed, you need to divide the amount owed by the amount owed per hour.
The number of hours you are owed is therefore:
= Amount owed / Amount owed per hour
= 1.76 / 19.50
= 0.09 hours
