Answer:
(6x + 2) feet
Step-by-step explanation:
The formula for the perimeter of a rectangle = 2L + 2 W
Where L = Length
W = Width
Hence, the:
The length of the pool was (2x -3) feet and the width of the pool was (x + 4) feet.
The perimeter of the rectangular pool =
2(2x - 3) + 2(x + 4)
= 4x - 6 + 2x + 8
= 4x + 2x - 6 + 8
= (6x + 2) feet
Therefore, an expression for the perimeter of the pool area to be fenced is (6x + 2) feet
The ratio of the number of cars to dolls in a toy store is 3/20 . The ratio of the number of male dolls to the number of female dolls is 3:5 There are 500 female dolls. How many toys are there?
Answer:
800 dolls
Step-by-step explanation:
Step one:
given data
we are told that the ratio of the number of male dolls to the number of female dolls is 3:5 , i.e male dolls to female dolls is 3 to 5
given that there are 500 female dolls, let the number of male dolls be x
Step two:
3/5= x/500
cross multiply we have
3*500=5x
1500=5x
divide both sides by 5
x=1500/5
x=300
hence there are 300 male dolls
The total dolls is 300+500= 800 dolls

Every day, Isabella practices the piano for 0.75 hour and the flute for 1.4 hours. What is the total number of hours that she practiced in April? (Reminder: April has 30 days
Answer:
She practiced a total of 64.5 hours
Step-by-step explanation:
Here, we need to know the number of hours practiced on both per day
Mathematically, that will be;
0.75 + 1.4 = 2.15 hours per day
So in 30 days ; the total number of hours will be
30 * 2.15 = 64.5 hours

Dimas is playing a game that uses a number cube. The sides of the cube are labeled from 1 to 6. Dimas wants to roll a 2 or 3. He rolls the number cube one time
Answer:
B. 1/3
Step-by-step explanation:
The total number of sides in the cube are 6 (1,2,3,4,5,6). If Dimas only wants to roll either a 2 or 3 then that would mean that he has 2 chances out of the total 6 probable outcomes to roll one of those numbers. Therefore, in order to find the probability of this happening in a single roll we need to divide the number of times that his two choices appear on the dice by the total number of sides the dice has, like so...
2 / 6 = x

Find the solution of this system of equations
x- 10y = -59
-4x + 10y = 86
Answer:
x - 10y = -59
(+)-4x + 10y = 86
-3x = 27
x = -9
substitute x into x - 10y = -59
-9 -10y = -59
-10y = -50
y = 5
Subtract the expressions: (5z + 4) - 5(-3z -6)
Hey there!
“(5z – 4) – 5(–3z – 6)”
DISTRIBUTE the RIGHT side of your equation
5z – 4 –5(–3z) + (–5)(–6)
–5(–3) = 15z
(–5)(–6) = 30
NEW EQUATION: 5z – 4 + 15z + 30
COMBINE your LIKE TERMS
(5z + 15z) + (4 + 30)
5z + 15z = 20z

The graph below shows a system of equations:
The x-coordinate of the solution to the system of equations is
Answer:
solution is (-2, 2) so x-coordinate of solution is -2
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
First, we have to write down both equations.
y = x + 4
3y = -2x + 2
Now we already have an equation that we can plug into the other equation.
= 3(x + 4) = -2x + 2
= 3x + 12 = -2x + 2
= 5x + 12 = 2
= 5x = -10
x = -2
Now we know that x = -2, and the question asks for the x-coordinate, which is -2.
Find the value of x that makes m || n
Answer:
a) 24
Step-by-step explanation:
To make m//n, the sum of co-interior angles (4x + 84) should be 180
4x + 84 = 180
4x = 180 - 84
4x = 96
x = 96/4
x = 24
