2 equal expressions for 13(4 + x):
52 + x
4(13 + x)
explanation: to distribute the 13 to the terms inside the parentheses, you simply multiply 13 by 4, and then 13 by x. this will then give you 52, and 13x.
2. another equal expression with commutative property of addition:
52 + x
x + 52
Need ASAP! Will mark branliest ..What is the slope (m)? 2x+2y=8
Answer:
m= 1
Step-by-step explanation:
subtract 2x
2y= 2x + 8
divide by 2
y= x + 4
y= mx + b, m is the slope
Answer:
y = -x + 4
m= -1
Step-by-step explanation:
First thing you need to do is get y by itself so you can have it in y=mx+b format
2x + 2y = 8
2y = -2x + 8 divide by 2
y = -x + 4
since x is by itself there is an imaginary 1 in front of the x, so it would be -1

30 minutes into 3 feet per minute
Answer:
This is how you convert
Step-by-step explanation:
Feet per minute is speed unit, symbol: [fpm]. Definition of 1 feet per minute ≡ 1 ft / 60 s = 30.48 cm / 60 s. The speed with which the body moves 1 foot (or 30.48 centimetres) in 1 minute.. Compared to metre per second, feet per minute is smaller unit.
The length of a bridge is 170 m. The length of each of Robert's paces is 60 cm. What is the minimum number of full paces that it would take Robert to walk the full length of the bridge?
Answer:
283
Step-by-step explanation:
Given the following data;
Length of bridge = 170m
Robert's paces = 60cm to meters = 60/100 = 0.6m
Number of paces (P) required to cover the full length of the bridge is;
P = 170/0.6
P = 283.33 ≈ 283
Therefore, the minimum number of full paces that it would take Robert to walk the full length of the bridge is 283.

Step-by-step explanation:
One number is 16 more than another number. The two numbers have a sum of 120. Wbich system of equations could you use to find the two numbers
Step-by-step explanation:
Let, 1st number be x and 2nd number be y
Then,
equation 1
x = 16+y
equation 2
x + y = 120
or, y = 120 - x
now,
x = 16 + y
or, x= 16 + 120 - x (putting the value of y from equation 2 )
or, x + x = 136
or, 2x =136
or, x= 136/2
or, x =68
Then,
y = 120-x
or, y= 120- 68 (putting the value of x)
or, y= 52
Hence, the two numbers are 68 and 52.

1. find the value of x given the figure bellow. round your answer to the nearest tenth.
Answer:
Since the shape is an corresponding angle, you would work out the question like this:
(3x + 22) = (x + 30)
X = 4
Therefore X is equal to 4. No rounding is needed.

A Dinner Theatre actress is paid $250 per day to rehearse the play and
$500 per day to perform in front of an audience. In one season, an
actress earned between $2000 and $5000.
Write a system of inequalities
Graph it
And give two points
Answer:
See below
Step-by-step explanation:
Let the number of days the actress rehearse d the play be x and the number of days she performed in front of an audience.
Then she earned:
250x + 500yThe inequalities as per minimum and maximum amount the actress earned:
250x + 500y > 2000 ⇒ x + 2y > 8and250x + 500y < 5000 ⇒ x + 2y < 20So the system is:
x + 2y > 8x + 2y < 20The graph is attached, shaded region in the middle is the solution area.
The two points shown on the graph: (5, 5) and (8, 4)

You have 50 ft of fencing and want to fence in a rectangular area of 144 ft^2. What are going to
be the dimensions of the rectangular area?
Quadratic equation
Answer:
16 by 9 feet.
Step-by-step explanation:
We have 50 feet of fencing in total.
Therefore, the perimeter of our area is 50. Perimeter is given by:
[tex]P=2(\ell+w)[/tex]
Substituting 50 for P yields:
[tex]50=2(\ell+w)[/tex]
And dividing both sides by 2 yields:
[tex]\ell+w=25[/tex]
The area of a rectangular is given by:
[tex]A=\ell w[/tex]
Where [tex]\ell[/tex] is the length and [tex]w[/tex] is the width.
We want to enclose 144 feet squared. So, A=144:
[tex]144=\ell w[/tex]
By the perimeter equation, we can subtract a variable, say [tex]\ell[/tex] from both sides. Hence:
[tex]w=25-\ell[/tex]
Now, we can substitute this into our area equation. Therefore:
[tex]144=\ell(25-\ell)[/tex]
Distribute:
[tex]144=25\ell-\ell^2[/tex]
Subtract 144 from both sides:
[tex]-\ell^2+25\ell-144=0[/tex]
Divide everything by -1:
[tex]\ell^2-25\ell +144=0[/tex]
Factor:
[tex](\ell-9)(\ell-16)=0[/tex]
Zero Product Property:
[tex]\ell_1=9\text{ or } \ell_2=16[/tex]
Then it follows that:
[tex]w_1=25-(\ell_1)=25-9=16[/tex]
Or:
[tex]w_2=25-(\ell_2)=25-(16)=9[/tex]
Regardless, the dimensions of the rectangular area will be 16 by 9 feet.
Answer:
p = 2(l +w)
l= p÷2 -w = l= 25 -w
A= l x w =( 25 -W)W= 144
-w^2 +25w-144 =0
-w^2 +9w+16w- 144=0
(-w^2+9w) +(16w- 144) =0
-w(w - 9) + 16(w - 9) =0
(-w +16) = 0 or w - 9 =0
w = 9 or w = 16
so l = 25 - 9 = 16
or l = 25 - 16 = 9
therefore l = 16ft and w= 9ft

Answer:
scale factor - stretch by 6
Step-by-step explanation:
Answer:
1/3
Step-by-step explanation:
Look at two corresponding lengths that are easy to measure.
BC and B'C' are both along horizontal lines, so you can easily count squares to find their lengths.
BC = 3
B'C' = 1
B'C' is the image, and BC is the original.
The scale factor is obtained by dividing a length of the image by the corresponding length of the original.
scale factor = B'C'/BC = 1/3
Answer: 1/3

12. 8.25cm
Answer:
10. 30km
11. 288km
12. 99km
Step-by-step explanation:
If 1cm=12km, just take the amount of cm and multiply by 12km.
For example, 2.5x12=30, and 24x12=288.

Step-by-step explanation:
Step 1: Define
4x - 12 ≤ 16 + 8x
Step 2: Solve for x
Subtract 4x on both sides: -12 ≤ 16 + 4xSubtract 16 on both sides: -28 ≤ 4xDivide 4 on both sides: -7 ≤ xRewrite: x ≥ -7Here we see that any value x greater than or equal to -7 would work as a solution to the inequality.
∴ our answer is -7.
What is the range of this function?
A) {y | y > 0}
B) {y | y ≥ 0}
C) {y | y ≥ 3}
D) {y | y ≥ -3}
Greetings.
The range is the set of y-value.
The range starts from the minimum point to maximum point.
Our minimum point starts at 0 and maximum point starts less than infinity.
Therefore the range is 0<=y<+inf
However, we do not often write that, although it is right.
Therefore we write as y≥0
Thus, the answer is B choice.

What is the measure of angle X?
Enter your answer in the box.
M
Answer:
x = 47
Step-by-step explanation:
Every triangle's interior angles add up to 180°.
Let's make an equation.
x + 102 + 31 = 180
x + 133 = 180
x = 47
Answer:
X = 47 degrees
Step-by-step explanation:
The reason is because the total degrees in a triangle is 180 and 102 + 31 is equal to 133 degrees which then you take and subtract it from 180 which gives you 47 degrees.
