What is the value of x?
Enter your answer in the box.
Answer:
x=12
Step-by-step explanation:
Both Angles together have a 180 degrees, set your formula up as
180=(10x-20)+(6x+8)
180=10x+6x-20+8
180+20-8=16x
192=16x
192/16=x
12=x
Answer:
x = 12
Step-by-step explanation:
The two angles form a straight line so they add to 180
10x-20 + 6x+8 = 180
Combine like terms
16x -12 = 180
Add 12 to each side
16x-12+12=180+12
16x = 192
Divide each side by 16
16x/16 =192/16
x = 12
Jim orders prints from a website. The site charges him $6.95 a month and $0.04 for each print he orders.
Enter an equation that can be used to find the number of prints, P, Jim ordered last month if the website charged
him $17.79.
Enter the number of prints Jim ordered last month.
Answer:
271 prints.
Step-by-step explanation:
So to answer the question, we need to first write a formula to find the answer.
We know that the starting price per month is 6.95 dollars.
The full price is 17.79 dollars.
So we can start this off by writing:
17.79=6.95
Now, every time Jim prints, he charges 0.04 dollars. This will add to the orginal cost, which is 6.95. And remember this isnt a single payment, but a payment that varies depending on the amount of paper, p. So we can write this as:
17.79=6.95+0.04p
6.95 wont ever change, hense why it doesnt have a variable. 0.04 however, varies depending on the amount of paper, and thats why we included the variable p.
These two values combined make 17.79, hense why it is on the opposite side of the equals sign.
So, now we need to find how many papers, p, were printed.
To find this, lets just take our equation, and solve for P like an ordinary problem:
17.79=6.95+0.04p
So first off, lets subtract the 6.95 from both sides, because that iscolates the 0.04p, which contains the variable.
Now we have:
10.84=0.04p
Now, we could divide both sides by 0.04.
But remember, the whole point of doing this is to make 0.04p into 1p.
So another way of doing this is multiplying the 0.04 by 25, since 0.04*25=1.
So lets multiply both sides by 25:
10.84*25 is 271.
Since 10*25 is 250
And
.84*25 is 21.
So now we know:
271=1p
So 271 is your answer!
Hope this helps!
The equation that can be used to find the number of prints, p, is $17.79 = $6.95 + $0.04p and Jim ordered 271 prints last month.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We can write an equation to represent the total cost that Jim was charged by the website for last month's prints, p to represent the number of prints he ordered:
Total cost = Monthly fee + Cost per print x Number of prints
Using the values given in the problem:
$17.79 = $6.95 + $0.04p
To solve for p, one side of the equation. First, we can subtract $6.95 from both sides:
$10.84 = $0.04p
Then, we can divide both sides by $0.04:
p = 271

Find q
(7q-46)
(3q+6)
Answer:
[tex]q = 22[/tex]
Step-by-step explanation:
The angle measure of a straight line is (180) degrees As given in the picture, line (AC) is a straight line, thus its angle measure is (180) degrees. Angles (ABD) and (DBC) make up line (AC). Therefore, one can conclude that the sum of angles (ABD) and (DBC) is (180) degrees. Form an equation, simplify and use inverse operations to solve for the unknown parameter (q).
[tex](<ABD) + (<DBC) = (AC)[/tex]
Substitute for the angle measures,
[tex](7q-46)+(3q+6)=180[/tex]
Simplify,
[tex]10q-40=180[/tex]
Inverse operations,
[tex]10q-40=180\\\\10q = 220\\\\q = 22[/tex]

Figure A is a scale image of Figure B what is the value of x
Answer:
72
Step-by-step explanation:
20 got 4 added to it and the only number that gives you 24 when you multiply it is 4x6 and we can prove that to be right because the one before it is 4x5 and it gives us 20. Now that we know the multiplier is 5 and 6 we can ask ourselves, "What do I multiply by 5 that gives me 60?" And that is 12. So 12x6 is 72 for x.
10. It rained 375 inches in 15 hours. At this rate, how much will
it rain in 35 hours? Answer in decimal form.
Answer:
875
Step-by-step explanation:
375 divided by 15 =
25
25 times 35 =
875
Dividing 375 by 15 shows how much it rains per hour
Then times that by the number of hours to get your answer
Answer:
Step-by-step explanation:
Set this up as a proportion with the number of inches of rain on the top and the number of hours it rained on the bottom.
[tex]\frac{in.}{hrs}:\frac{375}{15}=\frac{x}{35}[/tex] and cross multiply to solve for x:
15x = 13125 so
x = 875 inches
Solve for x.

2. Priscilla is drawing a map of her school that uses a scale in which 1.5 cm 1 point
on the map represents 3 ft. If the first hallway has a length of 120 ft, what
should the length of the hallway be on the map?
O
a. 40 cm
b. 60 cm
C. 30 cm
d. 45 cm
Answer:
The answer is 60cm. (b)
Step-by-step explanation:
For every 1.5cm on the map, it represents 3 ft on real-size scale.
In other words, for every 1cm on the map, it represents 3/1.5 = 2ft on real size scale.
If you want to find 120ft of real-size scale, you can use 120ft/2ft * 1cm which gives 60cm

Hope this helps you. I apologize if it’s incorrect.
Answer:
x = 6/k
Step-by-step explanation:
kx + 12 = 3*kx
to make like terms on same side shift kx to right hand side . when u shift positive kx to other side it becomes negative
12 = 3kx - kx
12 = 2kx
shift 2 to left hand side when u shift multilication changes to division.
12/2 = kx
6 = kx
to find x u must shift k to other side . here also same since k and x are multilied when k shifts to others side it becomes divisor.
6/k = x

- Molecules in both the metal and the surrounding air will start moving at lower speeds.
- Molecules in both the metal and the surrounding air will start moving at higher speeds.
- The air molecules that are surrounding the metal will slow down, and the molecules in the metal will speed up.
- The air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down.

The inverse of the function f(x) = one-half x plus 10 is shown. h(x) = 2x- What is the missing value? 1 5 10 20
Answer:
20
h(x) = 2x - 20
Step-by-step explanation:
f(x) = ¹/₂ x + 10
First, isolate x, like so:
f(x) - 10 = ¹/₂ x
x = 2(f(x) - 10)
x = 2f(x) - 20
Now, simply switch f(x) with x and x with h(x), like so:
h(x) = 2x - 20

the answer is 20

Johanna buys two poster frames that have the same area, but different shapes. One is a rectangular frame with a width of 40 inches and a length of 30 inches. The other frame is square. What a poster with dimensions of 36 inches X 36 inches fit in the square frame?
Answer:
No, the poster would not fit in the frame
Step-by-step explanation:
A rectangle is a quadrilateral (has 4 sides and 4 angles) with two pair of opposite and equal sides.
A square is a quadrilateral in which all sides are equal.
Given that the rectangular frame has a width of 40 inches and a length of 30 inches. The area of the rectangular frame is:
Area of rectangular frame = length * breadth = 40 inches * 30 inches = 1200 in²
Since the square frame has the same area as the rectangular frame, hence:
Area of square frame = length * length
length² = 1200
length = √1200 = 34.64
Therefore the dimensions of the square frame is 34.64 inches by 34.64 inches.
Hence a poster with dimensions of 36 inches X 36 inches cannot fit in the square frame.
