Answer:
10.2
Step-by-step explanation:
20x=204
x=10.2
Answer:
x = 10.2
Step-by-step explanation:
To solve for x, we have to isolate it on one side of the = sign. The number on the other side is the value of x.
20x - 4 = 200
First, we can remove -4 from the equation. The inverse of -4 is +4, so we will add 4 to both sides. Adding 4 to -4 will neutralize it, making its value 0.
20x - 4 + 4 = 200 +4
Simplify this.
20x = 204
Now, we have 20 · x = 204. The inverse of multiplication is division. To the times 20, we will divide by 20 as well.
[tex]\frac{20x}{20}[/tex] = [tex]\frac{204}{20}[/tex]
Simplify.
x = 10.2
We can check this by substituting the value of x, 10.2, for the variable.
20(10.2) - 4 = 200
204 - 4 = 200
200 = 200
Since the equation is true, the answer must be 10.2.
I hope this helps ^^ Good luck
The ratio of pages read to minutes for Hang is 5:8. Select all the people who have a greater ratio of pages read to minutes than Hang.
Kira: 2 pages read every 4 minutes
Joe: 6 pages read every 9 minutes
Quon: 5 pages read every 7 minutes
Lulu: 10 pages read every 13 minutes
Lorenzo: 1 page read every 3 minutes
Answer:
Step-by-step explanation:
B, C, and D
By doing 5÷8 = .625 you know that Hang can read .625 of a page per minute.
You can do this for the rest of the people finding that Kira reads .5 page per minute which is a slower/ smaller ratio, Joe rate is .66, Quon's ratio is .71 and Lulus rate is .76, the only rate that is smaller than Hangs is Kira,s, leaving you with Joe, Quon, and Lulu to be your answer
Why do you think sum or difference formulas will be helpful with finding the exact
ues of uncommon angles?
Answer:
The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle. The angle sum identities take two different formulas: sin(A+B) = sinAcosB + cosAsinB. cos(A+B) = cosAcosB − sinAsinB. The difference formula for cosines states that the cosine of the difference of two angles equals the product of the cosines of the angles plus the product of the sines of the angles. The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle.

Solve for y.
- 12 = 6y +18-9y
Answer:
[tex] \boxed{y = 10} [/tex]
Step-by-step explanation:
-12 = 6y + 18 – 9y
[Group like terms 6y and -9y]
-12 = (6y – 9y) + 18
[Simplify the expression]
-12 = -3y + 18
[Subtract 18 from both sides, subtraction property of equality, to isolate the variable and the value]
-12 = -3y + 18
–18 –18
-30 = -3y
[Divide by -3 from both sides, division property of equality, to get the variable y by itself]
-30 = -3y
÷(-3) ÷(-3)
10 = y
[Symmetric property of equality, if b = a, then a = b]
y = 10

Katya treated everyone in theater to a pizza party. She bought 12 pizzas and six 2-liters of soda. The bill was $137.64 (before tax). The night before, Katya had bought one pizza and one 2-liter of soda for her family, and the bill was $11.95 (before tax). How much was each pizza? How much was each 2-liter of soda?
Let x = the cost of each pizza in dollars
Let y = the cost of each 2-liter of soda (in dollars)
Cost of pizza:
Cost of 2-liter:
I need help with this word problem ASAP. Show work if possible! :)
let the price of pizza and soda( per 2 litre bottle) be x and y
from 1st condition
12x+2y=137.6.....(1)
from 2nd condition
x+y =11.95.......(2)
multiply eq. (2) by 2
2x+2y=23.9.....(3)
subtracting (1) and (3)
12x+2y=137.6
2x+2y= 23.9
10x = 113.7
x=113.7/10
x=11.37
2(11.37)+2y=23.9
22.74+2y=23.9
2y=23.9-22.7
2y=1.2
y=0.6
So the prices of the pizza and soda are 11.37 and 0.6 dollars.
Each pizza costs approximately $10.99, and each 2-liter of soda costs approximately $0.96.
Let x be the cost of one pizza, and y be the cost of one 2-liter of soda.
According to the information given, we can write the following two equations:
1. For the pizza and soda purchased for the theater party:
12x + 6y = 137.64
2. For the pizza and soda purchased for Katya's family:
1x + 1y = 11.95
Now, we have a system of two equations with two variables. We can solve it to find the values of x and y.
First, let's solve the second equation for y:
y = 11.95 - x
Next, substitute this value of y into the first equation:
12x + 6(11.95 - x) = 137.64
Now, simplify and solve for x:
12x + 71.7 - 6x = 137.64
Combine like terms:
6x + 71.7 = 137.64
Subtract 71.7 from both sides:
6x = 65.94
Finally, divide by 6:
x = 65.94 / 6
x ≈ 10.99
Now that we have the value of x, which is the cost of one pizza, we can find the cost of one 2-liter of soda using the second equation:
y = 11.95 - x
y ≈ 11.95 - 10.99
y ≈ 0.96
So, each pizza costs approximately $10.99, and each 2-liter of soda costs approximately $0.96.

A rectangular field is 36
meters long and 15 meters
wide How many more meters
18 it to walk on the sidewalk
rother than cutting through
the field diagonally?
Answer:
12meters
Step-by-step explanation:
Given data
Lenght = 36 meters
Width = 15 meters
The dimension of the diagonal can be gotten via Pythagoras theorem
D^2= L^2+W^2
Substitute
D^2= 36^2+ 15^2
D^2= 1296+225
D^2= 1521
D= √1521
D= 39 meters
Hence the distance while walking on the side is
=36+15
=51 meters
Hence the difference is
=51-39
=12meters

Carrie will spin the arrow on the spinner four times. What is the probability that the arrow will stop on A, then B, then C, Then D?
Answer:
1 / 256
Step-by-step explanation:
Sample space Total sections of spinner = (A, B, C, D) = 4
P(spinner stops on A) = 1 /4
Second spin :
P(stops on B) = 1/4
Third spin :
P(stops on C) = 1/4
Fourth spin :
P(stops on D) = 1/4
Hence,
P(A then B then C then D)

8(e)^2x+1=4
Answer:
A
Step-by-step explanation:
hello :
8(e)^2x+1=4
(e)^2x+1=4/8 = 1/2
so : 2x+1 = ln(1/2)
2x = ln(1/2) - 1
x = (ln(1/2) - 1)/2
The solution to the given exponential function is x = [ ln(0.5) - 1]/2
Solving exponential equationsThe standard exponential equation is expressed as y = ab^x
Given the expression
8(e)^2x+1=4
Divide both sides by 8
(e)^2x+1=4/8
(e)^2x+1 = 1/2
Take the ln of both sides
ln(e)^2x+1 ln(1/2)
2x + 1 = ln(0.5)
2x = ln(0.5) - 1
x = [ ln(0.5) - 1]/2
Hence the solution to the given exponential function is x = [ ln(0.5) - 1]/2
