Answer:
The value of x is -1.
Step-by-step explanation:
Simple equation:
☆Let's solve!
[tex]15 = - 5x + 10 \\ \frac{ - 10 = \: \: \: \: \: \: \: \: - 10}{ \frac{5}{ - 5} = \frac{ - 5x}{ - 5} } \\ x = - 1[/tex]
Answer:
x = -1
Step-by-step explanation:
15 = -5x + 10
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operations, and =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, subtract 10 from both sides of the equation:
15 (-10) = -5x + 10 (-10)
15 - 10 = -5x
-5x = 15 - 10
-5x = 5
Next, fully isolate the x by dividing -5 from both sides:
(-5x)/-5 = (5)/-5
x = -(5/5)
x = -1
-1 is your answer for x.

Answer:
60ft
Step-by-step explanation:
Using the formula shown a^2 + b^2 = c^2
5 ^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2
Take the square root of both sides:
C = 13
In the triangle below,
x= [ ? ]°. Round to the nearest
tenth.
Answer:
X = 38.7°
Step-by-step explanation:
Reference angle = x
Opposite side length = 8 cm
Adjacent side length = 10 cm
Applying trigonometric ratio formula, we have:
[tex] tan(x) = \frac{8}{10} [/tex]
[tex] x = tan^{-1}(\frac{8}{10}) [/tex]
[tex] x = 38.7 [/tex]
x = 38.7° (to the nearest tenth)
What is an angle that is supplementary to AGF?
Answer:
CGD I believe.
Step-by-step explanation:
9514 1404 393
Answer:
∠AGC or ∠FGD
Step-by-step explanation:
∠AGF is part of two linear pairs. The other angle in the pair is supplementary to ∠AGF.
Point G is on line AD, so ∠FGD is a supplementary angle to ∠AGF.
Point G is on line FC, so ∠AGC is a supplementary angle to ∠AGF.

If she sells 36 movie posters, how many band posters should she sell? Complete the explanation to find out how many band posters she should sell. Her current ratio of movie posters to band posters is 90:50. If she sells 36 movie posters, she will have 90 54 left. so she should sell band posters. 50 as
Answer:nm
Step-by-step explanation:
Researchers planning a study of the reading ability of third-grade children want to obtain a 95% confidence interval for the population mean score on a reading test, with margin of error no greater than 3 points. They carry out a small pilot study to estimate the variability of test scores. Assume the population standard deviation to be 12 points.
a. The study budget will allow as many as 100 students. Calculate the margin of error of the 99% confidence interval for the population mean based on n = 100.
b. There are many other demands on the research budget. If all of the various demands are met, there would be funds to measure only 10 children. What is the margin of error of the confidence interval based on n = 10 measurements?
c. Find the smallest value of n that would satisfy the goal of a 95% confidence interval with margin of error 3 or less. Is this sample size within the limits of the budget?
Answer:
A) M = 3.016
B) M = 9.79
C) 62
Step-by-step explanation:
A) We are given;
Population size; n = 100
standard deviation; σ = 12
Formula for the margins of error is;
M = z × σ/√n
At 99% confidence interval, z = 2.58
Thus;
M = 2.58 × 12/√100
M = 3.016
B) n is now equal to 10, thus at same confidence interval used in option A, we have;
M = 2.58 × 12/√10
M = 9.79
C) to solve this, we will use the formula;
n ≥ (zσ/m)²
Where;
z at 95% confidence interval has a value of 1.96
m is the margin of error = 3
Thus;
n ≥ (1.96 × 12/3)²
n ≥ 61.4656
Thus,approximately n = 62
A swimming pool has a leak and is losing 23.5 gallons of water every 5 days. What is the average change in water volume each day?
Step-by-step explanation:
If you divide the distance by the elapsed time, the result will be the rate of water loss (evaporation). To convert this evaporation rate in to gallons lost over a specific time period, you will need convert the measure into a volume. WTG GLAD U GOT IT RIGHT..
Help plzzzz I need it
Answer:
D
Step-by-step explanation:
The answer is D because when you look at an ordered pair it is (x , y) the x stands for x-axis and y for y-axis. The x numbers are the ones on the bottom line going horizontally across your screen and the y numbers are the ones on the left side of the graph going up and down. Therefore when you are looking at (1.5 , 9) you start on the bottom line and go to 1.5 then go strait up to 9 on the line on the left and thats where the point is! Hope this helps, let me know if somthing doesn't make sense!

Answer:
One 8x10 photo costs $1.50.
Step-by-step explanation:
You can write two equations and use a system of equations.
Let w = price of 1 wallet-size photo.
Let n = price of 1 of 8x10 photo.
Basic package:
24w + n = 19.5
Deluxe package:
32w + 3n = 28.5
We have a system of equations:
24w + n = 19.5
32w + 3n = 28.5
Multiply both sides of the first equation by -3.
Rewrite the second equation below it and add the equations.
-72w - 3w = -58.5
(+) 32w + 3n = 28.5
---------------------------------
-40w = -30
w = -30 / -40
w = 0.75
24w + n = 19.5
24(0.75) + n = 19.5
18 + n = 19.5
n = 1.5
Answer: One 8x10 photo costs $1.50.

Find the value of the parallelogram. The value of x is _?
Answer:
x is 115
Step-by-step explanation:
Because since one side of the square is 65 you add another 65 to the opposite side since there parrel to get 130, then you subtract 130 from 360 to get 230; finally you divide 230 by 2 and have 115 as your answer for x

Answer:
108° or Red
Step-by-step explanation:
This looks closest to a 108° angle.
108 - 7 = 101
101 ÷ 5 = 23
x = 23
Do the simple math for the rest of the angles...
Here is the math from where that leaves you...
127° (b) + 90° (d) + 136° (e) + 79° (a) + 108° (c) = 540°
P.S.
Rectangle answer must be 360° because 90° × 4 = 360°
Any additional vertices equals another 180° to the final number.

Six children are sharing 4 pizzas. Each child
should have the same amount of pizza. How
much pizza can each child have?
Hey there!
The answer to your question is each child should have 2/3 of a piece of pizza.
If there are 4 pizzas, we divide them among the children, so: 4/6
Simplified, 4/6 is 2/3, so 2/3 is the answer.
