The perimeter of the surface of a workbook is 40 inches. The workbook is 11 inches tall. How wide is it?
Answer:
9 inches
Step-by-step explanation:
11 times two for the two equal sides is 22. 40-22 equals 18. 18 is the sum of the other two sides so you divide by two. 18/2 equals 9, so 9 inches.

Literal equations solve for y. 3x+4y=-4
Answer:
y = - 1 - 3/4x
Step-by-step explanation:
Step 1:
3x + 4y = - 4 Equation
Step 2:
4y = - 4 - 3x Subtract 3x on both sides
Step 3:
y = - 4 ÷ 4 - 3x ÷ 4 Divide by 4 on both sides
Answer:
y = - 1 - 3/4x
Hope This Helps :)
Answer:
y=-1
Step-by-step explanation: 3x+4y=-4 so in this you have to isolate the y so you move 3x to the right by subtracting 3x from both sides. Your equation will then turn into 4y=-4-3x. Then you divide both sides by 4. y=-1 ,-3/4x

Which expression is equivalent to 3/8 + 4/8
Question on a picture
Answer:
x = 5
Step-by-step explanation:
Given
- 160 = - 4(7x + 5) ← divide both sides by - 4
40 = 7x + 5 ( subtract 5 from both sides )
35 = 7x ( divide both sides by 7 )
5 = x
Write 5.4 as a mixed number and as an improper fraction.
Write your answer in simplest form.
Answer:
27 over 5 improper fraction
5 whole number 2 over 55 mixed
Do you want to know how to write the decimal number 5.4 as a fraction?
Here we will show you step-by-step how to convert 5.4 so you can write it as a fraction.
You can take any number, such as 5.4, and write a 1 as the denominator to make it a fraction and keep the same value, like this:
5.4 / 1
To get rid of the decimal point in the numerator, we count the numbers after the decimal in 5.4, and multiply the numerator and denominator by 10 if it is 1 number, 100 if it is 2 numbers, 1000 if it is 3 numbers, and so on.
Therefore, in this case we multiply the numerator and denominator by 10 to get the following fraction:
54 / 10
Then, we need to divide the numerator and denominator by the greatest common divisor (GCD) to simplify the fraction.
The GCD of 54 and 10 is 2. When we divide the numerator and denominator by 2, we get the following:
27 / 5
Therefore, 5.4 as a fraction is as follows:
27 / 5

The fish population in a local lake is 10,000. The population increase by half every year. Which function represents the fish population after x years?
1. f(x) = 1.5(10,000)^x
2. 10,000(-1.5)^x
3. None
4. f(x) = 10,000(0.5)^x
5. f(x) = 10,000 (1.5)^x
Answer:
5. f(x) = 10,000 (1.5)^x
Step-by-step explanation:
We would have to multiply the original amount by 1.50^x because the initial amount would be 1, and 50% increase would be .5 so 1.5 and you raise it to the number of years to show the total increase.
Let's test it.
Initial:
10,000
After 1 year
10,000 + (.5*10000)
10,000 + 5000 = 15,000
After 2 years
15,000 + (.5*15000)
15,000 + 7500 = 22,500
Let's try our equation.
f(x) = 10,000 (1.5)^x
x = 2
10,000(1.5)^2
10,000(2.25) = 22,500
The same!
Choose the slope and y-intercept that correspond with the graph.
Answer:
Slope=3
y-intercept=4
Step-by-step explanation:
the line intercepts the y axis at 4.
Answer:
slope = 3
y-intercept = 4
Step-by-step explanation:
From the graph, we can automatically tell that the y-intercept is at (0,4) so the y-intercept is 4. Now, we just need to find the slope and to do that we can choose 2 points. I am choosing (-2,-2) and (0,4).
The slope formula is m = y2-y1/x2-x1. I am going to plug in the points in the formula.
m = (4 - (-2))/(0 - (-2))
m = 6/2
m = 3
slope = 3
y-intercept = 4

What is the slope-intercept equation of the line below?
Answer:
We need more information, but the equation is y=(slope)x+(y-intercept). If you can find two points on the line, and the y-intercept, you've got your equation.
Step-by-step explanation:
To find the slope, you need two points. Then you take the y-value of the second point minus the y-value of the first point and divide that by the x-value of the second point minus the x-value of the first. If the y-intercept is not given, you need to plug in the equation, making x=0, and then solve for b, also known as the y-intercept. Hope this helps! Feel free to let me know if this is not clear.
