a) The numerator of fraction is 3 less than denominator. If 5 is subtracted from both numerator and denominator, the fraction becomes 4⁄5. Express the equation algebraically and upload your workout in the google classroom. b) What is the fractional number?
Answer: 17/20
Step-by-step explanation:
Let's define:
N = numerator
D = denominator.
The fraction is N/D.
We know that:
"The numerator of fraction is 3 less than denominator. "
N = D - 3
" If 5 is subtracted from both numerator and denominator, the fraction becomes 4⁄5."
(N - 5)/(D - 5) = 4/5.
Then we have a system of equations of two variables:
N = D - 3
(N - 5)/(D - 5) = 4/5.
The first step to solve this, is to replace the first equation into the second, in that way we can work with only one variable.
(D - 3 - 5)/(D - 5) = 4/5.
Now we can solve this for D.
(D - 8)/(D - 5) = 4/5
D - 8 = (D - 5)*(4/5) = (4/5)*D - 4
D - (4/5)*D = -4 + 8 = 4
(1/5)*D = 4
D = 4*5 = 20
And here we can use the first equation to find the value of N.
N = D - 3 = 20 - 3 = 17
Then our fraction is:
N/D = 17/20

Step-by-step explanation:
Evaluate b(x)=18−0.5x when x=−2,0, and 5.
hope that helps :))
The value of the function b(x) = 18 - 0.5x when x = -2, 0, and 5 are 19, 18 and 15.5 respectively.
What is equation?A formula known as an equation uses the equals sign to express how two expressions are equal.
Given function is b(x) = 18 - 0.5x
Putting x = (-2) in b(x) = 18 - 0.5x
b(x) = 18 - 0.5(-2)
b(x) = 18 - (-1)
b(x) = 18 + 1
b(x) = 19
Putting x = 0 in b(x) = 18 - 0.5x
b(x) = 18 - 0.5(0)
b(x) = 18
Putting x = 5 in b(x) = 18 - 0.5x
b(x) = 18 - 0.5(5)
b(x) = 18 - 2.5
b(x) = 15.5
Hence, required answers are 19, 18 and 15.5 respectively.

For f (x) =4x+7, find f(4)
Answer:
23
Step-by-step explanation:
If you have something that says it is the f(x) or just f(something) then that is just telling you what the x equals. In this case, x=4 so you plug that into the equation.
This gives you f(4)=4(4)+7. From here, you will use the order of operations to solve.
f(4)=4*4+7
f(4)=16+7

70+23x-5+110+14x=360 (please show step bc I need to turn in work-paper) Thank you!
x = 5
explanation
70 + 23x - 5 + 110 + 14x = 360
first you group the like terms
23x + 14x + 70 - 5 + 110 = 360
then combine the like terms
23x + 14x 70 - 5 + 110
37x + 175 = 360
subtract 175 from both sides
175 - 175 = 0 360 - 175 = 185
to get
37x = 185
divide both sides by 37
37x/37 = 0 185/37= 5
which gives you

Answer: 12.034 yards
Step-by-step explanation:
Given the following :
Height to which egg is protected = 11 meters
Converting this height of 11 meters to yards
Let the height in yards = h
1 meter = 1.094 yards
11 meters = h
(1 * h) = (11 * 1.094)
h = 12.034 yards
Hence, the height in yards to which egg is protected = 12.034 yards

Margaret works at a clothing store today she has only sold only shirts and pants the ratio of the number fours sold to the total number of items sold is 2/5 which model shows ratio ratio
Answer:
Step-by-step explanation:
The one with 2 shirts and 5 pants
The ratio of the two pieces of clothing is displayed as 2:3.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Given, Margaret is employed by a clothing retailer. She has just sold pants and shirts today. The proportion of shirts sold to all other things sold is 2/5. The model that displays this ratio
The ratio of shirts sold to total garments is 2:5 if the number of shirts sold is 2/5 of the total number of clothes sold.
Additionally, the ratio of sold shirts to sold pants is 2:3, meaning that three pants are sold for every two shirts.
For instance, 9 pairs of pants would be sold if 6 shirts were sold.
Therefore, 2:3 shows the ratio of the pair of pants and shirts.

what is the solution to
25+r = -5(2+8r)+6r
Step-by-step explanation:
25+r = -5(2+8r)+6r
25+r= -10-40r+6r
25+r= -10-34r
34r +r = -25-10
35r= -35
r= -35/35
r= -1
Answer:
[tex]\huge\boxed{r=-1}[/tex]
Step-by-step explanation:
To solve for this equation, our goal is to isolate the variable r on one side by reversing the equation.
We have the equation [tex]25 + r = -5(2+8r)+6r[/tex]. Let's simplify it.
Apply the distributive property on the right:
[tex]25 + r = (-5 \cdot 2) + (84 \cdot -5) + 6r\\\\25+r = -10 - 40r + 6r[/tex]
Combine like terms:
[tex]25 + r = -10 - 34r[/tex]
Add 34r to both sides:
[tex]25 + r + 34r = -10 - 34r + 34r\\\\25 + 35r = -10[/tex]
Add 10 to both sides:
[tex]25 + 35r + 10 = -10 + 10\\\\35 + 35r = 0[/tex]
Subtract 35 from both sides:
[tex]35 + 35r - 35 = 0 - 35\\\\35r = -35[/tex]
Divide both sides by 35:
[tex]35r \div 35 = -35 \div 35\\\\r = -1[/tex]

1/3 (q + 3) = 5
What is Q?
Explain why
1/3 is a fraction
Answer:
q=12.
Step-by-step explanation:
1/3(q+3)=5 can be translated to (q+3)/3=5.
Multiply each side by 3 to get q+3=15.
Subtract 3 from each side to get q=12.
Can you explain what you mean by "Explain why 1/3 is a fraction?"
Answer:
Assuming Q is q, q = 12. 1/3 is a fraction since it is a ratio of two whole numbers.
Step-by-step explanation:
For this problem, we need to understand two things. (1) q is the unknown variable of this equation. (2) The definition of a fraction is a "numerical quantity that is not a whole number" -Oxford Dictionary which can also be stated mathematically as a ratio of two whole numbers.
First, let's explain why 1/3 is a fraction. In the numerator, we have the whole number 1, and in the denominator, we have the whole number 3. Mathematically, 1/3 is a fraction since it is a ratio of two whole numbers. Alternatively, we can say it's a non-whole numerical quantity. In this case, 0.33 repeating.
Second, let's solve for our unknown variable q:
1/3 ( q + 3 ) = 5
1/3 ( q + 3 ) * 3 = 5 * 3
q + 3 = 5 * 3
q + 3 = 15
q + 3 - 3 = 15 - 3
q = 15 - 3
q = 12
Hence, the value of q is 12.

Write the slope-intercept form of the equation of the line through the given point with the
given slope.
through: (-1,0), slope = -2
Answer:
y = -2x - 2
Step-by-step explanation:
Slope intercept form of equation is y = mx + c
c is intercept and m is slope
given that slope is -2
m = -2
thus, equation in slope intercept will be
y = -2x + c
The given line passes through (-1,0)
y = -2x + c
lets substitute y = 0 and x = -1 in the given equation
0 = -2*-1 + c
0 = 2 + c
c = -2
Thus, the complete slope intercept equation after using the value of c as -2
we have
y = -2x - 2 answer
