If a worker can do his job in 5 hours, and a student can do the same job in 8 hours, what part of the work is left to finish after two hours of work? NOTE: THEY WORKED TOGETHER
ANSWER: FRACTIOn
Answers
Answer:
Part of work left to finish after two work hours is 7/20
Step-by-step explanation:
Firstly, we need to calculate their joint work rate
That will be;
1/(1/5 + 1/8) = 1/(13/40) = 40/13
This means that they will complete the task in 40/13 hours
1 whole part takes 40/13
x part will take 2 hours
x * 40/13 = 2
40x = 26
x = 26/40
So the part that will be completed in two hours is 26/40
This means that the part left to complete will be:
1 - 26/40 = 14/40 = 7/20
Answer:
7/20
Step-by-step explanation:
you need to find what is left, not how much they did (which is 13/20)
Given f(x) = 5(x + 1) + 16, what is the value of x when f(x) = 1?
Answers
Answer:
x=26
Step-by-step explanation:
substitute x with 1: 5(1)+1+16
Answer:
x = -4
Step-by-step explanation:
The functional notation () simply means that you replace in the function with whatever values are in the domain. So () = 5 ( + 1) + 16 means that the solution set will contain the answer for every value of .
In the question, () = 1. So you set the function equal to 1, then solve for :
() = 1 = 5 ( + 1) + 16.
Add −16 to both sides: − 15 = 5 ( + 1)
Divide both sides by 5: − 3 = + 1
Add −1 to both sides: − 4 =

A line with a slope of -4 has a coordinate of (0,3). If the other coordinate is (6,t),
find the value of t. Plz show work
Answers
Answer:
Alrighty! So this is what we know:
Slope (m) = (-4)
Co-ordinate (0,3)
Co-ordinate 2 (6,t)
t = ?
Let's find our equation...
y=mx+b <-- just plug what we know in...
3=(-4)0+b
3=0+b
b=3
We just found b! woohoo
Now what is t? t is a value we need to know WHICH IS the y value of a co-ordinate that corresponds to when x is 6, as we know a co-ordinate is expressed as --> (x value, y value).
SO-
t=y
plug it in our equation...
y=mx+b
t=(-4)x+3
t=(-4)(6)+3
t=(-24)+3
t=(-21)
SOOOOOOOO WE HAVE OUR T!! just write a therefore statement like "therefore the value of t is -21." and you're set! hope this helped, any questions? ask in the comment section. :)

solve for z
−p⋅(51+z)=dz+84
Answers
Answer:
z≠0
Step-by-step explanation:
dz+84=-p(51+z)
dz+84-84=-p(51+z) -84
dz=-p(51+z) -84
dz/z=-p(51+z) /z-84/z
The value of z is (84 + 51p) / (d - p).
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
-p(51 + z) = dz + 84
Remove the parentheses.
-51p - pz = dz + 84
Subtract dz on both sides.
-51p - pz - dz = 84
Add -51p on both sides.
--pz - dz = 84 + 51p
z (-p + d) = 84 + 51p
z = (84 + 51p) / (d - p)
Thus,
The value of z is (84 + 51p) / (d - p).

In the coordinate plane, line p has a slope of 8 and y-intercept (0,3). What are the slope and y-intercept of line r?
Answers
Answer:
y = 8x + 3
Step-by-step explanation:
The line we are describing here is line p;
slope of line p = 8
y- intercept = (0,3)
y-intercept of a line is the point where it crosses the y-axis. At this point, the x = 0
So;
Slope of the line = 8
y-intercept = 3
Equation of the line;
y = mx + c
y and x are the coordinates
m is the slope
c is the y-intercept
y = 8x + 3

Step-by-step explanation:
The sum of all octogon's angles equals 1080°
Let's solve your equation step-by-step.
8(16x + 23) = 1080
Step 1: Simplify both sides of the equation.
8(16x + 23)=1080
(8)(16x) + (8)(23) = 1080(Distribute)
128x + 184 = 1080
Step 2: Subtract 184 from both sides.
128x + 184 − 184 = 1080 − 184
128x = 896
Step 3: Divide both sides by 128.
128x/128 = 896/128
x = 7°
