Answer 1

Answer:

x = 4

Step-by-step explanation:

First you would add those 2 equations, which would be 43x + 8. Then you make it equal to 180, so 43x + 8 = 180. Subtract 8 from both sides, and divide 43 from both sides.

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)

What kind of Function is this y=x2-3x-4?

Answers

A liner one function

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. :)

Brian drinks tea at an incredable rate he drinks 3 1/2 liters of tea every 2/3 of an hour . Ben drinks at a constant rate how many liters of tea does he drink in one hour

Answers

Answer:

5 1/2 liters of tea

Step-by-step explanation:

Brian drinks tea at an incredable rate he drinks 3 1/2 liters of tea every 2/3 of an hour . Ben drinks at a constant rate how many liters of tea does he drink in one hour

3 1/2 =>7/2 => 2/3 hour

Hence:

2/3 hour = 7/2 liters

1 hour = x

Cross Multiply

2/3 x = 1 × 7/2

x = 7/2 ÷ 2/3

x = 7/2 × 3/2

x = 21/4

x = 5 1/4 liters

Hence, Brian drinks 5 1/4 liters in 1 hour

What is the difference of the values of the two variables in this system of equations?
y= 2x + 1
x + 3y = 10

Α. 0

B. 1

C. 2

D. 3

Answers

a is your answer to this

Answer: C

Step-by-step explanation: y = 2x + 1, x + 3y = 10 in these two equations you can put y = 2x + 1 in 3y in x + 3y = 10 so it would be x + 3(2x + 1) = 10,

x + 6x + 3 = 10, 7x = 7 so x = 1 and when we put the value of x in y = 2x + 1, it would be y = 2(1) + 1 so y = 3. difference would be 3 - 1 = 2 so it is C

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 =

Answer:

x = 7°

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°
