A machine produces 75 widgets an hour. How many widgets does it produce in 6 minutes

Answers

75 divided by 60 times 6 equal 7.5

7widgets would be made in 6 minutes. Because there are 60 min in 1 hour, so 10 6 min spans in 1 hour, so 75/10=7.5 however you don't make half a widget and call it a full one so 7 every 6 min.

Solve for x. (Round to the nearest thousandth.)
3x - 8 = 15

Answers

Answer:x = 7.667

Step-by-step explanation:

3x - 8 = 15

+ 8 = 23

3x = 23

divide 3 by 3 and 23 so you get x by itself

answer = 7.667

Answer:

x = 7.667

Step-by-step explanation:

3x - 8 = 15 (Rearrange expression)

-8 - 15 = -3x (Combine like terms)

-23 = -3x (Divide)

x = 7.667

Solve the equation
40=5(d - 2)

-2(x - 9)= -24

Answers

40=5d-10
first, you have to multiply 5 by D and-2 and then , you will get 40=5d-10
then you will combine like terms, like 40+10=5d
then you will get 50=5d and you divide 50 by 5 to get D only, and finally, you will get D=10.
the final answer is D=10

second question,
all you have to do is multiply-2 by x and -9
and then you get -2x+18=-24
then, you have to combine like terms like I did on the first one, which is -2x= -24-18 and then, you will get -2x=-42 and you have to divide 2 by -42 which is x=21
the final answer is x=21.

I am pre sure that it helped you. text me on messages on brainy if you have any questions that you want to ask me.

40 = 5(d - 2)
Then distribute the 5.
40 = 5d - 10
Add ten to both sides.
40 + 10 = 5d - 10 + 10
50 = 5d
Then divide 5 by both sides.
50/5 = 5d/5
Answer.
d = 10

~

Next equation.
-2(x - 9) = -24
Distribute the -2.
-2x + 18 = -24
Subtract 18 from both sides.
-2x + 18 - 18 = -24 - 18
-2x = -42
Then divide -2 by both sides.
-2x/-2 = -42/-2
Answer.
x = 21

ok so the y-axis is the one that goes down, so basically you want to draw the line how it is but like a how mirror does it.

Parallel lines never intersect, therefore, do not have a solution.
a. True
b. False

Answers

If the lines are parallel to each other, it won't intersect. It means that we can't get any intersect point by solving equations. There is no coordinate which satisfy both lines.
