An explanation for this is that a straight line has a angle degree value of 180. Therefore if you draw the line that creates a 139 degree angle, the rest of the line would have an angle measurement of what is left of the 180 degrees. So to get x you would start with the 180 degree straight line value and subtract the 139 degrees of the line that divides it. so equation is:
180 - 139 = x
And and you get 41 degrees.
(To word this another way the two angles of x and 139 have to add up to the straight line of 180 degrees. Therefore another equation could be:
139 + x = 180
which is basically the same equation but might be easier explanation for some to understand.)


questions 7 and 8 are the same but instead of straight line with 180 degrees, you start with right angle with 90 degrees. Therefore x and the 18 degree angle have to add up to 90 degrees making an equation of:
x + 18 = 90
Or
x = 90 - 18
answer would be
x = 7w

What is the standard form of y= 1/4x +6
viktelen [127]

Answer:

x-4y=-24

Step-by-step explanation:

Standard form is Ax + By = C, so we want x to be on the left side

To accomplish this, subtract 1/4x from both sides.

-\frac{1}{4} x+y=6

Multiply by -4 to get x to be equal to 1.

x -4y=-24

Solve the inequality 171>-6x and graph the solution what does the graph look like
krok68 [10]

To solve the inequality, you need to isolate/get x by itself:

171 > -6x    Divide -6 on both sides [dividing/multiplying a negative number on

-28.5 < x      [dividing/multiplying a negative number in an inequality causes the sign (<, >, ≤, ≥) to flip]

-28.5 < x    [x is a number greater than -28.5]

So your graph should have an open circle at -28.5 (the first small line next to -28), and the arrow pointing to the right since x is greater than -28.5 (increasing)      The 1st option is your answer

[use the o---> and put it at -28.5]

A machine can make 56 parts in 4 hours.It can also make 70 parts in 5 hours. Write an equation that relates the number of parts
ira [324]

Answer:

126 parts in 9 and a half hours

Step-by-step explanation:

56 parts in 4 hours

that means 56 parts in 240 mins

9 hours and 30 minutes in minutes is 570 minutes

56m parts:240 mins

                 540 mins

to get to 540 from 240, you multiply by 2.25.

you can work this out by doing 540 divided by 240

now, multiply 56 by 2.25.

the answer is 126 parts
