Answer:
[tex]\huge\boxed{x=17}[/tex]
Step-by-step explanation:
It's important to note that when two angles create a straight line, they are supplementary.
This means their angle measures add up to 180° since a 180° angle is a straight line.
Since we know the measures of both angles in equation form, we can add them together and have them equal 180 to solve for x.
[tex](5x-18) + (4x+45) = 180[/tex]
Combine like terms:
[tex]9x + 27 = 180[/tex]
Subtract 27 from both sides:
[tex]9x = 153[/tex]
Divide both sides by 9:
[tex]x = 17[/tex]
So x = 17.
Hope this helped!
Answer: x = 17
Step-by-step explanation:
Remember that supplementary angles add up to 180.
We also know that two angles create a straight line.
We have to find x in (5x-18)° and (4x + 45)°.
Now, we know that (5x-18) and (4x + 45) is 180.
Now, let's get started.
5x and 4x is equal to 9x.
Now, we have to combine the like terms.
9x + 27 = 153.
Subtract the number 153 from 180.
You get 17, so it is the answer.
Hope this helps!

Miriam withdraws $13 from her bank account once each day for five days. What integer represents the change in the amount in the account?
(Other: Use a pencil and paper. Find the integer that would represent the change in the amount if Miriam deposits $13 into her bank account once each day for five days. Explain the difference between the integer for the withdrawals and the integer for the deposits.)
Answer: $-65 and $65
Difference=130
Step-by-step explanation:
You just multiply 13 and 5 because it is 13 dollars for 5 days. It’s the same answer for both problems except one is a negative and one is a positive. To find the difference between both integers you add 65 and 65 to get an integer of 130.

Line A and B are parallel lines transverse by line C. What is the measure of angle x?
Answer:
The angle x is equal to 30°.
Step-by-step explanation:
We are given that
Lines A and B are parallel.These lines are transversed by Line C.We can find out what angle is the supplement of 150° by setting up a simple equation.
[tex]\text{150 + x = 180}\\\\\text{x = 30}[/tex]
Then, we can use the Corresponding Angles Postulate. This states that when two parallel lines are cut by a transversal, the angles that are corresponding (not a supplement) are congruent to each other.
Therefore, the angle that is to the top right of x is equal to 150°.
Finally, we need to find x. We can do this by using the same equation above and finding the supplement. We know this is 30°, so x = 30°.

Lindsey’s cookie recipe uses 1 1/2 cups of brown sugar to make 2 dozen cookies. Lexi wants to make only 1 dozen cookies. How much brown sugar should Lexi use?
Answer:
3/4 cups
Step-by-step explanation:
Answer:
1.5 cups
Step-by-step explanation:
144 cookies divided by 24 cookies is 6. This means that we will be making 6 batches of 24 cookies. We will then multiply 1/4 by 6, which means that we will need 1.5 cups of brown sugar for 144 cookies.
What is the y-intercept of the function below?
2x - 3y = 12
Answer:
The slope is −23
Step-by-step explanation:
You can use the intercepts to graph the line. The graph of 2x + 3y = 12 crosses the x-axis at (6, 0), so its x-intercept is 6. The graph of 2x + 3y = 12 crosses the y-axis at (0, 4), so its y-intercept is 4.

both can drive 128 miles in 2 hours
Step-by-step explanation:
Divide the distance by the time to get the unit rate
260/4=65
201/3=67
multiply by 2 to see how far they can go in 2 hours
65x2=130
67xx2=134
both are over 128 so they can travel 128 miles in 2 hours.
2(2x - 8) > 4(3x - 12) Solve the inequality (Just like my previous problem) Make sure to show work!!
Answer:
x < 8
Step-by-step explanation:
This is a special case, so at the end of the equation we'll flip the sign.
Distribute:
2 * 2x = 4x
2 * -8 = -16
4x - 16
4 * 3x = 12x
4 * -12 = -48
12x - 48
4x - 16 > 12x - 48.
Subtract 12 from both sides.
12 - 12 = 0
4x - 12x = -8x
-8x - 16 > -48
The additive inverse of subtraction is addition so do -16 + -48, which equals -64
-8x/-8 = x
-64/-8 = 8
Now this is where we flip our sign so here we go :)
x < 8
There.
Hope this helped and sorry if I'm wrong.

Shya works part-time at a gift-wrapping. the store sells wrapping paper rolls and package of wrapping rolls. there are a total of 125 rolls and package. each roll costs $3.50 and each package costs $2.25. the total of all of the rolls and package is $347.50 . how many rolls of wrapping paper are there? show good work and explanation.
Answer:
y=72
x=53
there are 72 packages
Step-by-step explanation:
3.5x+2.25y=347.5
x+y=125
Thereby y=125-x
so
3.5x+2.25(125-x)=347.5
3.5x-2.25x+281.25=347.5
1.25x=66.25
x=53
53+y=125
y=72
Answer:
60 rolls
Step-by-step explanation:
first thing you want to do is add 3.50 +2.25 = 5.75
Then you divide 347.50 by 5.75
which is 60.34...
if you round that off it will be 60 rolls
