Answer:
x=3 sorry if I am wrong.
Step-by-step explanation:
(5x-2)=(3x+4)
-3 -3
2x-2=4
+2 +2
2x=6/2
x=3
Answer:
x = 8 2/3
Step-by-step explanation:
2(3x + 6) = (64-3) + 3
6x + 12 = 61 + 3
6x + 12 = 64
6× = 52
x = 8 2/3
Let x represent Holly's score on 7th math quiz.
We have been given that the mean of Holly's first six math quiz scores was 75%. This means that the average on 1st 6 math quizzes is 75.
To find the total scores on 1st 6 math quizzes, we will multiply 75 by 6 that is .
We will use average formula to find test scores on 7th math quiz.
Let us solve for x.
Therefore, Molly's score on the 7th math quiz was 89.
as you already know, to get the inverse of any expression we start off by doing a quick switcheroo on the variables and then solving for "y", let's do so.
<u>Answer:</u>
<u />
y=77+x
<u>Step-by-step explanation:</u>
The <em>Triangle Angle Sum Theorem</em> states that the sum of all of the angles in any triangle equals 180 degrees.
In the given triangle, two of the angles are already known. The third angle is 180 - y degrees, as all lines measure 180 degrees.
Therefore, the below equation can be put together.
77+x+180-y=180
77+x-y=0
x-y=-77
-y=-77-x
y=77+x
So, y in terms of x is ... y=77+x.
