350% of 880 is 60% of what number?
The equation will be 350 % of 880 = 60% of x
We all know that percent is out of 100, so we can express the percentage as a fraction out of 100, and we know "of "means multiply, so our equation becomes
350/100 * 880 = 6/100 * x
then we cross out zeros, so
35/10 * 88 = 6/10x
30800 = 6x
x = 5133.333 is the rounded answer
I hope this helps! :)
The answer is 30800/6
Laura is designing a rectangular porch for her house. On her scale drawing, the vertices of the rectangle are (2, 7), (8, 7), and (2, 9). What are the coordinates of the fourth vertex?

1 point
(7,9)
(8,9)
(7,2)
(2,8)
The fourth vertex will have the same y-coordinate as the third vertex, which is 9. And since the rectangle is a right angle, the fourth vertex will have the same x-coordinate as the second vertex, which is 8.
Therefore, the coordinates of the fourth vertex are (8,9).
So the answer is (8,9).

Which is the graph of the linear equation y = –1/4 x + 3?
*
1 point
Option 1
Option 2
Option 3
Option 4
Option 3 is the graph of the linear equation y = –1/4 x + 3.
The slope of the line is negative, which means the line slopes downwards from left to right. The y-intercept is 3, which means the line intersects the y-axis at the point (0,3).
Option 1 has a positive slope, Option 2 has a different y-intercept, and Option 4 has a slope of 1.

Find three solutions of the equation y = 9x – 4.

a. (–5, –49), (–2, –22), (3, 23)
b.(–5, –49), (2, –22), (3, 23)
c.(–5, –49), (–2, 22), (–3, 23)
d.(5, –49), (–2, 22), (–3, 23)
b. (–5, –49), (2, –22), (3, 23) are three solutions of the equation y = 9x – 4.
To find these solutions, we can choose any value of x and plug it into the equation to find the corresponding value of y.
For example:
- When x = -5, y = 9(-5) - 4 = -49, which gives us the point (-5, -49)
- When x = 2, y = 9(2) - 4 = 14, which gives us the point (2, -22)
- When x = 3, y = 9(3) - 4 = 23, which gives us the point (3, 23)
Each of these ordered pairs is a solution to the equation y = 9x - 4.
