the equation is:

6x - 3 = 7

Not sure if that's what you are asking?

If you solve for x that is:

x = 5/3

Angela and you are painting a room. Angela has 2 1/2 gallons of blue paint and Ryou has half as much white paint. It will take 2

GREYUIT [131]

Conversion from gallons to quarts

1 gallon = 4 quarts

Now,

Angela has $2 \frac{1}{2}$ gallons = $2\frac{1}{2} *4$ = 10 quarts of blue paint

Ryou has 1/2 of what Angela has = 1/2*10 = 5 quarts of white paint.

Each wall requires $2 \frac{3}{4}$ of paint.
After coloring;
Blue colored walls = (10)/( $2 \frac{3}{4}$ ) = 3 walls with 7/11 quarts of paint remaining.
White colored walls = (5)/( $2 \frac{3}{4}$ ) = 1 wall with 9/11 quarts of paint remaining

Graph the system of equations on your graph paper to answer the question. {y=−3x+9y=−x−5 What is the solution for the system of

marysya [2.9K]

y=−3x+9 slope of this equation is -3 and y-intercept is 9

Plot the y -intercept first which is 9 and mark the points using the slope which is -3. Join the points. So blue line in the graph is y = -3x+9

y=−x−5 slope of this equation is -1 and y intercept is -5

Plot the y -intercept first which is -5 and mark the points using the slope which is -1 . Join the points. So pink line in the graph is y = -x-5

The intersection point of these two lines gives you the solution.

The coordinates of point of intersection (7,-12)
