box a contains 225 ends. Box B contains 320 rulers. Some pens were moved from box to box B and some rulers were moved from box be to box a. In the end and 3/10 of the items in box a and 3/5 of the items in box B were pens. How many rulers were moved from box be to box a?
Answer: 238 rulers
Step-by-step explanation:
Box A=225 pens and box B= 320 rulers
Things in box A=x and things in box B=y (because box A items are over 10 and items in box B are over 5)
Box A = 3/10 are pens (all items in this box are called x)
x + x + x = 3x
y +y+y+y+y+y+y = 7x (rulers moved from box B)
Box B = 3/5 pens
x + x + x = 3y (pens)
x + x = 2y (rulers)
System of equations:
3x + 3y = 225 and 7x + 2y = 320 (simplify the first equation, divide by 3 and multiply by -2 to cancel 2y)
(3x+3y=225)/3 = x+y=75
-2(x+y=75)= -2x-2y= -150
Add both equations
(-2x-2y= -150) + (7x+2y=320) =
5x = 170
X = 34
7*34=238

Please help, Will give brainliest to first answer if correct. Please write formula as well.
Answer:
1). 6x +7 = 4x +19
6x – 4x = 19 – 7
2x = 12
x= 12/2
x= 6
2). 3x + 3 = 7x – 5
7x – 3x = 3 +5
4x = 8
x= 8/4
x = 2
3). 39 – 2v = 3v + 4
3v +2v = 39 – 4
5v = 35
v = 35/ 5
v = 7
4). 4n + 6 = 18 – 2n
4n +2n = 18 – 6
6n = 12
n = 12/ 6
n = 2

When performing a transformation on a set of data, how do you determine if the transformation is successful? (2 points)
If r-squared for the transformation is greater than r-squared for the original regression, the transformation is successful.
If r-squared for the transformation is less than r-squared for the original regression, the transformation is successful.
If r for the transformation is less than r for the original regression, the transformation is successful.
If r for the transformation is greater than r for the original regression, the transformation is successful.
If the intercept for the transformation is greater than the intercept for the original regression, the transformation was successful.
Answer:
If r-squared for the transformation is greater than r-squared for the original regression, the transformation is successful.

Answer:
a = 9
b = 2
Step-by-step explanation:
Given : a = 9
a = b + 7
9 = b + 7
b = 9 - 7 = 2
Write 2/4/9 as an improper fraction.

A line goes through the points (7, 3) and (11, 5). What is the equation of the line? Answer quick pls.
Step-by-step explanation:
slope = ( y2-y1) / (x2-x1)
= (5-3) / (11-7)
= 1/2
y= mx+ b
m = slope
5 = 11/2 + b
5 - 5.5 = b
b = -0.5
the equation y = 1/2(x) - 0.5
The equation of line is x-2y =1
How do you find equation of a line?To find an equation of a line given the slope and a point.Identify the slope.Identify the point.Substitute the values into the point-slope form, y − y 1 = m ( x − x 1 ) . y − y 1 = m ( x − x 1 ) .Write the equation in slope-intercept form.Slope-intercept form: The equation of line with slope m and making an intercept c on the y-axis, is y = mx + c.
Given coordinates are:
(7, 3) and (11, 5)
now, equation of line
(y- y1)= (y2-y1)/(x2-x1) *(x-x1)
y-3 =(5-3)/(11-7) *(x-7)
y-3= 2/4 * (x-7)
y-3= 1/2(x-7)
2y-6= x-7
x-2y =1
Hence, the equation of line is x-2y =1.
