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
Solve for a: a+b=C
Select one:
a. a. a=b+c
b. a=b-c
c. a=c-b
d. b=C-a
Answer:
b.
Step-by-step explanation:
a+b = c
so a is c-b then you have the answer
If a=b+7 and b+7=9, then a=9
Answer:
a = 9
b = 2
Step-by-step explanation:
Given : a = 9
a = b + 7
9 = b + 7
b = 9 - 7 = 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:

Estimate the value of 7 to two decimal places. Draw a number line and locate and label your estimate.
Answer:
Radical 7 is between 2 and 3, so radical 7 is about 2.65.
Step-by-step explanation:
Since 2 squared = 4 is too low and 3 squared = 9 is too high, we know it is somewhere between 2 and 3.
Since 7 is closer to 9 than it is to 4, we also know that the estimate will be closer to 3 than it is to 4.
Since 7 is only 2 units away from 9 and 3 units away from 4, we can estimate that it isn't too much closer to 3 and would be more towards to middle.

The perimeter of the rectangle below is 104 units. Find the length of side QR.
Write your answer without variables.
S
R
2y - 1
QR = 0
Х
P
3y + 3
Answer:
length of side QR = 19 units
Step-by-step explanation:
Perimeter of a rectangle = (2 × length) + (2 × breadth)
length = side PQ = side SR = 3y + 3
breadth = side QR = side SP = 2y - 1
》2×(3y + 3) + 2×(2y - 1) = 104
》(6y + 6) + (4y - 2) = 104
10y + 4 = 104
10y = 104 - 4 = 100
y = 100/10
y = 10
Length of side QR = 2y - 1
= 2(10) - 1
= 20 - 1
= 19 units

reflections. plsss helpp will mark brainliest :) if you don't know don't put anything at all. :)
Point G' has coordinates (-5, 2). If it was reflected across the y-axis, what were the coordinates of its pre-image?
(5, -2)
(2, -5)
(-5, -2)
(5, 2)
Answer:
(5, 2)
Step-by-step explanation:
If we're reflecting across the y-axis, the y value of the point stays the same, because we're going from left to right in this case. The x point, on the other hand, gets inverted (- to + and + to -). -5 becomes 5 and 2 stays the same.

5, 2

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.
