Simplest way to do this:
number of books= 120
percentage represented by 120= 100%
increase current percent by 55%= 155%
: . 55% increase = original number of books * (155%)
= 120 * (155/100)
= 186
Answer:
Alright solve for x by multiplying both sides of the equation then isolating the variable
x = - 10 Hope this helps :)
Step-by-step explanation:
Answer:
A point on either side of the line
Step-by-step explanation:
To determine which side to shade, you look at a point on each side of the line. One will make the inequality true and one will not. Shade on the side that will make the inequality true
Answer:First inequality: y >

Second inequality: y < 3 + x
Explanation:The inequality in slope-intercept form has the following general formula:
y < mx + c or y > mx + c (according to the given sign)
where m is the slope and c is the y-intercept
This means that to get any inequality in slope-intercept form, we will have to isolate the y on one side of the inequality.
First given inequality:4x - 5y < 1
4x - 5y + 5y < 1 + 5y
1 + 5y > 4x
1 + 5y - 1 > 4x - 1
5y > 4x - 1
y >

comparing this to the general form, we would find that:
slope (m) = 4/5
y-intercept (c) = 1/5
Second given inequality:y - x < 3
y - x + x < 3 + x
y < 3 + x
comparing this to the general form, we would find that:
slope (m) = 1
y-intercept (c) = 3

410 - x/7 +70 = 120
410+70-120=x/7
360=x/7
X =2520
