The answer is 4.5.
The formula for a rectangle is A = lw. Substitute the formula, so it'll be 27 = (2x - 3) * x. Evaluate the formula.
Hope this helps you! And rate me to see if I did it right. Thanks!
Answer:
133 girls
Step-by-step explanation:
Total members = x
Number of boys =
Number of girls =
Number of boys + Number of girls = total members
x = 171
Number of boys = = 2 * 19 = 38
Number of girls = 38 + 95 = 133
Answer:
First you have to find out the number of ounces in a pound. Then, multiply that number by the price per pound
Step-by-step explanation:
Answer:
y = -2x - 3
Step-by-step explanation:
Please look carefully at this graph. There are two red dots on the graph. The x- and y-coordinates of one are (-5,7) and those of the other are (0,-3).
Now as we move to the right, from (-5,7) to (0,-3), x increases by 5 and y decreases by 10 (note that 7-10 is -3). Thus, the slope of this line is
m = rise / run = -10/5, or m = -2.
Then the equation of this line, in point-slope form, is
y-7 = -2(x-[-5])x, or y-7 = -2(x+5). This is in point-slope form.
If you'd like to have it in slope-intercept form, manipulate y-7 = -2(x+5) as follows: (a) add 7 to both sides, obtaining y = -2(x+5) + 7, and (b) perform the indicated multiplication: y = -2x - 10 + 7, or y = -2x - 3.
So 32=(number of boxes) times (number of books per box)
number of books per box=8
number of boxes=n
32=n times 8
so equation is
32=8n
sol divide both sides by 8
32/8=8/8n
4=1n
4=n
4 boxes
