there were 8 apples in each bag but after she ate one from each bag, there are only 7 apples in each bag
Step-by-step explanation:
Which expressions are equal to 0 when x = -1? Check all that apply.
4(x + 1)
(4 x + 5)
4(x - 1)
(5 - 4x)
4(x - (-1))
(4 x + 5)
4 (X + (-1))
(4 x + 5)
4 (x + 1)
(5 - 4x)
Answer:
4(x + 1) and 4(x - (-1))
Step-by-step explanation:
4(-1 + 1) = 4(0) = 0
(4 (-1) + 5) = -4 +5 = -1
4(-1 - 1) = 4(-2) = -8
(5 - 4(-1)) = 5 + 4 = 9
4(-1 - (-1)) = 4(0) = 0
4 (-1 + (-1)) = 4(-2) = 8

Write the equation of the line 1x + 3y = 6 in y = mx + b form.
Answer:
y = -1/3x + 2
Step-by-step explanation:
1x + 3y = 6
3y = -x + 6
y = -1/3x + 2
Answer:
[tex]y=-\frac{x}{3}+2[/tex]
Step-by-step explanation:
1x + 3y = 6
We want the y to be isolated, so we subtract x from both sides,
3y = 6 - x
Now we divide everything by 3, to isolate y
[tex]y=-\frac{x}{3}+2[/tex]

A company makes steel rods shaped like cylinders. Each rod has a diameter of 8 centimeters and a height of 20 centimeters. If the company used 28,134.4 cm3 of steel, how many rods did it make?
Answer:
1,172.3 cm³
Step-by-step explanation:
Find the volume of one rod, then divide the total volume of steel used by the volume of one rod. The volume of one rod is
V = (πd²/4)h
d = 4 cm
h = 20 cm
Plugin the numbers and get V in cm³, then divide the given total volume of 28,134.4 cm³ by V. If the result is not an integer, then round down.
Add
20 + 4 = 24
Then
28,134.4 ÷ 24 = 1172.26
Rounded to the nearest 0.1 or the Tenths Place = 1,172.3
Therefore, 1,172.3 rods will be made per hour.

What is the value of x?
3 (-1 - 8x) = -3
Answer:
x = 0
Step-by-step explanation:
3 x -1 = -3 and 3 x -8x = -24x
-3 + 3( the opposite of the -3 given in the parentheses) = 0
-24x = 0
0/-24 (from -24x)= 0
x = 0

3 people can deliver 1000 letters in 30 minutes.
How long would it take 1 person to deliver all 1000 letters?
If there are 5 people delivering would it take more or less time?
How long will take 5 people to deliver 1000 letters?
Answer: It would take 1 hour and 30 minutes for one people do it.
If 5 people do it would take less time. If there are 5 people delivering the letters it would take them 12 minutes ti deliver all 1,000 letters.
Does anyone know how he got from step 1 to step 2??????????
9514 1404 393
Explanation:
Both sides of the equation are squared.
[tex]\dfrac{x-12}{4}=\sqrt{x} \qquad\text{given}\\\\ \left(\dfrac{x-12}{4}\right)^2=x \qquad\text{square both sides}\\\\ \left(\dfrac{x}{4}-3\right)^2=x \qquad\text{divide out the fraction}\\\\ \dfrac{x^2}{4^2}-\dfrac{6}{4}x+9=x \qquad\text{$(a-b)^2=a^2-2ab+b^2$}\\\\\dfrac{x^2}{16}-\dfrac{5x}{2}+9=0 \qquad\text{subtract $x$}[/tex]
I like this better without fractions, so would multiply by 16 at this point (or earlier).
x^2 -40x +144 = 0
(x -36)(x -4) = 0
x = 4 or 36 . . . . . . x = 4 is extraneous
The solution is x = 36.

What is the y=mx+b of the equation 3x−2y=12
Answer:
y=3/2x-6
Step-by-step explanation:
To find the y=mx+b you need to move the y on one side while moving the others on the other side
First, move the 3x to the other side by subtracting by 3x on both sides:
-2y=-3x+12
Divide by -2 on both sides:
y=3/2x-6
Answer:
y=3/2x-6
Step-by-step explanation:
3x-2y=12
isolate the y:
-2y=-3x+12
get rid of the coefficient in front of y by dividing by -2
y=-3/-2x+12/-2
y=3/2x-6
