If 3 is added to three quarters of a certain number ,the result is 30 .find the original number.
Answer:
X=36
Step-by-step explanation:
Let x be the unknown number
Three quarters of a number =3x/4
Three was added =3x/4 +3
Final
3x/4 + 3= 30
Multiply through with 4
3x+ 12=120
3x=120-12
3x=108
X=108/3
X=36

ABC shipping charges $7 plus $1 a pound to ship an overnight package. XYZ shipping charges $10 plus $0.75 a pound to ship an overnight package. For what weight is the charge the same for the two companies?
x = lbs
y = total cost
ABC shipping: $7 + $1x = y
XYZ shipping: $10 + $0.75x = y
We set each equation equal to the other.
$7 + $1x = $10 + $0.75x. Subtract $7 from both sides and subtract $0.75x from both sides
$0.25x = $3. Divide each side by $0.25.
x = 12 lbs
When a package is 12lbs the cost is the same.

Answer:
p [tex]\leq \\[/tex] 8
Step-by-step explanation:
Answer:
p[tex]\leq[/tex]8
Step-by-step explanation:
Step 1- Add 7 to both sides of the inequality.
New inequality:
[tex]\frac{p}{8}[/tex] [tex]\leq[/tex]1
Step 2- Now multiply by 8 on both sides of the inequality to get your answer.
Answer:
p[tex]\leq[/tex]8
10 pts The equation y=mx + b goes through the points (6,-2) and (-6, -8). What is the value of m? (-6,-8) What is the value of b?
Answer: m=1/2; b=-5
Step-by-step explanation:
We can use the given points to find slope, then use the y=mx+b equation to find the y-intercept. The formula for slope is [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].
[tex]m=\frac{-8-(-2)}{-6-6}=\frac{-6}{-12} =\frac{1}{2}[/tex]
Now that we know m=1/2, we can use that in y=mx+b to find the y-intercept. We can use any given point to plug into x and y.
y=1/2x+b [plug in x and y]
-2=1/2(6)+b [multiply]
-2=3+b [subtract both sides by 3]
b=-5
Now, we know that b=-5.

Can an equation with the variable inside grouping symbols be written as a two step equation
Answer:
yes
Step-by-step explanation:
In general, a linear equation with a variable anywhere can be written as a 2-step equation. (It may take several steps to get there.)
Example 1:
2(3x +3) = 18 . . . original equation with variable in parentheses
6x +6 = 18 . . . . . 2-step equivalent
Example 2:
4(x -9) +6 = 3(2x +17) . . . original equation
4x -36 +6 = 6x +51
-30 = 2x +51 . . . . . . 2-step equivalent
Answer:
Yes

a water tank is draining at a constant rate if after five minutes the tank is drained by 4.5 gallons what is the rate in gallons per minute at the tank is draining
Answer:
The rate is 0.9 gallon per minute
Step-by-step explanation:
Here, we have 4.5 gallons drained in 5 minutes but we are interested in calculating the rate per minute
Let the amount drained per minute be x
4.5 gallons = 5 minutes
x gallon = 1 minute
Let’s cross multiply;
x * 5 = 4.5 * 1
5x = 4.5
x = 4.5/5
x = 0.9 gallons
