Explain the steps you could use to solve 3y + 6 = 30 to find y
Answer:
3y+6-6=30-6 (subtract 6 from both sides)
3y=24 (simplfy by subtracting those numbers)
3y/3 = 24/3 (divide both sides of the equation)
y=8 (simplfy by divding with those numbers)
Step-by-step explanation:
Hope this helps :)
Answer:
3y+6-6=30-6

Al and Tom are painting a shed. Working alone, Al can paint the shed in 2 hrs. Together they can paint the shed in 1.5 hours. How long would it take Tom to paint the shed on his own?
Answer:
6 hours.
Step-by-step explanation:
The formula sort of has to be invented.
Al
rate = 1 shed / 2 hours
Tom
rate = 1 shed / x hours.
Together.
rate = 1 shed / 1.5 hours.
Equation
1 shed / 2 hours + 1 shed / x hours = 1 shed / 1.5 hours.
1/2 + 1/x = 1/1.5 Put the fractions over a common denominator.
(x + 2) / 2x = 1 / 1.5 Cross Multiply
1.5(x + 2) = 2x Remove the Brackets.
1.5x + 3 = 2x Subtract 1.5x from both sides
3 = 2x - 1.5x
3 = 0.5x Multiply both sides by 2
6 = x
It would take Al 6 hours to do the shed on his own.

Volume
= 1/3 * π* r² * h
= 1/3 * 3.14 * 5² * 5
= 1/3 * 3.14 * 25 * 5
= 130.83 units ³
Hope it will help :)❤
Answer:
V = 130.83
Step-by-step explanation:
The equation for the volume of a cone is:
[tex]V =\frac{ \pi r^2h}{3}[/tex]
we can see that r = 5, and h = 5
we will use 3.14 for the value of pi
so, we just fill in the equation with the values we know and solve :)
[tex]V=\frac{\pi r^2h}{3} \\V=\frac{(3.14) (5)^2(5)}{3}\\V=\frac{(3.14) (25)(5)}{3} \\V=\frac{392.5}{3} \\V= 130.8333 (approx.)[/tex]
the question wants the nearest hundred, so the final answer is
V = 130.83
can somebody please help
Answer:
Every equation has a solution.

A sports store has 468 golf balls. They will be put into boxes that hold 18 balls each. What is the minimum number of boxes needed for all of the golf balls?
The minimum number of boxes needed for all of the golf balls is 26.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of golf balls = 468
Number of golf balls in one box = 18
The number of boxes.
= 468 ÷ 18
= 468/18
= 26
Thus,
The number of boxes needed is 26.

3(2x+d)+c(x+5)=10x+17 find c and d
Answer:
c = 4, d = - 1
Step-by-step explanation:
Expand and simplify left side, then compare coefficients of like terms on the right side, that is
3(2x + d) + c(x + 5) ← distribute parenthesis
6x + 3d + cx + 5c
= x(6 + c) + 3d + 5c
Compare terms with those on the right side
coefficients of x- terms
6 + c = 10 ( subtract 6 from both sides )
c = 4
--------------
constant terms
3d + 5c = 17, that is
3d + 5(4) = 17
3d + 20 = 17 ( subtract 20 from both sides )
3d = - 3 ( divide both sides by 3 )
d = - 1
The value of c and d if 3(2x+d)+c(x+5)=10x+17 is 4 and -1 respectively
Given the equation:
3(2x+d)+c(x+5)=10x+17
Expand the bracket
6x + 3d + cx + 5c = 10x + 17
Collect the like terms
6x+cx + 3d + 5c = 10x + 17
x(6+c) + 3d + 5c = 10x + 17
Compare the coefficients of x on both sides
x(6+c) = 10x
6+c = 10
c = 10 - 6
c = 4
Similarly:
3d + 5c = 17
3d + 5(4) = 17
3d + 20 = 17
3d = 17 - 20
3d = -3
d =-3/3
d = -1
Hence the value of c and d if 3(2x+d)+c(x+5)=10x+17 is 4 and -1 respectively

PLEASE HELP ILL GIVE BRAINLIEST! PLEASE PUT X AND Y PLOT POINTS! x-3y=3 2x+9y=11
Answer:
( x, y ) = ( 4, 1/3)
Step-by-step explanation:
x - 3y = 3
2x +9y = 11
1. substitute the value of x
x= 3 + 3y
2x + 9y = 11
2. solve equation
2 (3 + 3y) +9y = 11
3. substitute the value of y
y = 1/3
4. solve equation
x = 3 + 3 x 1/3
x = 4
5. check solution
(x, y) = ( 4, 1/3 )
check x ----> 4 - 3 x 1/3 = 3
check y ------> 2 x 4 + 9 x 1/3 = 11
for x----> 3=3
for y----> 11=11

Step-by-step explanation:
9) In parallelogram, adjacent angles are supplementary
14x - 4 + 86 = 180
14x = 180 - 86 + 4
14x = 98
x = 98/14
x = 7
10) In parallelogram, opposite angles are congruent.
6x + 4 = 64
6x = 64 - 4
6x = 60
x = 60/6
x = 10
11) In parallelogram, opposite sides are congruent.
3x + 4 = 2x + 10
3x -2x + 4 = 10
x + 4 = 10
x = 10-4
x = 6
