Answer:

<h3>X=16</h3>

Step-by-step explanation:

9x + 1 + 5x + 12 + 10x - 37 = 360

24x  - 24 = 360

Add 24 to both sides

24x/24=384/24

answer = 16

hope it helps!!

The container that holds the water for the football team is 2/9 full. After pouring in 12 gallons of water, it is 2/3 full. How
Luden [163]

Answer:

27 gallons

Step-by-step explanation:

Our equation is: \frac{2x}{9} +12 = \frac{2x}{3}

What do we need to find: x

We need to first find x, so lets find x first.

12 =  \frac{2x}{3}  -  \frac{2x}{9}

=> 12 = \frac{6x}{9} - \frac{2x}{9}

=> 12 = \frac{4x}{9}

=> x = 27

Lets go back to our equation.

\frac{2(27)}{9} +12 = \frac{2(27)}{3}

We are going to simplify this before solving this. We are going to get:\frac{54}{9} +12 = \frac{54}{3}

=> 18 = 18

Therefore, we found x and we checked that our x value is correct. Now, we need to find how many gallons can the container can hold.

\frac{3x}{3} = a                                                           [a = gallons can the container hold]

=> x = a

Basically that means the container can hold 27 gallons of water.

Please give me brainliest if this is helpful ;D

A coordinate grid with 2 lines. The first line is labeled y equals negative StartFraction 7 over 4 EndFraction x plus StartFract
KengaRu [80]

Answer:

1) (2.2, -1.4)

2) (1.33, 1)

Step-by-step explanation:

Question 1)

Two lines, with their corresponding equations are given and we have to find the solution to the system of equations.

The given lines are:

Equation of Line 1:

y=\frac{-7}{4}x+\frac{5}{2}

This line passes through the points: (0, 2.5) , (2.2, -1.4)

Equation of Line 2:

y=\frac{3}{4}x-3

This line passes through the points (0, -3) , (2.2, -1.4)

By looking at the graph/given data we have to find the solution of these linear equations.

Remember that the solution of linear equations is an ordered pair, through which both the lines pass i.e. the point at which both the given lines intersect is the solution of the linear equations.

From the given data we can see that both the lines pass through one common point, (2.2, -1.4). Since, both lines pass through this point, this means this is the point of intersection of the lines and hence there solution.

So, the answer to this questions is (2.2, -1.4)

Question 2)

The given equations are:

y = 1.5x - 1                                        Equation 1

y = 1                                                  Equation 2

We can solve these equations by method of substitution.

Substituting the value of y from Equation 2, in Equation 1, we get:

1 = 1.5x - 1

1 + 1 = 1.5x

2 = 1.5x

x = 2/1.5

x = 1.33

y = 1

Thus, the solution of the given linear equations is (1.33, 1)

How much 3 1/4+9 3/8
antoniya [11.8K]

Answer:12 5/8

Step-by-step explanation:

Add the whole numbers together. 3 + 9 = 12

Multiply 1/4 so that it will have the same dnominator as 3/8. 2(1/4)= 2/8

Add the fractions together. 2/8 + 3/8 = 5/8.

Add the whole number and fraction to get a mixed number. 12 + 5/8 = 12 5/8

Through (4,-4) ; perpendicular to 6y=x-12
BARSIC [14]

y = mx + b

m = slope and b = y-intercept


We can arrange 6y = x - 12 in the form of y = mx + b

                  6y = x - 12

                    y = 1/6(x) - 2

Slope of y = 1/6(x) - 2 is 1/6. Taking the negative reciprocal of the slope we get the slope for the perpendicular line.

Negative reciprocal of 1/6 is -6.

The equation for the perpendicular line is

                  y = -6x + b

To find b we can plug in the x and y values of (4,-4) into it since it passes through those coordinates

                -4 = -6(4) + b

                 b = -4 + 6(4)

                 b = -4 + 24

                 b = 20

So the equation for the perpendicular line is y = -6x + 20
