Answer:

4 containers

Step-by-step explanation:

4 containers of juice x 10 people= 40 people to serve

88km

26/13 = x/44

44*26 = 13x

1144 = 13x

x= 88

Answer:

88

Step-by-step explanation:

[tex] \frac{26}{13} = \frac{x}{44} [/tex]

reduce the first ratio

[tex] \frac{2}{1} = \frac{x}{44} [/tex]

cross multiply and divide

[tex]x = 88[/tex]

Answer:

y=x-10

Step-by-step explanation:

slope equal to

[tex]m = \frac{ - 4 - ( - 6)}{6 - 4} = \frac{2}{2} = 1[/tex]

y=mx+c(constant)

-6=1×4+c, then c=-10

Answer:

x = 5

Step-by-step explanation:

Step 1: Distributive property

Using this property means when you have something like the equation on the right side ( 4 ( x + 3 ) ) you multiply both the values in the parentheses by the number outside:

4 ( x + 3 )

( 4 x X ) + ( 4 x 3 )

4x + 12

8x + 2 = 2x + 4x + 12

Step 2: combine like terms

Combining like terms is when you find like terms with the same variables and such and add them together:

8x + 2 = 12 + ( 2x + 4x )

8x + 2 = 12 + 6x

Step 3:Using inverse operations

This means that you need to get a variable one one side and a constant on the other:

8x + 2 ( -2 ) = 12 ( -2 ) + 6x

8x = 10 + 6x

8x ( -6x ) = 10 + 6x ( -6x )

2x = 10

Step 4: solve for the variable

The last thing you need to do is divide both sides by the constant with the variable ( 2x ) to get x by itself:

2x ( /2 ) = 10 ( /2 )

x = 5

Answer:

x=5

Step-by-step explanation:

Step 1:Using the distributive property on the right side of the equation

8x+2=2x+4(x+3)

8x+2=2x+4x+12

Step2:Combining the like terms on the right side if the equation (Since there are no like terms on the left side) :

8x+2=6x+12

Step 3: Using the inverse operations to get the variables on the left side and the constants on the right side of the equation :

8x-6x=12-2

Step4: Using inverse operation to solve for the variable of interest which is 'x':

2x=10 (Dividing both sides by two sides by 2)

x=5

Answer:

Yes. f(x) and g(x) are inverses of one another

Step-by-step explanation:

[tex]f(x) = - \frac{1}{2} x - 2 \\ y = - \frac{1}{2} x - 2 \\ x = - \frac{1}{2} y - 2 \\ x + 2 = - \frac{1}{2} y \\ - 2(x + 2) = - \frac{1}{2} y \times - 2 \\ - 2x - 4 = y \\ {f }^{ - 1} (x) = - 2x - 4[/tex]

In step 1 we just copied the original function.

In step 2 we substituted y for f(x).

in step 3 we switched the variables.

in step 4 we added 2 to both sides.

in step 5 we multiply both sides by -2

In step 6 we solved for y.

In step 7 is just a fancy way of saying the inverse function f(x) = -2x - 4

17x+20

hope it helps

mark me brainliest pls

Answer:

17x+20

Step-by-step explanation:

like terms= 7x and 10x so add= 17x

unlike term 20 it remains as it is.

so 17x+20 further cannot be simplified as both are unlike terms

where is the problem at

Step-by-step explanation:

"keep-change-flip" is a strategy used to dividing fractions.

always change the mix fraction to a improper fraction and you slove.

I'll do the first one and the rest is basically done the same way.

for the last fraction equation I cross multiply the 4 divided into 4 gives you 1 and the 3 divided into 21 gives you 7.

The equation is y = 0.60x. Then the total cost of 9 lbs of bananas will be 5.4 lbs.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

The cost of bananas, y, is directly proportional to x, the pounds of bananas purchased. Then the relationship is given as,

y ∝ x

y = kx

Then the relationship between 'x' and 'y' will be linear.  If 2.5 lbs of bananas cost $1.50. Then we have

1.50 = k (2.5)

k = 0.60  

Then the equation is given as,

y = 0.60 x

Then the total cost of 9 lbs of bananas will be given as,

y = 0.60 (9)

y = 5.4 lbs

The equation is y = 0.60x. Then the total cost of 9 lbs of bananas will be 5.4 lbs.

Step-by-step explanation:

This problem is very simple, all we need to do is take the information we get and put it in equation form.

Jessie made 15 calls, Clay made 3 times as many as her. 15 times 3 is 45. Put in equation format it will look like:

n = (J) * (3)

n is how many calls Clay made, and J is how many calls Jessie made.

Answer:

  (x -1/4)(x -1)(x +1)

Step-by-step explanation:

Pairs of coefficients have the same ratio, so it is likely that you can factor this by grouping pairs of terms.

  x³ -x -1/4x² +1/4 = (x³ -x) -(1/4x² -1/4) . . . . . . note the signs

  = x(x² -1) -1/4(x² -1)

  = (x -1/4)(x² -1)

The difference of squares (x² -1) is a special form that has factors (x -1)(x +1)

Your factoring is ...

  (x -1/4)(x -1)(x +1)

If you want the value of x in (9x+18) = (2x+19)

then

    (9x + 18) = (2x + 19)

9x + 18 - 18 = 2x + 19 - 18

             9x = 2x + 1

      9x - 2x = 2x - 2x + 1

Answer:

A) 2

Step-by-step explanation:

The square root of 4 is 2 because 2 x 2 = 4.

The equation says x = 4, and what your trying to solve is the square root of that, not the root. The root to 4 would be 16 if it was reversed.
