Amanda and her group of friends spent a total of $35.50 on 7 hot dogs and 6 cheese burgers. Greg and his group of friends spent $30.50 at the same snack bar on 5 hot dogs
and 6 cheese burgers.
For your answer WRITE THE EQUATIONS and state how much hot dogs cost and cheese burgers cost.

Answer:

Step-by-step explanation:

The first cat eats 1/15 of a bag per minute.

The second cat eats 1/10 of a bag per minute.

Together, they eat 1/15 + 1/10 = 1/6 of a bag in one minute.

Hence both can eat [tex]\frac{2x+3y}{30}[/tex]

when we form equations  out of given statements and then solve them to obtain answer are said word problems.

Given cat x can eat treat = 15 mints

cat x in 1 mint= x/15

given cat y can eat treat = 10 mints

cat y in 1 mint= y/10

hence both cats if eat together =[tex]\frac{x}{15} +\frac{y}{10}[/tex]

=[tex]\frac{2x+3y}{30}[/tex]

hence both can eat [tex]\frac{2x+3y}{30}[/tex].

Answer:

b. 82m³

Step-by-step explanation:

[tex]V = \frac{1}{3}(\frac{1}{2} bh_1)h_2\\b = 8.2m\\h_1 = 4m\\h_2 = 15m\\\\V = \frac{1}{3}(\frac{1}{2}(8.2)(4))(15)\\V = 82m^{3}\\[/tex]

Answer:

B, 82 meters cubed

Step-by-step explanation:

The formula for volume of a triangular pyramid is 1/3Ah, where A = the area of the triangular base, and h = the height of the pyramid.

The area of the base here is 1/2 base x height, so:

1/2 x 8.2 x 4 = 1/2 (32.8) = 16.4 meters squared.

Plug this into the formula for the volume of the pyramid:

1/3 x 16.4 meters squares x 15 meters = 82 meters cubed

Answer: Y = 6

Step-by-step explanation: The equation is this because when you put this equation on a graph, it makes a horizontal line passing through (3,6). When an equation is like Y = 6 it will make a horizontal line on that coordinate of Y, but if it is X = 6 it will make a vertical line on the coordinate of X.

Answer:

The value of y is 110 degrees

Step-by-step explanation:

-we know that the Angle sum property of a quadrilateral is 360 degrees.

- so we can find the 4th angle

- and find y through the linear pair method.

The fourth angle=70 degrees

And y=180-70=110(Linear pair)

Answer:

x² + 9x + 14 can be factored as (x+2)(x+7)

Step-by-step explanation:

The general form is ax² + bx + c. If a=1, then you can start looking for two numbers that multiplied give c and added give b.

14 = 2*7

and

9 = 2+7

hence the easy factorization

(x+2)(x+7)

Keep in mind that it only works if a=1.

Answer:

( + 2 ) (x+7 )

Step-by-step explanation:

Use the sum-product pattern   2 + 9 + 1 4 2 + 7 + 2 + 1 4 2

Common factor from the two pairs   2 + 7 + 2 + 1 4 ( + 7 ) + 2 ( + 7 ) 3

Rewrite in factored form   ( + 7 ) + 2 ( + 7 ) ( + 2 ) ( + 7 )

Answer:

( 32/y ) - 6

Step-by-step explanation:

okay so quotient means the result obtained by dividing one quantity by another and the problem that follows that is 32 and a number, y

this is meaning that 32 and y and going to be dividing (32/y)

less than means subtraction and the number that's surrounding that is 6.

this means that 6 is going to be subtracted from (32/y)

Given:

The figure of a right angle triangle.

To find:

The value of y.

Solution:

If a right angle triangle,

[tex]\cos \theta=\dfrac{Adjacent}{Hypotenuse}[/tex]

In the given right triangle,

[tex]\cos (30^\circ)=\dfrac{4\sqrt{3}}{y}[/tex]

[tex]\dfrac{\sqrt{3}}{2}=\dfrac{4\sqrt{3}}{y}[/tex]

[tex]\sqrt{3}\times y=2\times 4\sqrt{3}[/tex]

[tex]\sqrt{3}\times y=8\sqrt{3}[/tex]

Isolate the y variable.

[tex]y=\dfrac{8\sqrt{3}}{\sqrt{3}}[/tex]

[tex]y=8[/tex]

Therefore, the value of y is 8.

Answer:

ML = 6

Step-by-step explanation:

Since HIJ is a scale drawing of KML, this means the IJ and ML are corresponding sides. The corresponding sides have proportional lengths, so from HJ ≅ LK you can learn that the scale factor is 20 / 5 = 4. likewise you can confirm this with HI ≅ MK is 36 / 9 = 4.

So ML is found by dividing JI by 4 = 24/4 = 6.

Answer:

Step-by-step explanation:

3.4+2(9.7-4.8x)=61.2

2(9.7-4.8x)=61.2-3.4

2(9.7-4.8x)=57.8

9.7-4.8x=57.8/2

9.7-4.8x=28.9

4.8x=9.7-28.9

4.8x=-19.2

x=-19.2/4.8

x=-4

Answer:

Step-by-step explanation:

B. Distribute 2 to 9.7 and −4.8x.

C. Combine 3.4 and 19.4.

E. Subtract 22.8 from both sides.

F. Divide both sides by −9.6.

Answer:

x = 7.5

Step-by-step explanation:

This can be solved via cross multiplying.

6x = 5 × 9 | Multiply the denominators by the respective nominators.

6x = 45 | Multiply 5 × 9

x = 7.5 | Divide 45 ÷ 6 (Division Property of Equality)

Answer:

x=7.5

Step-by-step explanation:

for this you would cross-multiply to get x

6x=9(5)

6x=45

x=7.5
