I am having a party. I purchase:
x pizzas, y 12-packs of soda, and zcupcakes for a party. If each pizza costs $7.50, each 12-pack of soda costs $3.25, and each cupcake cost $0.75, write an equation for the total cost, t,in terms of x, y and z.

Answer:

7.64 miles/week

Step-by-step explanation:

recall the following conversions

1 mile = 5280 feet  or  1 foot = 1 /5280 miles

also

1 week = 7 days = 7 x 24 hours = 7 x 24 x 60 = 10080 min

We are given 4 feet /min. We can apply the above conversions to this to get:

4 feet/min

= 4 feet/min x (1/5280) miles/foot

= (4/5280) miles / min

= (4/5280) miles/min x 10080 min/week

= (4/5280)(10080) miles/week

= 7.636363 miles/week

= 7.64 miles/week   (nearest hundredth)

Answer:

Step-by-step explanation:

Let the width of the margins as x.

So, we subtract 'x' width on each side of the paper.

So, length = 26-x-x= 26-2 x

Width = 27-x-x=27-2 x

Now, it is given printed area is 360

We can set up equation using length x width = Area

(26-2 x)(27-2 x) = 360

Multiply the left side using FOIL method,

702 -52  x-54 x+4 x^2 =360

Combine like terms

702-106x+4x^2=360

Subtract both sides 360

4x^2-106x+342 =0

Let's divide both sides by 2 to simplify

2x^2 -53x+171=0

Let's use quadratic formula to solve.

There are two possible values for x.

Approximately x= 22.46 , x=3.76

Therefore, by Basic Proportionality theorem:

\therefore \frac{x}{x+7} = \frac{x-3}{x+1} \\\\

Answer:

See below

Step-by-step explanation:

The LHS and RHS are exactly the same, so the equality is true.

The associate property of addition says that

[tex]\boxed{a+(b+c)=(a+b)+c}[/tex]

In order to make the addition of fractions, the denominators should be same. So we can write three fractions as one.

[tex]\dfrac{1}{2} +\dfrac{2}{3}+\dfrac{3}{4}[/tex]

Hope this helps plz mark brainliest :D

Answer:

5  7/24≈5.292

Step-by-step explanation:

Subtract

8  1/6 -2 and 7 over 82=127 over 2

Convert mixed number to improper fraction

8 1/6= 8x6/6+ 1/6=16+7/8=23/8

Convert mixed number to improper fraction

2 7/8= 2x8/8+7/8=16+7/8=23/8

Find common denominator

49/6-69/24=196-69/24=127/24

24 is the least common multiple of denominators 6 and 8. Use it to convert to equivalent fractions with this common denominator.

Subtract

196/24- 69/24= 196-69/24=127/24

Simplify

127/24= 5 7/24

Answer:

0.7

Step-by-step explanation:

zero and seven TENths. the place value of the 7 is tenths so on the bottom of the fraction will be 10. i'm bad at explaining so sorry.

the decimal equivalent of 7 / 10 is 0.7.

To find the decimal equivalent of 7 / 10, we divide the numerator ( 7) by the denominator ( 10).

When we perform the division, 7 ÷ 10, we get 0.7.

Therefore, the decimal equivalent of 7 / 10 is 0.7.

In decimal form, the number 0.7 represents 7 tenths or 7 parts out of 10. It indicates that the numerator ( 7) is 7 / 10th of the denominator ( 10). This decimal representation makes it easier to compare the fraction with other decimal numbers and perform arithmetic operations using decimals.

I'm not quite sure these are right. You might wanna check with a classmate or something first.

Step-by-step explanation:

(6x + 10) + (x + 17) + (4x - 34) = 180

11x - 7 = 180

11x = 173

x = 15.73 (answer had repeating decimal so i rounded up in the hundredths place)

(6x + 10)

6 (15.73) + 10

94.38 + 10

Given:

A pilot can travel 450 miles with the wind in the same amount of time as 360 miles against the wind.

Pilot's speed in still air is 315 miles per hour.

To find:

The speed of the wind.

Solution:

Let the speed of wind be x miles per hour.

Speed with wind = 315+x miles per hour

Speed against wind = 315-x miles per hour

We know that,

[tex]Time=\dfrac{Distance}{Speed}[/tex]

According to the question,

[tex]\dfrac{450}{315+x}=\dfrac{360}{315-x}[/tex]

Divide both sides by 90.

[tex]\dfrac{5}{315+x}=\dfrac{4}{315-x}[/tex]

By cross multiplication, we get

[tex]5(315-x)=4(315+x)[/tex]

[tex]5(315)-5x=4(315)+4x[/tex]

[tex]5(315)-4(315)=4x+5x[/tex]

[tex](5-4)315=9x[/tex]

Divide both sides by 9.

[tex]\dfrac{(1)315}{9}=x[/tex]

[tex]35=x[/tex]

Therefore, the speed of wind is 35 miles per hour.
