3x+4=10

3x=6

x=2

Answer:

x=2

Step-by-step explanation:

3x+4=10

3x=6       by subtracting the 4

x=2         by dividing the 3

The cost of a large single chocolate is $0.25.

Given is that April and bill went to the grocery store to buy chocolate bars. April bought 4 small chocolate bars and 6 large chocolate bars and 3 large chocolate bars. April paid $16.50 and bill paid $11.25.

We can write -

4x + 6y = 16.50                               ... Eq{ 1 }

3x = 11.25                                            ... Eq{ 2 }

On solving the equation, we get -

{x} = 11.25/3

{x} = 3.75

Now, we can write -

4x + 6y = 16.50

4 x 3.75 + 6y = 16.50

6y = 16.5 - 15

6y = 1.5

y = 1.5/6

{y} = 0.25

Therefore, the cost of a large single chocolate is $0.25.

Answer:

$79.12

Step-by-step explanation:

Given the following :

Cost per order = $12.80

Number of people = 5

Gratuity left for waitress = 15%

Tax rate = 7.5%

Total bill before tax:

$12.80 * 5 = $64

Bill after tax:

$64 * (1 + 7.5%)

64 - 4.8

= $68.80

Final amount paid:

After tax bill + (after tax bill * Gratuity rate)

$68.80 + (68.80 * 15%)

= $79.12

Answer:

She should make 122 Styrofoam lions and 268 Styrofoam Husky's

The maximum profit, she makes is  $1109

Step-by-step explanation:

The given information are;

The volume required to make each lion = 8 oz

The time it takes to make each lion = 35 minutes

The amount of profit each lion brings = $2.50

The volume required to make each Husky = 12 oz

The time it takes to make each Husky = 20 minutes

The amount of profit each Husky brings = $3

Let the number of lion Styrofoam cups she makes = x

Let the number of Husky Styrofoam cups she makes = y

Therefore, we have;

x × 35 + y × 20 = 9650..........(1)

x × 8 + y × 12  = 3840.............(2)

Dividing equation (2) by 8 and making x the subject, we get;

x × 8/8 + y × 12/8  = 3840/8

x + 4/3·y = 480

x = 480 - 4/3·y

Substituting the value of x in equation (1) gives;

(480 - 4/3·y) × 35 + y × 20 = 9650

16800 - 80/3·y = 9650

y = 268.125

x = 480 - 4/3·y  = 480 - 4/3×268.125 = 122.5

Therefore, she can make 122 Styrofoam lions and 268 Styrofoam Husky's

The maximum profit, she makes is therefore given by the following equation;

The maximum profit = 122 × 2.5 + 268 × 3 = $1109.

Answer:

8 months

Step-by-step explanation:

Given that,

Total budget = 275

Membership fee = 25 per month

Flat discount = 75

We need to find for how many months of gym membership I can afford. The equation will look like :

25x=275-75

Answer:

First son receives $15000

Second son receives $8000

Third son receives $7000.

Step-by-step explanation:

Let first son receive $x and deposit it at 7%

Second son receive $y and deposit in 8%

Third son receive $z and deposit in 6%

Now, let's set up equation using the given information.

The second son share is 1000 more than the third son.

So, we can set up equation as

y= 1000+z

First son share is equal the second son and the third son put together.

So, x=y+z

And we can set up equation for total 30000 as

x+y+z=30000

Plug in y as 1000+z and x as y+z

We get third equation as

y+z+1000+z+z=30000

Plug in again y as 1000+z

It gives,

1000+z+z+1000+z+z=30000

Combine like terms,

2000+4z=30000

Subtract both sides 2000

4z=28000

Divide both sides by 4

z=7000

Now, plug in z as 7000 into y=1000+z to get y =8000

Now, x =y+z plug in the y and z values

x= 8000+7000=15000

Let's check with interest,

15000(7%)+8000(8%)+7000(6%)=2110

1050+640+420= 2110

2110=2110.

Yes! The calculations are correct!

Answer:

The equation gives only the total vertical distance traveled by the firework or maximum height reached by the firework

Step-by-step explanation:

Given;

A function that models the fireworks vertical distance with no respect to time,x, as;

f(x)=-16x^+96x+112

The equation gives only the total vertical distance traveled by the firework, it does not account for the position of the firework at a particular time.

Thus, with the given function we can only estimate the maximum height reached by the firework.

Ed's combined distance for the first three days is 38.58 miles.

Given that, Ed ran 12.56 miles on one day, 12.98 miles the second day, and 13.04 miles on the third day.

Decimals are one of the types of numbers, which has a whole number and the fractional part separated by a decimal point. The dot present between the whole number and fractions part is called the decimal point.

The total distance can be determined as follows:

Total distance = 12.56+12.98+13.04

= 38.58 miles

Hence, Ed's combined distance for the first three days is 38.58 miles.

Answer: t = 22x + 50

Step-by-step explanation:

t = total amount earned

x = hours worked

We know his friend payed $50, so that is our initial value. We don’t need hours for that one.

For his job as trainer, he earns $22 per hour but we don’t know how many hours he earned, so that is x. That is how I got the 22x.
