Step-by-step explanation:

[tex] \frac{5}{8} \times \frac{3}{2} \div \frac{15}{16} \\ \frac{15}{16} \times \frac{16}{15} \\ = 1[/tex]

Answer:

1

Step-by-step explanation:

5/8 x 1 1/2 / 15/16 = 1                        (5/8 / 15/16 = 2/3,   2/3 x 1 1/2 =1 )

Answer:

1994

Step-by-step explanation:

x+(x+1)+(x+2)=75

3x=72

x=24

2018-24=1994

Por lo tanto, el hermano menor tiene 24 años y nació en 1996

Usando un sistema de ecuaciones, se encuentra que el menor nacio en 1994.

Suma de 75, o sea:

[tex]x + x + 1 + x + 2 = 75[/tex]

[tex]3x + 3 = 75[/tex]

[tex]3x = 72[/tex]

[tex]x = \frac{72}{3}[/tex]

[tex]x = 24[/tex]

O sea, el menor tiene 24 años en 2018.

2018 - 24 = 1994, o que implica que el menor nascio en 1994.

Answer:

0.

Step-by-step explanation:

Add 14 on both sides:

-11v+0=v

So we have:

-11v=v

And there is only one number in the universe that can satisfy that and that is 0.

V = 0

-11v = v

0 = v + 11v

0 = 12v

0 = v

v = 0

Answer:

These are both 20 so that means that this is proportional, yes.

Step-by-step explanation:

Hi.

To figure this out we can do something called cross multiplying to find a cross product. If we do this and our two answers are equal then it is indeed a proportion.

Here is how we do this.

[tex]\frac{4}{2}[/tex]    [tex]\frac{10}{5}[/tex]

So basically what we are doing is multiplying across in a diagonal direction.

Diagonal meaning like a slash / .

So in this case we would multiply the 4 and the 5 , since they're diagonal from each other.

Do the same for the 2 and the 10.

So we have to multiply :

4 x 5

2 x 10

=

20

These are both 20 so that means that this is proportional, yes.

Hope this helps.

Yes the ratios 4/2 and 10/5 form a proportion.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

Number of water bottles Hudson buys :

[tex] =\tt 24 \times 2[/tex]

[tex] = \tt48[/tex]

Thus, Hudson buys 48 water bottles.

Cost price of 48 water bottles = 18.50

Cost price of 1 water bottle :

[tex] =\tt \frac{18.50}{48} [/tex]

[tex]\color{plum} =\tt \$0.38[/tex]

Thus, cost price of one water bottle = $0.38

Selling price of one water bottle = $1.25

Selling price of 48 water bottles :

[tex] = \tt48 \times 1.25[/tex]

[tex]\color{plum}=\tt \$60[/tex]

Thus, selling price of 24 water bottles = $60

Which means :

▪︎Cost price = $18.50

▪︎Selling price = $60

Profit = Selling price - Cost price :

Profit Hudson made :

[tex] =\tt 60 - 18.50[/tex]

[tex]\color{plum} = \tt\$41.5[/tex]

Thus, profit Hudson made = $41.5

We know that :

[tex]\color{hotpink}\tt \: Profit \: Percentage =\color{plum} \frac{profit \times 100}{cost \: price} [/tex]

Percentage of profit Hudson made :

[tex] =\tt\frac{41.5 \times 100}{18.50 \times 100} [/tex]

[tex] =\tt \frac{4150}{1850} [/tex]

[tex]\color{plum} =\tt 2.24\%[/tex]

Thus, percentage of profit Hudson earned = 2.24%

● Profit Hudson made = $41.5

● Percentage of profit Hudson made = 2.24%

Step-by-step explanation:

Hello there!, since there is no prior information concerning the activities performed by Susan, I will explain what a number line is and try as much as possible to answer your question from the definition.

A number line is a line on which integers are usually drawn as points separated by a uniform distance. This way, the number line makes addition and subtraction easier, which is very useful when you want to teach someone these operations.

Now, let assume Susan starts from 0 on the number line, to get to the fourth point, Susan needs to move 4 blocks, where each block contains 10 units.

Now, let's assume that Susan is at the third block and the fourth unit, it will take Susan an additional 6 units to get to the fourth point.

NOTE: The solution to this question was provided based on assumption since no much information was given in the question.

The question is incomplete, here is the complete question

Michael split 3/4

pounds of candy among 8 people.

What is the unit rate in pounds per person?

Write your answer in simplest form

SOLUTION:

Micheal splits 3/4 candy among 8 people

Therefore the unit rate per pounds per person can be calculated as follows

= 3/4 ÷ 8

= 3/4 × 1/8

= 3/24

= 1/8

Hence the unit per pound per person is 1/8

Answer: Justin should have multiplied 3.8 and 7.9 first.

Step-by-step explanation:

Given the equation

12.5 + 3.8x

where, x = 7.9, the first thing that Justin's should have done was to multiply 3.8 and 7.9 first. This will be:

= 12.5 + 3.8x.

= 12.5 + 3.8(7.9)

= 12.5 + 30.02

= 42.52

Answer:

3 mph

Step-by-step explanation:

UPSTREAM:

distance = 36 miles ;

Speed = 15-c mph ;

TIME, t = distance / speed = 36/(15-c)

Downstream :

distance = 36 miles ;

speed = 15+c mph ;

time, t = 36/(15+c)

upstream time + downstream time = 5 hrs

36/(15-c) + 36/(15+c) = 5

36(15+c) + 36(15-c) = 5(15-c)(15+c)

1080 = 5(225 - c²)

1080 / 5 = 225 - c²

216 = 225 - c^2

216 - 225 = c²

-9 = c²

c = 3
