Please help me with this! Two children had 110 marbles between them. After one child had lost half her marbles and the other lost 20 they had an equal number. How many marbles did each child start with and how many did they finish with?

Answers

An equation is a mathematical statement that is made up of twoexpressions connected by an equalsign

x + y = 110

y - (1/2)x = 20

The number of marblesonechildren had is 50.

The number of marblesotherchildren had is 60.

What is an equation?

An equation is a mathematical statement that is made up of twoexpressions connected by an equalsign.

Example:

2x + 4y = 6 is an equation.

2x + 4 is an equation.

We have,

Totalnumber of marbles = 110

Number of children = 2

Number of marblesonechildren has initially = x

Number of marblesotherchildren has initially = y

Now,

x + y = 110 _____(1)

After one child had losthalf her marbles and the otherlost 20 they had an equalnumber.

This means,

x - (1/2)x = y - 20

(1/2)x = y - 20

y - (1/2)x = 20 _____(2)

From (1) and (2) we get,

x = 110 - y _____(3)

Putting (3) in (2)

y - (1/2)x = 20

y - (1/2)(110 - y) = 20

y - 55 + (1/2)y = 20

(3/2)y = 20 + 55

(3/2)y = 75

y = (75 x 2) / 3

y = 25 x 2

y = 50

Now,

Putting y = 50 in (3) we get,

x = 110 - y

x = 110 - 50

x = 60

Thus,

The number of marblesonechildren had is 50.

The number of marblesotherchildren had is 60.

Well both children has 110 marbles between them, and one child lost half and the other lost 20 so then it said they had an equal number so the other girl must had 20 so that makes 40 and 110-40= 80 so 80 is like the marbles that are left

F = 9 5 C + 32 is the formula used to convert degrees Celsius to degrees Fahrenheit. Convert 35°C to degrees Fahrenheit.

Answers

The 35°C in degrees Fahrenheit is F = 95 degrees Fahrenheit after using the formula.

What is unit conversion?

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

It is given that:

F = 9/5 C + 32 is the formula used to convert degrees Celsius to degrees Fahrenheit.

The formula is:

F = 9/5 C + 32

PLug C = 35 degrees C in the formula:

F = (9/5)35 + 32

F = 9x7 + 32

F = 63 + 32

F = 95 degrees Fahrenheit.

Thus, the 35°C in degrees Fahrenheit is F = 95 degrees Fahrenheit after using the formula.

Why do whole numbers with an exponent get bigger while fractions with an exponent get smaller.

Answers

Raising a whole number to a power means:

   Take (a number of things) a number of times, and then possibly
   take that big number of things a number of times again.

Raising a fraction to an exponent means:

   Take a piece of (a piece of one thing), and then possibly
      take just a piece of that smaller piece.

A white-tailed deer can sprint at speeds up to 30miles per hour . American bison can run at speeds up to 3,520feet per minute. Which animal is faster and by how many per hour ? There are 5,280feet in one mile

Answers

Answer:

The Bison is faster by 10 mph.

In 1 minute, the bison runs 3, 520 feet.

In 60 minutes, the bison would run 3520*60 feet = 211, 200 feet per hour.

These are equivalent to 40 miles per hour since 1 mile is equivalent to 5, 280 feet. Hope this helps! ^-^
