Answer:

7000

Step-by-step explanation:

Here we will show you and explain using simple algebra how to calculate "what" in this sentence: "700 is 10 times as much as what?"

When using algebra to solve a word problem, read the word problem thoroughly to make sure you understand exactly what it is asking.

To clarify, "700 is 10 times as much as what?" is the same as "700 is 10 times as much as x", "What is x?" or "10 times a number will have a product of 700 - what is that number?"

Based on that information, we created the following equation to solve "700 is 10 times as much as what?":

10 • x = 700

To solve for x, we divide both sides by 10 to get x by itself. Here is the math to illustrate:

10 • x = 700

10x = 700

10x/10 = 700/10

x = 70

Thus, the answer to "700 is 10 times as much as what?" is 70.

In other words, 700 is 10 times as much as 70 because 10 times 70 equals 700. Note that the answer is rounded if necessary.

The multiplication 700 and with the number 10 gives the result 7000.

In multiplication, the numbers being combined are called factors, and the result is called the product.

When you multiply 700 by 10, you are essentially adding 700 to itself 10 times.

Mathematically, it can be represented as:

700 * 10 = 700 + 700 + 700 + 700 + 700 + 700 + 700 + 700 + 700 + 700

             = 7,000

So, 700 times 10 equals 7,000.

Answer:

The number is 4.

The step describe to solve the problem is: add five and then multiply by

Step-by-step explanation:

Let the number be x.

As per the given condition as:

The difference of twice a number and five is three.

"Twice a number" means

"difference of twice a number and five" means

therefore, the translation of the given word problem to an equation is:

Now, solve the equation :

Addition Property of equality states that you add the same number to both sides of an equation.

Add 5 to both sides of an equation we get;

2x-5+5=3+5

Simplify:

2x = 8

Multiplication property of equality states that you multiply the same number to both sides of an equation.

Multiply by  both sides we get;

Simplify:

x = 4

The steps which describe to solve the problem is: add five and then multiply by

Therefore, the number x = 4

Step-by-step explanation:

Answer:

m = 66 & e = 956

Step-by-step explanation:

Create your equations:

$4m + $6e = $6000

m + 890 = e

Substitute/solve for morning tickets:

$4m + $6e = $6000     <--    m + 890 = e

$4m + $6(m + 890) = $6000

$4m + $6m + $5340 = $6000

$10m = $6000 - $5340

m = $660/$10

m = 66 morning tickets

Solve for Regular tickets:

m + 890 = e   <---  m = 66

66 + 890 = 956

e = 956 regular tickets

Double check work:

$4m + $6e = $6000

$4(66) + $6(956) = $6000

Answer:

12

Step-by-step explanation:

When looking at triangles it's always important to remember what the ratios are to parts of triangles. In the case of this triangle let's give the value 24 the variable of E. In every scenario in which Y is positioned above 24 or E, the answer is always E/2=y, or 24/2=y ---> 12.

y / 24 = 12 / 12 + 18

y / 24 = 12 / 30

y / 24 = 2 × 6 / 5 × 6

y / 24 = 2 / 5

y = 24 × 2 / 5

y = 48 / 5

y = 96 / 10

y = 9.6

The sugar needed by Lila to make 1 / 4 of a recipe is 1 / 6 of the total sugar needed to complete her recipe.

A fraction is a percentage of a whole. This entire sentence could be referring to a single location or a collection of locations. The English word "fraction" originates from the Latin word "fraction," which means "to break." As the first society to comprehend fractions, the Egyptians used fractions to solve a number of mathematical problems, including the distribution of food and resources and the absence of a metal currency.

Given:

The sugar quantity in the original recipe = 2 / 3

If Lila is making 1 / 4 of a recipe, so she needs 1/ 4 of the total sugar in the recipe,

The sugar needed by Lila =  1 / 4 of 2 / 3

The sugar needed by Lila = 1 / 4 × 2 / 3,

The sugar needed by Lila = 1 / 6 of the total sugar needed in the recipe.

Therefore, the sugar needed by Lila to make 1 / 4 of a recipe is 1 / 6 of the total sugar needed in the recipe.

Answer:

x = 9/2, y = -5/2

Step-by-step explanation:

5x + y = 20

10x - 2y = 50

There's multiple ways to do this, but I will solve using substitution.

Isolate variable y on the first equation.

5x + y = 20

y = 20 - 5x

Substitute the value of y for 20 - 5x in the second equation.

10x - 2(20 - 5x) = 50

Use distributive property:

10x - 40 + 10x = 50

Combine like terms:

20x - 40 = 50

20x = 90

x = 90/20

x = 9/2

Substitute x for 9/2 and solve for y:

y = 20 - 5(9/2)

y = 20 - 45/2

y = 40/2 - 45/2

y = -5/2

Answer:

x =9/2, y = -5/2

Step-by-step explanation:

5(9/2) + -(5/2)= 20

45/2 + -5/2 = 20

40/2 = 20

10(9/2) - 2(-5/2) = 50

90/2 + 10/2 = 50

45 + 5 = 50
