15 is 75 % of 20

20/15 = 100/75

Answer:

75%

Step-by-step explanation:

Well lets set this up.

You want to find what percent of 20 is 15.

So to do that you can make it a fraction.

The numerator is what is being divided and the denominator is what you want it divided by.

So you want 15 divided by 20

So 15 is numerator

20 is denominator.

[tex]\frac{15}{20}[/tex]

A fraction is basically a division problem so now all you need to do is divide 15 by 20.

If you do that you should get a decimal answer of 0.75

To make a decimal a percentage all you have to do is multiply it by 100.

0.75 * 100

[If you do not have a calculator on you an easy way to do this is look at how many zeros 100 has and move the decimal right that many times]

75

Now just add that percent sign and you have 75% as your answer!

Step-by-step explanation:

Answer:

9+x*-7=-19

9-7x=-19

-7x=-19-9

-7x=-28

x=-28/-7

x=4

The number 4 is the required expression.

The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.

Let x be the required number.

And the given expression is the sum of 9 and the product of a number and -7 is -19

That means ,

9 + x × -7 = -19

Using PEMDAS,

9 - 7x = -19

-7x = -19 -9

-7x = -28

x = 4

Therefore, the required number is 4.

Answer:

Step-by-step explanation:

3 more than 1/3 represents 3 + 1/3 Which would equal 3 and 1/3 or 10/3. This is different than 3 since it equals 9/3. They don’t equal each other due to it being 3 added to 1/3

Answer:

4:1

Step-by-step explanation:

Let us assume that the cost of water is free, that is Rs.0.

Let x represent the number of liters of milk, y represent the number of liters of water and z represent the volume of the mixture in liters, hence:

z = x + y            (1)

Milk cost Rs.5 per liter, water cost Rs.0 per liter and the mixture cost Rs.4 per liter. Therefore:

5x + 0(y) = 4z    (2)

Substituting z = x + y in equation 2 gives:

5x + 0(y) = 4(x + y)

5x = 4x + 4y

5x - 4x = 4y

x = 4y

x / y = 4 / 1

x : y = 4 : 1

The proportion in which the milk is to be mixed with water is 4 : 1, that is 4 liters of milk per 1 liter of water

Answer:

LW = 3, KJ = 6, HJ = 5

Step-by-step explanation:

These two triangles are proportionate, as all the angles are the same. Since twp pf the angles from both shapes are equal, the remaining one must also be equal. Since KH = 8 and LG = 4 (both are similar), we can tell that with the similar sides of the small triangle, you multiply by 2 to get the bigger triangle's similar side. If GW = 2.5, HJ = 2.5*2 = 5. LW must be 3 in order to be half of KJ, which is 6.

Answer:

x= 6

Step-by-step explanation:

since the triangle is isosceles we know that opposite sides are equal

[tex]5x+5=35\\\\5x=35-5\\\\5x=30\\\\x=\frac{30}{5}\\\\x=6[/tex]

Answer:

[tex]\boxed {\boxed {\sf x=6}}[/tex]

Step-by-step explanation:

An isosceles triangle has 2 equal base angles and 2 equal legs.

In this triangle, 16 must be the base, because the base angles are adjacent. Therefore, the legs are 35 and 5x+5. They must be equal to each other.

[tex]35=5x+5[/tex]

Solve for the value of x by isolating the variable on one side of the equation.

5 is being added to 5x. The inverse of addition is subtraction. Subtract 5 from both sides of the equation.

[tex]35-5=5x+5-5 \\ 35-5=5x\\30=5x[/tex]

x is being multiplied by 5. The inverse of multiplication is division. Divide both sides by 5.

[tex]\frac{30}{5} =\frac{5x}{5} \\\frac{30}{5}=x\\6=x[/tex]

The value of x is 6.

Answer:

(a-b) = -25

Step-by-step explanation:

(a+b) = -5

a*b=-150

So one of the letters have to be negative as you can only get a negative product from a positive and negative

There is probably a better way to do this, but I just plug in numbers that I think will work

So, (a*b) = -150, (-15*10) = -150

Okay that works so lets try the other one

(-15+10) = -5

This also works, so lets do the third one

(-15-10) = -25

Answer:

Total Area = 26.75

Step-by-step explanation:

Remark

The hardest triangle to see is the top one. So we'll start with it.

It has a vertical leg of 3.5 and a horizontal one of 2 + 2 + 5 = 9

Top Triangle Area

Area = 1/2 base * height

Area = 1/2 * 9 * 3.5

Area = 15.75

Triangle on the lower left

Area = 1/2 * 2 * 2

Area = 2

Square on lower middle

Area = 2*2

Area = 4

Triangle on lower right area

Area = 1/2 * 2 * 5

Area = 5

Total Area

Total Area = 5 + 4 + 2 + 15.75

Total Area = 26.75
