Answer:

3  2 /7

Step-by-step explanation:

Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.

Answer:

5d

Step-by-step explanation:

Every member pays 5 dollars. So the number will multiply by 5 everytime a member pays.

Answer:

B) 1  7/8

Step-by-step explanation:

1. first, if you have 16/8 then it would be 2, but since it is 15/8 you need to minus 15 and 8

2. 15-8=7, now you only have 7

3. last, since you only have 7 then it is 1 whole and 7 8ths

4. 1  7/8 is your answer.

Explanation:

The geometric mean of two positive numbers a and b is √ab. The ratio a:√ab is equal to the ratio √ab:b.

b

Given:

The expression are

(i) [tex]5x-3[/tex]

(ii) [tex]11-2y^2[/tex]

(iii) [tex]2x-1[/tex]

To find:

The terms which are not constants and their numerical coefficients.

Solution:

Constants: The terms which are free from variables.

Numerical coefficient: Number multiplied with a variable.

(i) [tex]5x-3[/tex]

Constant = -3

Term which is not constant = 5x

Numerical coefficient = 5

(ii) [tex]11-2y^2[/tex]

Constant = 11

Term which is not constant = [tex]-2y^2[/tex]

Numerical coefficient = -2

(iii) [tex]2x-1[/tex]

Constant = -1

Term which is not constant = 2x

Numerical coefficient = 2

Therefore, the terms which are not constants are  [tex]5x,-2y^2,2x[/tex]  respectively and their numerical coefficients are 5, -2, 2 respectively.

Answer:

Step-by-step explanation:

There are multiple solutions.

If each section has n seats, the floor has 22,180-85n seats.

22,180/85 ≅ 260.9, so each section has at most 260 seats.

If each section has 260 seats, the floor has 22,180-85×260 = 80.

Point Form:

(1,3) (5,-9)

Equation Form:

x=1 y=3

x=5 y=-9

solve for the first variable in one of the equations, then substitute the result into the other equation.

Answer:

3. All you did was switch the numbers, so it will still equal the same :)

4. 8a and the other 8a cancel each other out, so since 8 has no variables, it ends up by itself.

Answer:

30$ for 15 cans of coffee.

Step-by-step explanation:

$12 for 6 cans of coffee

12 divided by 6 = 2

$2 per can of coffee

15 cans of coffee times $2 = 30$

Answer:

C. 14

Step-by-step explanation:

The whole side is 28 (AB), so AD must be half of AB. 28/2=14

Answer:

A couple could be 2, 1, or even a decimal 1.3 as an example.

Step-by-step explanation:

Divide both sides by 7:

7n/7 < 21/7

n < 3

Any value of n less than 3 will make the inequality true, so just pick three values (numbers) for n that are less than 3, such as n = 2.

The expression can be expressed as radicals in terms of [tex]\mathbf{\sqrt[3]{17^4} }[/tex]

A radical expression is an expression that can be written in square root form. It is an opposite form of an exponent and its power determines the root in which it is been evaluated.

Here, we are given:

[tex]\mathbf{\implies 17^{^\dfrac{4}{3}}}[/tex]

The denominator in the power will be the root of the expression given, since it is 3 it will be the cube root raised to the power of 4.

[tex]\mathbf{\implies \sqrt[3]{17^4} }[/tex]

Step-by-step explanation:

Remember PEMDAS:

P: we have no parenthesis, so skip this step.

E: no exponents either.

MD (multiplication and division): we have 3x5. when we calculate this, it is equal to 15. Therefore our equation is now simplified to 18-15-2.

AS (addition and subtraction): Subtract in order of first to last. The answer is 1.
