Answer:

28

Step-by-step explanation:

Given formula:

4s

It is given that the variable, s, is equal to 7. Therefore, plug in 7 for s in the expression:

4s

4(7)

Next, multiply straight across:

4 * 7 = 28

28 is your answer.

Answer:

n = 3

Step-by-step explanation:

to find the value of n

we need to transpose

7n + 12 = 3n+ 8n

7n + 12 = 11n

12 = 11n -7n

12 = 4n

n = 12/4

n = 3

if ur trying to find the value of n then n=3

Step-by-step explanation:

The equation in the question is false.

[tex]x - 2 = 3(x - 4)[/tex]

[tex]x - 2 = 3x - 12[/tex]

[tex]3x - x = 12 - 2[/tex]

[tex]2x = 10[/tex]

[tex]x = 10 \div 2[/tex]

[tex]x = 5[/tex]

Answer:

y=16

Step-by-step explanation:

Multiply all terms by the same value to eliminate fraction denominators

Cancel multiplied terms that are in the denominator

Re-order terms so that constants are on the left

Divide both sides of the equation by the same term

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

Answer:

y is 16

Step-by-step explanation:

[tex]4 = \frac{64}{y} [/tex]

but 64 is 4³:

[tex]4 = \frac{ {4}^{3} }{y} [/tex]

make y the subject:

[tex]y = \frac{ {4}^{3} }{4} [/tex]

from law of indices:

[tex]y = 4 {}^{(3 - 1)} \\ y = {4}^{2} \\ y = 16[/tex]

(B) 0

We have

[tex]p^2 = 2q^2 \implies \dfrac{p^2}{q^2} = \left(\dfrac pq\right)^2 = 2[/tex]

but 2 is not a square number.

Answer:

1. (1, 2)

(1 - 4) Explanation:

If we're asked to move to the right, make the x-coordinate a positive number.

If we're asked to move to the left, make the x-coordinate a negative number.

If we're asked to move upwards, make the y-coordinate a positive number.

If we're asked to move downwards, make the y-coordinate a negative number.

Answer: Fourth Choice. 66

Concept:

Here, we need to understand the idea of evaluation.  

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Solve:

Given information

n = 3

Given expression

6 (n² + 2)

Substitute values into the expression

=6 (3² + 2)

Simplify exponents

=6 (9 + 2)

Simplify values in the parentheses

=6 (11)

Simplify by multiplication

Answer:

25.6 feet

Brainliest, please!

Step-by-step explanation:

10/16 = 16/x

5/8 = 16/x

5 = 128/x

x = 128/5

x = 25.6

The floor of the new tent is 24 feet wide.

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b.

Given that,

Side of old tent = 10 feet,

And width of floor = 15 feet.

Let width of new tent is x feet.

To find the width of a tent whose side is 16 feet,

Use ratio and proportion property,

10/15 = 16/x

x = (16 × 15)/10

x = 240/10

x = 24 feet

The width of the floor of the new tent is 24 feet.
