Answer:

P/2 -w = l

Step-by-step explanation:

P = 2l + 2w

Subtract 2w from each side

P-2w = 2l + 2w-2w

P -2w = 2l

Divide each side by 2

(P-2w)/2 = 2l/2

P/2 -w = l

Answer:

198

Step-by-step explanation:

10% less of 220  

=> 220 - 10% of 220

=> 220 - (10/100 × 220)  

=> 220 - 22

=> 198

A. y ≤ 1

Step-by-step explanation:

according to the graph, the coordinates of maximum value is (-3, 1) and besides the graph towards down, so, the range of the function is y ≤ 1

Answer: bn= 150*3^(n-1)( bn is a quantity of bacteria in generation n)

Step-by-step explanation:

It looks like geometrical sequence, each next generation is three times greater than previous one. So the r of this sequence is 3.

The first generation has 150 representatives, so b1=150

The formula of geometrical sequence is bn=b1*r^(n-1)

(in our case bn is a quantity of bacteria in generation n)

so bn= 150*3^(n-1)( bn is a quantity of bacteria in generation n)

Step-by-step explanation:

In the equation -7 - (-8), there are two 'minus' signs; we can convert two minus signs into a plus sign according to the 'minus minus equals plus' rule, that would make the equation (-7) + 8 for which the answer is +1.

Answer:

1

Step-by-step explanation:

-7-(-8)

therefore;

  -7-(-8)= -7+8

therefore;

   -7+8= 1

Hope you understand.If you have any problem just ask me I will solve it.

Step-by-step explanation:

Using the power law of indices:

When two numbers with the same base multiply,add the exponents that is

[tex] {a}^{2} \times {a}^{3} = {a}^{2 + 3} = {a}^{5} [/tex]

Again,when two numbers with the same base divide, subtract the exponents,that is

[tex] {a}^{2} \div {a}^{4 } = {a}^{2 - 4} = {a}^{ - 2} [/tex]

There are way too many examples that is why I have elaborated the two laws for your perusal.

So for instance:

1.

[tex] {2}^{2} \times {2}^{5} = {2}^{7} [/tex]

Answer:

2² × 2⁵ = 2⁷

            = 128

4⁴ × 4⁶ = 4¹⁰

           = 1048576

6² × 6⁷ = 6⁹

           = 10077696

9⁸ × 9⁸ = 9¹⁷

           = 1.6677182e+16

Do try the rest out yourself!!! You can do it!!!

Hi :)

6 - x > -9

6 - 16 > -9

-10 > -9

What I did was substitued an integer for x that would just break even and then be more than -9.

Answer:

4

Step-by-step explanation:

We can find the slope using the slope formula

m = ( y2-y1)/(x2-x1)

    = ( 3 - -1)/( 7-6)

    = ( 3+1)/( 7-6)

    = 4/1

   =4

Answer:

1/2 of the coconut.

Step-by-step explanation:

1/5 is equal to 2/10, so we can add these two fractions as 3/10 + 2/10, or 5/10.  Simplifying this gets us 1/2, so you and your friend eat, in total, half of the coconut.  

Answer:

√2 and √3

Step-by-step explanation:

Answer:

Step-by-step explanation:

√2 and 5√2 are two irrational numbers

Answer: 1/4n-12=6

1n/4-12=6

n=72

Step-by-step explanation:

Answer:

72

Step-by-step explanation:

let the number be n , then

[tex]\frac{1}{4}[/tex] n - 12 = 6 ( multiply through by 4 to eliminate the fraction )

n - 48 = 24 ( add 48 to both sides )

n = 72

Answer:

Answer:

[tex]3(5n - 2) \times (2n - 5)[/tex]

Step-by-step explanation:

[tex]30 {n}^{2} - 87n + 30[/tex]

[tex]3(10 {n}^{2} - 29n + 10)[/tex]

[tex]3(10 {n}^{2} - 4n - 25n + 10)[/tex]

[tex]3(10 {n}^{2} \times (5n - 2) - 25n + 10)[/tex]

[tex]3(2n \times (5n - 2) - 5(5n - 2))[/tex]

[tex] = 3(5n - 2) \times (2n - 5)[/tex]

Answer:

The slope is 3/5

Step-by-step explanation:

–3x + 5y = 10

Rewrite the equation in slope intercept form  y = mx+b where m is the slope and b is the y intercept

Add 3x to each side

5y = 3x+10

Divide by 5

y = 3/5 x + 10/2

The slope is 3/5
