In this number sequence or pattern we can see that the numbers are being multiplied by themselves. In this example 2 multiplied by itself is 4 and 4 multiplied by itself is 16 and so on. Hope this helps, have a great day!

Answer:

151

Step-by-step explanation:

Answer:

Step-by-step explanation:

(x+7)/2= -8

x + 7 = -16

x= -23

(y + 1)/2 = -9

y + 1 = -18

y = -19

(-23, -19)

Hey there! I'm happy to help!

An exponent of two means you square the number. So, we have -9×-9. Two negatives makes a positive, so our answer is 81.

Have a wonderful day! :D

Answer:

A. it is true for both equations

Step-by-step explanation:

x = 4 and y = 1

sub these values into the equations

4 + 1 = 5

4 - 1 = 3

Answer:

8x-3

Step-by-step explanation:

The total perimeter is the length of all the sides of the triangle added together, in this case that is 11x+1. In order to get the length of the one side by itself subtract the other two side lengths from the perimeter. (11x+1)-(x+5)=10x-4. (10x-4)-(2x-1)=8x-3.

Answer:

b or c

Step-by-step explanation:

2×-1 +1= -1

-1>-3

2×0+1= 1

1>-3

For this reason the equality can be b or c

10x + 6p

Hi there !

4x + 3p + 3p + 6x =

= (4x + 6x) + (3p + 3p)

= x(4 + 6) + p(3 + 3)

= x·10 + p·6

= 10x + 6p

Good luck !

Greetings from Brasil...

Note the graph of the function eˣ (or e⁻ˣ). We conclude that for any value of X, the result will be between 0 and +∞.\

So there is no value for X that the result of m.eˣ (or m.e⁻ˣ) is negative.

So you can answer:

For the equation of the statement of the question, with any value of X, we will always obtain a number greater than zero

(OBS: we'll never get zero. We can get very close, but never zero)

Answer:

x=8

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    -1/2*x+3-(-x+7)=0

simplify 1/2

((0 -  (1/2• x)) +  3) -  (7 - x)  = 0

Adding a whole to a fraction

Rewrite the whole as a fraction using  2  as the denominator :

        3     3 • 2

   3 =  —  =  —————

        1       2  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

-x + 3 • 2     6 - x

——————————  =  —————

    2            2  

(6 - x)    

 ——————— -  (7 - x)  = 0

    2      

ubtracting a whole from a fraction

Rewrite the whole as a fraction using  2  as the denominator :

            7 - x     (7 - x) • 2

   7 - x =  —————  =  ———————————

              1            2    

Adding up the two equivalent fractions

(6-x) - ((7-x) • 2)     x - 8

———————————————————  =  —————

         2                2  

x - 8

 —————  = 0

   2  

When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 x-8

 ——— • 2 = 0 • 2

  2

Now, on the left hand side, the  2  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  x-8  = 0

Solve  :    x-8 = 0

Add  8  to both sides of the equation :

                     x = 8

Hope this helps :)

Answer:

x=8

Step-by-step explanation:

Original equation: -1/2x+3 = -x+7

First, you must isolate the x value to be alone on 1 side. Steps 1 and 2 do this.

1. Subtract 1/2x to both sides.

This results in:

-0.5x + 7 = 3

Because -x - (-1/2x) = -x + 1/2x = -0.5x

2. Subtract 7 from both sides.

This results in:

-0.5x = -4

Because 3 - 7 = 4

Then, you simply get rid of the -0.5 by multiplication. Steps 3 and 4 accomplish this.

3. Multiply the whole equation by -1

-1(-0.5x) = -1(-4) —> 0.5x = 4

We did this to make it easier to see the equation.

4. Divide the whole equation by 2

2(0.5x) = 2(4) —> x = 8

Your answer is x = 8 because 0.5 times 2 is 1 and 2 times 4 is 7, and you can now ignore the 1 because anything times 1 is itself.

So x=8.

Answer:

X = 11

Complementary angles

Step-by-step explanation:

Complementary angles are when two angles add up to 90 degrees.

3x + 10 + 47 = 90

3x + 10 = 43

3x = 33

x = 11

Answer:

3p+4=25

Step-by-step explanation:

3p+4=25

Answer:

Step-by-step explanation:

Isolate the variable

3p + 4 - 4 = 25 - 4

Simplify

3p = 21

Solve for p

3p/3 = 21/3

p=7

Step-by-step explanation:

20x12= 240cm^2 (the size of one brick)

If there are 5000 bricks then you multiply 240cm^2 by 5000

5000x240= 1,200,000cm^2

(it's a huge number so I'm not so sure about this)

Answer:

The answer is 224

Step-by-step explanation:

You would have to multiply 45 by 7 which is 315

Then subtract 315 from 987 which equals 672 then divide 672 and 3 which is 224.

Answer:

20% decrease

Step-by-step explanation:

New value =

465 - Percentage decrease =

465 - (20% × 465) =

465 - 20% × 465 =

(1 - 20%) × 465 =

(100% - 20%) × 465 =

80% × 465 =

80 ÷ 100 × 465 =

80 × 465 ÷ 100 =

37,200 ÷ 100 =
