Evaluate if m=1 and n=2 what’s 15m/n+1-m^2+n

Answer:

24 minutes

Step-by-step explanation:

This can be explained with the equation y=2x+10 (I chose 2 arbritrary variables, any are acceptable). A week is equivalent to 7 days so x=10. Plug this into the equation and you end up with 24, because 2(7)+10=24

Answer:

m = 4

Step-by-step explanation:

[tex]16(4 - 3m) = 96( \frac{ - m}{2 + 1} )[/tex]

[tex]64 - 48m = 96 \times \frac{ - m}{3} [/tex]

[tex]64 - 48m = - 32m[/tex]

[tex] - 48m + 32m = - 64[/tex]

[tex] - 16m = - 64[/tex]

[tex]m = 4[/tex]

Answer:

Step-by-step explanation:

The balls - multiples of 3 are:

The probability of a multiple of 3 is:

30% probability is in the range 0%-50% so this event is unlikely

Total multiples=3

[tex]\\ \sf\longmapsto P(3)=\dfrac{Multiples\:of\:3}{Total \:balls}[/tex]

[tex]\\ \sf\longmapsto P(3)=\dfrac{3}{10}[/tex]

[tex]\\ \sf\longmapsto P(3)=30\%[/tex]

So it is unlikely to happen.

Answer:  b = -20

Step-by-step explanation:  I have difficulty reading the table of values of (x,y).  I picked just the first (10, -120) to calculate b.

y = -10x + b

-120 = -10(10) + b

b = -20

That should work for all the points:

(20, -220) :  -220 = -10(20)-20 - Yes, etc.

But the values towards the end of the table don't makes sense/don't work.  (0, -2)????

Answer:

4x-8

Step-by-step explanation:

For any number x, "eight fewer than four times a number" can be found using the equation 4x-8.

Answer:

60×8 = 480 + 140 = 620

80×8 = 640

Answer:

a taco is 1.25 and a drink is 0.95

Step-by-step explanation:

tacos = t

drinks = d

5t + 3d = 9.10

3t + d = 4.70

this is a simultaneous equation so times the first one by one and the second by 3 and then take them away from each other and solving to get

t = 1.25 and d=0.95

one drink is $0.95

one taco is $1.25

Hope this helps!!

The basic idea is that multiplying by 10 just moves the decimal point one place to the right.  It makes the number bigger.

Examples:

3.1 x 10 = 31

3.1 x 10 x 10 = 31 x 10 = 310

Each time you multiply by another 10, the decimal point moves one more place.

In your exercise, [tex]10^3[/tex] says you're going to multiply by 10 three times in a row.  So that will move the decimal point 3 places to the right.

So what do you get if you move the decimal in 4.25 three places to the right?

Answer:

-48 is answerrrrrrrrrr

Answer:

-48

Step-by-step explanation:

Hello Again!

The midpoint divides a length into two equal distances.

Equation: 4x+2 = 4x+2

or 2(4x + 2) = 5x + 13

x =

2(4x + 2) = 5x + 13

8x + 4 = 5x + 13

-5x        -5x

3x + 4 = 13

-4          -4

3x = 9

divide 3 on both sides:

x = 3

PQ = 28

4(3)+2 + 4(3)+2

24 + 4

28

Answer:

17

Step-by-step explanation:

a^2 + b^2 = c^2

a^2 = 8^2 = 64

b^2 = 15^2 = 225

64 + 225 = 289

c^2 = 289

c = Square root of 278

c = 17

The image of (-9,-5) after a reflection over the line y = -x is (5, 9) after applying the geometric transformation.

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

It is given that:

The coordinate of the point: (-9, -5)

The reflection line: = y = -x

The transformation rule:

(x, y) → (-y, -x)

The image of (-9,-5) after a reflection over the line y = -x is (5,9).

Thus, the image of (-9,-5) after a reflection over the line y = -x is (5, 9) after applying the geometric transformation.

#SPJ2

Answer:

undefined

Step-by-step explanation:

slope = ((y2-y1)/2) / ((x2 - x1 )/2)

since x1 = x2

so x2 - x1 = 0

then ((y2-y1)/2) / 0 = undefined

Answer: photo MATH

Answer:

p=-7/3=-2.333

Step-by-step explanation:

Step 1: You can rearrange the equation to get a simpler and easier form to understand what to do next. In this case, rearranging it while keeping the same question would end up in -2-(6/7*p)=0

Step 2: Simplify 6/7. That would be in getting zero as your answer, but the equation form would be -2-(6/7*p)=0. Then subtract the fraction from a whole as -2=-2/1=(-2*7)/7 while adding up the two equivalent fractions, (-2 • 7 - (6p))/7=(-6p - 14)/7.

Step 3: Pull out the like factors. So to make it easier, you would have to solve -6p - 14  =   -2 • (3p + 7). This would get you the equation at the end (-2 • (3p + 7))/7=0.

Step 4:  When a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.  Now, to get rid of the denominator, you must multiply both sides of the equation by the denominator.

Here's how:

 -2•(3p+7)

 ————————— • 7 = 0 • 7

     7    

Now, on the left hand side, the  7  cancels out the denominator, while, on the right hand side, zero times anything is still zero.  The equation now takes the shape :

  -2  •  (3p+7)  = 0

Since it's now time to solve each equation individually, it would be -2=0, which we know isn't true and the right answer. That leaves 3p+7=0. So subtract 7 from both sides to get 3p=-7. And with last thing to do, divide both sides by 3 to get your final answer of p = -7/3, your final answer. Hope this helps :)

Answer:

-$79

Step-by-step explanation:

If i read that correctly, Rylee had -$23 in her account.

Then, she was charged $56, meaning we have to subtract $56 from -$23. When we do -23 - 56, we get -79. Meaning, Rylee now has a balance of -$79.

Answer:

Step-by-step explanation:

The original price of Rylee’s groceries was $23.50. This money is leaving her bank account, so represent the amount with a negative sign:

-$23.50.

Rylee got a 20% discount on her purchase. In other words, she got 20% of her money back. The expression that represents the net change in her bank account is

-$23.50 – (-$23.50 × 0.2).

Further simplify the expression by factoring -$23.50 from both terms:

-$23.50 – (-$23.50 × 0.2)

=

-$23.50(1 – 0.2)

=

-$23.50(0.8).

Answer:

Step-by-step explanation:

Answer:

Find the common difference and the next term of the following sequence:

3, 11, 19, 27, 35...

Step 1. To find the common difference, subtract any consecutive pair of terms.

11 - 3 = 8

19 - 11 = 8

27 - 19 = 8

35 - 27 = 8

The difference is always 8, so d = 8.

Step 2. Use the common difference to find the next term.

Since the last term was 35, adding the common difference of 8 will find the next term. The next term is 35 + 8 or 43.
