Answer :

1. -3x + 6 = -9

-3x = -9 - 6

-3x = -15

x = -15 / -3

x = 5

2. 5m + 4m = 72

9m = 72

m = 72 / 9

m = 8

3. 6d - 10d = 40

-4d = 40

d = 40 / -4

d = -10

4. 2(x + 4) = 30

2x + 8 = 30

2x = 30 - 8

2x = 22

x = 22 / 2

x = 11

5. 78 = -2(m + 3) + m

78 = -2m - 6 + m

78 = -m - 6

78 + 6 = -m

84 = -m

m = -84

What is the total number of possible outcomes rolled when rolling six dice?

marta [7]

The dice has 6 sides so out of 100% it would be 100/6=16.6666 so each side had a 16.6666% chance

5mn^4 • 5m^2 n^3 Does that even makes sense

xeze [42]

Answer:

25m^3n^7

Step-by-step explanation:

Let's write out the equation

5mn^4 • 5m^2n^3

When we multiply exponents with similar bases, you add them together.

For example 2^2 • 2^2= 2^4

Numbers with no exponent are to the power of one

For example: 2= 2^1

Now that we know this, let's combine like terms

5 • 5=25

m^1•m^2=m^3

n^4•n^3=n^7

Answer: 25m^3n^7

the length of the longer leg of a right triangle is 3 ft more than three times the length of the shorter leg. the length of the

Ulleksa [173]

with the pythagorean theorem

$\begin{gathered} (4+3x)^2=x^2+(3+3x)^2 \\ 16+24x+9x^2=x^2+9+18x+9x^2 \\ 16+24x+9x^2=10x^2+18x+9 \\ 16+24x+9x^2-9=10x^2+18x+9-9 \\ 9x^2+24x+7=10x^2+18x \\ 9x^2+24x+7-18x=10x^2+18x-18x \\ 9x^2+6x+7=10x^2 \\ 9x^2+6x+7-10x^2=10x^2-10x^2 \\ -x^2+6x+7=0 \end{gathered}$

using the formula of the quadratic equation

$\begin{gathered} x_{1,\: 2}=\frac{-b\pm\sqrt{b^2-4ac}}{2a} \\ x1=\frac{-6+\sqrt{6^2-4\left(-1\right)\cdot\:7}}{2\left(-1\right)}=-1 \\ x2=\frac{-6-\sqrt{6^2-4\left(-1\right)\cdot\:7}}{2\left(-1\right)}=7 \end{gathered}$

the length cannot be negative, therefore x=7

length of the shorter leg is: 7ft

length of the longer leg is: 3+3(7)= 24ft

length of the hypotenuse is: 4+3(7)= 25ft
