Answer:

Step-by-step explanation:

sum of ∠QPR and ∠RPS is 180 as ∠QPS is a straight line

6x + 11 + 7x + 143 = 180   {add like terms}

13x + 154 =180

13x = 180 - 154

13x = 26

x = 26/13

x = 2

∠RPS = 6x + 11 = 6*2 +11 = 12 + 11 = 23°

I need help with Multiplication Properties of Exponents desperately!! I've tried to solve both problems repeatedly and I cannot
Yuliya22 [10]

Answer:

1) x= -36.

2) x = 0.

Step-by-step explanation:

1) Taking the 3rd power to both sides and using the following exponent law:

\left(a^b\right)^c = a^{bc}

we get:

\left(\left(m^{x}\right)^{\frac{1}{3}}\right)^3 = \left(m^{-12}\right)^3 \\ m^x = m^{-36}

So this tells us that x = -36.

2) We can distribute the power inside every term. So the left side becomes:

\left(3x^3y^x\right)^3 = 3^3\left(x^3)^3y^{3x} = 27x^9y^{3x}

Now, the trick here is to remember that y^0 = 1, so replacing 1 with y^0, which then gives us:

27x^9y^{3x} = 27x^9y^{0}, telling us that 3x = 0 and thus, x = 0.

Use elimination to solve this system of equations. X-4y=-11 and 5x-7y=-10
timurjin [86]
X-4y=-11<=> -5x + 20y = 55
                     <span> 5x - 7y    = -10</span>
                =>0*x + 13*y = 45 => y =45/13 => x = 4*(45/13) -11 = 180/13 -11 =>
x = 37/13;

What is the value of x in the equation 1/2x-3/4=3/8-5/8x?
kipiarov [429]

Answer:

x = 1

Step-by-step explanation:

1/2x - 3/4 = 3/8 - 5/8x

The LCD is 8. Lets change every fraction to a denominator of 8.

4/8x - 6/8 = 3/8 - 5/8x

Now multiply both sides by 8.

4x - 6 = 3 - 5x

Add 5x to both sides. Add 6 to both sides.

9x = 9

Divide both sides by 9.

x = 1
