<span>Simplifying 5(2x + -3) = 15
Reorder terms: 5(-3 + 2x) = 15 (-3 * 5 + 2x * 5) = 15 (-15 + 10x) = 15
Solving -15 + 10x = 15 Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '15' to each side of the equation. -15 + 15 + 10x = 15 + 15
Combine like terms: -15 + 15 = 0 0 + 10x = 15 + 15 10x = 15 + 15 Combine like terms: 15 + 15 = 30 10x = 30
 Divide each side by '10'. x = 3
Simplifying x = 3</span>

5(2x-3)=15 

2x-3=15/5  \text{ Divide both sides by 5} 

2x-3=3 

2x=3+3&#10;  \text{Add 3 to both sides} 

2x=6 

x=6/2  \text{Divide both sides by 2} 

x=3

Triangle L M Q is cut by perpendicular bisector L N. Angle N L Q is 32 degrees and angle L M N is 58 degrees.
Serga [27]

Answer:

Yes

Step-by-step explanation:

ΔMNL ≅ ΔQNL  by ASA or AAS

by ASA

Proof:

∠ LNM = ∠LNQ    =90

LN = LN   {Common}

∠MLN = ∠QLN     {LN bisects ∠ L}

By AAS

∠Q + ∠QLN + ∠LNQ = 180  {Angle sum property of triangle}

∠Q + 32 + 90 = 180

∠Q  + 122 = 180

∠Q = 180 -122 =

∠Q = 58

∠Q = ∠M

∠MNL =∠QNL = 90

LN = LN {common side}

Write an equation for this graph please help me I'm begging u
bekas [8.4K]
First, solve for the slope. This can be found by looking at the y and x intercepts. At x = 0, y = 1.5. At x = 2, y = 0.

Slope is defined as Δy/Δx, or the change in y over the change in x. This means that in order to calculate the slope, you must find the difference between the values of y and divide it by the difference in the values of x for the two points to determine the slope between them.

(0 - 1.5)/(2-0) = (-1.5)/2 = -0.75 or -3/4

Now that you have the slope, we can write the equation in slope intercept form, y = mx + b, where m is the slope we calculated and b is the y intercept, 1.5.

y = (-3/4)x + 1.5

A miniature golf course recently provided its customers with 8 golf balls, 2 of which were yellow. What is the experimental prob
bonufazy [111]

Answer:

<h2>There is a 25% chances of receiving a yellow golf ball next time.</h2>

Step-by-step explanation:

Givens

  • There are 8 golf balls in total.
  • There are 2 yellow golf balls out of 8.

The experimental probability refers to the ratio between the number of times an even happens and the total number of cases. So,

P=\frac{2}{8}=0.25

Therefore, there is a 25% chances of receiving a yellow golf ball next time.
