7x+12+63=180
8x+12=180
Subtract 12 from both sides
8x= 168
=c=21

10x-40=50
Add 40 to both sides
10x=90
X=9

4x+72+2x-12=180
6x +60 =180
Subtract 60 from both sides
6x=120
X=20

roll the die twice. what is the probability of rolling a 6 on the 1st roll? an odd number on the 2nd roll?
Crank
The probability of rolling a 6 on the 1st roll is \frac{1}{6}, since there is only 1 out of 6 sides of the dice that has six pips.

The probability of rolling an odd number is \frac{1}{2}, since there are 3 out of 6 sides of the dice that has an odd number of pips. \frac{3}{6} =  \frac{1}{2}

Then the probablity of both events happening one after another is \frac{1}{12}. You have to multiply both probabilities of the events: \frac{1}{6} *  \frac{1}{2} = \frac{1}{12}

Consider the two triangles shown below are the two triangles congruent
mixer [17]

Answer: Yes

Step-by-step explanation: Let's first find the missing angle in the second triangle and to find this angle, remember that the sum of the measures of a triangle is 180 degrees so you should find that our missing angle is 67°.

Now, notice that we have two angles and the included side of one triangle

congruent to two angles and the included side of a second triangle.

Therefore, we can say the triangles are congruent by ASA.

You are looking for a new cell phone plan. The first company, Cellular-Tastic (f), charges a
Step2247 [10]

Answer:

200 minutes

Step-by-step explanation:

Given that:

Cellular - Tastic (f) :

Monthly fee = $35

Per minute fee = $0.11

Dirt cheap call (g) :

Monthly fee = $55

Per minute fee = $0.01

How many minutes would you need to use for the cell phones to cost the same

amount?

Let number of minutes for cost to be equal = x

35 + 0.11x = 55 + 0.01x

Collect like terms

0.11x - 0.01x = 55 - 35

0.1x = 20

x = 20/0.1

x = 200

Hence, for cost to be the Same, 200 minutes must be used
