Answer:

x = 5

Step-by-step explanation:

As it is an isosceles triangle so two sides BA and BC are equal. So,

BA = BC

3x + 3 = 2x + 8

3x - 2x = 8 - 3

x = 5

Therefore AC = 5

Answer:

I think 1

Step-by-step explanation:

Answer:

3/2x + 4

Step-by-step explanation:

3x - 2y = -8

-2y = -8 - 3x

y = 4 + 3/2x

Answer:65 degrees

Step-by-step explanation: a triangle has 180 degrees.

one angle is 45 degrees and the other is 70

if we add them together we get 115

180-115 is 65

m3 is 65 degrees

Answer:

Number of coins that are not nickels = 55 coins

66 = 55 + n

number of nickels in the​ jar = 11

Step-by-step explanation:

Pennies = 17

Dimes = 12

Quarters = 26

Nickels = n

Total coins = 66

How many of the coins are not​ nickels?

= Pennies + Dimes + Quarters

= 17 + 12 + 26

= 55 coins

Number of coins that are not nickels = 55 coins

what equation could you use to find​ n?

Total coins = Pennies + Dimes + Quarters + nickels

66 = 17 + 12 + 26 + n

66 = 55 + n

n = 66 - 55

n = 11

number of nickels in the​ jar = 11

a) ok, heres what u graph, and ur ordered pairs

graph the following points:

(0,0) (1,5) (2,10) (3,15) (4,20) (5,25) (6,30) (7,35), and so on

b) One of the ordered pairs I can use is (1,5). This is beacuse the ordered pair explains that for every video game (x), 5 will be the cost (y).

Answer: The probability a person has both diagnoses = 4.5%

Step-by-step explanation:

Given: Chances of getting influenza = 30% = 0.30

Chances of getting appendicitis  = 15% = 0.15

Since both the events are independent , so the probability a person has both diagnoses will be

P(influenza and appendicitis) =P(influenza) x P(appendicitis)

[tex]=0.30\times0.15\\\\=0.045\\\\=4.5\%[/tex]

Hence, the probability a person has both diagnoses = 4.5%

Answer:

D. 120°

Step-by-step explanation:

Complementary angles have a sum of 180 and since its twice the measure of the smaller one so the smaller one would have to be 60 in order for the bigger one to be 120 because you then add your two angles and it should make 180

Answer:

Step-by-step explanation:

Supplementary angles sum to 90. We are told the larger angle is twice the smaller.

L=2S, S=L/2

S+L=90, using S=L/2 we have

L/2+L=90

(3L)/2=90

3L=180

L=60

Answer:

A

Step-by-step explanation:

The statement which is most accurate based on the data is option(D)A prediction based on the data is reliable, because the means of the samples are close together.​

Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers

From the given data,

Mean of the sample 1 = 15.9

Mean of the sample 2 = 15.7

Mean of the sample 3 = 15.6

All three mean are close together.

Therefore the data is reliable

Hence, the statement which is most accurate based on the data is option(D)A prediction based on the data is reliable, because the means of the samples are close together.​

Answer:

X intercept is -3/7

Answer:

3, -3, -1/2

Step-by-step explanation:

There is no need to distribute, just set each parenthesis to equal to zero.

p(x)= (x-3)(x+3)(2x+1)

         X-3=0                     x+3=0                      2X+1=0

           +3  +3                     -3  -3                           -1  -1

             X=3                        X=-3                          2x=-1

                                                                                x=-1/2

Answer:

It would take alot of time for be to fill everything out so the simple solution is, complementary angles add up to 90 degrees and supplementary add up to 180 degrees. Simply for complementary do 90 - m<1 = m<2, and for supplementary 180 - m<3 = m<4.

Infinite Solutions

Step-by-step explanation:

3(5x - 4) needs to be simplified

So we multiply 5x by 3

So 3 x 5x = 15x

Then we multiply -4 by 3

3 x -4 = - 12

Put those together we get 15x - 12

The same equation as the one on the right side

So since 15x - 12 = 15x - 12, the x variable can be any number
