The measure of a triangle is 180 degrees. In other words the sum of the angles of a triangle is 180 degrees

To solve for x set all of the expressions of angles equal to 180 and isolate x

11x - 3 + 7x + 5 + 13x - 8 = 180

31x + (- 6 + 6) = 180 + 6

31x/31  = 186 / 31

x = 6

To find the measure of each angle plug 6 into the x into each individual expression

Hope this helped!

A jar Contains 18 strawberry- 24cheery- and 19 lime-flavored candy the rest of the candies are chocolate there are 82 candies an
tresset_1 [31]

Answer:

61 + n = 82

Step-by-step explanation:

So the total number of candy is 82. This is the sum of each type of candy, i.e. 18 + 24 + 19 + n. So we have

18 + 24 + 19 + n = 82

61   +    n            = 82

( if we solve the equation we get n = 82 - 61 = 21)

Hope it helps and if it does please mark me brainliest;)

Answer:

They are only equal on day 0, both having 10 population.

Step-by-step explanation:

Given the bacteria on the counter is initially measured at 5 and doubles every 3 days we can generate the following geometric equation:

f(x)=10*2^{\frac{x}{3} }

Given the bacteria on the stove is measured at 10 and doubles every 4 days we can create another equation:

f(x)=10*2^{\frac{x}{4} }

To find how many days it will take for the bacteria population to equal the same lets set both equations equal to eachother:

10*2^{x/3}=10*2^{x/4}

Divide both sides by 10

2^{x/3}=2^{x/4}

Since both exponents have the same base we can set the exponents equal to eachother and solve for x:

\frac{x}{3}=\frac{x}{4}

Multiply both sides by 3 to isolate x on the left side

x=\frac{3x}{4}

Multiply both sides by 4 to remove fraction

4x=3x

Subtract 3x to isolate x on the left side

x=0

Plug x into one of our original equations

f(0)=10*2^{0/3}

Solve

f(0)=10
