The angles of an equilateral triangle are congruent. If x represents the measure of one angle of an equilateral triangle, which equation represents the sum of the angle measures of the triangle ?1. x + x= 90%
2.x + x + x = 90%
3.x + x = 180%
4.x + x + x = 180%

Answers

Answer 1
Answer: 4) x + x + x = 180°

An equilateral triangle has three sides of equal length. Its interior angles are also equal. Since interior angles of a triangle should sum up to 180°, then each angle is 60°, making each angle congruent with one another.

So if x is equal to one angle and triangles have three angles then, 

x + x + x = 180°

or 3x = 180°
Answer 2
Answer:

The equation represents the sum of the angle measures of the triangle is

x + x + x = 180%.

Option 4 is the correct answer.

We have,

The sum of the angle measures in any triangle, including an equilateral triangle, is always 180 degrees.

Since an equilateraltriangle has three congruent angles, each angle in the triangle is x degrees.

Therefore,

The equation that represents the sum of the angle measures of the equilateraltriangle is:

x + x + x = 180 degrees

Thus,

The correctequation is x + x + x = 180%.

A baker is calculating the charge for two types of cookies.What formula tells the cost,in dollars,if chocolate chips cookies are $1.00/dozen and lemon frosted are $2.00/dozen? Let c = number of dozens of lemon frosted; T= total charge.

Answers

My answer would be the top left. If you would like me to explain just comment and i will get back to you on that.
T= total charge
C= # dozen chocolate chip
L= # dozen lemon frosted

Total equals (chocolate chip price times the # dozen of chocolate chip) plus (lemon frosted price times # dozen of lemon frosted.)

T= ($1)(# dozens chocolate chip) + ($2)(# dozens lemon frosted)

T= ($1)(C) + ($2)(L)
T= 1C + 2L

The equation is: T= 1C + 2L, answer is top left choice.

Hope this helps! :)

Christopher just found beautiful yarn for 20% off. He can make one scarf from 2/3 of a ball. If Christopher buys 12 balls of yarn, how many scarves can he make?

Answers

Answer: There are 18 scarves which he can make.

Step-by-step explanation:

Since we have given that

Number of balls Christopher bought = 12

From (2)/(3) of a ball, he can make 1 scarf.

So, from 12 balls , number of scarves he can make is given by

\frac{\text{Number of balls }}{\text{Number of balls to make 1 scarf}}\n\n=(12)/((2)/(3))\n\n\n=(12* 3)/(2)\n\n=(36)/(2)\n\n=18

Hence, there are 18 scarves which he can make.
He can make 18 scarves.                     

3/5 =2/3t what is t PLZ HELP

Answers

3/5 = (2/3)t
cross multiply
9/10 = t
2/3t = 3/5

Divide (inverse operation)

2/3t/2/3 = 3/5 divided by 2/3

3/5 * 3/2 = 9/10

t = 9/10

Answer: t = 9/10

Which answer best describes the solution to the equation 3m – 9 = 9 + 3m?

A.
one solution

B.
no solution

C.
an infinite number of solutions

D.
m = 27

Answers

let's check
3m - 9 = 9+3m
collect like terms
3m -3m = 9 + 9
0m = 18
which is not possible, so it will not have any solutions 
3m - 9 = 9 + 3m
-3m             -3m
0m - 9 = 9
       +9  +9
     0m = 18
       0      0
       m = 0
B. no solution
