Answer: x + 2x + x-40 = 180

First angle= 55º

Second angle= 110º

Third angle= 15º

Step-by-step explanation: The sum of the angles of a triangle is 180º

Take the values given and use x as the unknown first angle. then create terms for the other two angles based on that:

The second angle of a triangle is double the first angle becomes 2x

The third angle is 40 less than the first angle becomes x-40

x + 2x + x-40 = 180 Solve by adding like terms . x + 2x + x = 4x

4x -40 = 180 Add 40 to both sides to "cancel" the -40 on the left

4x + 40 -40 = 180 + 40 becomes

4x = 220 Divide both sides by 4 to "cancel" the 4 on the left side

4x/4 = 220/4

x = 55 This is the first angle. Substitute 55 for the "x" in the original terms

2(55) = 110 The second angle

(55) -40 = 15 the third angle

How do you find the greatest common denominator, when comparing two numbers? Explain your thought process, in the example I prov

maksim [4K]

Answer:

20 is the greatest common denominator. You can find this by listing the factors of each number. The highest number that can fit into both individual numbers is the common denominator. Since 40 is just 20 doubled, and 20 is just 20 once, it fits into both numbers and is also the highest number that can fit.

Shay mal e 8 2/3 cups of snacks mix she puts all the snack mix into plastic bags she puts 1/3 cup of the snack mix in each bag h

AnnyKZ [126]

Answer:

She needs 26 plastic bags.

Step-by-step explanation:

Given:

Amount of cups of snacks mix = 8 2/3

Rewriting 8 2/3 we get,

Amount of snacks mix = $\frac{26}{3}$

Number of Cups in each bag = $\frac{1}{3}$

She puts all the snacks mix in plastic bags

We need to find the number of plastic bags required to put all the snacks mix

Let number of plastic bag be x.

hence we can say that Number of Cups in each bag multiplied by number of plastic bag is equal to Amount of snacks mix.

$\frac{1}{3}x=\frac{26}{3}\\\\x= \frac{26\times3}{3\times1} =26$

Hence total number of plastic bags she needs is 26.

A taxi cab driver charges a $2.00 initial fee and $1.75 for each mile.

umka21 [38]

1. She can travel 18 miles. Subtract 35 - 2 (initial fee) to have 33. divide 33 by 1.75 to get 18.85. To check how much her total would be, use inverse operations. 18.85 * 1.75 = 32.9875. 32.9875 + 2 = 34.9875. It is barely under $35 but still in her budget.

2. 20m * $1.75 = $35. $70 - $35 = $35. Yes, she can cover the fare. Samantha has more than needed. She can afford the taxi fare and still have money left for future use.

The length of the base of a triangle is twice its height. If the area of the triangle is 64 square kilometers, find the height.

frez [133]

Area of a triangle = base x height / 2
64 = base x height / 2
(multiply 2 on both sides)
128 = base x height
then if base= 16 and height = 8 then 16 x 8 = 128
thus the base is 16 which is twice the height:8

Jahyib has 421 dollars. He has 152 dollars more than kelsyann. How much money do Jahyib and Kelsyann have altogether?

zaharov [31]

Both of them together have 690 because you subtract 152 from 421 so...

421-152=269

Then add 269 to 421

421+269=690
