Solve For XX=..........................

Answers

Answer 1

Answer:

(3x -5)°+ (2x- 15)°=180°[sum of co- Interrior angles of a triangle is 180°]

or, 3x- 5 + 2x - 15=180°

or,5x - 20 = 180°

or, 5x = 180°+20

or, x = 200÷ 5

•°•x = 40°

Answer 2

Answer:

X = 40

Step-by-step explanation:

3x + 2x -5 -15 = 180

5x + -20 = 180

then u add 20 on both sides

5x + 0 = 200

ya the 0 is not necessary but I was showing u add 20 on both sides lol

then u divide 5 on both sides to get the x by itself

x = 40

Hope this helps dude ^-^

grapes are sold for $3.20 per bag. if you have $12, how many bags of grapes can you buy?

Answers

Answer:

you can buy 4 bags of grapes with $12.

Step-by-step explanation:

Hope this helps :)

Answer:

Step-by-step explanation:

Since we know that one bag of grapes = $3.20, we can divide $12 by $3.20 to get how many bags of grapes you can buy.

12/3.2=3.75.

In the exact amount, you can buy 3.75 bags of grapes. Now you can't buy .75 of a bag. Rounding it, you would have approximiatly bought 4 bags. Reality, you would have bought 3 bags.

Step-by-step explanation:

Find the measures of two supplementary angles if their measures are in the given ratio.
3:7

Answers

Two supplementary angles are in the ratio 3:7. Find the angles ?

Let the two angles be 3x and 7x.

Supplementary angles add up to 180 degrees.

Therefore:

3x + 7x = 180

10x = 180

x = 18

3x = 3 * 18 = 54

7x = 7 * 18 = 126

Measure of angles are 54° and 126°.

What is Supplementary angle?

Sum of two or more angles are 180 degrees then, the angles are called supplementary angle.

Given that;

The ratio of angles are 3 : 7.

Now,

Let the two angles be 3x and 7x.

Since, Supplementary angles are add up to 180 degrees.

So,

3x + 7x = 180

10x = 180

x = 18

So, First angle of supplemental angles = 3x

                                                           = 3 × 18  

                                                           = 54

And, Second angle of supplemental angles = 7x

                                                                   = 7 × 18

                                                                   = 126

Thus, Measure of angles are 54° and 126°.

D) 4 mm

Answers

You have to think of how high the school bus is but I believe it’s A) 4 meters

The dimension of the bus, car, and so on is measured in meters because the 1 or 2 centimeters can be neglected. Then the correct option is A.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The measurement of the object is taken by its length. For example - the distance between the cities is measured in kilometers because the 1 or 2 meters can be neglected.

Similarly, the dimension of the bus, car, and so on is measured in meters because the 1 or 2 centimeters can be neglected.
