How do you solve that problem

Mathematics

Firlakuza [10]3 years ago

Answer:

x = 13

y = 12

Step-by-step explanation:

4x and 52 have to be equal because they are opposites on the same line. So because of this we can make a simple equation to find x.

4x = 52

divide both sides by 4 and you have x

x = 13

to find y on the other equation, since we know two of the angles, we can add up all three angles and make them equal to 180 (the sum of all angles on a triangle)

90 + 52 + (3y +2) = 180

first subtract 90 and 52 from both sides to leave the equation alone

3y + 2 = 38

second substract 2 to isolate the variable

3y = 36

lastly divide both sides by three

y = 12

Which statement best explains the value of 16 − (−3)?
amm1812

Answer:

The additive inverse of −3 is +3, so 16 − (−3) = 19

negative 6 over 8 minus negative 1 over 8 = negative 5 over 8; therefore, the distance from A to B is absolute value of negative 5 over 8 equals negative 5 over 8 units

Because it is 3 units to the left of 2 on a horizontal number line

Step-by-step explanation:

The answers are the explanation.

Comment on the second question

Note that the second question asks for the distance from -6/8 to -1/8. Ordinarily, the distance from A to B would be computed as B - A. In this set of answer choices, it is computed as |A - B|. In the end, the result is the same.

Personally, I would compute the distance between points on a number line by subtracting the left point from the right point. Here, that would also correspond to B - A.

Comment on choosing 'word' answers

In a set of answers like these, one way to choose answers is simply to eliminate the ones that make a false statement. Often, you are left with only the correct answer choice.

For example, the statement "the additive inverse of -3 is -3" is a false statement, so the first two answer choices can be eliminated. Likewise, the statement 16 -(-3) = 13 is false, so that choice can be eliminated. The one remaining answer is the correct one.

have a good day hope this helped!

Two kilograms of bronze costs £7.20<br> What is the cost of 300g of bronze
sineoko [7]
We know that
1 Kg is equals to--------------> 1000 g
so
 X Kg------------------------> 300 g
X=300/1000------> x=0.30 Kg

if  2 Kg cost--------------> <span>£7.20
  0.30 Kg-------------> X
X=0.30*7.20/2------> x=1.08

the answer is 
</span>£1.08

Which number from the set {0, 2, 4, 6} makes the equation true?
Damm [24]

7x - 3 + 4x = 19

7x + 4x - 3 = 19

11x - 3 = 19            | + 3

11x - 3 + 3 = 19 + 3

11x = 22            | : 11

11x : 11 = 22 : 11

x = 2

Answer B.
