Because like terms you add or subtract together to make it easier to do the problem. just like you do with whole numbers. you add an subtract to make the answer simpler.

Adding and subtracting like terms is the same as adding and subtracting of numbers, i.e., natural numbers, whole numbers and integers. So, the sum and the difference of several like terms is another like term whose coefficient is the sum and the difference of the coefficient of several like terms.

Answer:

Step-by-step explanation:

Step 1: Sum of angles on a straight line is 180

Step 2:

2x + 25 + y = 180

2x + y = 180 - 25

2x + y = 155 (1)

Step 3:

3x - 10 + y = 180

3x + y = 180 + 10

3x + y = 190 (2)

Step 4: Substract equation 1 from 2

3x + y - 2x - y = 190 - 155

x = 35

Step 5:

Substitute x in equation 1 to find y

2x + y = 55

2(35) + y = 155

70 + y = 155

y = 155 - 70

y = 85

Firewood can be sold in cords. the wood is cut into equal lengths and stacked evenly in a rack. which geometric shape can be use

Nadya [2.5K]

To estimate the volume of the chord of wood, since the wood exists cut into equal lengths and stacked evenly in a rack then we can use a cylinder as a model.

<h3>What is a cylinder?</h3>

In mathematics, a cylinder exists as a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance. These bases exist normally circular (like a circle) and the center of the two bases exists joined by a line segment, which exists named the axis.

A cylinder exists as a closed solid that contains two parallel circular bases joined by a curved surface.

To calculate the volume of the chord of wood, since the wood exists cut into equal lengths and stacked evenly in a rack then we can use a cylinder as a model.

If RH = 10 units, HT = 16 units, and GH = 8 units, what is the length of line segment HJ?

Dominik [7]

Answer:

$HJ=20\ units$

Step-by-step explanation:

<u><em>The complete question is</em></u>

RT and GJ are chords that intersect at point H. If RH = 10 units, HT = 16 units, and GH = 8 units, what is the length of line segment HJ? 18 units 20 units 26 units 28 units

we know that

The <u><em>intersecting chords theorem</em></u> is a statement that describes a relation of the four line segments created by two intersecting chords within a circle. It states that the products of the lengths of the line segments on each chord are equal

In this problem

$(RH)(HT)=(GH)(HJ)$

substitute the given values

$(10)(16)=(8)(HJ)$

solve for HJ

$HJ=160/8\\HJ=20\ units$

Adding proper fractions .. 10/12+6/12=need help

mixas84 [53]

Adding fractions is easy when you get the rules...
10/12 + 6/12...
add the numerator which is the top, and keep the denominator which is the bottom.
10/12 +6/12 = 16/12
change that into a mixed number
16/12 = 1 4/12 which is simplified to 1 1/3
hope this helps
