Answer: 180

Step-by-step Explanation:
The first thing you need to do is know what order to go in, for example ‘pemdas’. (Parentheses, exponents, multiplication, division, additions, and subtraction.)
The first step is going to be the parenthesis so, 8 + 7 = 15. The second step is going to be to distribute, which is multiplication so,
12 x 15 = 180. The last step is to make sure you went through ‘pemdas’ all of the way.

ololo11 [35]
X = apples trees
Y= azaleas


6x + 5y = 219
3x + 4y = 132

-2(3x + 4y = 132)
-6x - 8y = -264
6x + 5y = 219
-3y = -45
-3y/-3 = -45/-3
y = 15

6x + 5y = 219
6x + 5(15) = 219
6x + 75 - 75 = 219 - 75
6x/6 = 144/6
X = 24

The cost for each apple tree is $24 and fit each azalea is $15

Imagine two lines intersect. How can the properties of linear pairs and vertical angles help to determine the angle measures cre
Art [367]
<span>Vertical angles are opposite angles that share only a vertex.
When two lines intersect, we have two sets of vertical angles.

Linear pairs are two angles that form a straight line; when two lines intersect, we have two linear pairs. 

If we know one of the angles formed when two lines intersect, we know that the angle opposite it, the vertical angle, has the same measure.
We also know that the angle beside it, that forms a linear pair, will be supplementary with it (add to 180); this means we can find its measure by subtracting from 180.
The remaining missing angle will be the same as this supplementary angle, since they are vertical angles</span>

To make concrete it take 8 parts crushed gravel, 7 parts water and 5 parts cement mix. A worker needs to make 220 kg of concrete
Romashka-Z-Leto [24]

A complete load of concrete = 8 parts gravel + 7 parts water + 5 parts cement.

Total number of parts in every load = 8 + 7 + 5 = 20 parts

If total load = 220 kg, then       20 parts = 220 kg

Divide each side by  20 :             1 part = 11 kg

gravel   = 8 parts = 8 x 11 kg = <em>88 kg</em>
water    = 7 parts = 7 x 11 kg = <em>77 kg</em>
cement = 5 parts = 5 x 11 kg = <em>55 kg</em>

<u>Check:</u>    88 + 77 + 55 = 220         yay !
