Answer:
7.8y - 26.2
Step-by-step explanation:
Answer:
35 : 7
5 : 1 ( if u need ur answer in simplest form )
Step-by-step explanation:
When the question asks to compare the like terms of an equation, they mean to solve the equation and put the like terms or the terms that are similar in that equation.
Lets look at some examples of what like terms are:
2x+5y =?
To solve this is quite simple. 2x+3y = 5xy. Just add the 2 and 3 to get 5 and just place the xy in the end of the equation.
The pairs of like terms here are <em>x</em><em> </em><em>and</em><em> </em><em>y</em><em>,</em><em> </em><em>2</em><em> </em><em>and</em><em> </em><em>5</em>
12x-3y=?
To solve this is also quite simple. 12x-3y = 9xy Just subtract the 12 from 3 to get 9 and add the unknown values which are the x and y in the end of the equation.
The pairs of like terms here are x and y and 12 and 3.
<em>The</em><em> </em><em>like</em><em> </em><em>terms</em><em> </em><em>can </em><em>be</em><em> </em><em>the</em><em> </em><em>unknowns</em><em> </em><em>put</em><em> </em><em>together</em><em>,</em><em> </em><em>and</em><em> </em><em>the</em><em> </em><em>known</em><em> </em><em>values</em><em> </em><em>put</em><em> </em><em>together</em><em>.</em><em> </em>
Let's look at what the question asks for.
43y+22y=?
In this equation the unknown is <em>y</em><em>.</em><em> </em>The other known values are 43 and 22.
To solve this:
43+22 = 65
x+y = xy
Values are 65 and y
Add all values to make the equation.
43y+22y= 65y
1st question
explanation: to find the hypotenuse for the 45-45-90, you need to multiply the leg (1) by √2
ans: √2
2nd question
explanation: to find the long leg for the 30-60-90, you need to multiply the short leg (1) by √3
ans: √3
70% of 14
10%=14/10=1.4
70%=1.4x7=9.8
