If 1 angle is 55 and another is 55 add 20 (75) if you added them together it would be 130 so do 180 - 130 hope this helped!!
Answer:
3w < 18
Step-by-step explanation:
To do 3 times if you put 3 against a variable that means to multiply. Since a number is unknown it turns into variable which is w in this case. Then less than 18 to do the less than symbol, think of them like crocodile they always eat the bigger number and since 3w is less than 18 the croc < eats 18. Thats just an easy way of remembering. Hope this helps :)
Answer:
A. Multiply 3x−3y=1 by 2, and multiply −2x+4y=2 by 3.
Step-by-step explanation:
Given
Required
A good first step
A good first step is to eliminate x and this is done as follows:
Multiply by 2 (gotten from coefficient of x in the second equation)
Multiply by 3 (gotten from coefficient of x in the first equation)
This gives:
Add both equations
<em>Hence (a), is true</em>
