The equation you would write would be:
2x+34=187<span />
If we got 560 pounds for 800 dollars and x pounds for 1 dollar, this means that x = 560*1/800 <=> x = 56/80. Performing the calulation we get that x = 0.7
Mn - 4m - 5n + 20
In this, mn and -4m have a common factor; m. So we can take that out to make it:
m(n-4) -5n + 20
Now, -5n + 20 also has a common factor which is 5, because 20/5 gives you 4, and 5/5 equals 1. So we can talk out that -5 (it doesn't need to be negative, but negatives on variable, no gusta). So you'd get
m(n-4)-5(n-4) OR m(n-4)+5(-n+4)
Answer:
No
Step-by-step explanation:
In order for three sides to make a triangle, if any two sides are added together, their sum should be greater than the third side:
=><u> 5 + 7 = 12 < 13 (DOES NOT check off the rule)</u>
=> 7 + 13 = 20 > 5 (Checks off the rule)
=> 5 + 13 = 18 > 7 (Checks off the rule)
As shown, even though 2 of the statements check off the rule the third one does not, this means that the sides don't make a triangle.
Hope this helps!
