Answer:
This equation is incorrect. The equation simplifies to -3=4 which is incorrect.
Step-by-step explanation:
3(-3)=-9. 3(2)=6
-9+6=-3
-3=4 FALSE
Set up a proportion having 120 over 3 = x over 8
cross multiply with 3x = 960
then divide by 3
the answer is 320 miles
Answer:
I'll choose the first one but don't know the right one
Answer:
$15 is 37.5% of $40.
Step-by-step explanation:
Ok so there's 5 sides
let's find interior angle sum
formula is S=180(n-2)
n in this case is 5 since there are 5 sides
S=180(5-2)
S=180(3)
S=540
so now add the 5 angle lengths up to 540
5x+2+10x-3+7x-11+13x-31+8x-19=540
43x+-62=540
+62 +62
43x=602
divide both sides by 43
x=14!!!!!
