Step-by-step explanation:
-5x+4y=11
substitute for x which is 5
(-5)(5)+4y=11
simplify :
4y-25=11
add 25 on both sides
4y-25=11
+25 +25
the 25 cancels out
so it would be 4y=36
and you divide both sides by 4
4/4 =36/4
which gives you (5,9)
x= 5 , y =9
Ok! At first Laurie has 40 candies since 4 times 10 is 40. then after her dad gives here more, she has 45.
45 is not divisible by six, so we will get a remainder. the closest number to 45 when multiplied by six is 42, and 42/6=7.
Each friends will get 7 pieces, and there will be a remaining of 3 pieces since 45-42=3.
Hope it helped!
When two parallel lines are intersected by another straight line, the inner angles are = 180
so (20x+5) + (24x-1) = 180
solve from there
