Hey there! :)
Answer:
Anna's number = 13.
Olga's number = 52.
Step-by-step explanation:
We can express this situation as an equation to solve for both of their numbers.
Let x be Anna's number
Let 4x be Olga's number
Their numbers sum up to 65, therefore:
4x + x = 65.
Begin by combining like terms:
5x = 65
Divide both sides by 5:
5x/5 = 65/5
x = 13 = Anna's number.
Find Olga's number by plugging 13 into 4x:
4(13) = 52. This is Olga's number.
(-4)(5)+8= -12Then next one is -14
