I think you wrote something wrong.
Step-by-step explanation:
If Alaina has $7 in her bank account and Joel had $48 in his Joel already has more then Alaina but I will attempt to teach you how to solve these types of problems.
for this example I'm giving Alaina 79 dollars.
First we know were starting with 79 dollars and increasing 6 dollars each day so the equation for this is; y = 6x + 79 that is Alaina's equation.
For Joel our equation will be; y = 8x + 48.
Since they already have 79 and 48 dollars in their bank we put those as our B in the equation cause they are our y-intercepts. (Y = mx + b) Next we know their increasing by 6 and 8 dollars a day so we make those our m. Once we have these equations we can plot them and see where the lines meet. (thats our answer) I plotted them on desmos graphing calculator.
They crossed at (15.5, 172) Which means it will take 16 days for Joel to catch up they will both have 172 dollars in the bank account on the 16th day.
Hope this helps!
Well, all we have to do is add, so:
6 + (-47) =
6 - 47 =
-41

Answer:
36 ft²
Step-by-step explanation:
Scale factor means the side length are multiplied by some value. Here, Jack takes 4 feet and multiplies it by a value of 1 1/2.
The side length he wants is one and a half times the length of his neighbor's.
The 'one' means the side length you started with, and the 'one half' means add half to the original length.
one and a half of four is six. (4 plus half of 4, which is 2, so 4 plus 2)
The box is square, so each side is 6 ft, so the area of the box is 6x6 = 36 ft²
