Answer:
227 dollers
Step-by-step explanation:
multiply 3.49 and 15 to get 52.35
multiply 4.99 and 35 together to get 174.65
then add 52.35 and 174.65 to get the total dollors amounts of 227

To better understand the problem see the attached figure
we have
![\frac{2}{5}+p=\frac{4}{5}+\frac{3}{5}p](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D%2Bp%3D%5Cfrac%7B4%7D%7B5%7D%2B%5Cfrac%7B3%7D%7B5%7Dp)
Multiply by
both sides
![5(\frac{2}{5}+p)=5(\frac{4}{5}+\frac{3}{5}p)](https://tex.z-dn.net/?f=5%28%5Cfrac%7B2%7D%7B5%7D%2Bp%29%3D5%28%5Cfrac%7B4%7D%7B5%7D%2B%5Cfrac%7B3%7D%7B5%7Dp%29)
![2+5p=4+3p](https://tex.z-dn.net/?f=2%2B5p%3D4%2B3p)
Group terms that contain the same variable p and move the constant to the other side of the equation
![5p-3p=4-2](https://tex.z-dn.net/?f=5p-3p%3D4-2)
![2p=2](https://tex.z-dn.net/?f=2p%3D2)
![p=1](https://tex.z-dn.net/?f=p%3D1)
Answer:
I think the right answer would be 7
Step-by-step explanation:
We got-ta use the equation: CA * BA = DA²
CA = 15 + BA
DA² = 8² = 64
=> (15 + BA) BA = 64
Subtract 15 from each side:
BA(BA) = 49
BA² = 49
Now take the square root of each side
BA = 7
Hope this helps!
to find the x-intercept of a function, we simply set y = 0 and then solve for "x", so, let's first find the equation of it and then set y = 0.
