Her brother sent C. 490 messages.
In order to find this, we need to set it up as a proportion. Once we have done that, we can cross multiply and solve for the unknown variable.
(4/7) = (280/x) -----> Cross multiply.
4 * x = 7 * 280
4x = 1960
x = 490
2x-5y+68x-3y-68=0
70x-8y-68=0
solve from there
We can’t measure these. How long is each of them
