  We prove quantitative, one-weight, weak-type estimates for maximal operators,
singular integrals, fractional maximal operators and fractional integral
operators. We consider a kind of weak-type inequality that was first studied by
Muckenhoupt and Wheeden and later by Cruz-Uribe, Martell and Perez. We obtain
quantitative estimates for these operators in both the scalar and matrix
weighted setting using sparse domination techniques. Our results extend those
obtained by Cruz-Uribe, Isralowitz, Moen, Pott, and Rivera-R\'ios for singular
integrals and maximal operators when $p=1$.
