The larsen family bought 3 jumbo burritos and 2 regular burritos for $13.65. the russo family bought 5 jump burritos and 2 regular burritos for $20.23. does a jumbo burrito cost more than $3.00? enter and solve a system of equations to justify your answer. a jumbo burrito (does/does not) cost more than $3.00 the system [blank] = 13.65 models this situation, where x is the price of a jumbo [blank] = 20.23 burrito and y is the price of a regular burrito. the solution is (blank, blank), so a jumbo burrito costs $[blank]

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
