Jamie, Lily, and Alice collectively weigh 192 pounds. Lily is 3 times as heavy as Jamie, and Alice is 11 pounds. Lighter than Li

lbvjy [14]

Answer:

Alice is 47 pounds havier than Jamie.

Step-by-step explanation:

Let be "j" the weight in pounds of Jamie, "l" the weight in pounds of Lily and "a" the weight in pounds of Alice.

Based on the data given in the exercise, we can know that:

$j+l+a=192$ [Equation 1]

$l=3j$ [Equation 2]

$a=l-11$ [Equation 3]

Solve "j" from the Equation 2:

$j=\frac{l}{3}$

Substitute this equatio and the Equation 3 into the Equation 1 and solve for "l":

$\frac{l}{3}+l+(l-11)=192\\\\\frac{7}{3}l=203\\\\l=(203)(\frac{3}{7})\\\\l=87$

Substitute the value of "l" into the equation $j=\frac{l}{3}$ to find "j":

$j=\frac{87}{3}=29$

Substitute the value of "l" into the Equation 3 to find "a":

$a=87-11=76$

Subtract the weight of Jamie from the weight of Alice in order to find how much heavier is Alice than Jamie:

$76lb-29lb=47lb$

Alice is 47 pounds havier than Jamie.

BRAINLIEST 100 PTS MATH HELP PLEASE

denis-greek [22]

Answer:

they are 10km 32 degrees far from each other

Step-by-step explanation:

scott - 100km - 30 degrees

spork - 110km - 62 degrees

how far = difference between them

as spork's distance and degrees are greater than scott we substract Scott's from spork's

110 - 100 = 10 km

62 - 30 = 32 degrees

they are 10km 32 degrees far from each other
