Answer:
Step-by-step explanation:
you
60 +14*number of weeks
sister
120+10*number of weeks
let x be the number of weeks until they have the same amount of money
60+14x = 120+10x ; isolate like terms
14x -10x = 120-60
4x = 60; divide both sides by 4
x= 15 weeks
120+10*15 = 120+ 150 = $270 will be the amount they will have the same
Answer:
I don’t know just here for the points just kidding it’s actually 5,000 in total
Answer: India has 12 times the population of spain
It's an arithmetic progression with first term = 8 and common difference d =2:
so the next term is 14 + 2 = 16
Answer:
Step-by-step explanation:
step 1
Find the measure of angle EFD
In this problem I will assume that ABCD is a parallelogram
In a parallelogram opposite angles are congruent and consecutive angles are supplementary
so
--- > given problem
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
so
In the triangle EFD
substitute the given values
step 2
Find the measure of angle EFB
we know that
---> by supplementary angles
we have
substitute
step 3
Find the value of x
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
so
In the triangle EBF
we have
substitute
solve for x
