Heya!!!
Answer to your question:
Let Adam's points be x.
Nick has points =7200=20%of x+x
20/100 *x + x=7200
x/5 +x=7200
6x/5=7200
x= 7200*5/6
x=6000
Adam has 6,000 points.
Hope it helps *_*
Answer:
t=5.25x
Step-by-step explanation:
since X equals the number of egg cartons sold then we would have to multiply that by how much one egg carton costs (5.25$ each)
so if they sold 3 egg cartons the equation would be t=5.25*3.
(putting a variable next to a number means your multiplying it)
I hope I explained that clearly enough :P
Answer:
x + y = 14 -----------(1)
----------------(2)
The above is the required system of equation, where,
x = no. of cans of soup Robert purchased
y = no. of cans of frozen dinner Robert purchased
c = amount of sodium (in mg) which each can of frozen dinner contains
Step-by-step explanation:
Let, Robert purchased x number of cans of soup and y number of cans of frozen dinner and each can of frozen dinner contains c mg of sodium.
Then, according to the question,
x + y = 14 -----------(1)
and
----------------(2)
EB * AE = DE *EF
x+3 *3 = 6*x-2
simplify:
3x+9 = 6x-12
subtract 3x from each side
9 = 3x -12
add 12 to each side
21 = 3x
divide both sides by 3
x = 21/3
x = 7
replace x with 7 to find EB
EB = 7+3 = 10 cm
