Answer:
one hundred twenty million five hundred forty thousand
Answer: C
Step-by-step explanation: They are never the same
Answer:100-7x
Step-by-step explanation:
If x people are coming, he will spend the following
Sandwiches =2.50 × x= 2.50x
Drinks = 1.50 × x= 1.50x
Gift bags =3 × x=3x
Money left
Sandwiches = 50-2.50x
Drinks =25-1.60x
Gift bags = 25-3x
Total money left = 50-2.50x+25-1.50x+25-3x
=50+25+25-2.50x-1.50x-3x
=100-7x
BD = 2x-4
But it's also BE - CE + CD
BE is 3x-1
CE is 2x-3
CD is 2
so
BD = 3x-1 -(2x-3) +2
simplified
BD = 1x +4
since BD = BD (obviously), we can also say that the righthand sides of the two equation must be equal
2x -4 = 1x +4
let's solve for x and that put it into either of the 2 equations.
2x -4 = 1x +4
subtract 1x on both sides
x -4 = 4
add 4 on both sides
x = 8
substitute x for its value in 2x -4 = 1x +4
(this way we double check BD in two expressions at once. the equation should come out true, meaning same value for BD in each expression. both sides should be equal).
2*8 -4 = 1*8 +4
12 = 12
seems true
BD is safely 12
