Answer:
Total money = $30,00,000
Step-by-step explanation:
Given:
4/5 money spend on house
3/4 remaining money spend on luxury yacht
2/3 remaining money spend on trip to space
Remaining $50,000 to charity
Find:
Total money
Computation:
Assume Total money = x
So,
Spend on house = [4x/5]
Spend on luxury yacht = [x-4x/5]3/4 = 3x/20
Spend on trip to space = [x/5-3x/20]2/3 = x/30
Remaining money = x/20 - x/30 = x/60 = $50,000
So,
x/60 = $50,000
x = $300,000
Total money = $30,00,000
Answer:
B.
Step-by-step explanation:
Area is width times height.
(5p-7)(3p+4)
Multiply using FOIL method
(First, outer, inner, last)
(5p*3p) + (5p*4) + (-7*3p) + (-7*4) =
15p² + 20p -21p - 28 =
15p²-p -28 =
B is the closest one. They might have made a typo.
Answer:
x+3y=-9
Step-by-step explanation:
-2(x+3y)=18
x+3y=18/-2
x+3y=-9
Answer:
y=4x-5.
Step-by-step explanation:
slop-interception form of the required line is y=kx+b, where k - slop, b - intercept;
1) to find value of k:
if the required line is parallel to the given line, then slop of the given line = slop of the required line, it means k=4 and the required line is y=4x+b;
2) to find the value of 'b':
if to substitute the given coordinates into the equation of the given line, then:
15=4*5+b, b= -5.
3) finally, y=4x-5
