Answer:
(1)
compound amount = 802.5 $
invest earned = 52.5 $
Step-by-step explanation:
total amount = 10000 $
let amount x invested in ventures A and remaining (1000-x) on ventures B
now,
6x/100 +23/400(1000-x ) = 588.75
{24x+23(1000-x)}/400 =588.75
x=235500-230000
x=5500
Amount invested on A = 5500$
Amount invested on B = 4500$
(2)
principle=750$
time= 1 year
effective invest rate = 7%
a) compound amount = p(1+(r/w)^t
=750{1+(7/100)}^1
=802.5$
b) invest earned = 802.5-700 = 52.5$
Here is the answer. Since the given values are in the "gram" units, and the question is asking if how many grams lighter is the box, what we are going to do is just to convert the units so that it would be the same. So 150 grams minus 138 grams is 12 grams. So it is 12 grams lighter, and 12 grams is equivalent to 12,000 milligrams. Hope this answers your question.
Is this what you mean? 3x+4x+6=13
Ok if this is it then you combine like terms.
In this case our like terms are 3x and 4x.
That will give us:
7x+6=13
Now subtract 6 from each side.
7x= 7
Divide each side by 7
X= 1
575 / 14
Use easy multiples of 14 that do not exceed 575. Use 10.
(1) 14*10 = 140 575 -140 = 435
(2) 14*10 = 140 435 - 140 = 295
(3) 14*10 = 140 295 -140 = 155
(4) 14*10 = 140 155 - 140 = 15
Now you cannot use another 10*14. Then just divide 15 by 14 which gives 1 and have remainder 1
(5) 15/14 = 1
15 - 14 = 1 = Remainder
Then, the sum of the partial quotients is 10+10+10+10+1 = 41; and you have remainder 1, therefore 575 = 41*14 + 1
And the result of the division is 575/14 = 41 plus remainder 1
