Jimmy has 2 times as many twenty-five paisa coin as fifty-paisa coins . If he has total of Rs. 3.00, how many coins of each kind
Ierofanga [76]

Answer:

x = 6

y = 3

6 twenty-five paisa coin

3 fifty-paisa coins

Step-by-step explanation:

x -----> twenty-five paisa coin

y -----> fifty-paisa coins

0.25x + 0.5y = 3.00        per 100

x = 2y

25x + 50y = 300

x = 2y

25(2y) + 50y = 300

50y + 50y = 300

100y = 300

y = 300/100

y = 3

x = 2y

x = 2(3)

x = 6

on the first play of a game , a football team gained 23 yards and then lost 10 yards due to penalty during the second play the t
zepelin [54]
-1 Let's say the set of downs starts at the 20 yard line (maybe the kicking team kicked deep, the receiving team took a knee and so play starts at the 20).
Ok - we're at the 20. First down - they advance 5 yards. So we're now at the 25. We can write that mathematically as:
20
+
5
=
25
So the second play they get sacked deep and lose 6 yards. So we subtract 6:
25
−
6
=
19
So what's the change in yardage for the 2 plays? We are on the 19 and started at the 20, so we can write:
19
−
20
=
−
1
and this makes sense because we know we advanced 5 and fell back 6

1/4x + x = -3+ 1/2x, what is x?
USPshnik [31]

Answer:

x = -4

Step-by-step explanation:

Solve for x:

(5 x)/4 = x/2 - 3

Put each term in x/2 - 3 over the common denominator 2: x/2 - 3 = x/2 - 6/2:

(5 x)/4 = x/2 - 6/2

x/2 - 6/2 = (x - 6)/2:

(5 x)/4 = (x - 6)/2

Multiply both sides by 4:

(4×5 x)/4 = (4 (x - 6))/2

(4×5 x)/4 = 4/4×5 x = 5 x:

5 x = (4 (x - 6))/2

4/2 = (2×2)/2 = 2:

5 x = 2 (x - 6)

Expand out terms of the right hand side:

5 x = 2 x - 12

Subtract 2 x from both sides:

5 x - 2 x = (2 x - 2 x) - 12

5 x - 2 x = 3 x:

3 x = (2 x - 2 x) - 12

2 x - 2 x = 0:

3 x = -12

Divide both sides of 3 x = -12 by 3:

(3 x)/3 = (-12)/3

3/3 = 1:

x = (-12)/3

The gcd of -12 and 3 is 3, so (-12)/3 = (3 (-4))/(3×1) = 3/3×-4 = -4:

Answer:  x = -4

The difference between the roots of the quadratic equation x2+x+c=0 is 6. Find c.
NemiM [27]
We have that
x_{1} - x_{2} = 6
Let y be the first root, then y - 6 will be the second one. Since both roots make the quadratic equation equal to 0, we have that:
y^{2}  + y + c =  (y - 6)^{2}  + (y - 6) +c
Solve for y:
y^{2} +y +c = y^{2} - 12y + 36 + y - 6 +c \\ y + 12y - y = 30 \\ y =  \frac{5}{2}
Plug in y = 5/2 into original quadratic equation and solve for c:
(  \frac{5}{2}) ^{2} +  \frac{5}{2}  +c = 0 \\  c= - \frac{5}{2}  -  \frac{25}{4}  \\ c = - \frac{35}{4}
So, the answer is c = -35/4
