What is 1/5 +1/4 please help thank you

1 answer:

5 0

To add fractions, you find the least common multiple.
But, a faster way would be multiply the two denominators together:

x/20 + /20
How many times does 4 go into 20? 5 times. 5 times 1 equals 5.
5/20 + x/20
How many times does 5 go into 20 4 times? 4 times 1 equals 4.

5/20 + 4/20 = 9/20. This is the final answer because it can't be simplified any more.

Larry has a gift card worth 400 for a local entertainment store Movies cost $20 each and newly released video games cost $50 eac

Vikki [24]

Answer:

All are correct.

Step-by-step explanation:

Let x be the number of movies and y be the number of newly released video games.

Larry has a gift card worth 400 for a local entertainment store Movies cost $20 each and newly released video games cost $50 each.

$20x+50y\leq 400$

Larry must purchase at least nine items.

$x+y\geq 9$

Check both inequalities of all given ordered pairs.

For (5,6),

$20(5)+50(6)\leq 400\Rightarrow 400\leq 400$

$5+6\geq 9\Rightarrow 16\geq 9$

Point (5,6) satisfy both inequalities.

For (10,4),

$20(10)+50(4)\leq 400\Rightarrow 400\leq 400$

$10+4\geq 9\Rightarrow 14\geq 9$

Point (10,4) satisfy both inequalities.

For (20,0),

$20(20)+50(0)\leq 400\Rightarrow 400\leq 400$

$20+0\geq 9\Rightarrow 20\geq 9$

Point (20,0) satisfy both inequalities.

For (15,2),

$20(15)+50(2)\leq 400\Rightarrow 400\leq 400$

$15+2\geq 9\Rightarrow 17\geq 9$

Point (15,2) satisfy both inequalities.

Therefore, all combination of movies and newly released video games Larry could purchase using his gift card.

Find the slope of the line through p and q. p(1, −9), q(−3, 2)

attashe74 [19]

To find the slope,we can use the point-slope form:
$y1 - y2 = m(x1 - x2)$
Where m is the slope.

In this case,the equation would be:
-9-2 = m(1-(-3))
-11 = m(1+3)
-11 = 4m
m = -11/4

Therefore the slope is -11/4.

Hope it helps!
