Mrs. Sanchez has a bag of assorted nuts that contain almonds, pecans, and walnuts. 1/3 of the nuts are almonds and 3/4 of the remainder are pecans. There are 300 nuts in the bag. How many walnuts are in the bag

Answers

almonds = 1/3*(300) = 100

remainder is 300 - 100 = 200

pecans = 3/4*(200) = 150

walnuts = 300 - 100 - 150 = 50

there are 50 walnuts in the bag

There are 50 walnuts, 100 Almonds, and 150 Pecans.

SOLVE BY SUBSTITUTION:3x-2y=14
y=5x
solve by substitution
x-2y=-2
y=2x+4
solve by elimination
x+2y=-7
x-5y=7
PLEASE HELP WORTH 10 POINTS! AKA SHOW WORK:)

Answers

1)
3x-2y=14
y=5x

So we plug in y=5x into 3x-2y=14

We get:

3x-2(5x)=14
3x -10x=14
-7x=14
x=-2

So we found x, now we need to find y. We can simply plug in x into the equation and get y.

y=5x
y=5(-2)
y=-10

So your answer will be (-2,-10).

2)
x-2y= -2
y= 2x+4

Once again plug in y=2x+4 into x-2y=-2

x-2(2x+4) = -2
x-4x-8=-2
-3x-8=-2
-3x = 6
x= -2

Now we plug back in x and solve for y :)

y=2x+4
y=2(-2)+4
y=-4+4
y=0

So our solution would be (-2,0).

3)
x+2y=-7
x-5y=7

Multiply the second equation by -1

-x+5y=-7

Now add that equation with the other one:

x+2y=-7
+
-x+5y=-7
-----------------
7y=-14
y=-2

Now plug in y=-2 and solve for x

x+2y=-7
x+2(-2)=-7
x+(-4)=-7
x-4=-7
x=-3

So your solution would be (-3,-2).

1)

$3x-2y=14\n \n y=5x$

We know y's value. Let's plug it in the equation.

$y=5x\n \n 3x-2\cdot (5x)=14\n \n 3x-10x=14\n \n -7x=14$

Divide both sides by -7.

$x=-2$

Now we have x's value. Let's plug it in the equation to find y.

$x=-2\n \n y=5x\n \n y=5\cdot -2\n \n y=-10$

Solution,

(-2, -10)

2)
$x-2y=-2\n \n y=2x+4$

Again we have y's value. Let's plug and solve.

$y=2x+4\n \n x-2\cdot (2x+4)=-2\n \n x-(2\cdot 2x+2\cdot 4)=-2\n \n x-4x-8=-2\n \n -3x-8=-2\n \n -3x=-2+8\n \n -3x=6\n \n x=\frac { 6 }{ -3 } \n \n x=-2$

Now we have x's value let's solve for y.

$x=-2\n \n y=2x+4\n \n y=2\cdot (-2)+4\n \n y=-4+4\n \n y=0$

Solution,

(-2, 0)

3)

$x+2y=-7\n \n x-5y=7$

Let's first multiply the first equation by -1

$-1\cdot (x+2y)=-1\cdot -7\n \n -x-2y=7$

Then let's add these new equation and the second equation.

$-1\cdot (x+2y)=-1\cdot -7\n \n -x-2y=7\n \n x-5y=7\n \n (-x-2y)+(x-5y)=7+7\n \n -x+x-2y-5y=14\n \n -7y=14\n \n y=\frac { 14 }{ -7 } \n \n y=-2$

Now we have y's value let's plug it and solve for x.

$y=-2\n \n x+2y=-7\n \n x+2\cdot (-2)=-7\n \n x-4=-7\n \n x=-7+4\n \n x=-3$

Solution,

(-3, -2)
