Sue's Sushi placed two orders with its fish supplier. One order was for 15 pounds of salmon and 8 pounds of tuna; the order tota

SVEN [57.7K]

X= salmon cost per pound
y= tuna cost per pound

$15x + $8y= $259
$12x + $6y= $204

Solve for one variable in one equation and substitute it in the other equation.

15x + 8y= 259
subtract both sides by 8y
15x= 259 - 8y
divide both sides by 15
x=(259-8y)/15

Substitute in second equation

12x + 6y= 204
12((259-8y)/15) + 6y= 204
multiply everything by 15 to eliminate fraction

(15)(12(259-8y)/15) + (15)(6y)= (204)(15)
(12*259) + (12*-8y) + 90y= 3060
multiply inside parentheses

3108 - 96y + 90y= 3060
combine like terms & subtract 3108 from both sides

-6y= -48
divide both sides by -6

y= $8 cost of tuna per pound

Substitute y=8 in either equation
15x + 8y= 259
15x + 8(8)= 259
15x + 64= 259
15x= 195
x= $13 cost of salmon per pound

CHECK:
12x + 6y= 204
12(13) + 6(8)= 204
156 + 48= 204
204= 204

ANSWER: One pound of salmon costs $13 and one pound of tuna costs $8.

Hope this helps! :)

The probability of selecting a particular color almond M&M (according to their website) from a bag of M&Ms is listed bel

Anastaziya [24]

Answer:

P(R or G) = 0.3

Step-by-step explanation:

We are given the following in the question:

x: BR Y R BL O G

P(x): 0.1 0.2 0.1 0.2 0.2 0.2

First, we check the nature of distribution.

$\displaystyle\sum p(x) = 0.1 + 0.2 + .1 + 0.2 + 0.2+ 0.2 = 1$

Thus, it is a discrete probability distribution.

We have to evaluate P(R or G)

$\text{P(R or G)} = P(R) + P(G) = 0.1 + 0.2 = 0.3$

Thus, the probability of selecting a red or a green M&M is 0.3

Find the point at which the line x = 5 − t, y = 2 + t, z = 3t intersects the plane x − y + 4z = 13.

Nikolay [14]

The value of the points at which intersection of plane takes place is (x,y,z) = (4,3,3).

According to the statement

we have to find the point which they intersect the given plane.

So, For this purpose, we know that the

The given equations is :

x = 5 − t, -(1)

y = 2 + t, -(2)

z = 3t -(3)

And the given plane is :

x − y + 4z = 13 -(4)

And, the intersection of plane point is :

Put the equations 1 and 2 and 3 in the 4th equations then

(5 − t) - (2 + t) + 4(3t) = 13

3 - 2t + 12t = 13

3 + 10t = 13

10t = 10

Then

t = 1

Put these values in 1 and 2 and 3rd equation then the value of x y z become

x = 5 − t, -(1)

x = 5 -1

x = 4

And

y = 2 + t, -(2)

y = 2 + 1

y = 3

And

z = 3t -(3)

z = 3(1)

z = 3.

The value of (x,y,z) = (4,3,3).

So, The value of the points at which intersection of plane takes place is (x,y,z) = (4,3,3).

What is the answer??(Question 8)

natali 33 [55]

Well for this you can use simple multiplication or you can do a table like this

38.99. keep in mind to go through the
× 82. 2 first before going to 8
______
7798 make sure to add a zero for
+311920 each time you go down
_______
319718.

so you have you're answer but you have to make sure you put your decimal back so since it was in two places move the decimal to the left 2 times then you have your answer

answer- $3,197.18
