Answer:

x = 6

Step-by-step explanation:

Love proportions!

3x+2(x+6) = 35(21)

21(3x+2) = 35(x+6)

63x + 42 = 35x + 210

28x = 168

x = 6

2. 3.55$ would be left

Step-by-step explanation:

1. 300-140=160

160-25=135

135/11.95=11.297

2. 11.95x11=131.45

131.45+25=156.45

156.45+140=296.45

300-296.45=3.55

kow [346]

Answer:

Step-by-step explanation:

a)

Smallest number of equations required are:

N=2(forR^2)

Let equations are

2x+3y=13\\7x+y=17

b)

Yes we can add one more equation

c)

We can add infinite such equations so that solution remains same.

d)

General form of such equations are called inconsistent equations

Can I get an example of systems of equations that represent the solution of this situation below? Thank you! ^ ^
Alenkinab [10]

Answer:

1x+ 1y =11

10x + 5y = 80

x = the cost of a taco = $5

y = the cost of a burrito = $6

Step-by-step explanation:

x = the cost of a taco

y = the cost of a burrito

1x+ 1y =11

10x + 5y = 80

rearange 1st equation as y = 11 -x and plug in into the 2nd one for y:

10x + 5( 11-x) = 80 distribute left side

10x + 55 - 5x = 80 combine like terms

10x - 5x = 5x

5x + 55 = 80 subtract 55 from both sides

5x = 80 - 55

5x = 25 divide by 5

x = 5

plug in for y in 1st equation y = 11--x =11-5 = 6

Suppose I pick a jelly bean at random from a box containing two red and ten blue ones. I record the color and put the jelly bean
Lubov Fominskaja [6]

Answer:

The probability of getting a red jelly bean both of the times is 0.028.

Step-by-step explanation:

First we have that in the box are 12 jelly beans having 2 red and 10 blue. The probability of getting one of the red jelly beans are the sum of the probability of the 2 red jelly beans, that is:

ProbabilityRed=\frac{1}{12} +\frac{1}{12}=\frac{2}{12}

Now we can calculate the probability of getting the red jelly bean twice, this will be the product of the probability of getting each one, is the same probability for the second chance because we are getting the jelly bean back in the box, this is:

ProbabilityBothRed=\frac{2}{12} *\frac{2}{12}=\frac{4}{144}  =\frac{1}{36} =0.028

Now we have that the probability of getting a red jelly bean both of the times is 0.028.
