Answer:

Using a system of equations, it is found that:

In our system, we have that:

Those 3 compromise 97% of the flavors, hence:

[tex]x + y + z = 97[/tex]

Vanilla sells 10% more than twice strawberry, hence:

[tex]x = 10 + 2y[/tex]

Chocolate sells 7% more than vanilla, hence:

[tex]z = x + 7[/tex]

Since [tex]x = 10 + 2y[/tex]

[tex]z = 10 + 2y + 7[/tex]

[tex]z = 2y + 17[/tex]

Replacing in the first equation, we can solve for y:

[tex]x + y + z = 97[/tex]

[tex]10 + 2y + y + 2y + 17 = 97[/tex]

[tex]5y = 70[/tex]

[tex]y = \frac{70}{5}[/tex]

[tex]y = 14[/tex]

With y, we can solve for x and for z.

[tex]x = 10 + 2y = 10 + 2(14) = 38[/tex]

[tex]y = 2y + 17 = 2(14) + 17 = 45[/tex]

Answer:

15

Step-by-step explanation:

It does not divide evenly, but there are 15 groups of 6 in 95.

Answer:

The first equation does not have any, as x^2 always makes the values postive, which causes it to always be greater than 0.

Step-by-step explanation:

The second inequality is x is less than or equal to 4, and greater than or equal to negative 3.

The third inequality is x is greater then or equal to negative 6, and less than negative 3.

The fourth inequality was a bit strange, it gave results that were difficult to graph. However, it seems m is less than or equal to negative 1.2, and greater than or equal to 8.2.

The fifth inequality is x is greater than or equal to negative 2, and less than or equal to 7/2.

Hope this helps!

Answer:

(20÷100)×96=19.2

(15÷100)×75=11.25

Answer:

A = 480

B = 500

Step-by-step explanation:

Find A and B??

.

20% of A = 96

[tex]\sf{20\% \times A = 96}[/tex]

[tex]\sf{ \frac{20}{100} \times A = 96}[/tex]

[tex]\sf{A = 96 \div \frac{20}{100} }[/tex]

[tex]\sf{A = 96 \times \frac{100}{20} }[/tex]

[tex]\sf{A = \frac{9600}{20} }[/tex]

[tex]\green{\sf{A = 480}}[/tex]

.

15% of B = 75

[tex]\sf{15\% \times B = 75}[/tex]

[tex]\sf{ \frac{15}{100} \times B = 75}[/tex]

[tex]\sf{B = 75 \div \frac{15}{100} }[/tex]

Answer:

See answer below.

Step-by-step explanation:

1. Start at point (0,0), This point is where the x-y-axis meet.  Do not put a dot

   there because this is your starting point.

2.  Move to the left over to point -1 3/4 . This place is between -1 and -2, and

     closer to -2 because the point is -1 .75.  Remember this point is not on the

     graph.  

3.  Now move up from that point to 4.5 and put a dot at that place.  The point is in the Q II ,  to the left top.  

Let x be the needed volume of 50% antifreeze solution. x gallons of this solution contains 0.50x gal of antifreeze.

Mixing this amount with 90 gal of 25% solution makes a total volume of (x + 90) gal of solution.

90 gal of 25% solution contains 0.25 (90 gal) = 22.5 gal of antifreeze.

The new mixture would then consist of (0.50x + 22.5) gal.

If its concentration of antifreeze is supposed to be 40%, then

(0.50x + 22.5)/(x + 90) = 0.40

Solve for x :

0.50x + 22.5 = 0.49 (x + 90)

0.50x + 22.5 = 0.49x + 44.1

0.01x = 21.6

x = 2160

Answer:

x = 12.633, -0.633

Step-by-step explanation:

x^2 -12x + 36 = 44

the underlined part is (x - 6) ^2

(x - 6)^2 = 44

(x - 6) = ± [tex]\sqrt{44}[/tex]  (both positive and negative)

(x - 6 ) = + 6.6332495807108

x = 12.6332495807108 = 12.633

(x - 6 ) = - 6.6332495807108

x = - 6.6332495807108 + 6

= -0.6332495807108 = -0.633

Answer:

Paula's dog weighs 57lbs and Carla's dog weighs 19lbs

Step-by-step explanation:

So Paula's dog will be "p" and Carla's dog will be "c"

This means p = 3c and that p + c = 76

Replace p with 3c

3c + c = 76

4c = 76

c = 19

Now solve for p

p + (19) = 76

p = 57
