we have 3 boxes and they are equal to 2 circles, if each circle is equal to 1, what is the value of 1 box?
mario62 [17]

Answer:⬛️=.667 (.66 repeating)

Step-by-step explanation) you can set up the equation:

3x=2y

(using x for squares and y for circles).

we know the value of the circles is 1, so plug 1 in for y

3x=2(1) , simplify

3x=2

now get x by itself by dividing both sides by 3

x=2/3

x=.66

5/6(2x+12)-8=4-(x+1)
alekssr [168]

For this case we have the following equation:

\frac {5} {6} (2x + 12) -8 = 4- (x + 1)

We apply distributive property on the left side of the equation:

\frac {5 * 2} {6} x + \frac {5 * 12} {6} -8 = 4- (x + 1)\\\frac {10} {6} x + \frac {60} {6} -8 = 4- (x + 1)

We simplify the left side of the equation:

\frac {5} {3} x + 10-8 = 4- (x + 1)

Different signs are subtracted and the major sign is placed.

\frac {5} {3} x + 2 = 4- (x + 1)

On the right side we must take into account that:

- * + = -

So:

\frac {5} {3} x + 2 = 4-x-1\\\frac {5} {3} x + 2 = 3-x

We add x to both sides of the equation:

\frac {5} {3} x + x + 2 = 3\\\frac {5 * 1 + 3 * 1} {3} x + 2 = 3\\\frac {5 + 3} {3} x + 2 = 3\\\frac {8} {3} x + 2 = 3

We subtract 2 from both sides of the equation:

\frac {8} {3} x = 3-2\\\frac {8} {3} x = 1

We multiply by 3 on both sides of the equation:

8x = 3

We divide by 8 on both sides of the equation:

x = \frac {3} {8}

Thus, the solution of the equation is:

x = \frac {3} {8}

Answer:

x = \frac {3} {8}

A linear function is a function that creates a straight line when graphed. The difference between this graph and others is that this function is constant instead of curved. I’d like to see an example of this in the real world as a relationship between profit and merchandise.A quadratic function is a function that has multiple variables allowing the graph to curve. The difference between this function and the others is that this function is squared allowing for a greater curve that looks like a U. I’d like to see a example of this in the real world as missiles being launched since the curve is similar.A exponential function is a function in which the function grows at a fast rate. The difference between this function and the others is that this function curves in a constant rate then the x increases continuously. I’d like to see an example of this in the real world as the interest in a bank since it increases per month.

Use Boolean algebra to simplify the given Boolean expression. Determine the minimum (i.e. simplest) expression. F(A, B, C) = A.B
klasskru [66]

Answer:C

Step-by-step explanation:

A.B.C+A.B'.C+A'.B.C+A.B.C'

By distributive law : A.B.C+A.B.C' = A.B(C+C')

By complement law: C+C'=1, so

A.B(C+C')=A.B

Therefore the answer will be A.B'.C+A'.B.C+A.B
