First:

Change the fraction to 2 and 2/4's

Second: Get rid of the whole number

there is 4 one fourths in a whole number so there is 8 fourths in 2 and then the other two fourths would be 2 more so therefore

8+2=10

x = 42

Step-by-step explanation:

3x + 12 + x = 180                        3x + 12

3x + x = 4x                                 3 x 42 + 12

4x + 12 = 180                              126 + 12

    - 12      -12                                 = 138

4x = 168

x = 42

Answer:

x=42

3x+12=138

Step-by-step explanation:

4x+12=180

Answer:

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by ∛

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.

Step-by-step explanation:

The value of a and b from the coordinates are 3 and 5 respectively

The formula for finding the midpoint of two coordinates is expressed as;

M(x, y) = {x1+x2/2, y1+y1/2}

Given the following coordinates

M(a, 4)

A(1,3)

B(5,b)

Using the formula

a = 1+5/2

a = 6/2

a = 3

Similarly

4 = 3+b/2

8 = 3+b

b = 8-3

b = 5

Hence the value of a and b from the coordinates are 3 and 5 respectively

Answer: 69 and 32

Step-by-step explanation: 7 squared is 49 and 2 x 10 is 20 and 49 + 20 is 69. 3/4 x 16 is 48/4 and when you simplify that you get 12 and 5/2 x 8 is 40/2 which is 20 so 12 + 20 is 32.

x+14=x14

Answer:

(x+14)=14

(x+14)-14=0

-14x-196=0

-14x=196

x= -14

Step-by-step explanation:

In order to find the number of solutions, we have to expand both sides out first.

\(3(x - 2) + 7x = \frac{1}{2} (6x - 2)\)

First, expand 3(x-2), which will obtain 3x-6.

Next, expand (1/2)(6x-2), which gives 3x - 1.

The result at this point should be as shown below:

\(3x - 6 + 7x = 3x - 1\)

Now, we would shift all x terms to the left and all number terms to the right.

\(3x + 7x - 3x = - 1 + 6\)

After simplifying, the final equation would be:

\(7x = 5\)

This is a linear equation and it has one solution.

Answer:

A) 25

Step-by-step explanation:

sides of top square are all 13 and sides of bottom square are all 12

we now have the hypotenuse (13) and another side length of the triangle (12) using a^2+b^2=c^2 we can find the side of the square then its area.

144+b^2=169

b^2=25

b=5, which means the smallest square's sides are all 5 making it have an area of 25

Answer:

mDF = 90°

(Assuming arc mCE is 5x + 10)

Step-by-step explanation:

When we have two chords crossing in a circle, there is a property where the angle in the cross point is equal half the sum of the corresponding arcs.

So in this case, we have:

70° = (mCE + mDF)/2

Assuming mCE is 5x + 10, we have:

70 = (5x + 10 + 11x + 2)/2

70 = (16x + 12)/2

70 = 8x + 6

8x = 64

x = 8

So the arc mDF is:

mDF = 11x + 2 = 11 * 8 + 2 = 90°

The measure of arc DF should be 90 degrees.

Here we assume arc mCE should be 5x + 10

Since mDF = 90°

Also we know that at the time when two chords should be crossing in a circle so the angle in the cross point should be equivalent to the half the sum of the arcs

So base don this.

\(70 = (mCE + mDF)\div 2\\\\70 = (5x + 10 + 11x + 2)\div 2\\\\70 = (16x + 12)\div 2\)

70 = 8x + 6

8x = 64

x = 8

Now the arc mDF is:

mDF = 11x + 2

= 11  (8) + 2

= 90°

Hence, The measure of arc DF should be 90 degrees.
