What is the solution to the equation represented by the model below?
Verizon [17]

Left side:

x+x+x+1+1+1+1+1+1+1+1 = 3x + 8


Right side:

x+x+x+x++1+1+1+1+1+1


Left side = Right side to solve x


3x + 8 = 4x + 6

Subtract 4x from both sides

3x + 8 - 4x = 4x + 6 - 4x

Simplify

-x + 8 = 6

Subtract 8 from both sides

-x + 8 - 8 = 6 - 8

Simplify

-x = -2

Multiply both sides by (-1)

-x * (-1) = -2 * (-1)

Simplify

x = 2


Answer

C. x = 2

Points B, D, and F are midpoints if the sides of ACE. EC=38 and DF=16. Find AC
vekshin1

Answer:

AC=32 units.

Step by step explanation:

Given information: B, D, and F are midpoints if the sides of ΔACE, EC = 38 and DF = 16.

Consider the below figure attached with this question.

According to the midpoint theorem, if a line segments connecting two midpoints then the line is parallel to the third side and it's length is half of the third side.

Since F and D are midpoints of AE and EC respectively.

Using midpoint theorem, the length of AC is twice of DF.

AC=2\times DF

Substitute the given values in the above equation.

AC=2\times 16

AC=32

Therefore, the length of AC is 32 units.

For the given decimal −0.009, find the two integers closest to it.
asambeis [7]

Answer:

The two integers closest to -0.009 are -1 and 0

Step-by-step explanation:

we have the number

-0.009

Convert to fraction number

-0.009=-\frac{9}{1,000}

In a number line

-\frac{1,000}{1,000} < -\frac{9}{1,000}

Remember that

-\frac{1,000}{1,000}=-1\\\frac{0}{1,000}=0

so

-1 < -\frac{9}{1,000}

therefore

The two integers closest to -0.009 are -1 and 0
