Answer:

The answer is  X = 0.67

Lemur [1.5K]2 years ago

Answer:

-2x = -3 [Simplified Version] | X = 0.67

Step-by-step explanation:

-4(2x - 4) = 2(2x - 1)

-8x + 16 = 4x - 2  [Distributive Property]

Subtract 16 on both sides

-8x = 4x - 18

Subtract 4x on both sides

-12x = -18

Divide by -12

X = 0.67

Can someone help me find the area of the following figure
ExtremeBDS [4]
1. The area of the full rectangle is 21 * 28 = 588. We will need this later. 

Like you drew, there is an imaginary triangle missing. We can find the dimensions of it by subtracting from the given information. The shorter leg of it is 21 - 12 = 9, the longer leg is 28 - 14 = 14.

Now we find the area of the triangle. Area of a triangle is 1/2 * base * height. So 1/2 * 9 * 14 = 1/2 * 126 = 63. 

Now we do the full area of 588 minus the area of the missing triangle piece. 

588 - 63 = 525 ft²

2. Do the area of the rectangle and then this time add on the area of the triangle. 7 * 15 = 105. Area of the triangle = 1/2 * 2 * 7 = 1/2 * 14 = 7. 

105 + 7 = 112 in²

5.1+2.3x=23.5..solve for x
erastovalidia [21]

Answer:

see beleow

Step-by-step explanation:

Let's solve your equation step-by-step.

5.1+2.3x=23.5

Step 1: Simplify both sides of the equation.

2.3x+5.1=23.5

Step 2: Subtract 5.1 from both sides.

2.3x+5.1−5.1=23.5−5.1

2.3x=18.4

Step 3: Divide both sides by 2.3.

2.3x

2.3

=

18.4

2.3

x=8
