The x is going to be a negative number to get the 3. so start off minus 5 from plus 5 and minus five from the other side too. the positive 5 and the negative cancel out and then take it fromt here with three and the negative 5.

Well you would want to find x so you want to be itself
first subtract 5 on both sides to get x by itself and whatever you do to one side you have to do to the other
X +5=3
-5.-5
x= -2 < that's your answer

Answer:

x = 323 in

Step-by-step explanation:

Given triangles are similar, so their corresponding sides would be in proportion:

3ft = 3*12 = 36 in

5ft 8 in = 5*12 + 8 = 68 in

14 ft 3 in = 14*12 + 3 = 171 in

$\frac{3 \: ft}{14 \: ft \: 3 \: in} = \frac{5 \: ft \: 8 \: in}{x} \\ \\ \frac{36}{171} = \frac{68}{x} \\ \\ x = \frac{171 \times 68}{36} \\ \\ x = \frac{11628}{36} \\ \\ x = 323 \: in \: \\ \\ x = 26 ft \: 11 in$

Answer:

$b = 0.0138$

Step-by-step explanation:

Given

Regression Equation:

$DD=2.69+0.0138D$

Required

Determine the slope of the regression line

The equation of regression is of the form

$Y = a + bX$

Where b represents the slope;

Compare $Y = a + bX$ to the given equation

$DD=2.69+0.0138D$

We have that:

$Y = DD$

$a = 2.69$

$b = 0.0138$

$X = D$

Hence; the slope is:

$b = 0.0138$

The length of a concrete slab is three more than three times the width. It's area is 330 square feet. What is the length of the

marin [14]

Answer:

Width: 10.5 feet

Length: 31.5 feet

Step-by-step explanation:

Let x represent width of the concrete slab.

We have been given that the length of a concrete slab is three more than three times the width. So length of the slab would be $3x$ .

We are also told that the area of slab is 330 square feet. We can represent this information in an equation as:

$x\cdot 3x=330$

$3x^2=330$

$x^2=\frac{330}{3}$

$x^2=110$

Now, we will take square root of both sides.

$\sqrt{x^2}=\sqrt{110}$

$x=10.488\approx 10.5$

Therefore, the width of slab is approximately 10.5 feet.

The length of the slab would be $3x\Rightarrow3(10.5)=31.5$ .

Therefore, the length of slab is approximately 31.5 feet.
