Answer:

The answer x=13 or x=1

Step-by-step explanation:

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

|x−7|=6

Solve Absolute Value.

|x−7|=6

We know eitherx−7=6orx−7=−6

x−7=6(Possibility 1)

x−7+7=6+7(Add 7 to both sides)

x=13

x−7=−6(Possibility 2)

x−7+7=−6+7(Add 7 to both sides)

x=1

Answer:

x=13 or x=1

Sammy is trying to determine how many triangles she can create out of a square grid that has a side of 14 inches. Use the image

saw5 [17]

Hello!

You first have to find the area of the square grid

To find this you multiply the sides

14 * 14 = 196

Next you have to find the area of the triangle

To find the area of a triangle you use the equation

$\frac{hb}{2}$

h is height
b is base

Put in the values you know
$\frac{7 * 14}{2}$

Multiply

$\frac{98}{2} = 49$

The area of the triangle is 49 inches squared

You divide the area of the triangle by the area of the square

196 / 49 = 4

The answer is 4 triangles

Hope this helps!

Sophie [7]

Answer:

Not similar

Step-by-step explanation:

They are not similar because the ratio is not the same. 42/35 = 1.2 and 14/10=1.4

A student in the Construction Trades program at the Cecil County School of Technology has 4 1/2gallons of paint. If he uses 2.75

Andrew [12]

Answer:

1.75 gallons of paint

Step-by-step explanation:

A student in the construction trades program has 4 1/2 gallons of paint

If the student uses 2.75 gallons in one room then the gallons of paint that are left can be calculated as follows

= 4 1/2 - 2.75

= 9/2 - 2.75

= 4.5 - 2.75

= 1.75

Hence 1.75 gallons of paint are left

A rectangle has a height to width ratio of 3:4.5. Give two examples of dimensions for rectangles that could be scaled versions o

OlgaM077 [116]

We have been given that a rectangle has a height to width ratio of 3:4.5.

Let h be height and w be width of rectangle.

We can set our given information in an equation as:

$\frac{h}{w} =\frac{3}{4.5}$

$h=\frac{3}{4.5} *w$

Now we will substitute h=1 in this equation.

$1=\frac{3}{4.5} *w$

$3w=4.5$

$w=\frac{4.5}{3} =1.5$

We can see that width of rectangle is 1.5 times height of rectangle.

Our one set of dimensions of rectangle will be: height=1 and width=1.5.

We can get many set of dimensions for our rectangle by multiplying both height and width of rectangle by same number.

Multiplying by 5 we will get our dimensions as: height 5 and width 7.5.

Therefore, (1 and 1.5) and (5 and 7.5) dimensions for rectangle will be scaled version of our rectangle.
