3x< 21 fill in the blank x < ____

1 answer:

7 0

To solve this problem, you need to have x alone on one side of the inequality. To do this, you need to undo the multiplication that is bonding 3 and x together. To undo this, you need to divide both sides by 3.

This results in the inequality x<7.

Your final answer is x<7.

Steffie makes a scale drawing for a crate with the demensions 15 inches long by 12 inches wide. Her scale factor is 1:3. Brian m

rodikova [14]

Answer:

Dimensions → (5 inches × 4 inches)

Step-by-step explanation:

Scale factor used for the drawing by Steffie = $\frac{1}{3}$

Since, scale factor = $\frac{\text{Dimension of the drawing}}{\text{Actual dimension}}$

For Steffie,

Actual length of the crate = $\frac{\text{Dimension of the drawing}}{\text{Scale factor}}$

= $\frac{15}{\frac{1}{3}}$

= 45 inches

Actual width of the crate = $\frac{12}{\frac{1}{3} }$

= 36 inches

Since Brian used the scale factor = $\frac{1}{9}$

Length of the drawing = Actual length × Scale factor

= 45 × $\frac{1}{9}$

= 5 inches

Width of the drawing = Actual width × Scale factor

= 36 × $\frac{1}{9}$

= 4 inches

Therefore, dimensions of the drawing made by Brian are (5 inches × 4 inches)

The length of a rectangle is 5 more than the side of a square, and the width of the rectangle is 5 less than the side of the squ

ANEK [815]

Answer:

Step-by-step explanation:

Given :

Length = l

Width = w

Area of square = 45

Let side of square = x

Area of square = x²

45 = x²

√45 = x

l of rectangle = x + 5 = √45 + 5

w of rectangle = x -5 = √45 -5

Area of rectangle= l * w

Area = (√45 + 5) * (√45 - 5)

Area = 45 - 5√45 + 5√45 -25

Area = 45 -25

Area of rectangle = 20
