Answer: The height of wall is 10.5 feet.

Step-by-step explanation:

Since we have given that

Number of bricks to build = 1470

Length of wall = 20 feet

We need to find the height of wall.

As we know that

Bricklayer's formula is given by

$N=7LH\\\\1470=7\times 20\times H\\\\1470=140\times H\\\\\dfrac{1470}{140}=H\\\\10.5\ ft=H$

Hence, the height of wall is 10.5 feet.

<u>Answer</u>

= 5 units

<u>Explanation</u>

2a - 2 = a + 1

2a - a = 1+2

a = 3

XY = 3a - 4

= 3×3 - 4

= 9 - 4

= 5 units

a triangle has sides with lengths of 5x, 15 and 17. the perimeter of the triangle is 45 meters. what is the value of x?

Artyom0805 [142]

The value of x
5x+15+17(sides)=45(perimeter of sides/sum of sides)
5x+32=45
5x=45-32
5x=13
x=13/5
x=2.6
The value of x is 2.6
