Red and grey bricks were used to build a decorative wall. The number of red bricks and grey bricks was 5/2. There were 140 brick

ozzi

Answer:

100 red bricks

Step-by-step explanation:

Let's say red bricks is equal to 5x

Gray bricks is equal to 2x

We have an equation

2x + 5x = 140

= 7x = 140

Divide through by 7 to get the value of x

X = 140/7

X = 20

Red bricks = 5(x)

= 5(20)

= 100

Gray bricks = 2(x)

= 2(20)

= 40

Therefore in conclusion the number of red bricks is 100.

Digiron [165]

Answer:

$no \: solution$

Step-by-step explanation:

1) Expand

$6x - 36 - 5x + 35 = x + 6$

2) Simplify 6x - 36 - 5x + 35 to x - 1.

$x - 1 = x + 6$

3) Cancle x on both sides.

$- 1 = 6$

4) Since −1 = 6 is false, there is no solution.

No Solution

Hence, this equation have no solution.
