Red and grey bricks were used to build a decorative wall. the number of red bricks/number of grey bricks was 5/2 there were 140 bricks used in all. how many red bricks were used?

5/2 = 5:2

Lets take 5:2 as 5x and 2x.

5x + 2x = 140

7x = 140

x = 140/7

x = 20

So, 5x = 5x20 = 100 red bricks

and, 2x = 2x20 = 40 grey bricks.

100 + 40 = 140 bricks

So, to build the decorative wall, 100 red bricks and 40 grey bricks were used.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
