Answer:
x=2
ab=7
bc=5
Step-by-step explanation:
because you do
2x+3 = 4x+3
-3 -3
2x=4x
-2x -2x
x = 2
2x2+3
4+3
=7
4x2-3
8-3
=5
Answer:
750 profit
Step-by-step explanation:
Given :
Profit of 10 on white cement
Loss of 5 on Grey cement
Number of white cement sold = 325 bags
Number of Grey cement sold = 500 bags
Total profit made on sale of white cement :
10 * 325 = 3250
Loss made on sale of Grey cement :
5 * 500 = 2500
Total profit or loss :
3250 - 2500
= 750
Profit value is greater than. Loss value (hence, total profit of 750 was made).

Answer:
7 m
Step-by-step explanation:
Circumference of a circle uses the formula;
Circumference = 2 × pi × radius(r)
If the circumference = 44
then we use the formula above to calculate the value of the radius,
44 = 2 × pi × r...then divide both sides by (2 × pi(3.14))
Radius = 44 ÷ ( 3.14 × 2)
;Radius = 7.01
;Radius = 7m
The rule is adding 5 if we say n is 2 then nth term is
n + 5(or so I hope )
