Answer:
7.5 kg
Step-by-step explanation:
Ratio of sand to cement = 24kg : 5kg
Today he needs to make the same type of mortar mix, but he will use 36kg of sand.
Let
x = quantity of cement used
Ratio of sand to cement = 36 kg : x kg
Equate both ratios
24 kg : 5 kg = 36 kg : x kg
24/5 = 36/x
Cross product
24 * x = 5 * 36
24x = 180
x = 180/24
x = 7.5
x = quantity of cement used = 7.5 kg
Answer:
6x+3
Step-by-step explanation:
you add common terms which is x+5 and x is equal to 1 so its 5+1 which is 6 and the 3 you can't add anything to it so the answer will be 6x+3
(2 things/sec) x (3,600 sec/hour) = 7,200 things/hour
