The first one is A and the second one is D.
Answer:
? = 1
Step-by-step explanation:
3/8r - 1/4r + 2s
= 3/8r - 2/8r + 2s
= 1/8r + 2s
Assume the number we are looking for in n
we want to know the value of n that makes 1/7 divided by n is 14
Transforming this to an equation:
(1/7) / n = 14
this means that:
1/7 = 14n
1 = 7 x 14n
1 = 98n
n = 1/98
Therefore:
1/7 divided by 1/98 will give us 14
Answer:
Step-by-step explanation:
To solve this problem, we just need to transform from ordinary language to algrabraic language.
"Lola says: Argos, my dog, has 10 kilograms less than Roco"
This statement can be expressed as: , which means we must subtract 10 kilograms from Roco's weight.
Therefore, Argos' weight is given by the expression
