Answer:
c) if x=2, then 4x=8
Step-by-step explanation:
10.71% is 9% of 84.
So 10.71% is the answer.
X + y = 19
10x + 4y = 100
This is a systems of equations.
Isolate x from the first equation:
x = 19 - y
Now, plug it into the second:
10(19 - y) + 4y = 100
190 - 10y + 4y = 100
-6y + 190 = 100
-6y = -90
y = 15
Plug y in and solve for x:
10x + 4(15) = 100
10x + 60 = 100
10x = 40
x = 4
There are four 10-point questions and fifteen 4-point questions.
Answer:

Step-by-step explanation:
Given:
Initial weight of the new born baby = 3,874 grams
final weight of the baby = 3,465 grams
Now,
the current percentage of the weight loss will be calculated as:
Weight loss percentage =
%
on substituting the respective values, we get
Weight loss percentage =
%
or
Weight loss percentage = 10.55%
