Answer:
0.80A + 0.92B = 63 .....1
A + B = 75 ......2
Step-by-step explanation:
Let A and B represent the total possible score in part A and B respectively;
Analysing each sentence of the question;
Sam scored 80% on Part A of a math test and 92% on part B of the math test. His total mark on the test was 63
80% of A + 92% of B = 63
0.80A + 0.92B = 63 ......1
The total possible marks for the test was 75;
A + B = 75 .....2
So, equation 1 and 2 provides a set of simultaneous equations that can be used to represent and solve the situation.
Solving the simultaneous equations, we will arrive at;
Part A = 50
Part B = 25
Answer:
Step-by-step explanation:
First, change the mixed numbers into improper fractions:
5 2/3 = 17/3
Then, find the common denominator:
41/6 + 17/3=
LCM = 6
17/3 *2 = 34/6
41/6 + 34/6
Last, Add
25/6 or
12 1/2
Hope this helps!
mark brainliest if possible!
