Answer:
x + y = 4
Step-by-step explanation:
Given the 2 equations
3x + 4y = 10 → (1)
2x + 3y = 6 → (2)
Subtract (2) from (1) term by term on both sides
x + y = 4
So 1 would be 5r+20 and then the second one would be
Two angles are said to be supplementary if their sum is 180 degrees. So, if x and y are supplementary angles, the formula is

We know that one of the angles (say x) is 98. So, the equation updates to

If we want to solve for the other angle, we can simply subtract 98 from both sides to get

Answer:
32.1 pounds
Step-by-step explanation:
Given data
Percentage of body fat= 19.8%
Weight= 162pounds
Let us find 19.8% of the persons weight
=19.8/100*162
=0.198*162
=32.076
Therefore, 32.1 pounds of the weight is fat
