<u>Answer:</u>
Seiji’s earning = $250;
Gavin’s earning = $275
<u>Explanation:</u>
Consider Seiji’s earning to be $x
According to question, Gavin earned $25 more than Seiji
Then, Gavin’s earning = x + $25
According to question, total earning is $525
Then, x + x + 25 = 525
Solving for x,
2x + 25 = 525
2x = 500
x = 250
Therefore, Seiji’s earning, x = $ 250
Gavin’s earning = 250+25 = $275
Given:
15 is decreased by three times a number, the result is 21.
To find:
The equation for the given statement and solve it.
Solution:
Let n be the unknown number. Then,
Three times of a number =
15 is decreased by three times a number =
It is given given that the result after subtraction is 21. So,
Divide both sides by -3.
Therefore, the required equation is and its solution is . Hence, the correct option is (a).
Answer:
y= 3x + 3
Step-by-step explanation:
From the graph we get 2 points: (-1,0) and (0,3)
(0,3) tells us that b = 3
and we use the equation to calculate m
m = = 3/1 = 3
so plugging m and b into y = mx + b gives us
y = 3x + 3
Piece(1)=36+9= 45 in
45 in > 44 in
so, piece(1)>piece(2)
