Answer:
475
Step-by-step explanation:
Let's call the dryer price is x
Then, the price for the washer is 53 more than the dryer, it would be: x+53
Total price of washer and dryer = 1003
We get the equation:
x+(x+53) = 1003
2x + 53 = 1003
2x + 53 - 53 = 1003 - 53
2x = 950
x = 475
The dryer price is 475
Extra: you can find the cost of the washer by using x+53 = 475+53 = 528
Answer:
Total number of notes is 11.
Step-by-step explanation:
Value is 100 rupees…
5x + 20y = 100 and x + y = 11 are the two equations.
We can simplify…
5x + 20 y - 5x - 5y = 100 - 55 = 45
15y = 45 so y = 3
x = 11 - y = 8
So, we have 8 notes of 5 rupees denomination and 3 notes of 20 rupees denomination.
I hope it helps you.
Answer:
y =-2x+8
Step-by-step explanation:
We have a point and a slope
(5,-2) and m =-2
The slope intercept form of a line is
y = mx+b
y = -2x+b
Substitute in the point
-2 = -2(5)+b
-2 = -10+b
Add 10 to each side
-2+ 10 = -10+10 +b
8 = b
The equation is
y =-2x+8
11. 375x0.1425 = 53.475 (53.44 to 2 d.p.)
12. 116 / (9+7) = $7.25
Total payment / Hours spent working = Money per hour
