Slope = 1.429/2.000 = 0.714
x-intercept = 10/5 = 2
y-intercept = 10/-7 = -1.42857
Answer: 16875
Step-by-step explanation:
Let the price of the washing machine be x.
Since she loses 20% in the bargain, this implies that she sold it at (100% - 20%) = 80%.
Therefore, 80% of x = 13500
0.8 × x = 13500
0.8x = 13500
Divide both side by 0.8
0.8x/0.8 = 13500/0.8
x = 16875
Therefore, the price at which she bought the washing machine is 16875 rupees.
Answer:
76cm^2
Step-by-step explanation:
Can be divided in three parts
Part 1; Area= 6×2
=12cm^2
Part 2; Area= 2×2
=4cm^2
Part 3; Area= 10×6
=60cm^2
Add them; 60+4+12
76
(X+Y+Z)/3=84 X,Y,Z IS THE THREE UNKNOWN SCORES.TO KNOW THE TOTAL , MULTIPLY THE 84 BY 3.
84*3=252
(252+H)/4=87 H IS THE FOURTH GRADE HE SHOULD HE IF HE WANTS HIS AVERAGE TO BE 87
87*4=348
252+H=348
H=348-252
H=96
