Answer:
25% should go
Step-by-step explanation:
If she wants to save $2,400;
Then in a month, she should save 2400/12 = 200
So now we need the amount of her monthly earnings will this savings be
That will be;
200/800 * 100%
= 1/4 * 100% = 25%
Answer:
not a factorable number i think
Step-by-step explanation:
1.80 per lb for 100 lbs = 1.80 * 100 = 180
1/10 * 180 = 180/10 = $ 18 <==
Answer:
y = -5x + 19
Step-by-step explanation:
Note that the equation of any line parallel to y= -5x+7 has the same form as y= -5x+7, but a different constant. Knowing that this new line passes thru (2,9), we determine the value of this constant as follows: 9 = -5(2) + C, or 9 = -10 + C. Then C = 19, and the equation of this new line is
y = -5x + 19
3x-y=2....(i)
2x-y=3.....(ii)
now adding the eqn I and ii ,
3x-y=2
2x-y=3
+ + +
5x=5
x=1
Now substituting the value of x in eqn I
3×1-y=2
3-y=2
-y=-1
y=1
