  Okay so first we need to find 40% of 7.50. To do this you simply divide the percentage by 100, so you have .4 now. You multiply 7.50 by .4 and get 3. Lastly, you just subtract 3 from 7.50 and you get $4.50

Emma will pay $4.50 after the discount.

So, what you need to do is 7.50 x .40 which is 3...

now minus that from 7.50.

7.50 - 3 = 4.50

So with the stores discount she will actually pay $4.50 for $7.50 worth of candy.

Mark buys a used car for $12,000. The value of the car depreciates 10% per year from the time he bought the car.
timama [110]

Answer:

option D

Step-by-step explanation:

r = 10% = 0.10

v(t) = P (1 - r)^t\\\\V(t) = 12000(1 - 0.10)^t\\\\V(t) = 12000\times (0.9)^t

The production of what number and 7 is less than 49
MArishka [77]
Many numbers, when multiplied by 7, are less than 49.  We can find an inequality for numbers x that are sufficient.

Clearly, 7x < 49 is the desired inequality.  We divide by 7 to find that x < 7 determines working numbers.

Solve 5c + 4 = -26
mr_godi [17]
<em>1) 5 c + 4 = - 26
5 c = -26 -4
5 c = -30
c = -30 / 5
c = -6    so correct option is B..

2) 3 x - x +2 = 12
2 x +2 = 12
2x = 12-2
2x = 10
x = 10/2
x= 5    so correct option is D

3 ) 3 ( x + 1 )+ 6 = 33
3x + 3 + 6 = 33
3x + 9 = 33
3x = 33-9
3x = 24
x = 24/3
x = 8   so correct option is B

4) y/-6=9
y=9 x -6
y= - 54   there is no such option i guess question is missing

5)(x +  4) /2 = 7
x +4 = 7 x 2
x + 4 = 14
x = 14-4
x = 10  so correct option is D

6)1/3 ( 2x - 8) = 4
2x/ 3 - 8 /3 = 4
2x - 8 / 3 = 4
2x - 8 = 4 x 3
2x - 8 = 12
2x = 12 + 8
2x = 20
x = 20/2
x = 10   so correct option is C
