Answer:
the largest possible value of x is 21
Step-by-step explanation:
39/x =3
3x =39
x=39/3
x= 13
51/x =3
3x =51
x= 51/3
x= 17
63/x =3
3x= 63
x= 63/3
x= 21
15% = $30
1% = 30 ÷ 15
1% = $2
100% = 2 x 100
100% = $200
Answer: The original price of the computer is $200.
Answer:
- equation: w +(2w -3) = 18/2
- length = 5 cm
- width = 4 cm
Step-by-step explanation:
Let w represent the width in cm. Then the length is 2w-3, 3 cm less than twice the width. The perimeter is twice the sum of these, so the sum of length and width is half the perimeter:
w + (2w -3) = 18/2
3w -3 = 9 . . . . collect terms
3w = 12 . . . . add 3
w = 4 . . . . divide by 3
2w-3 = 2·4 -3 = 5 . . . . length
The equation is w + (2w -3) = 18/2; the length is 5; the width is 4.
Add 5/7 on both sides.
It'll cancel out the negative 5/7, and it will make the x variable only equal to one number (Well, a mixed number.)
