Q5a) 3 = 2x -7

10 = 2x
x = 5. True

b) 3 < 2x -9

12 < 2x
6 < x False

c) 2 <_ x + 6

-4 <_ x True (because -4, -3, -2 ... Infinity can be values of x)

d) 18 = 6x - 12

30 = 6x
x = 5. True

e) 3 = 2 + x

x = 1. False


Q6)

7 < 5x - 16
23 < 5x
4.6 < x

4 is not a solution of this inequality (i couldnt put equal sign under the inequality but lets assume we did and 4 is still not a solution)

Q7)

9x < 63
x < 7

They dont because x is less than 7 not less than equal to 7 so this inequality is not true for this particular set

<em>5.</em> Input 5 where the x's, 3 = 2(5) - 7 is a true statement. 10 - 7 = 3
3 < 10 - 9 is a false statement, 3 > 1 is a true statement
2 is less than or equal to 11, is a false statement (2 is less than 11, but not equal to)
18 = 30 -12 is a true statement  30 - 12 = 18, 18=18
3= 2 + 5 is a false statement, 3 is not equal to 7

<em>6. </em>7 is less than or equal to 5(4) -16, 20 - 16 = 4, 7 is not less than or equal to 4. Therefore, 4 is not a solution.

<em>7. </em>9(5) - 3 < 60, 45-3 < 60, 42 < 60, 42 is less than 60, so the equation is true. 
9(6) - 3 < 60, 54 - 3 <  60, 51 < 60, 51 is less than 60, so the equation is true.
6(7) - 3 < 60, 63 -3 < 60,  60 < 60, 60 is equal to 60, the equation is false.

60 G of Henry's favorite breakfast cereal is 1/4 sugar how much sugar is in a 60g serving converted
katrin2010 [14]

Answer:

Step-by-step explanation:

Fraction of sugar in 60 gram cereal = 1/4

1/4 parts means that if 60 gram sugar is divided into four parts then out of that one part is sugar.

Amount of sugar in cereal in grams = 1/4 of 60 gram

Amount of sugar in cereal in grams = 1/4 * 60 gram = 15 grams.

Therefore, 15 grams sugar is in a 60 gram serving converted.

The perimeter of this triangle is 25 units. An angle bisector divides one side of the triangle into lengths of 2 and 3. Find the
grin007 [14]

Answer:

   8 and 12

Step-by-step explanation:

Sides on one side of the angle bisector are proportional to those on the other side. In the attached figure, that means

  AC/AB = CD/BD = 2/3

The perimeter is the sum of the side lengths, so is ...

  25 = AB + BC + AC

  25 = AB + 5 + (2/3)AB . . . . . . substituting AC = 2/3·AB. BC = 2+3 = 5.

  20 = 5/3·AB

  12 = AB

  AC = 2/3·12 = 8

_____

<em>Alternate solution</em>

The sum of ratio units is 2+3 = 5, so each one must stand for 25/5 = 5 units of length.

That is, the total of lengths on one side of the angle bisector (AC+CD) is 2·5 = 10 units, and the total of lengths on the other side (AB+BD) is 3·5 = 15 units. Since 2 of the 10 units are in the segment being divided (CD), the other 8 must be in that side of the triangle (AC).

Likewise, 3 of the 15 units are in the segment being divided (BD), so the other 12 units are in that side of the triangle (AB).

The remaining sides of the triangle are AB=12 and AC=8.
