Kenya is solving the equation 5 3/4 - 1/6x = 4 1/2. She gets to 1 1/4 = 1/6x. Is this a valid way to solve the equation? answer
Alona [7]

Answer:

15/2

Step-by-step explanation:

5 3/4 - 1/6x = 4 1/2

move the variable to it's own side.

5 3/4 - 4 1/2 = 1/6x

change the subtracting side to have common denominators

5 3/4 - 4 2/4 = 1/6x

1 1/4 = 1/6 x

divide both sides by 1/6, same thing as multiplying both sides by 6 (reciprocal)

30/4 = x

reduce: 15/2 = x

78 is 15% of what #?
nirvana33 [79]
1. 78 = 0.15x
    78 / 0.15 = x
    520 = x.....so 78 is 15% of 520

2. | 3x - 2 | = 8                               | x + 1 | = 1

3x - 2 = 8      -(3x - 2) = 8            x + 1 = 1          -(x + 1) = 1
3x = 8 + 2      -3x + 2 = 8             x = 1 - 1           -x - 1 = 1
3x = 10           -3x = 6                  x = 0                 -x = 2
x = 10/3           x = -2                                             x = -2

ur answer is : x = -2

3. 3y - 4x + 5 = 0
    3y = 4x - 5
      y = 4/3x - 5/3

What is the length of the side a ?<br><br> A=
vodka [1.7K]

Answer:

a = 5

Step-by-step explanation:

Notice that \triangle CDB is a right triangle where its hypotenuse is \overline{CB}. We can also see that a = CB. For this we must use the Pythagorean Theorem.

Recall:

The Pythagorean Theorem states that if you have a right triangle, the principal square root of the sum of the squares of each leg is the length the hypotenuse.

We can see that CD = 3 and DB = 4

a = \sqrt{CD^2 +DB^2} \\ a = \sqrt{3^2 +4^2} \\ a = \sqrt{9 +16} \\ a = \sqrt{25} \\ a = 5
