Answers:

a*b = 1/2

a/b = 8/9

=============================================================

Explanation:

The horizontal bar over the 6 means the 6 goes on forever

So we have a = 0.66666... which converts to the fraction a = 2/3

The b = 0.75 converts to b = 3/4

-------------------

We can then say

a*b = (2/3)*(3/4)

a*b = (2*3)/(3*4)

a*b = 6/12

a*b = 1/2

and

a/b = (2/3) divide by (3/4)

a/b = (2/3)*(4/3)

a/b = (2*4)/(3*3)

a/b = 8/9

Note how I flipped the second fraction when I changed from a division to a multiplication.

Please help ASAP!! I'm in. a google meet rn and need to prove I got this question right
Aleks04 [339]

Answer:

x = 5.4

Step-by-step explanation:

(This question has already been answered, but both of the incorrect ones were deleted, so for future reference...)

Fig A is a scale image of Fig D. These two quadrilaterals are similar, and thus, the side lengths of corresponding sides are proportional. Set the proportion x/3 = 7.2/4 (you could alternatively write it as x/7.2 = 3/4 but for the simplicity's sake, and assuming anyone who has this problem would already know how to solve proportions like these...)

7.2/4 = 1.8

so

x/3 = 1.8

now multiply both sides by 3 to get x = 5.4

  • Division Property of Equality
  • Addition Property of Equality

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

5a - 10b = 45

<em>b</em> = 3

<u>Step 2: Solve for </u><em><u>a</u></em>

  1. Substitute in <em>b</em> [Equation]:                                                                                5a - 10(3) = 45
  2. Multiply:                                                                                                             5a - 30 = 45
  3. [Addition Property of Equality] Add 30 on both sides:                                  5a = 75
  4. [Division Property of Equality] Divide 5 on both sides:                                  a = 15

I need help on this question I don’t understand
mixas84 [53]

Answer:

x = 25

Step-by-step explanation:

Since these 2 angles are vertical angles, then they are both equal. Set up an equation and then solve it.

75 = 4x - 25

75 + 25 = 4x

100 = 4x

100/4 = 4x/4

25 = x

Hope this helps. Brainly will be highly appreciated.
