Answer:

Step-by-step explanation:

1/4a + 1/3a + 8 = 22

Collect like terms

1/4a + 1/3a = 22 - 8

Simplify

3a+4a/12 = 14

7/12a = 14

Divide both sides by 7/12

a = 14 ÷ 7/12

= 14 × 12/7

= 168/7

= 24

a = 24

Check:

1/4a + 1/3a + 8 = 22

1/4(24) + 1/3(24) + 8 = 22

24/4 + 24/3 + 8 = 22

6 + 8 + 8 = 22

22 = 22

Simplify 63 ÷ 4 + 2 x 9(32 x 8 – 17 x 4).
kozerog [31]

<u>Answer:  </u>

After simplifying 63÷4+2 ×9(32 ×8-17 ×4 ) we get 3399.75

<u>Solution: </u>

We need to simplify 63÷4+2 ×9(32 ×8-17 ×4 ).

We will be using BODMAS rule to solve. According the BODMAS rule, Bracket has the highest precedence, than comes division, multiplication, addition and at last subtraction.

On solving bracket first, applying multiplication and then subtraction we get

=63÷4+2 ×9(256-68 )

=63÷4+18 ×188

Now doing division first we get

=\frac{63}{4}+18 \times 188

As multiplication have precedence over addition, we get

=\frac{63}{4}+3384

=\frac{63+13536}{4}=\frac{13599}{4}=3399.75

Hence after simplifying 63÷4+2 ×9(32 ×8-17 ×4 ) we get 3399.75
