If 3d – (9 – 2d) = 51, find the value of 3d.
Vanyuwa [196]
First you open up the brackets so the sign for 2d changes to positive. So it will look like 3d-9+2d=51 then u simply the 3d-9+2d that should give 5d-9=51. Then you add 9 to both sides of the expression 5d-9+9=51+9. That will be 5d =60 so you divide 5 on both sides to find the value of 1 d which is 60/5=12 then to find 3d you multiply the value of d by three so it's 12(3)=36

Answer:

1. \frac{7^8}{7^6}=49

2. 7

3. 18

Step-by-step explanation:

Question 1:

Given:

The expression to simplify is \frac{7^8}{7^6}.

We use the property of exponent \frac{a^m}{a^n}=a^{m-n}

Therefore, \frac{7^8}{7^6}=7^{8-6}=7^2=7\times 7 = 49

Question 2:

Given:

The expression to simplify is 7(\frac{1}{2}+\frac{1}{2}).

We add the fractions first inside the parenthesis.

So, \frac{1}{2}+\frac{1}{2}=\frac{1+1}{2}=\frac{2}{2}=1

Now, 7(1)=7

Question 3:

The first five prime numbers are 1, 2, 3, 5, and 7.

Therefore, the sum of these five numbers is given as:

1+2+3+5+7=18
