Basically if you have an exponent at the end of a 10, 10^{7} , then in the end the extended notation is going to have 7 zeros. So it'll be 10000000. Then you multiply whats in the rest of the equation together. There's the beginning :) I hope it helps.

Can anyone help me please? <br> What is<br> 21 times x = 7
n200080 [17]

Answer:

x = 1/3

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other:

21x = 7

Divide 21 from both sides:

(21x)/21 = (7)/21

x = 7/21

x = 1/3

x = 1/3 is your answer.

Given the following formula, solve for a.
Elena L [17]

Answer:

A. a = 2s - b -c

Step-by-step explanation:

Rearrange the equation in a way that you have only a on one side. When solving equations you can add, subtract, multiply or divide by the same number/variable/expression on the both sides.

s = \frac{a + b + c}{2}

Multiply by 2 to get rid of the fraction.

s \cdot 2 = \frac{a + b + c}{2} \cdot 2

On the right side the 2 cancels out:

s \cdot 2 = a + b + c

On the right side next to a are still b and c. But we want a alone. Subtract b.

s \cdot 2 - b = a + b + c - b

b - b on right side gives 0.

s \cdot 2 - b = a + c + 0

The step above is usually skipped, because number + 0 = number.

s \cdot 2 - b = a + c

Next to a there is still c. Subtract c.

s \cdot 2 - b - c = a + c - c

c - c on the left is 0.

s \cdot 2 - b - c = a

So our answer is:

s \cdot 2 - b - c = a

It can be rewritten to (change sides):

a = s \cdot 2 - b - c

And s · 2 can be rewritten to 2s:

a =  2s - b - c
