Step-by-step explanation:
Answer:
x = 13 1/2 or 27/2
Step-by-step explanation:
1st Add 2 to both sides: 2/3x-2+2=7+2
2nd Simplify: 2/3x = 9
3rd Multiply both sides by 3: 3*2/3x=9*3
4th Simplify: 2x=27
5th Divide both sides by 2: 2x÷2=27÷2
6th Simplify: x = 13 1/2 or 27/2
In this number 800 is 10 times
as much as what number.
To answer the query we can
illustrate this problem into a mathematical equation of
<span><span>
1.
</span>10 x N = 800</span>
<span><span>
2.
</span><span> 10N = 800</span></span>
<span><span>3.
</span><span> N = 800/10</span></span>
<span><span>
4.
</span><span> N = 80</span></span>
Hence, the number is 80.
Answer:
log9
Step-by-step explanation:
Using the rules of logarithms
logx + logy = log(xy)
logx - logy = log(
)
log
⇔ nlogx
Given
2(log18- log3) + 
log
= 2(log(
) ) + log
= 2log6 + log
= log6² + log
= log36 + log
= log( 36 × )
= log9
Question 1: 4/25 = 0.16
Question 2: 4 6/25 = 106/25 = 4 6/25 = 4.24
Question 3: 7.8 = 7 8/10 = 7 4/5
