The answer is D.) 8
Explanation: 10p+5= 18p–6/2
Subtraction Property of equality states that you subtract the same number from both sides of an equation.
Subtract 10p from both sides of an equation
10p+5-10p = 18p-62-10p
Simplify:
5 = 8p -62
Addition Property of equality states that you add the same number from both sides of an equation.
Add 62 to both sides of an equation:
5+62 = 8p -62 +62
Simplify:
67 = 8p
Division Property of equality states that you divide the same number from both sides of an equation.
Divide by 8 in equation [3] ;
Simplify;
p = 8.375 ≈ 8 (approx)
Therefore, the value of p is, 8
Hope this helps :) sorry if wrong and sorry about confusion.
Answer:
<h2>8/9</h2>
Step-by-step explanation:
9 in total 4 blue
4/9 x 2
8/9
Answer:
15
Step-by-step explanation:
One way of doing it is by using the properties of summing things, like factoring out the minus sign:
<span><span>∑<span>n=2</span>8</span><span>−(n−5)</span>=−<span>∑<span>n=2</span>8</span><span>(n−5)
</span></span>
and splitting it up into two parts and again factor
<span>=−<span>(<span><span>∑<span>n=2</span>8</span><span>n−5<span>∑<span>n=2</span>8</span>1</span></span>)
</span></span>
The last sum is just counting how many numbers there are from 2 to 8, which is 7 (you can do it on your fingers). The first one can be calculated fast if we are clever and use this identity:
<span><span>∑<span>n=1</span>m</span>n=<span><span>m(m+1)</span>2
</span></span>
So what we get is
<span><span>=−<span>(<span>−1+<span><span>8(8+1)</span>2</span>−7</span>)</span>=8−72/2=8−36=−28.</span></span>
