2/8 ÷ 2
1/4
2/8 in simplest form is = 1/4
and
5/8 in simplest form
5/8
5/8 = 0.625 as a decimal form
5/8 = 0.63 in 2 decimal places
5/8 = 0.6 to the nearest tenth
5/8 = 0.63 to the nearest hundredth
5/8 = 0.625 to the nearest thousandth
X + y = 8
Replace y as y = y Insert x back into the original
x + x - 2 = 8 5 + y = 8
2x - 2 = 8 - 5 - 5
+ 2 + 2 y = 3
2x = 10 (5, 3)

2 2
x = 5
Answer: C
C because x=1 pound and y=$2.50 in point W
Showing unit rate
Hope this helped :)
I think is <span> x = 7 or<span> x = -7
</span></span><span>Equation at the end of step 1 :</span><span> 3x2 - 147 = 0
</span><span>Step 2 :</span><span>Step 3 :</span>Pulling out like terms :
<span> 3.1 </span> Pull out like factors :
<span> 3x2 - 147</span> = <span> 3 • (x2 - 49)</span>
Trying to factor as a Difference of Squares :
<span> 3.2 </span> Factoring: <span> x2 - 49</span>
Theory : A difference of two perfect squares, <span> A2 - B2 </span>can be factored into <span> (A+B) • (A-B)
</span>Proof :<span> (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 <span>- AB + AB </span>- B2 =
<span> A2 - B2</span>
</span>Note : <span> <span>AB = BA </span></span>is the commutative property of multiplication.
Note : <span> <span>- AB + AB </span></span>equals zero and is therefore eliminated from the expression.
Check : 49 is the square of 7
Check : <span> x2 </span>is the square of <span> x1 </span>
Factorization is : (x + 7) • (x - 7)
<span>Equation at the end of step 3 :</span><span> 3 • (x + 7) • (x - 7) = 0</span>
Answer:
the answer is conversion factor.
