For the first question you shade in the bar to the 20% mark as she has saved 20% of the money needed for her jacket. To complete the bar you add the amount of how much each percentage is in dollars. We know 20%=$15 and the percentage goes up 20% each time so you keep adding $15 on. For question 2 the bar is half way between 0 and 20 and half of 20 is 10. As 10 is half of 20 we half 15 to get $7.50

Miles incorrectly gave the product of 7 * 2.6 as 14 * 42 to use a place value chart or an area model to help miles understand hi
mrs_skeptik [129]
It looks like he used the distributive property. He multiplied 7*2. Then. 7*6. Then he multiplied them together. That is not how you multiply numbers

Simplify the expression.<br> -5+i /2i
Andrei [34K]

Answer:

\frac{1+5i}{2}

Step-by-step explanation:

We know i×i=i^2 which has value of -1.

We will multiply numerator and denominator by i so the denominator will no longer contain imaginary part(s).

Also multiplying by i/i does not change the value of the fraction because i/i=1.

Numerator × i gives (-5+i)i=-5i+i^2=-5i-1

=-1-5i.

Denominator × i gives (2i)i=2i^2=-2.

So the simplified version of this fraction given is:

\frac{-1-5i}{-2}=\frac{1+5i}{2}

The last simplification come from me multiplying fraction by -1/-1.
