Answer:
<em>90 calories in total</em>
Step-by-step explanation:
<em>We can solve this equation through the following steps:</em>
<em>Step One: Since we are told that a banana is 20 less calories than an orange, we can create the Let Statements:</em>
<em>Let x= the calories in a banana</em>
<em>Let x-20=the calories in an orange</em>
<em>Step Two: Create an equation</em>
<em>Since we are told "7 bananas have the same calories as 9 oranges" we translate"</em>
<em>7x=9(x-20) Distribute</em>
<em>7x=9x-180 Subtract 9x from both sides of the equation</em>
<em>7x-9x=-180 Simplify</em>
<em>-2x=180 Divide both sides by -2</em>
<em>x=90</em>
<em>∴There are 90 calories in a banana. </em>

Answer:
1156
Step-by-step explanation:
First you get the answer you divide by 9 since it is the denominator and ultimately means how many "pieces" or parts the whole number or amount will be in. You divide by 9 and get 289. Now you have the 1/9 part of 2601. You now multiply this number by 4 to get the 4/9 of 2601. Whennyou multiply by four you get 1156. I hope this makes sense and that it helps you.
