An orange has 20 fewer calories
tatyana61 [14]

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>

Need help (zoom if necessary)
slamgirl [31]
The answer is 20n + 10 = 90 because the bar seats 10 people so you take 90-10 and you're left with 80. Four seats are at a table so you take 80/4 and you're left with 20. All you need to do now is reverse the order to fit the answer, and since you originally subtracted, you'd add. You could also do 20x4 + 10 and see that it equals 90 to check your answer.

Solve algebraically<br><br> 8x + 10y = -4<br><br> -4x = 2 + 5y
Rufina [12.5K]

The answer to the first one is:

x=-5/4y+-1/2. Why? 

 In the equation 8x+10y=-4, you subtract 10y form each side which leaves you with 8x=-10y-4. Right? Then you divide each side by 8 which gives you the answer

The answer to the second one is the same answer to the first problem. Why? Because you can already divide each side which gives you x=-5/4y+-1/2.

Hope this helps :^)
