Answer:
y = 50
Step-by-step explanation:
Firstly, let's make an equation. We know that when y is 15, x is 3. Or, in other words, y is 5 times what x is. Therefore we can use the equation, y = 5x.
Now, just plug x into the equation.
y = 5(10)
y = 50
Answer:
<h2><em><u>61 marks</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>,</u></em>
Marks of the four exams = 65, 80, 76, 68
Let the mark for the fifth exam be = x
Mean of the five exams = 70
<em><u>Therefore</u></em><em><u>,</u></em>
<em>By</em><em> </em><em>the</em><em> </em><em>problem</em><em>, </em>
=> 289 + x = 70 × 5
=> 289 + x = 350
=> x = 350 - 289
=> x = 61
<em><u>Hence</u></em><em><u>,</u></em>
<em><u>Marks</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>fifth</u></em><em><u> </u></em><em><u>exam</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>61</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
I divided the two fractions & drew a model.
So we know that the bird seed will last 2.5 days.
Knowing this, we can go with:
B. Rectangle model divided into six equal sections, five sections are labeled five-sixths and two sections are labeled one-third, equaling two and one-half days.
Let me know if you find any problems with my answer.
The form for that type of equation is y=|x-h|+k
H is the horizontal movement, k is the vertical.
So for your equation, y=|x-(-7)|+0
Final answer:
Move to the left 7 and up 0.
Hope I helped :)
