The answer is 0.41 but what do you not understand? Hope I helped!
Answer:
Step-by-step explanation:
Note that 80% is 8 times 10%.
Thus, we could start with "If 10% of a number is 7" and multiply both quantities by 8: "80% of a number is 56."
Think:
10% of a number is 7,
20% is 14,
50% is 35,
70% is 49, and
80% is 56.
Answer:
y=1.7
Step-by-step explanation:
4y+18=14.7y
18=14.7y-4y
18=10.7y
18/10.7=10.7y/10.7
1.7=y
<h2>Linear equations</h2>
<em>The </em><em>graphical representation</em><em> of a linear equation is a straight line. To solve</em><em> linear equations</em><em>, i</em><em>t is important to keep in mind the following key concepts:</em>
- <em>Maintain the balance of the equation by applying the </em><em>same operations</em><em> to both sides of the equation.</em>
- <em>Clear the variable using like terms.</em>
- <em>Use </em><em>inverse operations</em><em> to rearrange the equation.</em>
<h3>-x + 5 = 1</h3>
We will subtract 5 from both sides.
<h3>−x + 5 - 5 = 1 - 5</h3><h3>−x = -4</h3>
<em>We divide both sides by -1.</em>
<h3>-x/x = -4/-1</h3><h3>x = 4</h3>
Answer: <em>Therefore the solution of the exercise </em><em>-x+5=1,</em><em> is </em><em>x = 4</em><em>. The </em><em>correct option</em><em> is </em><em>"D".</em> ✅

Given:
students going to the game = 56
students in each van = 7
number of vans used = unknown; x
The number sentence that can be used to find out how many vans are needed to take the students to the game is:
7 * x = 56
x = 56/7
x = 8 vans needed.
