Answer:
let the number be y
4(y-7)=48
y-7=48/4
y-7=12
y=12+7=19

Answer:
![xy=wz](https://tex.z-dn.net/?f=xy%3Dwz)
Step-by-step explanation:
Given that:
Speed of Wilmer up the hill =
km/min
Time taken up the hill =
minutes
Speed of Wilmer down the hill =
km/min
Time taken up the hill =
minutes
Distance can be calculated by multiplying the Speed with Time i.e.
The formula for distance is given as:
![Distance = Speed \times Time](https://tex.z-dn.net/?f=Distance%20%3D%20Speed%20%5Ctimes%20Time)
Distance up the hill = ![y\times x =xy\ kilometers](https://tex.z-dn.net/?f=y%5Ctimes%20x%20%3Dxy%5C%20kilometers)
Distance down the hill = ![z\times w =wz\ kilometers](https://tex.z-dn.net/?f=z%5Ctimes%20w%20%3Dwz%5C%20kilometers)
It is well known that, the distance up the hill and down the hill will be same.
Putting both the values equal, we get:
![xy=wz](https://tex.z-dn.net/?f=xy%3Dwz)
Answer:
<h2>6÷4(7+8) </h2><h2>= 22,5</h2>
<h2>8-6(4+9)</h2><h2>= 26</h2>
<h2>4÷8(9+3)</h2><h2>= 6</h2>
Step-by-step explanation:
<h2>6÷4(7+8)</h2><h3>= 6÷4(15)</h3><h3>= 1,5 × 15</h3><h3>= 22,5</h3>
<h2>8-6(4+9)</h2><h3>= 8-6(13)</h3><h3>= 2 × 13</h3><h3>= 26 </h3>
<h2>4÷8(9+3)</h2><h3>= 4÷8(12)</h3><h3>= 0,5 × 12</h3><h3>= 6</h3>
