3r = 10 + 5s
Put the value of r = 10 to the equation and solve it for s:
3(10) = 10 + 5s
30 = 10 + 5s <em>subtract 10 from both sides</em>
20 = 5s <em>divide both sides by 5</em>
4 = s → s = 4
<h3>Answer: for r = 10, s = 4.</h3>
Answer:
Step-by-step explanation:
by definition, exponential equation represents exponential decay when the base is between 0 and 1. so if the base is a positive number greater than 1, it does not represent an exponential decay. the ans is D
Answer:
B
Step-by-step explanation:
The line is running only across coordinate points with an x coord of 2
Answer:
x>4
Step-by-step explanation:
Step 1: Subtract 9 from both sides.
x+9−9>13−9
x>4
Answer:
<h2>x = 8m</h2>
Step-by-step explanation:
Let the two triangles be represented as A and B.
Given two triangles with sides 12m 20m 16m and 6m 10m x.
Lengths of sides of triangle A = 12m, 20m, 16m
Lengths of sides of triangle B = 6m, 10m, x
It can be seen that each length of triangle A are twice that of B i.e triangle B dilated by a factor of 1/2.
A = 2B
<u>Considering the 16m length in triangle A and comparing it with the 'x'm length in triangle B, we can get the unknown length x as shown;</u>
16 = 2x
x = 16/2
x = 8m
