B. is the answer hope I got it right: )
The distance, s = 40t₁ where t₁ is the time to complete the outward journey.
The same distance = vt₂ where t₂ is the time to complete the return journey at speed v.
For the whole journey, 2s=60(t₁+t₂). Therefore s=30(t₁+t₂)=40t₁=vt₂.
30t₁+30t₂=40t₁, 10t₁=30t₂, t₁=3t₂, so s=120t₂=vt₂ and v=120kph.
Convert to improper fraction: 2 5/12 = 29/12
Divide 29 by 12: 29/12 = 2.42
2.42 inches
Answer
55 for the top left and 35 for the top right
Explanation
7*7+6=49+6=55
And it is 7x+6
Top right
6x-7
6*7-7=42-7=35
The solving linear equation states that the temperature of the oven is 119 after an minute.
<h3>What is a linear equation?</h3>
A linear equation is just an algebraic equation of something like the form y=mx+b that only contains a constant and a first-order (linear) component, where m represents the slope and b is the y-intercept. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where y and x are now the variables.
<h3>According to the given data:</h3>
Given:
y = 40x+79
X = number of minutes using it to bare:
When X = 1
y = 40(1)+79
y = 119
It means that the temperature of the oven is 119 after an minute.
