Answer:
w =
Step-by-step explanation:
We have t = 4w, the question is asking to rearrange the equation to make "w" the subject, meaning that we have to isolate the variable w.
When we have a number (usually known as a coefficient) next to a variable and want to get rid of it, we need to divide it by both sides. Therefore :
t = 4w

Since "t" is an undefined variable and has no initial value, you cannot divide it by anything, therefore it'll stay as [t/4 = w]
Answer:
Suzanne is incorrect.
Step-by-step explanation:
To figure out if the two equations are equivalent, we can simplify each one of them.
Simplifying the first equation, we get:
Simplifying the second equation, we get:
Now that both equations are simplified, we can see that the equations are not equivalent. Suzanne is incorrect.
We are given dimensions of model and actual figure.
model: 9.5cm actual : 30.5m.
We need to find the length of actual shape for the scale factor 5cm.
Let us assume actual length be x m.
Let us set a proportion now.
<h3>5 : x = 9.5 : 30.5</h3>Let us convert proportion into fractions.
On cross multiplying, we get
9.5x = 5× 30.5
9.5x = 152.5.
On dividing both sides by 9.5, we get
x=16.05.
<h3>Therefore, the scale factor for a model is 5cm= 16.05 m.</h3>
