Answer:
Step-by-step explanation:
y = -3x + 9 ⇌ 3x = 9 - y ⇌ x = -y/3 + 9/3 ⇌ x = -y/3 + 3
Answer:
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z ----> the scale factor
x ---> the volume of the model of a swimming pool
y ---> the volume of the actual swimming pool
so
we have
substitute
solve for x
Answer:
121 minutes
Step-by-step explanation:
<em>First, we divide the time by the miles</em>
22 ÷ 2 = 11
<em>So now that we have the unit rate, 1 mile for every 11 minutes, we can multiply 11 (the unit rate minutes) by 11 (the given miles she wants to reach)</em>
11 x 11 = 121
<em>So, in 121 minutes, Wendy can walk 11 miles. </em>
<em>(the double number line will look something like this, but going all the way until 121:11)</em>
