Answer:
x=4
Step-by-step explanation:
4x-3=x+9
4x-x-3=9
4x-x=9+3
3x=9+3
3x=12
3/3
12/3=4
x=4
Answer:
Step-by-step explanation:
Let the numbers of steps you can take to reach your goal be x
Your goal is to take at least 10,800 steps per day and you have walked 7370 steps already.
x + 7370 >= 10800
x >= 10800 - 7370
x >= 3430
Answer: The both triangle are not scale version to each other.
Explanation:
It is given that the one rectangle measures 2 units by 7 units. a second rectangle measures 11 units by 37 units.
The two shapes are scaled version of each other if their corresponding sides are in same proportion. In other words the if two shapes scaled version of each then the shapes are similar.
The sides or first rectangle are 2 and 7. The measures of second rectangle are 11 and 37.
The proportion of small side is,

The proportion of large side is,

So,

Since the proportion are not equal, therefore both triangle are not scale version to each other.
Answer:
31.5 or 63/2
Step-by-step explanation:
to do this, first you need to transform the <u>mixed number</u> <em>(3 1/2)</em> into an <u>improper fraction</u>, to get 7/2.
then you just multiply 9 by 7/2
9/1 (7/2)
63/2 = 31.5
<em>both of the answers in bold are correct</em>
3^2 + 4^2 = 5^2
9 + 16 = 25
25 = 25
5^2 + 12^2 = 13^2
25 + 144 = 169
169 = 169
9^2 + 12^2 = 15^2
81 + 144 = 225
225 = 225
