noname [10]
Answer: The Tree is 28 ft tall

How do we know this. To solve this problem we can use proportions.

4 
→ 3.5

x → 24.5

So now our unit number can be found doing 24.5 ÷ 3.5 = 7 So x ÷ 4 must also equall 7. 

We can make equation: x ÷ 4 = 7

Know we can use our knowledge of finding x.

x = 7 × 4
x = 28

The tree is 28 ft tall.

Lets check our answer!

4 
→ 3.5

28 → 24.5

4 * 7 = 28

3.5 * 7 = 24.5

What is the reason: if a+c=b+c then a=b
Tomtit [17]

Step-by-step explanation:

Example 1:

a+c=b+c then a=b

First let the value of a and b be different (not equal)

a=5

b=7

c=10

a+c=b+c

5+10=7+10

15≠17

Example 2:

Let the value a and b be equal (the same)

a=5

b=5

c=10

a+c=b+c

5+10=5+10

15=15

So when,

a+c and b+c is equal, a and b are <u>always</u><u> </u> equal.

Hope this helps ;) ❤❤❤
