Step-by-step explanation:
So, we will take one of the numbers = x
And the other is 12 more than 3 times it, so = 3x + 12
So they said if we add them, we will get 4
So x + (3x + 12) = 4
4x + 12 = 4
4x = 4 - 12
4x = - 8
x = - 8 ÷4
x = - 2
So one of the numbers x = - 2
The other is 3x + 12
So x = - 2
3x +12 = 3(-2) + 12
= 6
So the 2 numbers = 6 and - 2
Lets check!
6 + (-2) = 4
So it's right!
Answer:
16.6 feets .
Step-by-step explanation:
Length of wire = 30 feets
Distance between base of tree and ground = 25 feets
Height of tree, h
Using Pythagoras rule :
h² = 30² - 25²
h² = 900 - 625
h² = 275
h = sqrt(275)
h = 16.583
h = 16.6 feets
Height of tree is 16.6 feets
Answer:
6
Step-by-step explanation:
16 is 10 +6, and 34 is 30+4
10*30=300
10*4=40
6*30=180
4*6=24
add them up: 300+40+180+24=544
