4x-10>1000. Hope this helps!:)
Answer:
x=12
Step-by-step explanation:
Both these angles are *supplementary* to each other, this means that (10x-20) and (6x+8) will both equal 180 degrees.
1. Add 10x - 20 and 6x + 8 together
By adding them together, you get 16x - 12
2. Since both of them added together would also equal 180, this means that 16x - 12 = 180
3. Use the additive inverse property and add 12 to both sides. This gives you 16x = 192
4. In order to isolate x, divide 16 on both sides.
192/16 = 12
Therefore, x is 12
Answer:
Step-by-step explanation:
We are given the following formula, used to calculate the value of an used car according to the years after the car was originally bought:
Where is the price of the car when it was bought new, and is the number of years the car was used.
Solving the formula with the given data:
This is the value of the car according to the formula.
However, this value can be approximated to:
ΔABC is similar to ΔDEF
Try to pair up all the similar sides.
AB = 15 cm
DE = ? cm
BC = 18 cm
EF = 6 cm
Now all you have to do is find out how the triangles are similar.
18/6 = 3
This means that triangle ABC is 3 times bigger than DEF.
15/3 = 5
So the answer is:
B. 5 cm
If your asking if it is a pattern then yes
