Answer:
a(3x-8)=0
a=0 and b=8/3
Step-by-step explanation:
This second line is not necessarily true. We could have a=0 OR x=8/3. They don't both have to be 0.
144+64= 178
a^2+b^2= c^2
Whenever finding a missing length use the formula up above :
a^2+b^2= c^2
a^2-b^2= c^2
144-64= 80
Answers are 13.3 and 8.9
$3150 because 9% of $25000 is $2250 and 15% of $6000 is 900 and 2250+ 900 is 3150
A decimal equivalent to another decimal is the same number but with more zeros on the right hand side.
0.68 = 0.680 = 0.6800 = 0.68000 etc.
0.9 = 0.90 = 0.900 = 0.9000 = 0.90000 etc.
Just pick whichever two numbers you like :)
Answer:
140
Step-by-step explanation:
<u>As per picture:</u>
∠PTQ and ∠RTS are vertical angles and they are equal
- ∠PTQ = (x + 28)°
- ∠RTS = (2x + 16)°
- ∠PTQ = ∠RTS
- x + 28 = 2x + 16
- 2x - x = 28 - 16
- x = 12
∠PTR is supplementary with ∠PTQ and their sum is 180°
- ∠PTQ = 12 + 28 = 40°
- ∠PTR = 180 - 40 = 140°
