Complementary angles mean that they would add up to 90 degrees.
That means 2x-0 and 3x-10 added up together would equal to 90 degrees.
2x-0+3x-10 = 90
5x-10 = 90
5x = 100
x = 20
Answer:
c = 3(b + 1)
Step-by-step explanation:
c = 4b - 1b + 3
4b - 1b = 3b
c = 3b + 3
3 is a common factor of both terms on the right hand side
Factorizing the expression
c = 3(b + 1)
Step-by-step explanation:
35%= 650+50
=700
1%= 700÷35
= 20
100%=20×100
= 2000
Answer:
1.
Step-by-step explanation:
The cell phone experiments an exponential depreciation, which is defined by the following formula:
, for . (1)
Where:
- Initial cost, measured in monetary units.
- Depreciation rate, no unit.
- Time, measured in years.
- Current value of the cell phone, measured in monetary units.
If we know that and , then the exponential decay function that represents the situation is:
Which means that correct answer is 1.
Answer:
The first step to simplify any expression is by removing the brackets if there is anyone and in the other hand by removing the parenthesis like in this case
Step-by-step explanation:
First one must apply the distributive property multiplying the variable -x by all the subjects in the parenthesis like 2 and -3x in this case to get -2x and 6x^2, remember to apply the property of signs multiplication in all the cases.
