Answer: n=-36
Step-by-step explanation:
Let the number be n
2 fewer than a doubled number can be written as 2n-2
The number decrease by 38,can be written as n-38
Equate both
2n-2=n-38
Collect like terms
2n-n=-38+2
n=-36
The number is -36
Answer:
It takes 60 miles driven with company B for charge as much as company A
Step-by-step explanation:
Company A = $ 117 with unlimited mileage.
Company B = $ 75 + (m × $0,70)
Let's find the number of miles driven in company B for charge as much as company A:
$ 75 + (m × $ 0,70) = $ 117
m × $ 0,70 = $ 117 - $ 75
m = $ 42/ $0,70
m = 60 miles
Hey there! I'm happy to help!
The additive inverse is when you switch the sign. The additive inverse of 4x is -4x. A number added to its additive inverse is equal to 0.
The multiplicative inverse is also known as the reciprocal, and it is where you flip the numerator and denominator. If you multiply a number by its reciprocal, it equals 1. The multiplicative inverse 4x would be 1/4x.
The additive inverse is -4x.
The multiplicative inverse is 1/4x.
Have a wonderful day! :D
Answer:
∠3 = 34°
Step-by-step explanation:
There are (at least) two ways you can get there:
- ∠3 is complementary to ∠6, which is a vertical angle with ∠1. So, ∠3 = 90°-56° = 34°
- ∠3 is complementary to ∠4, which is a corresponding angle with ∠1. So, ∠3 = 90°-56° = 34°.
