Answer:

x=19

Step-by-step explanation:

2(x+6)=3(x-4)+5

2x+2*6=3x-3*4+5

2x+12=3x-12+5

12+12-5=3x-2x

19=x

Translate into an algebraic expression: n−1 increased by 110%

lorasvet [3.4K]

Answer:

Part 1) The algebraic expression is equal to $1.10(n-1)$ or $1.10n-1.10$

Part 2) The algebraic expression is equal to $\frac{1.10}{n}$

Step-by-step explanation:

Part 1) we have (n-1) increased by 110%

110%=110/100=1.10

The algebraic expression of (n-1) increased by 110% is equal to multiply 1.10 by (n-1)

$1.10(n-1)$

Distributed

$1.10n-1.10$

Part 2) we have n^(-1) increased by 110%

110%=110/100=1.10

The algebraic expression of n^(-1) increased by 110% is equal to multiply 1.10 by n^(-1)

Remember that

$n^{-1}=\frac{1}{n}$

$1.10(n^{-1})=1.10\frac{1}{n}=\frac{1.10}{n}$

<u>Answer:</u>

x = 20; ∠5 = 120°

<u>Step-by-step explanation:</u>

∠1 and ∠8 are alternate angles and therefore are equal, which means that if m ∠1 = (4x + 40)° and m ∠8 = (2x + 80)°, then 4x + 40 = 2x + 80

Solve for x:

4x + 40 = 2x + 80

2x = 40

x = 20

∠5 is corresponding to ∠1 and vertical to ∠8, therefore equal to both; To find it's measure:

Plug x into either ∠1 or ∠8's respective equations:

2x + 80

2(20) + 80

120

∠5 is 120°
