Answer:

x=(45-15)/3

Step-by-step explanation:

x=scarf price

scarf price= $\frac{45-15}{3}$ = 45-15 ÷ 3

we solve the bracket first so 45-15=30

scarf price= $\frac{30}{3}$ = 30÷3

30÷3= 10

x=10

Travka [436]

Answer:

Report the length as x inches to the nearest quarter of an inch.

See the example below

Step-by-step explanation:

Report the length as x inches to the nearest quarter of an inch.

E.g : If the actual length is 2.4 inches then the reported length would be 2.5 in

Similarly if the actual length is 2.3 inches then the reported length would be 2.25 in

Find the sum of 46 + 42 + 38 + ... + (-446) + (-450)46+42+38+...+(−446)+(−450)

JulijaS [17]

sum of sequence Find the sum of 46 + 42 + 38 + ... + (-446) + (-450) is -25,250

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

We need to find sum of sequence : 46 + 42 + 38 + ... + (-446) + (-450)

Given sequence is an AP with following parameters as :

$a=46\\d=42-46=-4$

So , Let's calculate how many terms are there as :

⇒ $a_n=a +(n-1)d$

⇒ $-450=46 +(n-1)(-4)$

⇒ $-496=(n-1)(-4)$

⇒ $\frac{-496}{-4}=n-1$

⇒ $124=n-1$

⇒ $n=125$

Sum of an AP is :

⇒ $S_n = \frac{n}{2}(2a+(n-1)d)$

⇒ $S_1_2_5 = \frac{125}{2}(2(46)+(125-1)(-4))$

⇒ $S_1_2_5 = \frac{125}{2}(-404)$

⇒ $S_1_2_5 =-25,250$

Therefore , sum of sequence Find the sum of 46 + 42 + 38 + ... + (-446) + (-450) is -25,250
