-5+x/3=-11

Answers

Answer 1

Answer: add 5 to both sides
5-5+x/3=5-11
0+x/3=-6
x/3=-6
times both sides by 3
3x/3=-18
x=-18

The price of one share of Acme Company declined $3.50 per day for 4 days in a row. What is the overall change in price of one share?

Answers

Answer:

The overall change in price of one share is: -$14.00

Step-by-step explanation:

The Acme Company share has declined its price in a rate of $3.50 per day

Therefore the change rate is: $- (\mathdollar 3.50)/(day)$

In order to find the overall change in prince in 4 days in a row, we must have to multiply the change rate by 4 days

$( - (\mathdollar 3.50)/(day))(4 \ days)= - \mathdollar 14.00$

Therefore, the overall change in price is: -$14.00

Since it's a decline, the amount will be negative.
3.5 per day for 4 days so multiply 3.5 by 4, which equals: $14
so the overall change is -$14.00

find a two-digit number such that three times the tens digit is 2 less than the unit's digit and twice the number is 20 greater than the number obtained by reversing the digits.

Answers

Let's name these two digits as a (tens digit) and b (units digit) and then rephrase the problem statement using a and b.

The part of the sentence "three times the tens digit is 2 less than twice the units digits" translates into:

3a = 2b - 2

Considering that both a and b have to be integer numbers less than 10 and that a will have to be an even number

(since 2b - 2 is always even and for 3a to be even, a will have to be even),

the only possible options that will satisfy this equation are: 47 and 24.

The second part of the problem statement does not make much sense.

What exactly is twice the number obtained by reversing the digits?

In case of 47, twice the number obtained by reversing the digits is 2*74 = 148.

In case of 24, twice the number obtained by reversing the digits is 2*42 = 84.

What is 10 3/4 - 7 1/4 ? KEEP THIS AS A FRACTION ! DO NOT PUT AS A DECIMAL !

Answers

There are several ways to do this but the way I'm going to do it is as follows
Change the fractions into improper fractions
Multiply the denominator by the whole number then add the numerator
$10 (3)/(4)$ ⇒ $(43)/(4)$
$7 (1)/(4)$ ⇒ $(29)/(4)$
You subtract the numerators
$(43)/(4)$ $- (29)/(4)$ = $(14)/(4)$
You then divide the numerator(top) by the denominator(bottom)
14÷4= $3 (2)/(4)$ ⇒ $3(1)/(2)$

$10(3)/(4)\to (43)/(4) \n\n 7(1)/(4)\to(29)/(4) \n\n\n 10(3)/(4)-7(1)/(4)=\n\n= (43)/(4)-(29)/(4)= \n\n = (14)/(4)= \n\n =\boxed{(7)/(2)}$
