3.57x + 1.61 = 4.71 + -2.63x
Reorder the terms:
1.61 + 3.57x = 4.71 + -2.63x
Solving
1.61 + 3.57x = 4.71 + -2.63x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2.63x' to each side of the equation.
1.61 + 3.57x + 2.63x = 4.71 + -2.63x + 2.63x
Combine like terms: 3.57x + 2.63x = 6.2x
1.61 + 6.2x = 4.71 + -2.63x + 2.63x
Combine like terms: -2.63x + 2.63x = 0.00
1.61 + 6.2x = 4.71 + 0.00
1.61 + 6.2x = 4.71
Add '-1.61' to each side of the equation.
1.61 + -1.61 + 6.2x = 4.71 + -1.61
Combine like terms: 1.61 + -1.61 = 0.00
0.00 + 6.2x = 4.71 + -1.61
6.2x = 4.71 + -1.61
Combine like terms: 4.71 + -1.61 = 3.1
6.2x = 3.1
Divide each side by '6.2'.
x = 0.5
Simplifying
x = 0.5

Answer:
the slope of the line is 4/5
Step-by-step explanation:
an equation parallel to that is y= 4/5 - 3
Slopes are the same = parallel
Answer:
4/5 is the slope of the other line parallel to this y=4/5x+1
Step-by-step explanation:
What is the slope of the line passing through (-3, 5) and (5, -3)?
no slope
slope = 0
slope = 1
slope = -1
Answer:
The Slope = -1
Dear journal, I'm not an outdoorsy kind of girl, but when my neighbor Adelle invited me to go camping, I could hardly tell her I was afraid of bears and snakes and pretty much any wild animal. I had images of waking up in the middle of the night, my tent shaking to the rhythm of growls. I couldn't let Adelle know I was afraid. So, I packed my bags and waited at the door the morning we were to leave. To my great surprise, I discovered that camping isn't at all how I imagined. The park ranger assured us that no bears had been seen in the last five years, and to my great surprise, Adelle's family had a pop-up camper, so we weren't even in a tent. Adelle did get to see my true colors, though, when we were hiking. We came across a snake in the middle of the trail, and I've never run so fast in my life. Snakes aside, camping's not so bad. What techniques could be used to improve this sample diary entry to make it interesting and effective at sharing the experience? Check all that apply. adding reasons why the speaker was afraid adding some dialogue adding more description about what was enjoyable about the camping trip adding more information about bears adding a description of the pop-up camper

Answer: 11/15
Hope this helps! ^^
Answer: The answer in improper form is 11/15 or in mixed number form it is 12 1/5... I did this by dividing the Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
2/3 * 11/10
For fraction multiplication, multiply the numerators and then multiply the denominators to get
2*11/3*10= 22/30
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 22 and 30 using 22 divided by 2/30 divided by 2 which equals 11/15.
Therefore 2/3 divided by 10/11 equals 11/15
Hope this helps... Plz mark me brainliest... Stay safe and have a great weekend!!! :D

Mr. Birdie has worked hard as a Math teacher all his
life and has saved 42 a million dollars. A savings bank
has offered him 4% interest per annum on his savings.
Mr Birdie is retiring at 65 and wants enough to live on
until his 90th birthday. He figures that he will have
$1666.66 a month.
Can you explain where his calculation may have come
from if it is correct. Explain your thoughts in the box
below.
Answer:
You'll likely need assets worth 10 to 16 times your salary by the time you leave your job. A 45-year-old making $120,000 who hopes to retire at age 60, say, should already have nearly $700,000 set aside. (See the Retire Early calculator.) You can get by with less if you'll have other sources of income.
Last season, a pair of jeans cost $42.95. This season, the price of the jeans increased by 25 percent. Later in the season, the jeans were put on sale for 25 percent off. First, guess. What do you think the sale price will be? Why? Then, calculate: How much did the jeans cost at the beginning of this season? What was their sale price? Did you get the sale price you were expecting? Why or why not? Consider what the jeans would cost if they had gone on sale by 25% first, and then had their price increased by 25%. First guess. What do you think the jeans will cost this time? Why? Then, calculate: How much will the jeans cost this time? Did you get the answer you were expecting? Why or why not?
Answer:
42.95 first price hiked 25%, then discounted by 25% : Final price = 40.28
42.95 first discounted by 25%, then price hiked by 25% : Final price = 40.27
Both are same (approx) because of same mathematical treatment
Step-by-step explanation:
If Jeans price first hiked price by 25%, then gone on sale by 25%Last season price = 42.95
This season increase in price = 25% of 42.95 = 10.73
Jeans price at beginning of this season = 53.68
Discount on sale price, this season = 25% of 53.68 = 13.42
Discounted jeans price this season = 53.68 - 13.42 = 40.28
If Jeans price first gone on sale by 25%, then price increased by 25%Last season price = 42.95
Discount on previous price = 25% of 42.95 = 10.73
Jeans price this season = 42.95 - 10.73 = 32.22
Price hike this season = 25% of 32.22 = 8.05
New jeans price this season = 32.22 + 8.05 = 40.27
The same answer is got in both cases. As, mathematically, they are same. 1st : 75% of (125% of 42.95) & 2nd : 125% of (75% of 42.95)Which distributive property gives the same answer as 7(99)?
7(99+9)
o 7(99-9)
. 7(100+1)
7(100-1)
Answer:
7(100-1)
Step-by-step explanation:
That's it right there
A PAIR OF JEANS MARKED AT R450 IS SOLD AT DISCOUNT OF 25%.
Original price is the jeans = Rs450
Discount = 25%
Discount amount
= 25% of 450
= 25%(450)
= 25/100 × 450
= 25/10 × 45
= 5/2 × 45
= 225/2
= Rs112.5
Price after discount
= original price - discount amount
= 450 - 112.5
= Rs337.5

Megan's commute to work includes an 8-mile drive and a 21-mile train ride. This expression can be used to find the total time it takes Megan to get to work, where xis her average driving speed in miles/hour. 21
Answer:
(8 / x) + (21 / y)
Step-by-step explanation:
Given that:
Average driving speed = x mph
Miles driven to work = 8 mile
Miles by train to work = 21 miles
Average train speed = y
Total time taken to get to work. :
Recall : time taken = distance / speed
Hence,
Time taken =) total distance / average driving speed)
Total time taken = (8 / x) + (21 / y) hours
Total time taken = (8 / x) + (21 / y) hours
Answer: The average speed of the train is represented by x+20. When Megan drives at an average speed of 45 mph, it takes her approximately 0.50 hour to get to work.

Find the GCF of the given polynomial. 16a^4b^4 + 32a^3b^5 - 48a^2b^6
Answer:
[tex]16a^2b^4[/tex]
Step-by-step explanation:
GCF= Greatest Common Factor
Given a polynomial, the GCF is the largest polynomial that will divide evenly into that polynomial.
The polynomial is
[tex]16a^4b^4 + 32a^3b^5 - 48a^2b^6[/tex]
First, we find the GCF of the coefficients:
16, 32, 48
Since 32 and 48 are multiples of 16, 16 is the GCF of the coefficients.
Now we select all the repeating variables with their smallest exponent:
[tex]a^4, a^3, a^2.\ GCF= a^2[/tex]
[tex]b^4, b^5, b^6.\ GCF=b^4[/tex]
The GCF of the polynomial is
[tex]\boxed{16a^2b^4}[/tex]
