add (4x^2-xy-y^2) and (x^2+5xy+8y^2) simplify your answer:

Answer:

It would be 5949.70

Step-by-step explanation:

The hundreds place is the first two number after a decimal point. In this case it would be 6 and 9. Now if were rounding to the hundredths, you would look at the number right after 9 to see if you could round up. That number happens to be an 8, and if that number is greater than 5, than it will round up the number before it. Now since 8 would round up nine, that would make it a 10, but that can not happen, so you would have to round up the first number as well, which would give you .70.

Answer:

1st choice c>190.29

Step-by-step explanation:

First I subtracted 668 from 2000 ad got 1332. I then divided 1332 by 7 since they are collecting cans on the final 7 days. and got 190.285714286. When I round up the answer I got 190.29. Now I can immediately know that the 2nd choice is wrong. In the first sentence of the question, it said "more than 2,000" so based on that I know it's the answer choice with the greater than sign.

Hope this help you :)

Answer:

the third one or C

Step-by-step explanation:

2000-668=1332

1332÷7= 190.285

round

190.29

C > (pretend their is a line under the >) 190.29

Step-by-step explanation:

-|x|=-8

if we put the value =8

we get,

-|8|=-8

if we put the value =-8

-|-8|=-8

so,

answer of this questions is {-8,8}

Answer:60

Step-by-step explanation:

32 divided by 4 is 8 8 an hour per worker 90 mins is hour and a half 8 times 5 40 each person can make 4 in 30 min so 20

40+20=60

sorry i am a bad explainer

60 widgets can five workers make in 90 minutes.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

4 workers can make 32 widgets in an hour .

1 hour = 60 mint.

now,

4 workers work 60 mint. to make 32 widgets

so, 1 workers work 60 mint. to make =32/4

                                                             =8 widgets

1 workers work 1 mint. to make =8/60 widgets

i.e.  1 workers work 90 mint. to make =8*90/60 widgets

5 workers work 90 mint. to make =8*90*5/60 widgets

solving we get,

5 workers work 90 mint. to make =60 widgets

hence, 60 widgets can five workers make in 90 minutes.

Answer:

I'm pretty sure it is 2ab×(a+3b)

Answer: Yes

The answer is:

Yes, both of this is equivalent.

Step-by-step explanation:

For the reason and solution, here:

1) 4x+6/2+3=

2) 4x+9=

For me, these two is equivalent because "4x+9" equivalent is 2x+6 and this is the same if you simplified 4x+6/2+3 so for me, the answer is yes.

Hope this helps and if you could mark this as brainliest. Thanks!

Answer:

The number one reason why phones are important is to use it as a way of communication. This can help connect people to the outside world & can open up the minds of younger people.

Phones can be great for researching things, & getting projects/homework done.

Answer:

D ( if you add +4 to the (x + 3)^2)

Step-by-step explanation:

Parent function is f(x) = x^2

A translation 3 units left gives y = )x + 3)^2

- and 4 up gives y = (x + 3)^2 + 4 - vertex form.

Standard form :

y = x^2 + 6x + 9 + 4

= x^2 + 6x + 13.

Answer:

y = 23x + 10

y = 28x + 0

Step-by-step explanation:

Given that:

Miguel :

Velocity = 23 km/hr

Starting position = 10 miles

Gabby:

Velocity = 28 km/hr

Starting position = 0 miles

The general form of a linear equation :

y = mx + c

In the scenario above ; the starting points corresponds to the intercept, c

The distance moved per hour (velocity) is the slope (m), which is the change in y per unit change in x

Hence ;

Miguel:

y = 23x + 10

Gabby:

y = 28x + 0

Answer:

The distance between A and B is 2.6

Step-by-step explanation:

We know that there are 2 whole numbers from -1 to 0 and 0 to 1. Then we can add the 0.3 from both sides. 0.3 plus 0.3 is 0.6.

Answer:

27 cm or 2in and 6cm!

Step-by-step explanation:

count the lines.

Answer:

0

Step-by-step explanation:

You start off with 2x + 2x + 2 = 4x + 2.

You would then add like terms, as shown below.

4x + 2 = 4x + 2

Now, you would subtract 4x from both sides, and that would leave you with:

2 = 2

You would now subtract 2 from both sides, which would now leave you with 0.

Answer:

g = 5c

5*c = g

g/5 = c

Step-by-step explanation:

g = grandfather

c = carl

Answer:

The age of Carl's grandfather is a composite number.

Carl's age is a factor of the age of his grandfather.

The number 5 is a factor of the age of Carl's grandfather.

Answer:

y < 1/4x + 3

Step-by-step explanation:

the line is dotted so we know the symbol will not include the "equal to" part

we can also see that the shading in below the y intercept, so we know that the symbol will also be less than

this means the symbol is <

now, create an equation for the line:

we know that the y intercept is 3, and that there is a rise of 1 and a walk of 4

so the slope is 1/4

now put this together and you get 1/4x + 3

this part will go on the right side of the < symbol in your inequality

so now you can create an inequality: y < 1/4x + 3

Answer:

y < [tex]\frac{1}{4}[/tex] x + 3

Step-by-step explanation:

m = [tex]\frac{1}{4}[/tex] and coordinates of y-intercept are (0, 3)

y < [tex]\frac{1}{4}[/tex] x + 3

Just substitute from the first pair then you should get the answer.

Step-by-step explanation:

Let the number of weeks be X.

[tex]743 = x \times 63 + 50 \\ 743 = 63x + 50 \\ 743 - 50 = 63x \\ 693 = 63x \\ x = 693 \div 63 \\ \frac{693}{63} \\ \\ = 11 \: weeks[/tex]

...and by the way myself Zeeshan Khan from India

Answer:

x=7

Step-by-step explanation:

Answer:

5 hours

Step-by-step explanation:

The problem is giving you the equation

y =  0.4x; where y is the # of buckets filled and x is the hours.

If they you 2 filled buckets, then how many hours?  

You need to solve for x

y = 0.4x; to get the x by itself, divide by 0.4

x = [tex]\frac{y}{0.4}[/tex] ; now substitute y with 2 ( for 2 filled buckets)

x = [tex]\frac{2}{0.4}[/tex] = 5; which means it took 5 hours to fill up 2 buckets.
