What are the 4 lowest numbers to average 80 percent . (Lowest possible and one of the numbers has to be 60)

Simplified :(5x+4y)(5x−4y)

=(5x+4y)(5x+−4y)

=(5x)(5x)+(5x)(−4y)+(4y)(5x)+(4y)(−4y)

=25x2−20xy+20xy−16y2

=25x2−16y2

hope this helps!

Answer:

25x^2-16y^2

Combine the opposite terms in  5x(5x)+5x(4y)-4y(4y)

                                                            5x(5x)-4y(4y)

                                                             25x^2-16y^2

Answer:

7 hours

Step-by-step explanation:

This is because 24/3=8

48/4=12

168/12=14

168/8=21

21-14=7

It take him 7 hours to earn the money if he only does yardwork for his grandmother.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given that Leroy wants to buy a new racing bicycle that costs $168. He earns $24 for 3 hours of yardwork and he earns $48 for 4 hours of babysitting.

We need to find the time take to earn the money if he only does yardwork for his grandmother.

Thus, $24 for 3 hours of yardwork

24/3=8

Again, $48 for 4 hours of babysitting.

48/4=12

Now, 168/12=14

168/8=21

The time difference is;

21-14=7

Answer:8/9

Step-by-step explanation:4/3 * 2/3=8/9

The simplification of the fraction 1 1/3 x 2/3 in the simplest form will be; 8/9

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We have been given the mixed fraction as;

[tex]1 \dfrac{1}{3} \times \dfrac{2}{3}[/tex]

First, we need to simplify the mixed fraction;

[tex]1 \dfrac{1}{3} =\dfrac{4}{3}[/tex]

Therefore, the product of the fraction will be;

4/3 x 2/3 = 8/9

Hence, the simplification of the fraction 1 1/3 x 2/3 in the simplest form will be; 8/9

Step-by-step explanation:

Bcs when u have a closed circle is when is less or equal to, and an open circle means greater/less to.  And you have a closed bcs is less or equal to. So u look in the answers, you can already take two answers out which are the 2 and the 3 bcs they are open circle. Then x ≥ 98.6, then x is bigger than the 98.6 so the arrow would go to the right. And the answer would be first one

(How to do that in an easier way, Look at this ≥, the pointy side is aiming in the right so the arrow will go always to the right, THIS ONLY WORKS WHEN THE LETTER IS IN THE LEFT {EX. y ≤ 19, the arrow will be pointing in the left.)

Step-by-step explanation:

Answer:

-5040

Step-by-step explanation:

Start inside out.

1) -72/-2=36 now this is still inside the braces so you have to multiply times 2

2)36*2= 72 and now remember that negative times negative is positive

3)72*7=504

multiplies times -10= -5040

You can also think about this another way

(-72/-2)(2) the two's go away and you stay with -72/-1, wich is equal to 72 and then multiply that by 7 and them times -10.

Option D. is the correct answer.

The function that can be used to find f, the amount of money Lisa will have saved is F = 6d + 50

Step-by-step explanation:

From the question,

Lisa is saving $50 that she received from her grandmother,

Also, she earns $6 each time she walks her neighbor's dog, which she also saves.

Now, to determine the function that can be used to find the amount of money Lisa will have saved after walking the neighbor's dog d times, we will determine how much she will earn from walking the dog d times and then add it to the money she received from her grandmother. \

If she earns $6 each time she walks her neighbor's dog, then

she will earn $6×d if she walks the neighbor dog for d times.

$6 × d = $6d

Hence, she will earn $6d from walking the dog d times.

The total amount she will have saved will be $6d + $50.

Hence, the function that can be used to find f, the amount of money Lisa will have saved is F = 6d + 50.

Option D. is the correct answer.

the thang

Answer:

Step-by-step explanation:

To start solving this problem, you need to figure out how many Pounds( I'll use lbs.) = 5 Tons( I'll use T).

2,000 lbs. = 1 T.

X 5               X 5

10,000 lbs. = 5 T.

Now we divide. That just means that if we know that 1 person( I'll use P) = 150, we just divide 5 T( 10,000 lbs.) by 150 lbs.

10,000/150=66.6666666667
