They are -9 and 8. because since 9 times 8 is 72, you need the 9 to be negative to add to -1

Abby and Annie have the same number of coins.
svetlana [45]

Answer:

2400 coins

Step-by-step explanation:

What we should do is calculate the  Least Common Multiple of 80 and 75, since each of us put together a group with this amount of coins, this way we will know the amount of coins when they are equal.

To obtain the L.C.M

you have to factor both numbers and multiply the numbers whose exponent is the highest, it looks like this:

75 = 5 ^ 3

80 = 2 ^ 4 * 5

We multiply those with the highest exponent,

5 ^ 3 = 75

2 ^ 4 = 16

75 * 16 = 1200.

L.C.M. is 1200.

Since they tell us that they have less than 2000 coins, this is the correct answer, because when assembling these groups in this way, they coincide again in 2400, which is over the limit.

So, each one has 1200 coins, in total it would be:

1200 * 2 = 2400

Between them they have a total of 2400 coins

HELP ME ITS TIMED AND I WILL GIVE BRAINLIEST!!!!!
Olegator [25]

To find the gradient of a line we first hv to find the formula

so Gradient=√X1-x2and √y1-y2

((-2,1) and (0,-5)) line 1

line 2(0,-1) and (1,0)

first we will work for line 1

X1 is -2

X2 is -0

Y1 is 1

Y2 is -1

so y=x-1

so we substitute the values

1--1=-2--0

so,

1+1=-2+0

2=-2

-0

So the equation 1 line 1 is not true

we will now go to equation 2 line 2

the equation is 3x+y=-5

we substitute the values

3(-2--0)+1--1=-5

3(-2)+-2=-5

-6+-2=-5

-8= -5

group like terms

Ur answer should look like this -3

So the answer is 3x+y=-5

Which is the choice to the inequality below? <br> x/6&gt;7
romanna [79]

Answer:

x > 42<em />

Step-by-step explanation:

\frac{x}{6} > 7

<em>Multiply 6 on both sides. </em>6(\frac{x}{6}) > 6(7).

<em>Simplify it. </em>x > 42<em />

Therefore, the answer is x > 42.

Hope this helped! If not, please let me know! <3

BIG POINTS! Please help me with this math problem. By the way, the answer is not 1 / 128 .
vodomira [7]

Answer and Step-by-step explanation:

2 * 2 * 2 * 2 * 2 * 2 * 2 = 128

2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 = 1024

4 * 4 * 4 * 4 * 4 = 1024

8 * 8 = 64

\frac{128 - 1024}{1024 - 64}

\frac{-896}{960}

896 and 960 both have 64 in common.

896 divided by 64 equals 14.

960 divided by 64 equals 15.

-\frac{14}{15} is the answer.
