Su has 5 times as many marbles as Bertha. When Su gives Bertha 10 marbles, they have the same amount. How many marbles did they EACH have at the begining? How many did they EACH have at the end?

Answers

Answer:

Part A)

The number of marbles that Su has at the beginning is $25$

The number of marbles that Bertha has at the beginning is $5$

Part B)

The number of marbles that Su has at the end is $15$

The number of marbles that Bertha has at the end is $15$

Step-by-step explanation:

Let

x------> number of marbles that Su has at the beginning

y------> number of marbles that Bertha has at the beginning

we know that

$x=5y$ ----> equation A

$x-10=y+10$ ----> equation B

substitute equation A in equation B

$(5y)-10=y+10$

$4y=20$

$y=5$

Find the value of x

$x=5(5)=25$

Part A) How many marbles did they EACH have at the begining?

The number of marbles that Su has at the beginning is $25$

The number of marbles that Bertha has at the beginning is $5$

Part B) How many did they EACH have at the end?

$x-10=y+10$

$25-10=5+10$

$15=15$

therefore

The number of marbles that Su has at the end is $15$

The number of marbles that Bertha has at the end is $15$

It is d because it matches up exactly to each of the repeating numbers and it shows teh correct amount of x's for each number

Point A is at (3, 2.5) and point B is at (3, 1.4) on a coordinate grid. The distance between the two points is ____. Input numbers and decimal point only, such as 5.8

Answers

Answer: 1.1 units

Step-by-step explanation:

We know that the distance between any two points (a,b) and (c,d) is given by :-

$D=√((d-b)^2+(c-a)^2)$

Then , the distance between the points A (3, 2.5) and B (3, 1.4) will be :-

$D=√((1.4-2.5)^2+(3-3)^2)\n\n\Rightarrrow D= \sqrt{{(-1.1)}^2+0^2}\n\n\Rightarrow D =√(1.1^2) \n\n\Rightarrow D =1.1$

Hence, the distance between the two points is 1.1 units.

The Answer Is , 2.5-1.4 = 1.1

Which ordered pair is the solution to the system of equations?x+y=-1
x-3y=11

A.
(2, −3)

B.
(−2, 1)

C.
(5, −2)

D.
(−6, 5)

Answers

To find the solution, we use the substitution method.

x+y=-1
x-3y=11

x+y = -1-y
-y

x = -1-y

Now apply the value of x into the other equation.

x-3y=11
-1-y-3y = 11

Combine like terms

-4y -1 = 11
+1 +1
-4y = 12

-4y = 12
-4y/-4 = 12/-4
y = -3

Now, apply the value of Y to one equation to find x.

y = -3

x -3 = -1
+3 +3

x= 2

Now we have the value for both, x and y.
x = 2
y =-3

Final answer: A. (2, −3)

which of the following mesurments are greater than 130 fluid ounces. 5 quarts, 16 cups, 9 pints, 2 gallons or 1 gallon

Answers

130 fluid ounces to quarts is 4.06, so 5 quarts is larger.

130 fluid ounces to cups is 16.25, so 16 cups is smaller.

130 fluid ounces to pints is 8.13, so 9 pints is larger.

130 fluid ounces to gallons is 1.02, so 2 gallons is larger and 1 gallon is smaller.

9 pints i'm pretty sure i'm right hope i helped
