Answer:
x=-2, y=5. (-2, 5).
Step-by-step explanation:
2x+9y=41
-4x+y=13
---------------
2(2x+9y)=2(41)
-4x+y=13
-----------------------
4x+18y=82
-4x+y=13
------------------
19y=95
y=95/19
y=5
2x+9(5)=41

Alfred owns land that has an area of x²-25. His neighbor Grace is selling him the land she owns so he can combine them into one big property. Her land has an area of x²+3x+2. PART A-4pts Factor the expressions that represent Alfred's land and Grace's land to find the Dimensions of each property.
Answer:
Step-by-step explanation:
Area of Alfred's land = (x²- 25)
Factors of given expression = (x - 5)(x + 5)
Therefore, Alfred's land will have the dimensions (x - 5) and (x + 5).
Area of his neighbor's land = x² + 3x + 2
Factors of the given expression = x² + 2x + x + 2
= x(x + 2) + 1(x + 2)
= (x + 1)(x + 2)
Therefore, dimensions of Grace land will be (x + 1) and (x + 2).

Step-by-step explanation:
Abby has 15/20 on her quiz, and we can convert that to 0.75. We can turn 0.75 into 75 points in her quiz.
Jesse has 18/30 on her quiz, and we can convert that to 0.60. We can turn 0.60 into 60 points in her quiz.
0.75 > 0.60, so Jesse has more.

A jar contains 4 red marbles, 8 blue marbles, and 2 green fond the probabillity of picking a red marbles, replacing the item, and then picking a blue marble?
Answer:
8/49
Step-by-step explanation:
Given data
Sample space
4 red marbles
8 blue marbles
2 green
Sample size
4+8+2 = 14
Pr(picking a red)
Pr(red)= 4/14= 2/7
With replacement
Pr(picking a blue)
Pr(blue)= 8/14= 4/7
Hence the probability of picking a red marble, replacing the item, and then picking a blue marble
= 2/7*4/7
= 8/49

What is the solution to this system of equations using elimination. -7x -8y =9 and -4x + 9y = -22
Answer:
x = 1
y = -2
Step-by-step explanation:
We have the system of equations:
-7*x - 8*y = 9
-4*x + 9*y = -22
To solve this type of system, we need to start by isolating one of the variables in one of the equations.
I will isolate the variable x in the first equation to get:
-7*x - 8*y = 9
-7*x = 9 + 8*y
x = (9 + 8*y)/(-7)
x = -(9 + 8*y)/7
Now we can replace this in the other equation to get:
-4*(-(9 + 8*y)/7) + 9*y = -22
And now we can solve this for y, we will get:
(4/7)*(9 + 8*y) + 9*y = -22
(4/7)*9 + y*(9 + 8*(4/7)) = -22
y*(63/7 + 32/7) = -22 - (36/7)
y*(95/7) = -(22*7/7) - (36/7)
y = (7/95)*(-(22*7/7) - (36/7)) = (-22*7 - 36)/95 = -2
y = - 2
Now we can replace this in the equation x = (9 + 8*y)/(-7) to find the value of x:
x = (9 +8*(-2))/(-7) = 1
Then the solution for the system is the pair (1, -2)
That means:
x = 1
y = -2
. Which combinations hold the same amount of liquid as a 14-cup jug? A. 2-quart bottles and 4-pint bottles B. 3-quart bottles and 2-cups C. 1-quart bottle and 6-pint bottles and 2-cups D. 1-quart bottle and 10-cups E. 2-quart bottles and 2-pint bottles and 2-cups
Answer:
B, D, and E
Step-by-step explanation:
8 oz = 1 cup
1 qt = 32 oz
1 pint = 16 oz
14 cups = 8 x 14 = 112 oz
A) 64 + 64 = 128 no
B) 96 + 16 = 112 yes
C) 32 + 96 + 16 = 144 no
D) 32 + 80 = 112 yes
E) 64 + 32 + 16 = 112 yes

2/3•x-9=12 solve for x?
Answer:
31.5
Step-by-step explanation:
Ok.
2/3x - 9 = 12
2/3x = 21
x = 21*(3/2)
x = 63/2 = 31.5
Answer:
[tex]x=\frac{63}{2}[/tex]
Step-by-step explanation:
[tex]\frac{2}{3} \times x-9=12[/tex]
Add 9 to both sides:
[tex]\frac{2}{3}x-9+9=12+9\\\frac{2}{3}x=21[/tex]
Multiply both sides by 3/2:
[tex](\frac{3}{2} )\times(\frac{2}{3}x)=(\frac{3}{2} )*(21)\\x=\frac{63}{2}[/tex]
x = 63/2 is your answer.
