Answer:
- 2xy = 6
Step-by-step explanation:
x = - 11 - 4y → (1)
2x - 3y = 11 → (2)
Substitute x = - 11 - 4y into (2)
2(- 11 - 4y) - 3y = 11 ← distribute parenthesis and simplify left side
- 22 - 8y - 3y = 11
- 22 - 11y = 11 ( add 22 to both sides )
- 11y = 33 ( divide both sides by - 11 )
y = - 3
Substitute y = - 3 into (1)
x = - 11 - 4(- 3) = - 11 + 12 = 1
solution is (1, - 3 )
Then
- 2xy = - 2 × 1 × - 3 = 6

Answer:
y=5/2x+13.5
Step-by-step explanation:
5x-2y=10
-2y=-5x+10
y= 5/2x-5
y-6=5/2(x+3)
y-6=5/2x+ 7.5
y=5/2x+13.5
Answer:
Step-by-step explanation:
First you must isolate y in the given equation
5x - 2y = 10 Subtract 5x from both sides
-2y = -5x + 10 Divide both sides by - 2
y = -5/-2 x + 10 / -2
y = 2.5 x - 5 The new equation has a slope of 2.5
x = - 2
y = 6
y = 2.5x + b
6 = 2.5*-2 + b
6 = -5 + b Add 5 to both sides
6+ 5 = b
b = 11
Answer: y = 2.5x + 11

When two number cubes are rolled, what is the probability of getting 5 or 4 as the product of the two numbers
Answer:
5/36
Step-by-step explanation:
number cubes are rolled = dies that have 6 faces with numbers 1,2,3,4,5,6
Getting 5 or 4 as the product of the two numbers.
How many ways we can get 5 or 4 as a product?
5 ways : 1*4, 1*5, 2*2, 4*1, and 5*1
All possible outcomes are 36 (see table)
P = ways to get 4 or 5 as a product/ all possible ways = 5/36

The sum of three numbers is 164. The second number is 3 more than twice the first number, and the third number is four times the first number. What are the three numbers
Answer:
23, 49, and 92
Step-by-step explanation:
three numbers x, y, z
x+y+z=164
y=2x+3
z=4x
we have three equations and two of them are in terms of x so we can solve for x first by plugging in the two equations to our first equation
x+2x+3+4x=164
7x+3=164
7x=161
x=23
then find y
y=2(23)+3=46+3=49
then find z
z=4(23)=92
