Answer:
{x,y} = {25/9,23/9}
Step-by-step explanation:
// Solve equation [2] for the variable x
[2] x = -4y + 13
// Plug this in for variable x in equation [1]
[1] 5•(-4y+13) + 2y = 19
[1] - 18y = -46
// Solve equation [1] for the variable y
[1] 18y = 46
[1] y = 23/9
// By now we know this much :
x = -4y+13
y = 23/9
// Use the y value to solve for x
What is the probability of rolling a one on the first die and a six on the second die?
Write your answer as a fraction or a whole number. With fractions, use a slash ( / ) to separate the numerator and denominator.
The probability of rolling a one on the first die and a six on the second die is 1/36.
What is probability?Probability measures the likelihood or chance of an event happening.
A number between 0 and 1, where 0 represents an impossibility and 1 represents certainty, is used to express it.
By dividing the number of favourable outcomes by the total number of possible outcomes, one can determine the probability of an event.
The probability of rolling a one on the first die is 1/6, and the probability of rolling a six on the second die is also 1/6.
Since the two events are independent, we can use the multiplication rule of probability to find the probability of both events occurring together:
P(rolling a one on the first die and a six on the second die) = P(rolling a one on the first die) × P(rolling a six on the second die)
= (1/6) × (1/6)
= 1/36

if 60% of a number is 120 and 25% of the same number is 50 find 85% of that number
PLEASE HELP!
CORRECT= BRAINLIEST
Answer:
170 is 85% of the unknown value
Step-by-step explanation:
If 60% equals 120, and 25% equals 50. Then all we have to do is add 120 + 50. Since the percents add up to 85%. So your answer is 170. (pretty sure)
Heather, Jim, and Felipe served a total of 90 orders Monday at the school cafeteria. Felipe served 3 times as many orders as Heather. Jim served 5 more orders than Heather. How many orders did they each serve?
Answer:
Heather served 10 orders.
Felipe served 30 orders.
Jim served 50 orders.
What we know:
Let's refer to each person by their first initial (H, J, & F)
H + J + F = 90
F = 3 * H
J = 5 * H
Substitution:
Let's replace F and J by their equivalents in relation to H (basically making the entire left side only H)
H + (5 * H) + (3 * H) = 90
H + (5H) + (3H) = 90
9H = 90
H = 90/9
H = 10
Final Calculations
Now that we know how many orders Heather served, we can calculate how many Jim and Felipe served
F = 3 * H
F = 3 * 10
F = 30
J = 5 * H
J = 5 * 10
J = 50

Dustin wants to create a large mural to cover part of his wall. He drew a sketch of his design to determine the amount of canvas he needs. The area of the design was 0.3 square feet. If the actual mural will have dimensions 5 times that of the design, how many square feet of canvas will Dustin need?
Answer:
7.5
Step-by-step explanation:
[tex]\sqrt{0\\.3}[/tex] = 0.5477225575
Multiply it by 5

Dustin would need 7.5 square feet of canvas.
What is Dilation?Dilation is a type of transformation where the figure is enlarged or made smaller such that it preserves the shape but not size.
Every dilated image are similar figures to the original figure.
The sketch that Dustin drawn is the dilated version of the actual mural.
Area of the design that he sketched = 0.3 square feet
Let l and w be the length and width of the design he sketched.
l × w = 0.3 square feet
Given that, the actual mural will have dimensions 5 times that of the design.
Then the length and width of the actual mural will be 5l and 5w.
Area of the actual mural = 5l × 5w
= 25 × l × w
= 25 × 0.3
= 7.5 square feet
Hence the square feet of canvas will Dustin need is 7.5 square feet.

find the value of x in the figure
Answer:
70degrees
Step-by-step explanation:
Using the theorem;
Angle at the vertex is the half of the difference of the angles at its intercepted arcs
Angle at the vertex = 24 degrees
difference of the angles at its intercepted arcs = 118 - x
According to the theorem;
24 = 1/2(118 - x)
Cross multiply
24 * 2 = 118 - x
48 = 118 - x
x = 118 - 48
x = 70degrees
Hence the value of x is 70degrees

Identify a point that is 2 units away from (12, -34). Your answer should be
an ordered pair. (x, y) *
Answer:
I don't know lol
Step-by-step explanation:
To figure out if an ordered pair is a solution to an equation, you could perform a test. Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.
substitute for x+2y=12 and x=y-12
PLEASE HELP !
Answer:
x = -4, y = 8
Step-by-step explanation:
y - 12 + 2y = 12
=> 3y = 24
=> y = 8
x = 8 - 12
=> x = -4
Answer:
x = -4
y = 8
Step-by-step explanation:
We can substitute:
=> (y - 12) + 2y = 12
=> 3y - 12 = 12
=> 3y = 12 + 12
=> 3y = 24
=> y = 24/3
=> y = 8
Now we can substitute 8 in for y, in any of the equation given to find x:
=> x = (8) - 12
=> x = -4
