slove using elimination10x + 8 y = 20 10 x + 2 y = -10
Answers
we have
10x + 8 y = 20 ------> equation A
10 x + 2 y = -10 ------> equation B
Multiply equation A by -1 both sides
so
-10x-8y=-20 -----> new equation A
Adds new equation A and equation B
\
--------------------
-8y+2y=-20-10
-6y=-30
y=5
Find the value of x
substitute the value of y in equation A or equation B or new equation A
10x + 8(5) = 20
10x+40=20
10x=20-40

One Serving of pancakes takes 2/3 cups of milk how many cups of milk with 24 servings for pancakes required
Answers
Answer:
Step-by-step explanation:
Given that:-
Since, Serving of 1 pancakes takes 2/3 cups of milk
Hence, serving of 24 pancakes takes (2/3)*24
=48/3
=16
So that; 16 cups of milk are required for serving of 24 pancakes.
Answer:
16 cups of milk
Step-by-step explanation:
Make a proportion
[tex]\frac{serrvings}{cups of milk}[/tex] = [tex]\frac{servings }{cups of milk}[/tex]
[tex]\frac{1}{\frac{2}{3} }[/tex] = [tex]\frac{24}{x}[/tex] cross multiply and solve
1x = [tex]\frac{2}{3}[/tex][tex](\frac{24}{1})[/tex] 1x is the same a x. 24 is the same as [tex]\frac{24}{1}[/tex]
x = [tex]\frac{48}{3}[/tex]
x = 16

The numerator of a rational number is 4 less than its denominator. If I is added to both its numerator and denominator, it becomes 2/3 Find the rational number.
Answers
The required rational number is 7/11.
let the denominator be x.
and since we are given that the numerator of a rational number is 4 less than its denominator, the numerator will be x-4.
working on the given condition, i.e. If I is added to both its numerator and denominator, it becomes 2/3
(x-4+1)/(x+1) = 2/3
further solving it by cross multiplication we get,
3(x-4+1)=2(x+1)
=> 3(x-3)=2x+2
=> 3x-9=2x+2
=> 3x-2x=9+2
=> x=11
=> x= 11 (denominator)
we know the numerator is 4 less than the denominator i.e.
11-4=7
thus the required fraction will be 7/11.

a ferry charges $40 for each car and $8.50 for each person in the car. Does this situation represent a function?
Answers
Yes, This situation represent a function.
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
The cost of each car = $40
The cost of each person = $8.50
Let the number of car = x
The number of persons in a car = z
Then, Total cost of car = $40x
Total cost of persons in car = $8.50z
So, Total cost (y) = $40x + $8.50z
Thus, The function for this situation is;
y = $40x $8.50z
Clearly, This is a linear function with three variable.
Thus, This situation represent a function.

5.Given the functions f(x)=-2x + 4 and g(x) = 2x- 8, find the value of x for which f(x) = g(x).
6.Graph the function.
Answers
By graphing both equations and finding where the graphs intercept, we can see that the solution for the system is x = 3.
For which value of x both functions give the same output?Here we have the functions:
f(x) = -2x +4
g(x) = 2x - 8
We want to find the value of x such that:
f(x) = g(x).
If we graph the two functions, we just need to identify the x-value of the point where the functions intercept.
The graph can be seen in the image below.
There we can see that the graphs intercept at (3, -2), meaning that the solution of:
f(x) = g(x) is x = 3.
Which is the same thing that if we write:
f(x) = g(x)
-2x + 4 = 2x - 8
4x = 12
x = 12/4 = 3
x = 3

The water pressure on a submerged object is given by P = 64d, where P is the pressure in pounds per square foot, and d is the depth of the object in feet.
a. solve the formula for d.
b. Find the depth of a submerged object if the pressure is 672 pounds per square foot.
Answers
a. Solving for 'd' as the subject of formula gives d = P/64
b. The depth of a submerged object if the pressure is 672 pounds per square foot is 10. 5 feet
What is a function?A function can be defined as an expression, law or rule that shows the relationship between two variables.
These variables are namely;
Independent variableDependent variableGiven the function as;
P = 64d
Where;
P is the pressure in pounds per square foot d is the depth of the object in feetNow, let's make the variable 'd' the subject of formula
Divide both sides of the equation with the coefficient of the variable 'd' which is 64. This is done so that the variable stands alone.
We have;
P/64 = 64d/64
d = P/ 64
If the pressure, P equals 672 pounds per square foot
Substitute the value of the variable into the formula, we have;
d = P/64
Then,
d = 672/64
Find the quotient
d = 10. 5 feet.
Thus, the value is 10. 5 feet

The median of a set of numbers is the number that appears in the middle after arranging the set of numbers in ascending or descending order
Step 1:Arrange the given values in ascending order.
Step 2. Find the number of observations in the given set of data. It is denoted by n.
Step 3. If n is odd, the median equals the [(n+1)/2]th observation.
The set of numbers given in the question are

Answers
The time taken for the bomb to fall to the ground is 2.5 sec.
What is a projectile motion?In this case, the bomb is moving like a projectile and has projectile motion.A body can only move in a projectile motion when it is affected by gravity. A body moving as a projectile is a projectile motion.We model a particle as having zero acceleration (and thus constant velocity) when it is projected horizontally.The particle in this instance has a zero initial velocity and a constant downward vertical acceleration of g.Given:
Height (h) = 50 m
Horizontal velocity(u) = 20 m/s
Time (t) =?
We use, h = ut to determine the time
50 = 20 × t
Divide both sides by 20,
t = 50 / 20
t = 5/2 s ≅ 2.5 sec
Thus, the bomb will take 2.5 sec to land on the ground.
