What is an expression in two variable?An expression in two variables is a combination of numbers and two variables using mathematical operation +,-,/,*. It will a linear expression when the maximum power of variables is only one in the expression.
Let x and y are two variables and a, b, c are some numbers. Then a linear two expression can be given by ax+ by+ c
Given the cost of one scoop sundae is 2.75 and a cost of a two scoop sundae is 4.25
Let the number of sundaes of one scoop sundae be x and the numbers of sundaes be y
Then the total cost of these sundaes is given as by expression 2.75x + 4.25y
Given that there are 3 one scoop sundaes and 2 two scoop sundaes
Thus, x= 3 and y = 2
Total cost is given by expression= 2.75(3)+ 4.25(2)= 16.75
Therefore, he total cost of 3 one scoop sundaes and 2 two scoop sundaes is 16.75

describe a real-world situation where you can apply finding the unit rate
A real-world situation where you can apply the unit rate is finding the cost of a single can of soda from a pack of soda.
How can you use the unit rate?The unit rate refers to the price of a single item out of a number or group of items. It is found by dividing the total price of the group of items by the number of items in the group.
In a real-world scenario, you might see a pack of soda priced at $5.20 and you need to know the price of a single can of soda. You can find this by the formula:
= Price of soda pack / Number of soda cans
= 5.20 / 6
= $0.87

Answer: x=26 degrees
Step-by-step explanation:
90+x+64=180 ==> A right angle, x, and 64 lie on a straight line. Straight lines add up to 180 degrees and are called straight angles. Right angles are denoted with a tiny square inside them and measure 90 degrees.

Find the unique solution to this system of equations. Give your answer as a point. (x, y, z)
The point (x,y,z) = (₋1,3,₋1) is the solution of the equations.
Given the system of equations are:
2x ₊ y ₊ 3z = ₋2 .....eq(1)
x ₋ y ₋ z = ₋3 ...... eq(2)
3x ₋ 2y ₊ 3z = ₋ 12 .... eq(3)
Solving equation 1 and 2.
2x ₊ y ₊ 3z = ₋2
x ₋ y ₋ z = ₋3
Multiply eq(1) by 1 and eq(2) by 2, we get:
2x ₊ y ₊ 3z = ₋2
2x ₋ 2y ₋ 2z = ₋6
⁻ ⁺ ⁺ ⁺
hence sign changes, then we get:
3y ₊ 5z = 4 ... eq(a)
now solving equation 2 and 3.
x ₋ y ₋ z = ₋3
3x ₋ 2y ₊ 3z = ₋ 12
Multiply eq (2) by 3 and eq (3) by 1.
₋3x ₊ 3y ₊ 3z = 9
3x ₋ 2y ₊ 3z = ₋ 12
sign changes, and we get:
y ₊ 6z = ₋3 ..... eq(b)
y = ₋3 ₋ 6z
substitute y value in eq(a)
3(₋3₋6z) ₊ 5z = 4
₋9 ₋ 18z ₊ 5z = 4
₋13z = 13
z = ₋1
substitute z value in eq(b)
y ₊ 6(₋1) = ₋3
y ₋ 6 = ₋3
y = 3
substitute y and z values in eq (2)
x ₋ (3) ₋ (₋1) = ₋3
x ₋ 3 ₊ 1 = ₋3
x ₋ 2 = ₋3
x = ₋3 ₊ 2
x = ₋1

Even though scientists can't directly observe what is happening on Mars, they can send satellites to orbit Mars which can document the various aspects of Mars and its geography.
How can we observe Mars?Thanks to massive strides in space technology, humans have been able to study Mars all the way from Earth without having to observe the planet directly.
The main way they can do this is by positioning satellites around Mars which will orbit the planet. These satellites will record and observe things such as the composition of the atmosphere of Mars and how its terrain works.

The constant of variation is 72.
Constant of Variation: What is it?In a direct variation, the constant of variation is the constant (unchanged) ratio of the two variables. The formula for direct variation is. where k is the variational constant and y=kx (or y=kx).
being that
x = 8
y = 9
If x varies in opposition to y, then
x*y = fixed
which means
x*y = k (where we assume constant as k) (where we take constant as k)
Inputting the values of x and y now yields,
8*9 = k

Ken invested $10,000 in two bank accounts. One of the accounts pays 4% annual interest, and the
other account pays 6% annual interest. If the combined interest earned in both accounts after a
year was $514, how much money was invested in each account?
Ken invested $5,700 in the 6% account, and the other $4,300 in the 4% account.
How much money was invested in each account?Let's define the variables:
x = amount of money on the 4% account.y = amount of money on the 6% account.We know that Ken invested $10,000 in total, so:
x + y = 10,000
And the interest in one year is:
x*0.04 + y*0.06 = 514
Then we have a system of equations:
x + y = 10,000
x*0.04 + y*0.06 = 514
To solve it we start by isolating one of the variables in one of the equations, isolating x we will get:
x = 10,000 - y
Replacing that in the other equation we get:
(10,000 - y)*0.04 + y*0.06 = 514
400 - y*0.04 + y*0.06 = 514
400 + y*0.02 = 514
y = (514 - 400)/0.02 = 5,700
Then Ken invested $5,700 in the 6% account, and the other $4,300 in the 4% account.

The graph which does not represent y as a function of x is (B) as a line drawn can't touch the graph at two points.
The function that dose not show y as a function of x.
Y is a function of X, means that a certain variable magnitude or phenomenon Y is determined/caused by another magnitude or phenomenon X, such that the behavior of X will affect that of Y. In logic, a function symbol is a logical symbol that may be applied to an object term to produce another object term.
If a vertical line is drawn such that it touches more than one place, then it is not a function of x.

Step-by-step explanation:
Given 6 1/8 yards of ribbon, you want the leftover amount after making 4 bows that use 13/16 yards each.
Quantity usedIf each of 4 bows takes 13/16 yards, the amount required for bows is ...
4×13/16 = 13/4 . . . . yards
Quantity remainingThe amount left over is the difference between the starting amount and the amount used:
6 1/8 - 13/4 = 49/8 -26/8 = 23/8 = 2 7/8
The hairdresser has 2 7/8 yards of ribbon remaining.
