The expression that shows how many inches tall Tess is t = i - 3.
What is an expression?Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both.
Addition, subtraction, multiplication, and division are all possible mathematical operations. As an illustration, the expression x + y has the terms x and y with an addition operator between them.
In this case, Tess is 3 inches shorter than Johnny. and Johnny is i inches tall. Since Tess is shorter, we will subtract.
Therefore, the expression will be:
t = i - 3
where t = Tess height.

Answer:
x = 21
Step-by-step explanation:
Given line a is parallel to line b we can form the following equation to find the value of x:
6x + 12 + 2x = 180 (because these are supplementary angles and their sum is equal to 180)
add like terms
8x + 12 = 180 subtract 12 from both sides
8x = 168 divide both sides by 8
x = 21

how do I solve. step by ptep please
2x - y + 4z = 33
x + 2y - 3z = -26
-5 x - 3y +5z = 23
After solving the system of equations using Gaussian elimination we get the values as x = 5 , y = -11 and z=3
Given we have the system of equations as follows:
2x - y + 4z = 33
x + 2y - 3z = -26
-5 x - 3y +5z = 23
Rewrite the system in matrix form and solve it by Gaussian elimination.
[ 2 -1 4 [ 33
1 2 -3 = -26
-5 -3 5 ] 23 ]
Now divide row 1 by row 2.
[ 1 -0.5 2 [ 16.5
1 2 -3 = -26
-5 -3 5 ] 23 ]
Now R₂ - 1R₁ → R₂

[ 1 -0.5 2 [ 16.5
0 2.5 -5 = -42.5
0 -5.5 15 ] 105.5 ]
Divide row 2 by 2.5.
[ 1 -0.5 2 [ 16.5
0 1 -2 = -17
0 -5.5 15 ] 105.5]
R₁+0.5R₂ → R₁
R₃ + 5.5R₂ → R₃
[ 1 0 1 [ 8
0 1 -2 = -17
0 0 4 ] 12 ]
Divide R₃ by 4
[ 1 0 1 [ 8
0 1 -2 = -17
0 0 1 ] 3 ]
Therefore, R₁-1R₃→R₁
R₂ + 2R₃ → R₂
[ 1 0 1 [ 5
0 1 0 = -11
0 0 1 ] 3 ]
therefore x = 5, y=-11 and z = 3.

If the width and length of the carton is doubled, and the height remains the same, how much milk will the carton now hold? (3)
The carton can hold 8402.7cm3 or 8.4 litres of milk now
What volume of milk can the carton hold now?Initially, the width and length of the carton are 8.88cm each.
Now, the width and length of the carton are doubled. That is:
The width and length are 2 x 8.88cm = 17.76 cm each
But the height remains the same: 26.64cm
Volume of the carton = width x length x height
= 17.76 x 17.76 x 26.64
= 8402.7 cm3 = 8.4 litres
Therefore, the quantity of milk the carton can hold now is 8402.7 cm3 or 8.4 litres.

Between 11 pm and 8:10 am, the water level in a seimming pool decreased by 5/12 in. Assuming that the water level decreased at a constant rate, how much did the water level drop each hour?
The rate at which the water level dropped each hour is 5 / 34 inches per hour.
What is the rate of water drop each hour?In order to determine the rate at which the water level dropped each hour , divide the total decrease in the water level by the total time it took for the water to decrease.
Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations.
Change in water level per hour = total decrease / change in time
Change in time = 11 - 8 : 10 = 2 : 50 am = 2 hours 5/6 minutes
Change in water level per hour = 5/12 ÷ 2 5/6

The function that best describes the graph is y = x² + 9x + 18. The correct option is B. y = x² + 9x + 18
From the question, we are to determine the function that best describes the graph
From the graph, we can observe that the roots of the quadratic equation are x = -6 and x = -3
Thus,
(x + 6) and (x + 3) are factors of the quadratic equation.
Then,
Multiplying the factors, we get
(x + 6)(x + 3) = 0
x(x +3) + 6(x + 3) = 0
x² + 3x + 6x + 18 = 0
x² + 9x + 18 = 0

The set of possible dimensions (length and width) of the field are {13.5, 10, 5.5, and 26}.
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
The perimeter of a rectangle = 2(L+W)
Where W is the width of the rectangle and L is the length of the rectangle
The perimeter = 2W+ L
37 = 2W + L
L = 37 - 2W
Hence,
area = W(37 - 2W)
143 = 37W - 2W²
-2W² + 37W - 143 = 0
W² - 18.5 W + 71.5 = 0
W = 13.5, 5.5
Take the value of W = 13.5
Then,
L = 37 - 2W
L = 37 - 2(13.5)
L = 10 meters
Take the value of W = 5.5
Then,
L = 37 - 2W
L = 37 - 2(5.5)
L = 26 meters

2) The relationship between ∠8 and ∠4 is that they are alternate exterior angles
3) The relationship between ∠2 and ∠3 is that they are supplementary angles.
How to identify corresponding angles?When it comes to congruent angles, we know that when two parallel lines are intersected by a third one, the angles that occupy the same relative position at each intersection are known to be corresponding angles to each other.
Now, in the first figure, we see that there are a total of eight angles and we also see that 2 parallel lines have been intersected by a third one. Thus, some of the angles will be congruent to others. In this case, we see that the relationship between ∠1 and ∠3 is that they are corresponding angles.
Now, in the second figure, we see that there are a total of eight angles and we also see that 2 parallel lines have been intersected by a third one.

how can you eliminate the fractions from the equation n/5+3/7=2 using just one operation?
Answer:
Multiplying both sides of the equation by 35 eliminates the fractions
Step-by-step explanation:
You want to know how to eliminate the fractions from the equation n/5+3/7=2.
Multiplication property of equalityThe multiplication property of equality allows you to multiply both sides of an equation by the same number without changing the value of the variable. To eliminate fractions, the number we choose can be the least common denominator of the fractions.
ApplicationFractions with denominators 5 and 7 will have a least common denominator of 5·7 = 35. Multiplying the equation by 35 gives ...
35(n/5 +3/7) = 35(2)
7n +15 = 70
