Answer:
53 mm
Step-by-step explanation:
Perimeter is the sum of the lengths of all its sides.
Let the length of the unknown side be x mm.
123= 25 +45 +x
x= 123 -25 -45
x= 53
Thus, the unknown side is 53 mm.

Answer:
d) ordered pairs are equal
e) ordered pairs are not equal
Step-by-step explanation:
d) ( 3+4 , 2 - 1)
x-co ordinate = 3 + 4= 7
y-co ordinate = 2 - 1 = 3
(3+ 4 , 2-1) = (7 , 3)

4t = 40
10 + t = 14
70 - t = 30
multiple answers , 40, 10 , 4
Answer:
1. t=102. t=43. t=40Step-by-step explanation:
Isolate the term of t from one side of the equation.
1. 4t=40First, you have to divide by 4 from both sides.
4t/4=40/4
Solve.
Divide the numbers from left to right.
40/4=10
t=102. 10+t=14First, change sides.
t+10=14
Then, subtract by 10 from both sides.
t+10-10=14-10
Solve.
Subtract the numbers from left to right.
14-10=4
t=43. 70-t=30First, subtract by 70 from both sides.
70-t-70=30-70
Solve.
30-70=-40
Rewrite the problem down.
-t=-40
Divide by -1 from both sides.
-t/-1=-40/-1
Solve.
Divide the numbers from left to right.
-40/-1=40
t=40Therefore, the correct answer is t=10, t=4, and t=40.I hope this helps! Let me know if you have any questions.
Answer:
4t =40 t= 10 4x10=40
10 + t = 14 t=4 10 + 4 = 14
70 - t =30 t= 40 70 - 40 = 30

How to determine the area of a piece of land in scientific notationfrom the question, we have the following parameters that can be used in our computation:
Area = 4,951,000 square meters
To write the area in square meters in scientific notation, we have
Area = 4.95 * 1,000,000 square meters
So, we have
Area = 4.95 * 10⁶ square meters
Hence, the area is 4.95 * 10⁶ square meters

Answer:
So the whole thing is 180, we already have 3x+12, it's C.
Because A would be 3x +180 (1803x) +something else which would bring it over 180.
Step-by-step explanation:
C is the answer because 180 is the toal and it isn't going over 180 right away.
Answer:
C. (3x +12) + x = 180°
Step-by-step explanation:
(3z+12)° is obtuse. x° is acute.
Both are supplementary angles that are linear pair that add up to 180°
(3x + 12)° + x° = 180°
4x + 12 = 180°
4x = 168°
x = 42°
Plug x into (3x + 12)°
3*42° + 12
126 + 12
138°

AAAAA single Cupcake can cost at most $5.
Step-by-step explanation:
Solve for x. The triangles in each pair are similar.
Step-by-step explanation:
similar triangles means that all angles in one triangle are exactly the same as the angles in the other triangle.
and the lengths of all sides of one triangle have the same scaling factor with the lengths of the sides of the other triangle.
so, when we compare the "features" of the triangles, we see that C corresponds to S, B to R and D to T.
so, DC (50) corresponds to TS (70).
and that means that CB (60) corresponds to SR (11x - 4).
the scaling factor from BCD to RST is 70/50 = 7/5.
that means DC × 7/5 = TS.
and CB × 7/5 = SR :
60 × 7/5 = 11x - 4
12 × 7 = 11x - 4
84 = 11x - 4
88 = 11x
x = 8

Linear is basically a straight line. It can be increasing or decreasing.
Decreasing is when on the graph, when x increases, y decreases.
On the graph, there are two parts that are decreasing. Between -2 and 0, and Between 2 and 4. Let's look at these two.
- For between -2 and 0, the line is not straight. Therefore, it is decreasing and nonlinear. We can check if this is the right answer.
- For between 2 and 4, the line is decreasing. However, the line is straight, which means it is decreasing but linear.
Your final answer is B.

A rectangular prism has a base of 15 ft2 and a height of 9 ft. What is the volume of the rectangular prism?
Answer:
135 ft^3
Step-by-step explanation:
Volume of a rectangular prism is basically just width x height x depth. So the area of the base multiplied by the height. 15 x 9 = 135
Answer: 135 ft³
Step-by-step explanation:
Volume, when dealing with a rectangular prism, is L * W * H
-> L * W can simplify to the base, as it does in the problem given to us.
V = (L * W) * H
V = B * H
V = 15 * 9
V = 135 ft³
The rectangular prism has a volume of 135 ft³.
