Answer:
30m +50 = 20m +100m = 5yes. symmetric property of equality.Step-by-step explanation:
1. The expression for c in the first equation is (30m+50). Substituting that for c in the equation ...
c = 20m +100
gives you ...
30m +50 = 20m +100
__
2. Adding -50-20m to both sides gives ...
10m = 50
m = 5 . . . . . . . divide by 10
__
3. Doing the substitution in reverse, you would substitute (20m+100) for c in the equation ...
c = 30m +50
to get ...
20m +100 = 30m +50
This is the equation of part 1 with the expressions swapped to the other side of the equal sign. The symmetric property of equality tells you that changing sides of the equal sign does not change the value of the variable(s).
You get the same solution.
Add (5x3+7x−8)+(2x3−5x2−x+3).
A triangle with no sides congruent and all angles less than 90° is called a __________ triangle.
equiangular equilateral
acute right
acute scalene
acute isosceles
Answer:
acute scalene
Step-by-step explanation:
Hope it helps you in your learning process.
The triangle with no sides congruent and all angles less than 90° is called an acute scalene triangle option (C) is correct.
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
We have a statement:
A triangle with no sides congruent and all angles less than 90° is called a __________ triangle.
As we know, an acute scalene triangle is a triangle with no congruent sides and all angles smaller than 90 degrees.
Also,
A scalene triangle is one in which each side has a different measure.An isosceles triangle is one in which all sides are equal.An equilateral triangle is one in which all of its sides are equal.Thus, the triangle with no sides congruent and all angles less than 90° is called an acute scalene triangle option (C) is correct.

Please help me answer this question!
A population of 6000 bacteria is growing at a rate of 6% each day. Write 2 an equation that expresses the number of bacteria at time x.
A. y = 6000(.06)×
B. y = 6000(1.06)×
C. y = 6000(.94)×
Answer: B. y = 6000(1.06)×
Step-by-step explanation: If it is growing at six percent (0.06) each day then you must also account for the amount that is already there (1).

Which of those points does not lie on the line y = 3x + 5*
(1 Point)
O (1,8)
O (4, 17)
O (-2, 11)
0 (0,5)
Answer:
point (-2,11) does not lie on the given line
Step-by-step explanation:
To find : Which of the following points does not lie on the line ?
Solution :
To determine the point lie on line or not we have to put points in equation if it satisfy then it lie otherwise not.
a) Point (1,8)
Line y=3x+5
Substitute x=1 and y=8
8=3(1)+5
8=8
(1,8) point lie on the line.
b) Point (4,12)
Line y=3x+5
Substitute x=4 and y=17,
17=3(4)+5
17=12+5
17=17
(4,17) point does not lie on the line.
c) point (-2,11)
Line y=3x+5
substitute x=-2 and y=11
11=3(-2)+5
11=-6+5
11 is not equal to -1
d) Point(0.5)
Line y=3x+5
Substitute x=0 and y=5
5=3(0)+5
5=5

Answer:
60
Step-by-step explanation:
ez
Answer:
60
Step-by-step explanation:
to find the area of a trapezoid you do (a+b)/2 x h
so to find the area of yours you do (18+6)/2 x h
18 + 6 = 24
24 divided by 2 = 12
12 x 5 = 60
Find x, the missing side length in the right triangle 18 8
Answer:
19.7
Step-by-step explanation:

Answer:
65°
Step-by-step explanation:
Properties of a triangle:
Triangles always have 3 sidesThe sum of the interior angles of a triangle must be equal to 180°.To solve:
Since the angles inside of a triangle must always be equal to 180, use the following formula to solve:a + b + c = 180(The variables can be assigned to any value in this situation)Since two angles are already given, replace 2 variables:a + 85 + 30 = 180Solve the equation by subtracting on both sides:a = 65The value of a is the measure of the missing angle. The problem is solved.Answer:
the missing angle is 65
Step-by-step explanation:
a whole triangle is 180
subtract the given angles from 180
180
- 85
----------
95
subtract the remaining angle
95
- 30
---------
65

According to the US Census, the percent of residents aged 65 or older in the 50
states and District of Columbia has mean 13.26% and standard deviation of
1.67%. Find and interpret the standardized scoreſfor the state of Colorado, which
had 9.7% of residents age 65 or older. *
Answer:
z = -2.13
Therefore, the standardized z score for the state of Colorado means the score is below the mean.
Step-by-step explanation:
The formula for z score is given as:
z = (x-μ)/σ,
where
x is the raw score = 9.7%
μ is the population mean = 13.26%
σ is the population standard deviation = 1.67%
z = z score or standardize score
Hence,
z = 9.7 - 13.26/1.67
z = -2.13174
Approximately z = -2.13
Therefore, the standardized z score for the state of Colorado means the score is below the mean
