Use the diagram of triangle MNO where, X, Y, and Z are the midpoints of the sides.
Answer:
YZ = 7 , MO = 8
Step-by-step explanation:
A segment joining the midpoints of 2 sides of a triangle is half the length of the third side.
(11)
YZ = [tex]\frac{1}{2}[/tex] MN , that is
3x + 1 = [tex]\frac{1}{2}[/tex] (10x - 6) = 5x - 3 ( subtract 5x from both sides )
- 2x + 1 = - 3 ( subtract 1 from both sides )
- 2x = - 4 ( divide both sides by - 2 )
x = 2
Then
YZ = 3x + 1 = 3(2) + 1 = 6 + 1 = 7
(12)
XY = [tex]\frac{1}{2}[/tex] MO , that is
x - 1 = [tex]\frac{1}{2}[/tex] (3x - 7) ← multiply through by 2 to clear the fraction
2x - 2 = 3x - 7 ( subtract 3x from both sides )
- x - 2 = - 7 ( add 2 to both sides )
- x = - 5 ( multiply both sides by - 1 )
x = 5
Then
MO = 3x - 7 = 3(5) - 7 = 15 - 7 = 8

A triangle has an area of 160 square inches and the base of the triangle is 40 inches. What is the height of the triangle?
Answer:
8 inches
Step-by-step explanation:
h = 2 A/b
A = 160
b = 40
160/40 = 4
2 x 4 = 8 inches
The height of the triangles is 8in.

Josh works in a balloon store he will put 45 balloons into bunches he must use the same number of balloons in each bunch the number of balloons in each bunch must be greater than one and less than 10 how many balloons could be in each bunch what I wrote was 357 balloons is that wrong or right?
Answer: 5 or 9
Find the factors of the number 45.
1, 5, 9, 15
The numbers must be greater than 1 and less than 10.
Now, we must take 5 and 9.
5 x 9 = 45
9 x 5 = 45
The answers are 5 & 9.

Find the slope of the line x=+6
Step-by-step explanation:
x = 6
is a straight vertical line (parallel to the y-axis, going through x=6 on the x-axis).
it's slope is therefore undefined (infinite). every possible y value (from -infinity to +infinity) is associated with this one x value (6).
The data for the distance d, in miles, remaining for a train to travel to its destination t hours after it departs a station are
shown in the scatter plot. Which of the following functions best fits the data?
Using the slope - intercept format, the equation which models the data represented by the graph is d(t) = -50t + 300
According to the general form of a linear regression equation :
y = bx + c b = slope ; c = interceptSlope, b = (Δy ÷ Δx)
Slope = (200 - 50) ÷ (2 - 5)
Slope = 150 ÷ -3 = -50
Intercept is the point where the regression line crosses the y - axis.
From the graph, the intercept = 300
Hence, the regression equation is y = -50t + 300

How to solve algebraic inequalities.
Algebraic inequalities can be solved in the same way in which algebraic equations are solved.
Find the 66th term of the arithmetic sequence -10, 7, 24, ...−10,7,24,...
Answer:
a(66) = -10 + 17(65) = 1095
Step-by-step explanation:
We know that this is an arithmetic sequence. Subtracting -10 from 7 results in 17; subtracting 7 from 24 also results in 17. Thus, the common difference, d, is 17. The first term is -10.
The general form of an arithmetic sequence is a(n) = a(1) + d(n - 1).
Substituting -10 for a(1) and 17 for d, we get:
a(n) = -10 + 17(n - 1)
Now let n = 66: a(66) = -10 + 17(66 - 1), or a(66) = -10 + 17(65) = 1095
The lines represented by the equations 5y - x = 5 and y - x = 1 are
Answer:
Same line
Step-by-step explanation:
5y - x = 5 y - 1/5x = 1
5y = x + 5 y = 1/5x + 1
5y/5 = x/5 + 5/5
y = 1/5x + 1
