Answer:
x=8
this is because you do 57+89=146
and then you do 180-146 because a triangle adds up to 180.
this gives you 34
so the value of 5x-6=34
add the 6 onto 34 which gets rid of the -6 ans fives you the answer of 40
After that yoy divide 40 by 5 which gives you the value of x which is 8
Write the expression 4 divided by the sum of X and 7
Answer:
4/(x + 7)
Step-by-step explanation:
4 is being divided by x + 7 here. You can't combine x and 7 because they're not like terms.
In the figure, 'O' is the centre of the circle, ZABO= 20°and ZACO= 30°, where
A, B, C are points on the circle. What is the value of x ?
120
Given:
Consider the below figure attached with this question.
[tex]\angle ABO=20^\circ[/tex]
[tex]\angle ACO=30^\circ[/tex]
To find:
The value of x.
Solution:
Draw a line segment OA as shown below.
In triangle ABO,
[tex]OA=OB[/tex] [Radii of same circle]
[tex]m\angle BAO=m\angle ABO=20^\circ[/tex] [Base angles of an isosceles triangle]
In triangle ACO,
[tex]OA=OC[/tex] [Radii of same circle]
[tex]m\angle CAO=m\angle ACO=30^\circ[/tex] [Base angles of an isosceles triangle]
Now,
[tex]m\angle BAC=m\angle BAO+m\angle CAO[/tex]
[tex]m\angle BAC=20^\circ+30^\circ[/tex]
[tex]m\angle BAC=50^\circ[/tex]
Central angle is always twice of angle subtended by two points on the circle.
[tex]m\angle BOC=2\times m\angle BAC[/tex]
[tex]x=2\times (50^\circ)[/tex]
[tex]x=100^\circ[/tex]
Therefore, the value of x is 100°.
John borrowed $20,000 from Beth. He pays $500 per month in interest. What is the percentage interest rate?
Answer: 2.5%
Step-by-step explanation:
From the question, we are informed that John borrowed $20,000 from Beth and that he pays $500 per month in interest.
The percentage interest rate would be calculated thus:
= Amount paid as interest / Amount borrowed × 100
= 500/20000 × 100
= 2.5%

Answer:
72°
Step-by-step explanation:
So the three angles of a triangle always add up to 180°. This means that
[tex]15x + 21x + 24x = 180[/tex]
This becomes:
[tex]60x = 180[/tex]
And solves as:
[tex]x = 3[/tex]
The largest angle has to be the one marked with 24x because it has the largest coefficient and x is a constant.
[tex]24x = 24(3) = 72[/tex]
The measure of the largest angle in the triangle is 72°.
72 degrees is the biggest angle in the given triangle.
What are the properties of the triangle?The properties of the triangle are: The sum of all the angles of a triangle (of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.
Given that the three angles of the triangle are 24x, 21x, and 15x
Since the sum of all the angles of the triangle is always 180 degrees
Thus,
24x +21x + 15x = 180
60x = 180
x = 3
Thus, the biggest angle would be 24x
biggest angle of triangle = 24 * 3 = 72
Therefore, the biggest angle of the given triangle is 72 degrees

i just need y intercept and equation
Answer:
Slope = 4y-intercept = -8Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slope b is the y-interceptGiven the table
x y
2 0
7 20
Determining the slope between (2, 0) and (7, 20)
(x₁, y₁) = (2, 0)
(x₂, y₂) = (7, 20)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [20 - 0] / [7 - 2]
= 20 / 5
= 4
Thus, the slope of the line = m = 4
now substituting the point (2, 0) and the slope m = 4 in the slope-intercept form of a line equation to determine the y-intercept b.
[tex]y = mx+b[/tex]
0 = 4(2) + b
b + 8 = 0
subtract 8 from both sides
b + 8 - 8 = 0 - 8
b = -8
Thus, the y-intercept = -8
Summary:
Slope = 4y-intercept = -8What is 10 to the 3rd power x n = 690

A decorative fence surrounds a rectangular flower garden that is 2 yards long and 3 yards wide. The area of the garden is increased by 20 % . If the width remains the same, what is the new length of the garden?
Answer:
30
dfdfg
Step-by-step explanation:gfdgdfg
The area of the garden is increased by 20 % . If the width remains the same, then the new length of the garden is 2.4 yards.
What is Area of Rectangle?The area of Rectangle is length times of width.
Given that A decorative fence surrounds a rectangular flower garden that is 2 yards long and 3 yards wide
Area = Length × Width
Area=6 yards.
The area of the garden is increased by 20 % .
20/100=0.2
the area would equal 6 (l x w) and 6 increased by 20% equals 7.2.
As the width remains same
so we use 7.2/3 to find the new length
7.2/3=2.4 yards.
Hence, 2.4 yards is the new length of the garden.

For homework plss help
Answer:
B, C, D and E are correct options
Step-by-step explanation:
Here, we want to get the correct options;
a. We simply divide the next term by the previous term so that we get the common ratio
That would be 16/-8 = -32/16 = -2
As we can see, the common ratio is -2 which means that the option cannot be correct
b. The 5th term is mathematically;
ar^4 = -8 * (-2)^4 = -8 * 16 = -128
This is correct
c. The 7th term is
ar^6 = -8 * (-2)^6 = -512
5th term is ar^4 = -8 * (-2)^4 = -128
So -512/-128 = 4
As we can see, this option is correct
d. 8th term is 1024
8th term is ar^7
= -8 * (-2)^7 = 1024 which is correct
e. 10th term is ar^9 = -8 * (-2)^9 = 4096
9th term is ar^8 = -8 * (-2)^8 = -2048
