Answer:
-2.1
Step-by-step explanation:
x= 4/5
you put in 4/5 where x is supposed to be so you get: -2/5 - 4/5 + (-9/10)
-2/5 - 4-5 = -6/5
-6/5= -12/10
-12/10 + -9/10= -21/10 = -2.1

Answers
Answer:
87=x + 4 x=83
Step-by-step explanation:
87= x + 4
Switch sides
x + 4 = 87
Subtract 4 from both sides
x + 4-4 = 87-4
Simplify
x = 83

[tex]5\sqrt{3}[/tex]
Step-by-step explanation:
A triangle with angles of 30-60-90 will always have sides that measure in the following proportions:
The side opposite the 30* angle = a
The side opposite the 60* angle = [tex]a\sqrt{3}[/tex]
The side opposite the 90* angle = 2a
(I used "a" here because your question uses "x" and I don't want to confuse things, but usually people use "x" rather than "a")
They gave us that the hypotenuse (the side opposite the 90* angle) is 10, from there we can figure out the other sides:
Since the side opposite 90* is 2a, and 2a = 10, divide 10 by 2 and you get a = 5.
Once we know what "a" is, we can fill in the rest:
30* = 5
60* = [tex]5\sqrt{3}[/tex]
90* = 10

A movie starts at 7:10 and ends at 9:03. How long does the movie last?
Answers
Answer:
1 hour and 53 minutes
Step-by-step explanation:
Let's start at 7:10.
7:10 - 8:10 is 1 hour.
8:10 - 9:00 is 50 more minutes.
Total so far is 1 hour 50 minutes.
9:00 - 9:03 is 3 more minutes.
Total would be 1 hour and 53 minutes
Hope this answer helped! :)
Answer:
1 hour and 53 minutes
Step-by-step explanation:
You just need to subtract the times form each other.
There are two ways to do this.
Subtract the number of minutes and convert into total hours and remainder minutes.
Or you can just do the simple way shown by the answer above.
I will show the subtracting minutes one since it can be a base for all .
First we find how many minutes are in 7 hours and 10 minutes, and nine hours and three minutes.
7 hours and ten minutes is 430 minutes. 9 hours and 3 minutes is 543 minutes.
543 - 430 is 113.
Then you divide, we are using the remainder type division.
113/60(60 minutes in one hour)
60 goes into 113 one time and leaves 53.
Therefore, it takes 1 hour and 53 minutes.

Use the table to write a linear function that relates y to x.
Answers
Answer:
y=(3/2)x+5
Step-by-step explanation:
Sketch it out real quick on a piece of paper.
As you can tell from the table, for every 3 units along the x axis, 2 units upwards are taken along the y axis.
This makes the slope of the equation (3/2)x or (1 1/2)x
The y-intercept is at y=5 because (on the table), when x=0, y=5.
This makes the equation in point-slope form y=(3/2)x+5
Find the value of x.

A choir teacher is dividing 12 sopranos and 9 altos into singing groups. He wants each group to have the same combination of sopranos and altos, with no singers left over. What is the greatest number of groups he can make?
Answers
Answer:
3 groups
Step-by-step explanation:
Sopranos = 12
Altos = 9
Find the highest common factor of 12 and 9
12 = 1, 2, 3, 4, 6, 12
9 = 1, 3, 9
The highest common factor of 12 and 9 is 3
Therefore, the choir teacher can only have 3 groups
12 sopranos / 3 groups
= 4 sopranos per group
9 Altos / 3 groups
= 3 altos per group
Each of the 3 groups Will have 4 sopranos and 3 altos each

Given:
A quadrilateral inscribed in a circle.
To find:
The value of x and y.
Solution:
If a quadrilateral inscribed in a circle, then it is known as cyclic quadrilateral and the opposite angles of a cyclic quadrilateral are supplementary angles, it means their sum is 180 degrees.
[tex]5x^\circ+110^\circ=180^\circ[/tex] [Supplementary angles]
[tex]5x^\circ=180^\circ -110^\circ[/tex]
[tex]x^\circ=\dfrac{70^\circ}{5}[/tex]
[tex]x^\circ=14^\circ[/tex]
The value of x is 14 degrees.
[tex]2y^\circ+104^\circ=180^\circ[/tex] [Supplementary angles]
[tex]2y^\circ=180^\circ -104^\circ[/tex]
[tex]y^\circ=\dfrac{76^\circ}{2}[/tex]
[tex]y^\circ=38^\circ[/tex]
Therefore, the value of x is 14 degrees and the value of y is 38 degrees.
