How do I solve x/10 +4 = 10
Answer:
14 and simplify to 4
Step-by-step explanation:
Add 1010 to both sides.
x=4+10
x=4+10
2 Simplify 4+104+10 to 1414.
x=14
x=14
x−10=4
1 Let x=14x=14.
14-10=4
14−10=4
2 Simplify 14-1014−10 to 44.
4=4
4=4
Answer:
x=60
Solve for x by simplying both sides of the equation,then isolate the variable.Im not sure if this help but i tried.

The question is about trigonometry solving two sides it is a right triangle hypotenuse is X left side is 20 bottom side is 21 i need to find X and what degrees is angle A and B and C is already 90 degrees please help!!
Answer:
x = 29
Angle A = 46.4°
Angle B = 43.6°
Step-by-step explanation:
Since it is a right angle triangle, we can find x from pythagoras theorem;
x = √(20² + 21²)
x = √(400 + 441)
x = √841
x = 29
Using trigonometric ratios we can find angles A and B.
Opposite is 20
Adjacent is 21
Thus; opp/adj = tan B
20/21 = tan B
B = tan^(-1) 0.9524
B = 43.6°
Sum of angles in a triangle is 180°. Thus;
A = 180 - (90 + 43.6)
A = 46.4°
In basketball, each shot made is worth 1, 2, or 3 points. Miles scored a total of 27 points in his most recent game. He made three 1-point shots
and four 3-point shots.
How many 2-point shots did he make?
Answer:6
Step-by-step explanation:
Subtract the three 1 point shots
Subtract the four 3 point shots
You are left with 12, and you split that in 2 because they're 2 point shots.

What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
Let 'y' be the output and 'x' be the input.
Given the rule "Divide by 4, then add 2." Complete the following table. Then the function is given as,
y = (x / 4) + 2
At x = 0, then we have
y = (0 / 4) + 2 = 2
At x = 2, then we have
y = (2 / 4) + 2 = 3/2
At x = 4, then we have
y = (4 / 4) + 2 = 3
At x = 0, then we have
y = (0 / 4) + 2 = 2
At x = 0, then we have
y = (0 / 4) + 2 = 2
At x = 6, then we have
y = (6 / 4) + 2 = 5/2
At x = 8, then we have
y = (8 / 4) + 2 = 4
At x = 10, then we have
y = (10 / 4) + 2 = 7/2

y = x + 4
y = x - 4
does this system have a solution?
Answer:
No solution
Step-by-step explanation:
y = x + 4
y = x - 4
The slopes are the same (1), but the y intercepts are different ( 4, -4)
That means the lines are parallel, so they will not intersect. That means the system does not have a solution.
find the measure of the exterior angle
Answer:
132
Step-by-step explanation:
so all the angles of a triangles add up to equal 180 so to find the missing angle of the triangles we do 180-86-46 which equals 48. x is supplementary to the angles that equals 48 meaning that they will add up to equal 180. 180-48 = 132 so x =132
Find the value of x.
Answer:
x = 25
Step-by-step explanation:
it's an isosceles triangle so base angles are the same
3x - 30 = 45
Add 30 on both sides
3x = 75
divide both sides by 3
x = 25

During a game, Dennis lost 50 points in the first round and then lost 75 more points in the second round. Write an addition expression for the
change in Dennis's score after two rounds, and then find the change.
Enter the correct answers in the boxes.
Help
Answer:
-125
Step-by-step explanation:
add 50 and 75 =125 make in negative
The additional expression for the change in Dennis's score after two rounds is (-50) + (-75) and the value of change is -125.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that:
During a game, Dennis lost 50 points in the first round and then lost 75 more points in the second round.
Let x be the change in the points:
The points are 50 and 65
The expression can be written as:
= (-50) + (-75)
= -125
The negative sign needs to write before the numbers because Dennis lost 50 points and 75 points in the game.
Thus, the additional expression for the change in Dennis's score after two rounds is (-50) + (-75) and the value of change is -125.

Which two ratios represent quantities that are proportional?
Answer:
D. 45/18 = 35/14Step-by-step explanation:
Lets simplify the ratios where possible and compare:
A. 3/4 = 9/12 ≠ 5/12B. 32/20 = 16/10 ≠ 22/10C. 7/5 = 14/10 ≠ 14/9D. 45/18 = 5/2 (divide by 9) and 35/14 = 5/2 (divide by 7)The last two ratios represent proportional quantities
