-9/24+4/24=-5/24
Answer:
-3
Step-by-step explanation:
multiply to make it a common number so -3/8 times 6/6 and 1/6 times 8/8
so -18/48 times 8/48. Then you multiply the top numbers to get 144/48. Then you simplify or divide so -3.

how to turn a mixer number to a improper fraction
Step-by-step explanation:
1. keep the demoninator the same
2. to find the numberator, multiply the demoninator number by the whole number, and add the product of that with the numerator number.
example:
2 3/8 = 19/8
1. so, keep the denominator the same, which means that the denominator is 8
2. to find the numerator, you do:
8 times 2 = 16
16 + 3 = 19
--
therefore, the improper fraction of 2 3/8 is 19/8

He must sell more than 12 hats. \ a) Write the system of inequalities that model this situation. Let x represent how many shirts he sells and y represent how many hats he sells.
Answer:
10x + 8y = $200
Where y > 12
Step-by-step explanation:
Let x represent how many shirts he sells
y represent how many hats he sells.
John is doing a fundraiser for school. He needs to sell at least $200 worth of items. John is selling shirts for $10 each and hats for $8 each.
He must sell more than 12 hats.
y > 12

Eric started at sea level. He descended 13.7 meters and then ascended 15.2 meters. Write an additional expression in the form Descent + Ascent to represent this situation. Then calculate the sum and explain what it represents.
An additional expression in the form Descent + Ascent to represent this situation is -13.7 + 15.2. The sum will be 1.5 meters.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Eric started at sea level. He descended 13.7 meters and then ascended 15.2 meters.
The expression will be written as,
E = -13.7 + 15.2.
E = 1.5 meters
Therefore, the additional expression in the form Descent + Ascent to represent this situation is -13.7 + 15.2. The sum will be 1.5 meters.

Answer:
∠A = 90
∠B = 30
∠C = 60
Step-by-step explanation:
Let ∠B = x
∠A = 3x
∠C = x + 30
Angle sum property of triangle: Sum of three angles of triangle is 180
x + 3x + x + 30 = 180 {Combine like terms}
5x + 30 = 180
5x = 180 - 30
5x = 150
x = 130/5
x = 30
∠A = 3*30 = 90
∠C = 30 + 30 = 60
16.Which Three Lengths CANNOT be the lengths of the sides of a triangle?
17.Which Three Lengths COULD-BE the lengths of the sides of a triangle?
Problem 16
Answer: Choice B) 21, 8, 10This is because the two smaller sides 8 and 10 add to 8+10 = 18, but this is not greater than the side 21. For a triangle to be possible, the sum of any two sides must be larger than the third side. I recommend cutting out slips of paper of these lengths to confirm that a triangle is indeed not possible in this case.
=====================================================
Problem 17
Answer: Choice B) 10, 15, 22Choice A is not the answer because 13+8 = 21, but that's not larger than the third side 21.
Choice C is not the answer because 6+11 = 17 which is not larger than 24.
Choice B is the only possible answer. Note we have the three following true inequalities
15+22 > 1010+22 > 1510+15 > 22So adding any two sides of this triangle leads to a sum larger than the third side. We're using the triangle inequality theorem.

Math homework was due 7 times total; how many total times was writing due? *

Answer:
10
Step-by-step explanation:
The answer is 10 because there are 20 days and no home work is due on 7 of those days so that’s 13 days with homework from math or writing. Then you take the three days where it was just math and subtract that to get 10 days of writing.

5) Solve for x,

8x -23
Answer:
8x + 128??
Step-by-step explanation:
Answer:
To start off, lets label this triangle ABC where A is the top right vertical, the top left verticle is B, and the bottom one is C. Now lets label the 2 points of intersection from the line segment 8x-23 D and E where the left intersection is E and the right is D.
Notice how CE and AE have an arc and that AC was split to get AE and CE. The 2 arcs show us that the intersection E is located at half the line segment.
This is the same on the other line segment BC. So if E and D are half of those line segments then the line segment ED must be half of the parallel segment above it. Because this is true, 2(8x-23)=10x+44
Now we have an equation and we can solve:
2(8x-23)=10x+44
16x-46=10x+44
6x-46=44
6x=90
x=15

Work out the area of a rectangle with base, b =
18mm and perimeter, P = 60mm.
b b
Answer:
Area of rectangle = 216 square mm
Step-by-step explanation:
Base (b ) = 18 mm
width = 'x' mm
Perimeter of rectangle = 2*(base + width)
Perimeter = 60 mm
2*(base + width) = 60 mm
2 *(18 + x ) = 60
2*18 + 2*x = 60
36 + 2x = 60
2x = 60 - 36
2x = 24
x = 24/2
x = 12
Width = 12 mm
Area of rectangle = base * width
= 18 * 12
= 216 square mm
Alain lanzó una piedra desde un puente al río de abajo.
La altura de la piedra (en metros sobre el agua) xxx segundos después de que Alain la lanzó está modelada por:
h(x)=-5x^2+10x+15h(x)=−5x
2
+10x+15h, left parenthesis, x, right parenthesis, equals, minus, 5, x, squared, plus, 10, x, plus, 15
¿Cuál es la altura de la piedra en el momento que la lanza?
Responder:
15m
Explicación paso a paso:
Dada la expresión de la altura de la pelota lanzada modelada por la ecuación;
h (x) = -5x² + 10x + 15
El momento en que se arrojó la piedra es cero, es decir, x = 0 segundos
Sustituya x = 0 en la ecuación y encuentre h (x) como se muestra;
h (x) = -5x² + 10x + 15
h (0) = -5 (0) ² + 10 (0) +15
h (0) = 0 + 0 + 15
h (0) = 15 m
De ahí que la altura de la piedra cuando la arrojes sea de 15 m
