Answer:
Step-by-step explanation:
I'm assuming that you are solving for x, since there's nothing else you can do with this mathematically.
[tex]\frac{1}{2}x=-9[/tex] and the goal is to get the x all alone. So we have to lose the fraction. Do that by multiplying by the reciprocal of 1/2 which is 2/1 (a reciprocal is just a fraction flipped upside down). BUT...because this is an equation, what you do to the left side has to be done to the right side too. Like this:
[tex](\frac{2}{1})\frac{1}{2}x=\frac{-9}{1}(\frac{2}{1})[/tex]
On the left, everything cancels out but the x (which is why we do this), and on the right we multiply straight across the top and straight across the bottom to get
[tex]x=\frac{-18}{1}[/tex] which is
x = -18

Joe has a bag of 24 pieces of candy. He gives 1/8 of them to a friend,
1/7 of what is left to another friend. How many pieces does he have
left?
Answer:
18 pieces.
Step-by-step explanation:
1/8 of 24 is 3.
24 - 3 = 21, that's how much he has left after giving it to the first friend.
1/7 of 21 is also 3.
21 - 3 = 18, there's your answer.
Answer:
18
Step-by-step explanation:
1/8 of 24 is 3 = 21
1/7 of 21 is 3 = 18

3 -4. Litros d jugo de frutilla 1 y 1-2 litro de jugo de manzana 1-8 litro de jugo de limón Y 1 y 1-2 litro de agua .Cuántos litros de jugo preparo la mamá??
Answer:
La madre hizo en total 2 y 3/8 litros de jugo.
Step-by-step explanation:
Sabemos que preparó:
3/4 litros de jugo de frutilla = 3/4 L
1 y 1/2 litro de jugo de manzana = (1 + 1/2) L
1/8 litro de jugo de limón = 1/8 L
1 y 1/2 litro de agua = (1 + 1/2) L
¿Cuántos litros de jugo preparó la mamá?
Simplemente debemos sumar los distintos volúmenes de jugo escritos arriba (el de agua no, pues solo nos pregunta cuantos litros de jugo se prepararon)
Total de jugo = 3/4 L + (1 + 1/2) L + 1/8 L
Para completar esta suma, separamos los números enteros de los racionales:
Total de jugo = 1 L + ( 3/4 + 1/2 + 1/8) L
Para resolver la suma dentro del paréntesis, debemos tener todos los números con el mismo denominador.
Recordar que si multiplicamos el numerador y el denominador por el mismo número, entonces el número racional no cambia.
Como el denominador más grande dentro del paréntesis es 8 (que tambien es multiplo de los otros dos), tratemos de reescribir los otros dos números de tal forma que su denominador también sea 8:
Total de jugo = 1 L + ( (2/2)*(3/4) +(4/4)*(1/2) + 1/8) L
= 1 L + (6/8 + 4/8 + 1/8) L
= 1 L + (11/8) L
podemos reescribir el segundo termino como:
= 1L + (8 + 3)/8 L
= 1L + (8/8) L + (3/8) L
= 1L + 1L + 3/8 L
= 2L + 3/8 L
La madre hizo en total 2 y 3/8 litros de jugo.

Answer:
PK = 75
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{PK}{WK}[/tex] = [tex]\frac{AK}{NK}[/tex] , substitute values
[tex]\frac{PK}{54}[/tex] = [tex]\frac{62.5}{45}[/tex] ( cross- multiply )

Answer:
x = 9/4
Step-by-step explanation:
2x - x + 9 + 3x - 2 = 16
Combine like terms

Subtract 7 from both sides
4x = 9
Divide both sides by 4
x = 9/4

(5*2+1)/5 =11/5
Copy dot flip
11/5 * -9/4
-99/20
Changing back to mixed number
-4 19/20
Answer:
-99/20 or -4.95
Step-by-step explanation:
make the first fraction a simple fraction by multiplying the denominator by the whole number and adding the numerator.
which equals 11/5. Then you multiple by the reciprocal of 4/-9 which is -9/4
to look like 11/5 * -9/4 = -99/20
what is the slope of (8,4), (4,4)?
Answer:

= (4-4)/(4-8)
= 0/-4
0
Answer:
zero
Step-by-step explanation:
(4-4) / (8-4) = 0/4
slope is zero which means it is a horizontal line which crosses the y-axis at 4

Which word describes their measures?
linear
congruent
complementary
supplementary
Answer: complementary
Step-by-step explanation:
Complementary angles are angles that add up to 90 degrees
The sum of the measure of angles 1 and 2 is the right angle which is 90 degrees. Then the correct option is C.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
Angles 1 and 2 form a right angle.
2 lines form a right angle.
Another line extends between the 2 lines to form 2 angles.
The top angle is labeled 1, and the bottom angle is labeled 2.
Then the sum of the measure of the angle 1 and 2 is the right angle which is 90 degrees. Then the angles are known as complementary angles.
Then the correct option is C.

Hi there!

Find the total area by breaking the figure into two rectangles, one trapezoid, and one triangle.
Rectangles:
A = l × w
A = 2.75 × 4 = 11 in²
Solve for the other rectangle's length by subtracting from the total:
12 - 2 - 3 - 4 = 3
A = 3 × 3 = 9 in²
Total rectangle area: 11 + 9 = 20 in²
Trapezoid:
A = 1/2(b1 + b2)h
A = 1/2(4.25 + 2.75)3 = 21/2 = 10.5 in²
Triangle:
A = 1/2(bh)
A = 1/2(2.5 · 2) = 2.5 in²
Add up all of the areas:
20 + 10.5 + 2.5 = 33 in²

Verify a ÷ b ≠ b ÷ a , if a = −3/4 and b = 4/5
Given:
[tex]a=-\dfrac{3}{4}[/tex]
[tex]b=\dfrac{4}{5}[/tex]
To verify:
[tex]a\div b\neq b\div a[/tex]
Solution:
We have,
[tex]a=-\dfrac{3}{4}[/tex]
[tex]b=\dfrac{4}{5}[/tex]
Now,
[tex]a\div b=\dfrac{a}{b}[/tex]
[tex]a\div b=\dfrac{-\dfrac{3}{4}}{\dfrac{4}{5}}[/tex]
[tex]a\div b=-\dfrac{3}{4}\times \dfrac{5}{4}[/tex]
[tex]a\div b=-\dfrac{15}{16}[/tex] ...(i)
And,
[tex]b\div a=\dfrac{b}{a}[/tex]
[tex]b\div a=\dfrac{\dfrac{4}{5}}{-\dfrac{3}{4}}[/tex]
[tex]b\div a=\dfrac{4}{5}\times (-\dfrac{4}{3})[/tex]
[tex]b\div a=-\dfrac{16}{15}[/tex] ...(ii)
From (i) and (ii), it is clear that
[tex]a\div b\neq b\div a[/tex]

A shipping container is in the shape of a right rectangular prism with a length of 5-5 feet, a width of 12 feet, and a height of 7.5 feet. The container is completely filled with contents that weigh, on average, 0.75 pound per cubic foot. What is the weight of the contents in the container, to the nearest pound?
Answer:
186 pounds
Step-by-step explanation:
volume : base area × height
area of rectangular triangle : a×b/2
Vp = (5.5 × 12 / 2) × 7.5 = 33 × 7.5 = 247.5 ft³
the weight of the contents : 247.5 × 0.75 = 185.625 pounds
