Answer:

20% x $95 = .20 x $95 = $19.

Step-by-step explanation:

Answer:

x = -4

Step-by-step explanation:

x-5 = -9

Add 5 to each side

x-5+5 = -9+5

x = -4

Answer:

A. x = -4

Step-by-step explanation:

x - 5 = -9 (plus 5 on each side to get rid on 5 on the left side) so -9 + 5

x = -4

Answer:

120 degrees

Step-by-step explanation:

Angles 1 and 3 are congruent, because they are vertical angles, so we must set them equal to each other, solve for x and plug in x.

Hope this helps :-)

Answer:

3 = 108 degrees

Step-by-step explanation:

2x + 80 = 3x + 60

get the variable and number on different sides

2x + 80 = 3x + 60

2x + 80 - 80 = 2x

3x + 60 - 3x = 60

2x + 3x = 5x

60 + 80 = 140

5x = 140

now divide each side by 5

5x / 5 = x

140 / 5 = 28

x = 28

28 + 80 = 108

Answer:

well the answer is (2,-5)

Step-by-step explanation:

The answer is (2,-5) is because on a graph none of the other Coordinates Match (-3,-5).

Answer: 80 sq. ft

Step-by-step explanation:

Company A’s charges can be represented by the equation: 10m + 250

Company B’s charges can be represented by the equation: 12m + 90

To find when the square feet got which they have the same amount, I will set them equal to each other and solve for it.

10m+250=12m+90

-10m -10m

250=2m+90

-90 -90

160=2m divide both side by 2

80=m

For 80 square feet, both companies charge the same amount.

Answer:

no

Step-by-step explanation:

A proportional relationship must go through the point ( 0,0).  This does not go through the origin so this is not proportional

The relationship is linear but non proportional. The graph is a line but it does not go through the origin.

Answer:

P=4x+20

A=x^2+10x+21

Step-by-step explanation:

Perimeter=2(x+7)+2(x+3)

2x+14+2x+6

4x+20

Area=(x+7)(x+3)

x^2+10x+21

l = (x + 3)

b = (x + 7)

Area:

= I x b

= (x + 3)(x + 7)

= x(x + 7) + 3(x + 7)

= x² + 7x + 3x + 21

= x² + 10x + 21

Perimeter:

= 2(l + b)

= 2((x + 3) + (x + 7)) = 2(2x + 10)

= 2(x + 3 + x + 7)

= 4x + 20

Answer:

Answer:

La cantidad de pasajeros que quedan en el avión serán [tex]\frac{1}{6}[/tex]

Step-by-step explanation:

Sabes que en el primer aeropuerto se bajan la mitad de los pasajeros, es decir que se bajan [tex]\frac{1}{2}[/tex] pasajeros, y en la segunda parada llegando a destino se bajan [tex]\frac{1}{3}[/tex] pasajeros. Entonces, la cantidad de pasajeros que se bajan en ambas paradas es la suma de la cantidad de pasajeros que se bajaron entre el primer y segundo aeropuerto:

[tex]\frac{1}{2}+\frac{1}{3}[/tex]

Lo primero que debes hacer es hayar un denominador común entre el 2 y el 3. Para eso, hallas el mínimo común múltiplo entre ambos, en este caso 6.

Luego debes multiplicar cada numerador por el número que hayas multiplicado el denominador. Para ello, dividis este mínimo común múltiplo entre el denominador inicial, y este resultado se multiplica por el numerador de esa fracción. De esta manera se obtiene:

[tex]\frac{1}{2}+\frac{1}{3}=\frac{3}{6} +\frac{2}{6}[/tex]

Finalmente se suman los numeradores y se obtiene:

[tex]\frac{1}{2}+\frac{1}{3}=\frac{5}{6}[/tex]

Considerando que 1 es un entero que representa la cantidad de total de pasajeros, para calcular la cantidad de pasajeros que quedan en el avión se realiza la sustracción:

[tex]1-\frac{5}{6}[/tex]

Resolviendo de manera similar a la suma, se obtiene:

[tex]1-\frac{5}{6}=\frac{6}{6} -\frac{5}{6}[/tex]

[tex]1-\frac{5}{6}=\frac{1}{6}[/tex]

Entonces la cantidad de pasajeros que quedan en el avión serán [tex]\frac{1}{6}[/tex]

Answer:

b = 2

Step-by-step explanation:

3b + 2(b - 3) = 4

--distributive property-- 2(b - 3) = 2b - 6

3b + 2b - 6 = 4

(add like terms)

5b - 6 = 4

(add 6 to both sides)

5b = 10

(divide both sides by 5 to get b alone)

b = 2

Answer:

30 - 3t ≤ 20

Step-by-step explanation:

Given that :

Pool is open when high temperature is higher than 20°C

From 30°C ; temperature decreased at a constant rate in the next three days ; that is the daily fall in temperature for 3 days is the same.

Let the fall or decrease in temperature = t

Constant decrease for 3 days = 3t

Change in temperature over 3 days :

Initial temperature - constant decrease

30°C - 3t

Hence, inequality to determine rate of temperature decrease :

30 - 3t ≤ 20

Answer:

22 blueberry pies and 19 apple pies.

Step-by-step explanation:

This can be solved using a system of equations. Your equation for amount of pies sold is x + y = 41, with x representing apple pies and y representing blueberry pies, and 41 being the total amount of pies sold. The other equation is for the amount of dollars earned from selling the pies, which is:

12x + 14y = 536     $12 per apple pie, $14 per blueberry pie, and a total of $536.

Let's first solve for x. The new equation would be x = 41 - y. Now, we plug this equation into the second equation.

12(41 - y) + 14y = 536    Here we substituted x for the equation we made.

429 - 12y +14y = 536

-12y +14y = 44   Here we moved the 429 to the other side by subtracting it from the left and right.

2y = 44

y = 22. Now we know that there was a total of 22 blueberry pies sold. Now we plug 22 pies back into the very first equation to find x, the amount of apple pies.

x + 22 = 41

x = 19. Now we know there was a total of 19 apple pies sold.

Hope this helps!

Answer:

109.6cm^2

Step-by-step explanation:

To find the area of a trapezoid the formula is (a+b)/2*h so for this problem, (12+15.4)/2*8= 27.4/2*8= 13.7*8=109.6cm^2

Hope this helped you out! :)

A(a) = 24 cm²

A(b) = 40.04 cm² ≈ 40 cm²

Hi there !

area formula (rectangle)

A = l × w

A(a) = 8cm × 3cm = 24 cm

A(b) = 5.2cm × 7.7cm = 40.04 cm² ≈ 40 cm²

Good luck !

Joy makes 6.5 litres soup correct to the nearest 0.5 litres. She serves the soup in 280ml portions correct to the nearest 10ml. 22 people order this soup. Does joy definitely has enough soup to serve the 22 people.

Answer:

Yes, Joy definitely does has enough soup

Step-by-step explanation:

From the question, we know,

Joy make 6.5 litres of soup

Serves it in 280ml portions

Step 1

We convert the portions to liters

1 ml = 0.001 litre

280 ml

= 280ml × 0.001 litre/1 ml

= 0.28litre

Step 2

We divide 6.5 liters by 0.28 to find out how many people can be served

= 6.5 ÷ 0.28

= 23.2142857143 people

We can see that 6.5 liters soup can serve 23 people approximately.

Therefore, Yes, Joy definitely does has enough soup to serve 22 people
