If you want to use integer tiles to find the product of 2(-5), think of it as you having 2 groups of 5 negative tiles, that is
-1 -1
-1 -1
-1 -1
-1 -1
-1 -1
Think of it as you having each of the -1 inside it's distinct tile. Now adding up these tiles you have -10.
Therefore 2(-5) is -10 using integer tiles.
If we are to use the number line, first draw your number line, then think of it as jumping twice while each jump is -5 big.
So the first jump from 0 will land on -5 and the second jump will land on -10 and that is the required answer using the number line.
Answer:
sup i know im late but still
Step-by-step explanation:
With integer tiles, you would add 5 groups of negative 2 tiles or remove 2 groups of 5 positive tiles. On the number line, you would bounce by 5 to the left 2 times. - this was the sample response on edge.

Teresa has a $100 gift card to her favorite restaurant. Each day, she uses her gift card to buy the same lunch for $8.50. Colin has a $75 gift card to the same restaurant. His lunches cost $6 each. Which inequality shows Teresa's gift card balance to be greater than Colin's gift card balance?
Answer:
Thinking about the equation and the depth I believe that the inequality would be:
100 is greater than 75. If not that I would think the answer is 100-8.50 is greater than 75-6. The last resort would be 12 is greater than 11.

PLZ HLP Given the equation 5x + y = 7, which equation below would cause a consistent-independent system?
Group of answer choices
10x + 2y = 14
−15x − 3y = −6
6x + 2y = 7
5x + y = −7
Answer:
the equation D ) would cause a consistent-independent system.
Step-by-step explanation:
A ) 5 x + y = 7 /*( -2 )
10 x + 2 y = 14
--------------------
- 10 x - 2 y = - 14
10 x + 2 y = 14
------------------------
0 x = 0 ( Dependent system )
B ) 5 x + y = 7 / * 3
- 15 x - 3 y = - 6
--------------------------
15 x + 3 y = 21
- 15 x - 3 y = - 6
-------------------------
0 x = 15 ( Inconsistent system )
C ) 5 x + y = 7
5 x + y = - 7 / * ( - 1 )
---------------------------
5 x + y = 7
- 5 x - y = 7
------------------
0 x = 14 ( Inconsistent system )
D ) 5 x + y = 7 / * ( - 2 )
6 x + 2 y = 7
------------------
- 10 x - 2 y = - 14
6 x + 2 y = 7
-----------------------
- 4 x = - 7; x = 7/4; y = - 7/4

(x, y) = (0.5, 2.5)
Step-by-step explanation:
The first equation has a slope of 1 and a y-intercept of 2.
The second equation has a slope of -1 and a y-intercept of 3.
The two lines cross at the point (0.5, 2.5), which is the solution to the system of equations.

a) Sorry, I submitted the question before screen clipping the graph
b) X=0.5 Y=2.5
Step-by-step explanation:
Draw both lines, and the coordinates which the 2 lines cross at equals x and y.
Someone please help I don’t understand!!!
Answer:
y=3
Step-by-step explanation:
This is because it is a straight line, there is no need for x-intercepts or y-intercepts because it already intercepts y at y=3.So, your answer is y=3

Metro cable tv tuvo ventas de 2500000 en su primer año de funcionamiento. Si a partir de entonces las ventas aumentaron 12% con respecto al año anterior, calcule las ventas de la empresa en el quinto año y las ventas totales durante los primeros 5 años de operación
Explicación paso a paso:
Dado
Principal = 2,500,000
Tasa = 12% (anual)
tiempo = 5 años
Incremento después del primer año = 12% de 2.500.000
= 12/100 * 2,500,000
= 12 * 25000
= 300.000
El monto al final de los 5 años se calculará utilizando la fórmula de interés compuesto;
A = P (1 + r) ^ n
A = 2500000 (1 + 0,12) ^ 5
A = 2500000 (1,12) ^ 5
A = 2500000 (1,7623)
A = 4.405.854,208
Por lo tanto, las ventas totales durante los primeros 5 años de operación son 4.405.854,208
Obtenga la cantidad obtenida en el quinto año
El monto al final de los 4 años se calculará utilizando la fórmula de interés compuesto;
A = P (1 + r) ^ n
A = 2500000 (1 + 0,12) ^ 4
A = 2500000 (1,12) ^ 4
A = 2500000 (1,5735)
A = 3.933.798,4
Utilidad obtenida en el quinto año = 4.405.854,208 - 3.933.798,4
A = 4.405.854,208 - 3.933.798,4
A = 472.055,808
Por lo tanto, la ganancia obtenida en el quinto año es de 472,055.808
Monto realizado en el quinto año = Principal + intereses en el quinto año
Monto realizado en el quinto año = 2500000 + 472,055.808
Monto realizado en el quinto año = 2,972,055.808

George purchased a concert ticket on a web site. The original price of
the ticket was $85. He used a coupon code to receive a 15% discount.
The website applied a 10% service fee to the discounted price. George's
ticket was less that the original price by what percent?
15%
10%
6.5%
8.5%
Answer:
6.5%
Step-by-step explanation:
The original price of the ticket was 100% of the price of the ticket.
The 15% coupe reduced the price to 85% of the price of the ticket.
The 10% fee on the discounted price adds 10% of 85% to 85%, so it adds 8.5% to 85%. By adding the fee he is at 93.5% of the original price.
100% - 93.5% = 6.5%
The overall percent off compared to the original price was 6.5%.
Answer: 6.5%

Write an expression for the sequence of operations described below. triple v, then subtract 7 from the result Do not simplify any part of the expression.
Given:
The sequence is defined as "triple v, then subtract 7 from the result".
To find:
The expression for the given sequence.
Solution:
Triple v means 3 times of v, i.e., 3v.
So, the result is 3v.
Then subtract 7 from the result. So, the expression for the sequence is
[tex]3v-7[/tex]
Therefore, the required expression is [tex]3v-7[/tex].

Fahim is 6 feet tall. At noon, he stands with the sun behind him casting a shadow. The distance from the top of Fahim's head to the furthest tip of the shadow is 13 feet. A right triangle with side length 6 feet, s, and hypotenuse 13 feet. [Not drawn to scale] What is the length of Fahim's shadow? Round to the nearest tenth of a foot. 7.0 feet 8.5 feet 11.5 feet 14.3 feet
Answer: 11.5 feet
Step-by-step explanation:
We should note that for a right angles triangle, the square of the hypothenuse equals to the square of the opposite side and its adjacent. This can be expressed as:
Let the length of Fahims shadow be x
hypotenuse² = opposite² + adjacent ²
13² = 6² + x²
169 = 36 + x²
x² = 169 - 36
x² = 133
x =✓133
x = 11.53
= 11.5 feet to nearest tenth

11.5 feet

Sonia es apicultora y en su planta de envadasado la maquina envasa 1920 tarros por hora, que luego se agrupan por tamaños; los frascos grandes se agrupan en cajas de una docena y los medianos en cajas de 20 unidades. ¿ si la maquina solo envasara frascos de un tipo , cuantas cajas de frascos grandes envasaria cada hora? Y de frascos medianos?
Answer:
En una hora, la máquina podría envasar 160 cajas de frascos grandes, o 96 cajas de frascos medianos.
Step-by-step explanation:
Si la maquina solo envasara frascos de un tipo, y pudiese envasar 1920 tarros por hora, para determinar cuantas cajas de frascos grandes envasaría cada hora hay que realizar el siguiente cálculo:
1920 / 12 = X
160 = X
Así, en una hora, la máquina envasaría 160 cajas de frascos grandes.
Por otra parte, en caso de envasar frascos medianos, el cálculo sería el siguiente:
1920 / 20 = X
96 = X
Por ello, la máquina envasaría 96 cajas de frascos medianos en una hora.

Step-by-step explanation:
divide it I hope it helps
Answer:
241.20 dollars
Step-by-step explanation:
Use the equation I=prt, where I is the interest and p is the percentage of simple interest, which is 6% or 0.06. T is the rate of time in years. R is the amount Felix deposited. Our equation would be:
I=(0.06)(1340)(3)
I=(0.18)(1340)
