Answer:
A las 15:00 horas la temperatura será de -15ºC, habiendo subido 12ºC desde el corte de luz.
Step-by-step explanation:
Dado que en un frigorífico la temperatura es de -27 °C, y después de un corte de luz a las 12:00 horas, la temperatura empieza a subir 2 °C cada media hora, para determinar cuál es la temperatura a las 15:00 horas, y cuánto ha variado la temperatura desde el corte de luz, se deben realizar los siguientes cálculos:
((15 - 12) x 2) x 2) - 27 = X
(3 x 2 x 2) - 27 = X
(6 x 2) - 27 = X
12 - 27 = X
-15 = X
Por lo tanto, a las 15:00 horas la temperatura será de -15ºC, habiendo subido 12ºC desde el corte de luz.
I'd suggest re-wording your question:
"How do I find the ordered pair (x,y) that solves this system of linear equations?"
One way of doing that would be to substitute y=5x+7 into the other equation:
-3x - 2(5x+7) = -12. Solve this for x. Once you have a value for x, subst. that value into y=5x+7 to find the corresponding y value.
Then write the ordered pair (x,y). That's it.

Record the data on the line plot. <---------------------> 1,3,1,1,2,2,3,3,4,5,4,3,1,2
igomit [66]
1 3
1 2 3
1 2 3 4
<---- 1 2 3 4 5---->
something like this.. where you put the numbers on top of one another in order creating a line plot of your data, with the numbers above the line
35 ÷ 5 = g
First, you snatch her/his money to do math, then you take the $35 and look the the thing that tells you how much games cost then do 35 ÷ 5 but since you cant solve it just put 35 ÷ 5 = g , and last but not least you take Kendle's money because no lazer tag during a pandemic and run home before you get yelled at because you were at a lazer tag place and took someones money.
