(a) Work out the value of I when x = 5 and y=-7
Answers
Note: Consider the dependent variable is T instead of I, and we need to find the value of T when x=5 and y=-7.
Given:
[tex]T=3x+4y[/tex]
To find:
The value of T when x=5 and y=-7.
Solution:
We have,
[tex]T=3x+4y[/tex]
Putting x=5 and y=-7, we get
[tex]T=3(5)+4(-7)[/tex]
[tex]T=15-28[/tex]
[tex]T=-13[/tex]
Therefore, the value of T is -13 when x=5 and y=-7.

Answers
Answer:60°
Step-by-step explanation: First, think about the rule of the degrees for all triangles. Angles must equal 180°.
Second, because all angles must equal 180°, see that the triangle given has equal sides (assuming this, because no other measurements are given).
Equilateral triangles have equal angles, meaning 60° for each angle.

Sarah drinks 30 liters of water on weekdays and 12 liters of water on weekends. How many liters of water does Sarah drink per day?
Answers
Easy, 6
30 divided by 5 equals 6
12 divided by 2 equals 6
Answer:
6 liters per day
Step-by-step explanation:
Hi there!
We know that Sarah drinks 30 liters on weekdays. There are 5 days in a week not including the weekends. You have to divide 30 liters by 5 to get the per day amount. 30 divided by 5 is 6. This means that Sarah drinks 6 liters per day. This is accurate because when you go on to check the amount of water she drinks on weekends, you know there are two days in a weekend, and you know she drinks a total of 12 liters during the weekend, so 6 liters multiplied by those two days is equal to 12.
Really hope this helps :)

$2.92. What is the percent of increase of a gallon of gasoline from June to
July? Round to the nearest tenth.
Answers
Answer:
6.2%
Step-by-step explanation:
Hard to explain, but easy. Take your new value, and subtract your initial (starting) value from the new value. In this case, it would be 2.95-2.75= 17. You now can take you difference (17) and divide it by the initial value, so 17/2.75. This gives you 6.181818182. Round to 6.2%
