Practice proportionality. A 50 difference between 100 and 150 is less relevant than 50 in 25 and 75. Its like you have 1 billion dollars and i give you 10 dollars. Its worthless right? What if you have 20 dollars and i give you again 10 dollars, its half of what you have. See the difference? Same number but different value.
75 / 15 = 5
whe the question says "how many times does y go in to x " you reverse the numbers and divide
Y = 6x - 11
-2x - 3y = -7
Let's use substitution:
-2x - 3y = -7
-2x - 3(6x - 11) = -7
-2x - 18x + 33 = -7
-20x + 33 = -7
-20x = -40
x = 2
----
y = 6x - 11
y = 6(2) - 11
y = 12 - 11
y = 1
----
y = 6x - 11 => 1 ? 6(2) - 11 => 1 = 12 - 11 <--True
-2x - 3y = -7 => -2(2) - 3(1) ? -7 => -4 - 3 = -7 <--True
Answer:
x = 2
y = 1
Hope this helps!
Answer:
D is incorrect
Step-by-step explanation: A is correct because there are 12 cars and 7 trucks. B is correct because there are 7 trucks and 12 cars. C is correct because there are 12 cars and 19 total vehicles(7+12=19). D is incorrect because while there are 7 trucks, there are not 12 vehicles in TOTAL.
if you had the final answer you would divide it by the number of friends
