The first equation will turn into -18x -6y = -18, and the second equation will turn into 14x + 6y = 18. The y terms will cancel out when you add the equations together.
Answer:
La respuesta es la C
Step-by-step explanation:
Primero tienes que hacer el 25% de ambas cantidades y luego sumarlo
Answer:
If you are adding to fractions that are both greater than 1/2, the sum will be greater than 1.
Step-by-step explanation: 1/2 + 1/2 =1
Since both fractions are greater, obviously the sum will too.
Examples: 2/3+3/4= 1 5/12 4/6+6/9= 1 1/3
Hope this helps
The price of all gallons 12*(2.89)=$34.68
a) the price of the granola bars 2*(1.59)=$3.18
b) 1 apple=$0.89
c) 2 bottles of vitamin 2*(1.39)=$2.78
a)+b)+c)=6.85$, the 7.5% of this amount is $0.51
so finally, Leon should have paid $6.85+ $0.51+ $<span>34.68 =$42.04
</span>
but he paid $44.64, so the true answer is C) he <span>paid $2.60 too much ($44.64 - $42.04 =$2.60)</span>
7 and -4
Coefficients are the numbers before a variable, meaning that 7 and -4 (be careful of that subtraction sign) are the coefficients. Additionally if you were asked what the leading coefficient was the answer would be 7 because it has the greatest exponent attached to it (2).
