Group like terms, in this case terms with variables and terms without. (m + 11) + (n + 44) = (m + n) + (11 + 44) Then simplify. (m + n) + (11 + 44) = (m + n) + 55 = m + n + 55 Final answer: m + n + 55
the answers are:
complementary angles & adjacent angles
Answer:
All you have to do is substitute the value of x= -3 into the equation, then
g(-3) = -2(-3)2 + 3(-3) = -2(9) -9 = -18 - 9 = -27
Step-by-step explanation:
Here, we are required to compare the density of different liquids with the same volume
Since density is the ratio of mass to volume, different liquids for example, kerosene and water if they have the same volume, will have different masses.
This is due to the difference in their densities.
Therefore, according to the statement in the question above;
While comparing the density of Liquids with the same volume, the liquid with the greatest density is heavier(more quantity of matter per unit volume) while the liquid with the least density is lighter( less quantity of matter per unit volume).

Answer:
x = 12
y = 9
12 coins of dimes
9 coins of quartes
Step-by-step explanation:
x ---> coins of dimes
y ---> coins of quartes
x + y = 21
0.1x + 0.25y = 3.45 * 100
x + y = 21 L1
10x + 25y = 345 L2
x = 21 - y
Reemplace in L2
10(21 - y) + 25y = 345
210 - 10y + 25y = 345
15y = 345 - 210
15y = 135
y = 9
x = 21 - y
x = 21 - 9
x = 12
