Answer:
2.995 ou 35.940 (?)
Step-by-step explanation:
Não me lembro exatamente como fazer isso, vou mostrar duas maneiras diferentes de resolver isso.
Use a fórmula l = P * r * t
| = Juros
P = Principal
r = taxa
t = tempo
Para resolver isso, você terá que ... O principal é 29.950, a taxa é 5%, mas se tornará um decimal que é 0,05, e o tempo é 2 Coloque-o na forma de fórmula 29.950 * 0,05 * 2 = 2.995 em interesse
Ou .. Você usará a mesma fórmula, mas desta vez multiplique 0,05 por 12, pois há 12 meses em um ano que é 0,6, então ... 29.950 * 0,6 * 2 = 35.940 de juros
Espero que funcione!
<span>–1 + 6(–1 – 3x) > –39 – 2x.
Multiply the number outside of the parenthesis(6) by the numbers inside of the parenthesis(-1 and -3x)
-1 - 6 - 18x> -39 - 2x
Add 2x to both sides so that the x variable is only on one side
-1 - 6 - 16x> -39
Add 1 to both sides
-6 - 16x> -38
Add 6 to both sides
-16x> -32
Divide both sides by -16 so that the only thing that remains is the variable x on one side. Also, since you are dividing by a negative number, you automatically flip the greater than side to less than.
Final Answer: x< -2</span>
Answers : A and D
Step - by - step explanation :
tip : when finding constant of proportionality it's always Y divided by X
A = what is 22.5 divided by 3 ? 7.5 ( now multiply 7.5 by the next X [ 4 ] )
what is 7.5 x 4 ? 30 ( and since on the graph it also says 30 then you can assume this one has a proportional relationship )
B = what is 12 divided by 3 ? 4 ( now multiply 4 by the next X [ 5 ] )
what is 4 x 5 ? 20 ( and because the graph says 25 then you know it's NOT a proportional relationship )
C = what is 8.5 divided by 2 ? 4.25 ( now multiply 4.25 by the next X [ 5 ] )
what is 4.25 x 5 ? 21.25 ( and because the graph says 22.5 then you know it's NOT a proportional relationship )
D = what is 10 divided by 2 ? 5 ( now multiply 5 by the next X [ 3 ] )
what is 5 x 3 ? 15 ( and since on the graph it also says 15 then you can assume this one has a proportional relationship )
( sorry it took me so long to write this )
Answer:
Step-by-step explanation:
The given expression is
We group the constant terms on the right hand side to obtain;
We square both sides of the equation to remove the square root.
This will simplify to;
The answer is 456
This the answer 456
