Answer:
1) 8x - 9
2) 5x - 2
Step-by-step explanation:
1) Given 8 times the difference between a number x and 9.
This means we should have:
Now using the distributive property we distribute 8 to x and 9 like:
. Thus the answer.
For 2) All the expressions except 4 equals . The last option is . Thus the answer.
This question is worded slightly strangely but I believe I understand it.
To eliminate x, multiply the second equation by 8, so that it becomes 4x + .8y= 96
<span>Then you can subtract 4x on the top by 4x on the bottom to eliminate it. </span>
I = Cxtxi
I = 1250 x 5 x (4.5 / 100)
I = 281.25
se obtendrá 281.25 al cabo de 5 años
Answer:
i think it’s 34
