Answer:
50
Step-by-step explanation:
3x = 25 - 5y
-100 < 5y < 50
-50 < -5y < 100
-25 < 25 - 5y < 125
-8.333 < x < 41.667
41+8+1 = 50
Answer:
25
Explanation:
We are given the sequence formula expression;
ax = 3x + 4
You are to get the 7th term. This is gotten by substituting x = 7 into the expression as shown;
a7 = 3(7) + 4
a7 = 21 + 4
a7 = 25
Hence the seventh term of the sequence is 25

Answer:
$3385 per week
Step-by-step explanation:
so, he gets $370 plus 4.5% of what he is selling.
$67000 = 100% of selling
1% = 100%/100 = 67000/100 = $670
4.5% = 1% × 4.5 = 670 × 4.5 = $3015
so, he gets $370 + $3015 = $3385 per week
