Answer:
34 weeks
Step-by-step explanation:
Hello!
We can set up an equation to solve for the number of weeks.
Let w = the number of weeks he is saving up.
The equation is 
- 315 is the target amount
- 115 is the current amount
- 10w is the rate of growth
- 140 is the current debt
<h3>Solve for w</h3>
He needs to save up for 34 weeks.
Answer: Assuming it means slope-intercept, the answer would be y=-2x+9
Answer:
48
Step-by-step explanation:
The consecutive numbers will be x and x + 1. Then write out the equation 2x + 1 = 99
Collect like terms
2x = 99 - 1
2x= 98
divide both sides by 2
x = 49
Answer:
Step-by-step explanation:
<u>According to the triangle inequality theorem, any side length is less than the sum of the other two:</u>
- x < 2x + 1 + x + 4 ⇒ x < 3x + 5 ⇒ 2x > - 5 ⇒ x > - 2.5
- 2x + 1 < x + x + 4 ⇒ 2x + 1 < 2x + 4 ⇒ 1 < 4, any value of x
- x + 4 < x + 2x + 1 ⇒ x + 4 < 3x + 1 ⇒ 2x > 3 ⇒ x > 3/2
<u>Common solution of the three inequalities above is:</u>
Correct choice is C
