Solve for x.
Maksim231197 [3]

Answer:

1. 9x+4<58

x<6

2. 1x-2>3

x>1

Step-by-step explanation:

1. 9x+4<58

First, you need to group all the like terms ( the group of numbers that have the same variable), Also remember that, when a positive number crosses an inequality symbol, it becomes negative.

9x<58-4

Then, subtract the two numbers.

9x<54

Divide x's coefficient by 54 and you have your answer.

x<6

2. 1x-2>3

First, you need to group all the like terms. Remember that, when a negative number crosses an inequality symbol, it becomes positive.

1x>3-2

Then, subtract the two numbers.

1x>1

1 divided by one is one, so

x>1

Can anybody help me with this?
Anika [276]

Answer:

Step-by-step explanation:

it's 12 by 10, 12 x 10 = 120. because it's a triangle, you divide 120 by 2.

120 / 2 = 60. therefore the area of the triangle is 60. I also don't know the unit im supposed to use. is it centimeters? inches? miles?

For the annual rate of change of +70%, find the corresponding growth or Decay Factor.
omeli [17]
Hello there!
1. Okay. So 70% is positive, so it is a corresponding growth. 70% is 0.7 in decimal form. C and D are both eliminated, because that's too large. When something grows by 70%, that is less than double. 0.7 is not right either, because that's more of a decay than a growth. The only answer that makes sense id 1.70, because you are going up, and adding 1 to decimal form brings you to the decimal that when multiplied will bring you to the total. The answer is B: 1.70.

2. So, -75% is negative, so it is a decay factor. A is eliminated, because it makes no sense and B is out, because that represents growth, not decay. You lose 75% of the amount overtime compounded, but you still have 25% that remains. To find that amount, you would subtract that amount from 1 to get the decay. 1 - 0.75 is 0.25. The decay factor is 0.25. The answer is D: 0.25.

The expression 3t gives the number of tickets a player wins if he shoots the ball in the hoop t times. How many tickets would a
kari74 [83]

Answer: 48 tickets

Step-by-step explanation:

Since the expression that gives the number of tickets a player wins if he shoots the ball in the hoop t times is expressed as 3t.

Therefore, the number of tickets that a player wins if he shoots the ball in the hoop 16 times will be:

= 3t

where,

t = 16

Therefore, 3t = 3 × 16 = 48

The player wins 48 tickets.
