Answer:

x = 7

Step-by-step explanation:

In an isosceles triangle, both legs are always congruent. The length of one leg is given, and the other leg has to be the same. The perimeter of this triangle can be written as:

x+(3x-5)+(3x-5)=39

With this equation, all you need to do is solve for x.

3+3x-5+3x-5=39\\(-5-5)+(x+3x+3x)=39\\-10+7x=39\\7x=49\\x=7

A fence is being built around a rectangular garden. The length of the garden is 35 feet, and the total fencing used to enclose t
liraira [26]
The garden's width is 45. We know this because
35 \times 2
(length)
35 \times 2 + 2x = 160 \\
35x2 is 70 and you need to neutralize that by taking away 70 from both sides.
160 - 70 = 90
2x = 90
Now divide by 2 on both sides to neutralize the 2 times x.
90 \div 2 = 45
meaning that leaves us with
x = 45

You and some friends are going to the fair. Small rides costs 4 tickets and while big rides costs 7 tickets. You and your friend
tensa zangetsu [6.8K]

Answer:

<em>4x+7y≤250</em>

Step-by-step explanation:

<u>Inequalities</u>

Let's call:

x = number of small rides

y = number of big rides

Since each small ride costs 4 tickets, x rides cost 4x tickets.

Since each big ride costs 7 tickets, y rides cost 7y tickets.

The total number of tickets is the sum of both:

Total tickets = 4x+7y

The friends have 250 tickets, so the total tickets of the rides cannot be greater than the 250 tickets available, thus:

4x+7y≤250
