Answer:

x=2

Step-by-step explanation:

Add all the sides to find the perimeter

x+4 + 4x+10(x-1) = 24

Distribute

x+4+4x +10x-10 = 24

Combine like terms

15x -6 = 24

Add 6 to each side

15x-6+6 = 24+6

15x = 30

Divide each side by 15

15x/15 = 30/15

x = 2

Hey!

Okay, to solve this problem, we'd first have to multiply both sides by two. The reason we do this is to get $y$ on its own.

Original Equation : 
$\frac{y}{2}$ < $-3$

New Equation {Changed by Multiplying 2 on Both Sides} :
$\frac{2y}{2}$ < $2$ ( $-3$ )

And we simplify the equation to get our answer.

Old Equation :
$\frac{2y}{2}$ < $2$ ( $-3$ )

New Equation {Changed by Simplification} :
y < -6

So, the equation $\frac{y}{2}$ < -3 simplified is y < -6.

Hope this helps!

A coin is tossed three times. what is the probability of getting two heads and one tail?

Lera25 [3.4K]

If the order doesn't matter, then the probability is 37.5%
If it has to be head head tail, then the probability is 12.5%

If the order doesn't matter, the possible outcomes that have two heads and one tail are HHT, HTH, and THH. Since these all have a probability of 12.5% of occuring, the probability of any of them occuring is 37.5%

4 - t = 3(t-1) - 5 A 3 B 6 C no solution D Identity

Ket [755]

Answer:

Step-by-step explanation:

Given

4 - t = 3(t - 1) - 5 ← distribute and simplify right side

4 - t = 3t - 3 - 5

4 - t = 3t - 8 ( subtract 3t from both sides )

4 - 4t = - 8 ( subtract 4 from both sides )

- 4t = - 12 ( divide both sides by - 4 )

t = 3
