Solve for xxx. Give an exact answer. 0.5(5−7x)=8−(4x+6)
bearhunter [10]

Answer:

x=-1

Step-by-step explanation:

0.5(5−7x)=8−(4x+6)

I do not like working with fractions so I will multiply by 2 on each side

2*0.5(5−7x)=2*8−2(4x+6)

5 -7x = 16 -2( 4x+6)

Distribute

5-7x = 16 -8x -12

Combine like terms

5-7x =4-8x

Add 8x to each side

5 -7x+8x = 4-8x+8x

5+x = 4

Subtract 5 from each side

5-5+x = 4-5

x =-1

Megan draws three different diagrams to represent the sample space of flipping a coin and rolling a 6-sided die.
erica [24]

Answer:

The explanation is given below.

Step-by-step explanation:

Given:

Two events take place.

Let event A be flipping a coin

Let event B be rolling a 6-sided die.

Now, a coin has two faces; one is head and the other is tail.

So, the possible outcomes of event A are: {H, T}

H → Head, T → Tail.

Now, a six sided die has six faces each marked with a number. The numbers marked ranges from 1 to 6.

So, the possible outcomes of event B are {1, 2, 3, 4, 5, 6}

Now, each element of set A should match with all the elements of set B.

Now, tabular form should have a row of outcomes of B and a coum of outcomes of event A. Thus,

Outcomes          1          2       3        4         5          6  

   H                 H1         H2     H3     H4       H5      H6

   T                 T1         T2     T3        T4      T5         T6

Therefore, the organised list has the following outcomes:

H1                 T1        

H2                T2

H3                T3

H4                T4

H5                T5

H6                T6

Finally, the correct tree diagram is attached below.

The population of a colony of beetles grows 30% each week. If the initial population is 65 beetles, how many beetles will be the
Crazy boy [7]
This is question of geometric sequence, equation of growth for this matter. The explicit formula for geometric sequence is given by:

a(n) = a(0)r^(n-1)

where;
a(n) = population after time "n"
a(0) = Initial population = 65
n = time = 5 weeks
r = common ratio = (100+30)% = 1.3

Substituting, beetles after 5 weeks will be;
a(5) = 65*1.3^(5-1) = 185.65 ≈ 186 beetles
