3/4(x+5 1/2) = 5/8 Distributive Property Brainly

Talja [164]

Answer:

x = - $\frac{14}{3}$

Step-by-step explanation:

Given

$\frac{3}{4}$ (x + 5 $\frac{1}{2}$ ) = $\frac{5}{8}$

Multiply both sides by 8 to clear the fractions

6(x + 5 $\frac{1}{2}$ ) = 5 ← distribute parenthesis on left side

6x + 33 = 5 ( subtract 33 from both sides )

6x = - 28 ( divide both sides by 6 )

x = $\frac{-28}{6}$ = - $\frac{14}{3}$

Please help me. these problems

jeyben [28]

Answer:

1st problem:

Converges to 6

2nd problem:

Converges to 504

Step-by-step explanation:

You are comparing to $\sum_{k=1}^{\infty} a_1(r)^{k-1}$

You want the ratio r to be between -1 and 1.

Both of these problem are so that means they both have a sum and the series converges to that sum.

The formula for computing a geometric series in our form is $\frac{a_1}{1-r}$ where $a_1$ is the first term.

The first term of your first series is 3 so your answer will be given by:

$\frac{a_1}{1-r}=\frac{3}{1-\frac{1}{2}}=\frac{3}{\frac{1}{2}=6$

The second series has r=1/6 and a_1=420 giving me:

$\frac{420}{1-\frac{1}{6}}=\frac{420}{\frac{5}{6}}=420(\frac{6}{5})=504$ .

You roll a dice twice. Find the probability of getting 3 in first throw and 5 in second throw.

Debora [2.8K]

Answer:

1/6

Step-by-step explanation:

there are 6 faces on a dice so there's a 1 in 6 chance that you would roll a 3 on your second go there is still only a 1 out of 6 chance of getting a 5 because there is still 6 numbers you could roll on.

hope this helped
