Fittoniya [83]

Answer:

See below

Step-by-step explanation:

1. (refresh if you cant see it)

$F = \frac{9}{5}C+32\\\text{Bring variable C to left side}\\-\frac{9}{5}C=-F+32\\\text{Multiply by -1}\\\frac{9}{5}C=F-32\\\text{Multiply the equation by 5/9 to get C by itself}\\C = \frac{5}{9}(F-32)$

2(x + 3) = 20

Distribute.

2x + 6 = 20 $\neq$ 2x + 3 = 20

Your answer is false.

x $\geq$ -2 because even though it includes the expression "x>5", those values are also above -2, including 5.

2(x)+2(2)=2(x/2)-2(x) Solve this please and show the steps!!!!!!

Olin [163]

Answer: $x=-\frac{4}{3}$

Step-by-step explanation:

$2(x)+2(2)=2(\frac{x}{2})-2(x)$

Remove all those parentheses by multiplying. Note: 2 and 2 cancel out.

$2x+4=x-2x$

Subtract 2x

$4=x-2x-2x$

Combine like terms;

$4=-3x$

Divide by -3

$\frac{4}{-3}=x$

Rewriting it;

$x=-\frac{4}{3}$

Find out for what value of the variable:

Burka [1]

Answer:

$a=-1,\ a=-5$

$x=-2+i,\ -2-i$

Step-by-step explanation:

Equations

We have two cases where some variable is required to be found such that some condition is met. The first case is about finding the value of a that complies:

$a^2+7a+6=a+1$

Rearranging

$a^2+6a+5=0$

Factoring:

$(a+1)(a+5)=0$

There are two solutions:

$a=-1,\ a=-5$

The second case requires us to find the value of x such that

$3x^2-x+1 =2x^2+5x-4$

Rearranging

$x^2+4x+5=0$

This second-degree equation has no real roots. We'll offer the imaginary (complex) solutions:

$x=-2+i,\ -2-i$

Is 1/2 greater than 4/5

Law Incorporation [45]

For this question you should know:
1/2 = 5/10
and
4/5 = 8/10
so you can see 8/10 is greater than 5/10 so the answer is no
4/5 is greater than 1/2 :)))
i hope this is helpful
have a nice day
