Answer:

x=-8z/5 - 3y/5

Step-by-step explanation:

distributive prop

3x-3y=8x+8z

isolate x by moving 8x to the left, and -3y to the right

-5x=3y+8z

divide by -5 on both sides.

x=-8z/5 - 3y/5

Answer:

Step-by-step explanation:

3(x - y) = 8(x + z)

3x - 3y = 8x + 8z

-3y - 8z = 8x - 3x

-3y - 8z = 5x

(-3y - 8z) / 5 = x ....or could also be written like : x = -3/5y - 8/5z

Step-by-step explanation:

$\log_42=0.5$

حن بحاجة إلى إيجاد $\log_432$

دع $\log_432=x$

$\log_42\times 2\times 2\times 2\times 2=x$

$\Rightarrow x=\log_42^5$

$\Rightarrow x=5\log_42$ $[\because \log_ab^x=x\log_ab]$

$\Rightarrow x=5\times0.5$

$\Rightarrow x=2.5$

$\mathbf{\therefore\log_432=2.5}$

HELP!!pls solve this rn pls. pls i rly need it now<br> 5 (-2a – 8 ) < -9a +4

Ann [662]

5(-2a-8) < -9a + 4

Use distributive property on left side:

-10a -40 < -9a + 4

Add 40 to both sides

-10a < -9a + 44

Add 9a to both sides

-a < 44

Multiply both sides by -1 and reverse the inequality sign:

A > -44

Answer: a > -44
