^{/2}\frac{z}{3} +^{6/}4= \frac{5}{6} \\  \\  \frac{2z}{6}  +  \frac{24}{6} = \frac{5}{6} => \\  \\ 2z=5-24 \\ 2z=-19 \\ z=-9.5

\frac{z}{3}+ \frac{12}{3}= \frac{5}{6} ⇒ \frac{z+12}{3}= \frac{5}{6}

z+12= \frac{5\cdot3}{6}=\boxed{2.5}

z=2.5-12

\boxed{\boxed{\boxed{z=-9.5}}}

Solve the equation for x, where x is a real number (5 points): <br> 2x^2 + 7x - 9 = -3
Tanya [424]
Add 3 to both sides so that the equation becomes 2x^2 + 7x - 6 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
                              x = [ -b ± √(b^2 - 4ac) ] / (2a)
                              x = [ -7 ± √(7^2 - 4(2)(-6)) ] / ( 2(2) )
                              x = [ -7 ± √(49 - (-48) ) ] / ( 4 )
                              x = [ -7 ± √(97) ] / ( 4)
                              x = [ -7 ± sqrt(97) ] / ( 4 )
                              x = -7/4 ± sqrt(97)/4
The answers are -7/4 + sqrt(97)/4 and -7/4 - sqrt(97)/4.

What is 1 6\10+ 5 2\10(what is 6\8- 2 4\8)what is 6 6\10- 4 4\10​
padilas [110]

Answer:

what is 1 6/10+5 2/10

=16/10 + 52/10 =

<u>16+52   =  68</u>

10              10

6/8-24/8

=6/8-20/8

<u>6-20 =  14</u>

8           8

6 6/10- 4 4/10

=<u>66-44 = 22</u>

10           10

Step-by-step explanation:

1/ if the fraction is mixed number example 2 1/7, it will be 2x7+1 and that will be 15 over 7

2/and if the bottom number example: 2 1/7, 7 is the bottom number and if 2 1/3 (3 is the bottom number) then see what the bottom number have in common example: 7-x1=7

7x2=14

7x3=21

3x1=3

3x2=6

3x3=9

3x4=12

3x5=15

3x6=18

3x7=21

so 21 is 7 and 3 have in common so the bottom number which is now 21 will divide 7 and got 3 and 3 will go on the top number 1 and 21 divide 3 which is 7 will go on the top number 1 and you continue to add your sum or subtract understand or not
