you would divide 0.6 on both sides, because the main goal here is to isolate the y and to figure out the value of y. You would divide both the left and right of the equal sign and then be able to find the answer. 0.6/0.6=1. 10.3/0.6= 17.6 repeated, so we'll round to 17.67. The answer would be 17.67=1y, but since 1 can disappear and is not necessary when placed next to a variable, we can change the answer to 17.67=y.

we are given

10.3 = 0.6y

for finding y , we can isolate y

so, we can divide both sides by 0.6

\frac{10.3}{0.6} =\frac{0.6y}{0.6}

y=\frac{10.3}{0.6}

y=\frac{103}{6}.............Answer

algol13

Answer:

x

Step-by-step explanation:

\frac{7-2x}{-4} +2

Subtract 2 from both sides

\frac{7-2x}{-4}

mutliply both sides by -4, flip the inequality

7-2x >4x+8

Add 2x on both sideds

7>6x+8

Subtract 8 from both sides

-1>6x

Divide both sides by 6

Answer:

We conclude that:

\sqrt{\left(-81\right)x^2}=9ix

Step-by-step explanation:

Given the radical expression

\sqrt{\left(-81\right)x^2}

simplifying the expression

\sqrt{\left(-81\right)x^2}

Remove parentheses:  (-a) = -a

\sqrt{\left(-81\right)x^2}=\sqrt{-81x^2}

Apply radical rule:   \sqrt{-a}=\sqrt{-1}\sqrt{a},\:\quad \mathrm{\:assuming\:}a\ge 0

                 =\sqrt{-1}\sqrt{81x^2}

Apply imaginary number rule:  \sqrt{-1}=i

                 =i\sqrt{81x^2}

Apply radical rule:   \sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b},\:\quad \mathrm{\:assuming\:}a\ge 0,\:b\ge 0

                  =\sqrt{81}i\sqrt{x^2}

                  =9i\sqrt{x^2}

Apply radical rule:  \sqrt[n]{a^n}=a,\:\quad \mathrm{\:assuming\:}a\ge 0

                  =9ix

Therefore, we conclude that:

\sqrt{\left(-81\right)x^2}=9ix
