Answer:

t= -15/2       or       t= -7.5

Step-by-step explanation:

We are given the equation:

\frac{-6}{5}t=9

and asked to solve for t. Therefore, we must isolate t on one side of the equation.

t is being multiplied by -6/5. The inverse of multiplication is division. We should divided both sides by -6/5, but we are dividing by a fraction. Instead, we can multiply by the reciprocal.

To find the reciprocal, flip the numerator (top number)  and denominator (bottom number).

-6/5 ----> -5/6

Multiply both sides of the equation by -5/6

\frac{-5}{6} *\frac{-6}{5}t=9 *\frac{-5}{6}

t=9 *\frac{-5}{6}

t=\frac{9}1 *\frac{-5}{6}

Multiply across the numerator and denominator.

t= \frac{9*-5}{1*6}

t=\frac{-45}{6}

Simplify the fraction. Both the numerator and denominator can be divided by 3.

t=\frac{-45/3}{6/3}

t=\frac{-15}{2}

t= -7.5

t is equal to -15/2 or -7.5

Answer:

t= \frac{-15}{2}

Step-by-step explanation:

Multiply both sides by 5/(-6).

\frac{5}{-6} *\frac{-6}{5}=\frac{5}{-6}*9

ik the doesnt rlly make any sense but hope this helps

Unfortunately you didn’t provide the expressions to chose from

however, we can write :

(5g+3h+4) •2 = 2*5g + 2*3h + 2*4  (using distributive property)

                     = 10g + 6h + 8.

C(n)=-6+5(n-1)<br> find the 8th term in this sequence
Goryan [66]

Answer:

29

Just replace n by 8 ===> C(8) = -6+5(8-1) = - 6 + 5x7 = -6+35 = 29

Step-by-step explanation:

We have been given a sequence formula. We are asked to find the 8th term of our given sequence.

We know that an arithmetic sequence is in form A_n=a_1+(n-1)d, where,

A_n=\text{ nth term of sequence},

A_1=\text{ 1st term of sequence},

n = Number of terms in sequence,

d = Common difference.

To find the 8th term of our given sequence, we will substitute n=8 in our given formula.

c(n)=-6+5(n-1)

c(8)=-6+5(8-1)

c(8)=-6+5(7)

c(8)=-6+35
