8(t+2) - 3(t-4) = 6(t-7) + 8

Mathematics
1 answer:
Zinaida [17]3 years ago
7 0

Answer:

t = 50 is the solution for the given expression 8(t+2) - 3(t-4) = 6(t-7) + 8

Step-by-step explanation:

Here, the given expression is 8(t+2) - 3(t-4) = 6(t-7) + 8

Solving the given expression, we get

8t + 16  -3t + 12 = 6t - 42 + 8

or, 5t + 18  = 6t - 34

⇒  5t - 6t  = -34 -16

or ,   -t  = 50

or, t = 50

⇒ t = 50 is the solution for the given expression  8(t+2) - 3(t-4) = 6(t-7) + 8

Solution set is: (7,\frac{13}{3})

Option B is correct

Step-by-step explanation:

We need to find the solution to system of equations

y=\frac{1}{3}x+2\\y=\frac{4}{3}x-5

Let:

y=\frac{1}{3}x+2\,\,\,eq(1)\\y=\frac{4}{3}x-5\,\,\,eq(2)

Putting value of y from eq(2) into eq(1)

\frac{4}{3}x-5=\frac{1}{3}x+2\\Combining\,\,like\,\,terms:\\\frac{4}{3}x-\frac{1}{3}x=2+5\\Taking\,\,LCM\\\frac{4x-1x}{3}=7\\\frac{3x}{3}=7\\x=7

So, value of x=7

Putting value of x into equation 1 to find the value of y:

y=\frac{1}{3}x+2\\y=\frac{1}{3}(7)+2\\y=\frac{7}{3}+2\\Taking\,\,LCM\\y=\frac{7+2*3}{3}\\y=\frac{7+6}{3}\\y=\frac{13}{3}

So, value of y = \frac{13}{3}

Solution set is: (7,\frac{13}{3})

Option B is correct

Kate made 4 dresses with 7 yards of fabric. how many yards did she use on 1 dress
Ksju [112]
This is a fraction equal to
7 yards ÷ 4 dresses

We want a unit rate where
<span>1 is in the denominator, </span>
so we divide top and bottom by 4.

7÷4= 1.75
_
4÷4=1.
Therefore, Kate used 1.75 yards per one dress (1.75 yds. p/ d)

Hope I helped! :)

zysi [14]
.8 (88%)+.2x=90%
70.4%+.2x=90%

subtract 70.4% from 90% to get 19.6%
make the .2x into 2 and the 19.6 into 196
divide 196 by 2 to come up with the answer of 98%.
you will need a 98% to have a 90% for the final grade
