Answer:

Step-by-step explanation:

JL = JK + KL

84 = 3x+5 + 6x+7

Combine like terms

84 = 9x +12

Subtract 12 from each side

84-12 = 9x+12-12

72 = 9x

Divide by 9

72/9 = 9x/9

8 =x

We want KL

KL = 6x+7

6*8 +7

48+7

Katen [24]

Teacher will have 3 bottles of glue after he combines

Solution:

Given that,

The art teacher has 7 bottles of glue that are each 2/5 full

He combines them so he will have fewer bottles

To find: bottles of glue does he have after he combines them

From given,

Total bottles = 7

Each is 2/5 full

Therefore, multiply 7 with 2/5 to get total bottles of glues he will have after combining

$Number\ of\ bottles\ of\ glues = 7 \times \frac{2}{5}\\\\Number\ of\ bottles\ of\ glues = \frac{14}{5} = 2.8 \approx 3$

Thus teacher will have 3 bottles of glue after he combines
