Jason solved the following equation to find the value for x. –8.5x – 3.5x = –78 x = 6.5 Describe how Jason can check his answer.
sweet-ann [11.9K]

Answer: Jason can substitute x=6.5 into the equation. The left side of the equation must be equal to the right side of the equation.

Step-by-step explanation:

The equation -8.5x-3.5x=-78 must be solved by calculating the value of the variable x:

Add like terms:

-12x=-78

Divide both sides by -12:

\frac{-12x}{-12}=\frac{-78}{-12}\\\\x=6.5

Once Jason solves for x, he has to substitute x=6.5 into the equation and simplify to check his answers.

If his answer is right, the left side of the equation will be equal to the right side of the equation.

Then:

-12(6.5)=-78\\-78=-78

x=6.5  is a solution of the equation.

Find the GCF and LCM of 217x328x11 and 213x345x74and explain your reasoning.
AfilCa [17]

Answer:

Given expressions are,

217 x 328 x 11

213 x 345 x 74,

Since, 217 = 7 × 31

328 = 2 × 2 × 2 × 41,

11 = 1 × 11,

So, we can write, 217 x 328 x 11 = 7 × 31 × 2 × 2 × 2 × 41 ×  1 × 11

Now, 213 = 3 × 71

345 = 3 × 5 × 23,

74 = 2 × 37,

So, 213 x 345 x 74 = 3 × 71 × 3 × 5 × 23 × 3 × 5 × 23

Thus, GCF ( greatest common factor ) of the given expressions = 1 ( because there are no common factors )

We know that if two numbers have GCF 1 then their LCM is obtained by multiplying them,

Hence, LCM ( least common multiple ) of the given expressions = 217 x 328 x 11 x 213 x 345 x 74
