Answer:

\frac{0.2x + 1}{7}  = 0.4 \\ 0.2x + 1 =0.4 \times 7 \\ 0.2x + 1 = 2.8 \\ 0.2x = 2.8 - 1 \\ 0.2x = 1.8 \\ x =  \frac{1.8}{0.2}  \\   \boxed{x = 9}

  • <u>x</u><u> </u><u>= 9</u> is the right answer.

Answer:

9

Step-by-step explanation:

0.2x+1/7=0.4

multiply 7 on both sides.

0.2x+1=2.8

Minus 1 on both sides.

0.2x= 1.8

divide .2 on both sides

x=9!

I hope you get it!!

Consider a system of two linear equations in two variables. If the graphs of the equations are not the same line, is it possible
FinnZ [79.3K]

Answer:

No

Step-by-step explanation:

Solutions to systems of equations are points at which the lines of the equations intersect. Knowing this, only equations representing the same line would have infinitely many solutions because they would intersect at every one of each other's points - they're the exact same line. Therefore, if they are not the same line, they would not intersect at each and every point, and would not have infinitely many solutions.

Mrs. Benson has graded 46 math assignments but has 80% of the assignments left to grade. Mrs. Benson has how many math assignmen
timofeeve [1]

Mrs. Benson has 184 math assignments left to grade.

<u>Step-by-step explanation:</u>

Here we have , Mrs. Benson has graded 46 math assignments but has 80% of the assignments left to grade.We need to find Mrs. Benson has how many math assignments left to grade. Let's find out:

Let total Number of math assignments be x , So According to question 46 math assignments are graded & 80% are left i.e.

⇒ x = 46+\frac{80x}{100}

⇒ x -\frac{80x}{100}= 46

⇒ \frac{100x-80x}{100}= 46

⇒ \frac{20x}{100}= 46

⇒ \frac{x}{5}= 46

⇒ x=230

Now , Assignments left to grade is :

⇒ 230-46

⇒ 184

Therefore , Mrs. Benson has 184 math assignments left to grade.

Use the Distributive Property to write each expression as an equivalent algebraic expression. (7 + a)3 Question 4 options: 3(7a)
AysviL [449]

Answer:

(B)21+3a

Step-by-step explanation:

An expression is said to be distributive when:

(a+b)c=a \cdot c+b \cdot c

Given the algebraic expression: (7 + a)3

Applying the distributive property

(7 + a)3 = 7 \cdot 3+a \cdot 3\\=21+3a

An equivalent expression is 21+3a.

The correct option is B
