IN decimal form x=5.2 in mixed number form x=5 1/5

Answer:

x=5.2

Step-by-step explanation:

30-5x=4

x=5.2

Step-by-step explanation:

Simplify  6−3  to  3.

5×3=6+3

Simplify 5×3  to 15.

15=6+3

Simplify  6+3 to 9.

15=9

Since 15=9 is false, there is no solution.

No Solution

We have to use PEMDAS since there is parentheses, so we start with 6-3, which equals 3, then we can multiply that by 5, to get 15. Now the right side, that’s just simple addition, 6+3=9, so final answer is 15=9. Would appreciate brainliest!

how do you find the axis of symmetry?​

Answers

Answer:

The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .

Step-by-step explanation:

Answer:

x=-b/2a

Step-by-step explanation:

axis of symmetry is the line that across the vertex from a parabola(ax^2+bx+c).

The expression to find vertex is -b/2a

Thus, x=-b/2a is a vertical line that across the vertex aka the axis of symmetry.

A larger number is twelve more
than a smaller. Their sum is
84. Find the numbers.​

Answers

Answer:  bigger number is 48 and smaller number is 36

Step-by-step explanation:

Answer:

The smaller number  ⇒ y = 36The larger number ⇒ x = y + 12 = 36 + 12 = 48

Step-by-step explanation:

Let the larger number be = xLet the smaller number be = y

As the larger number is twelve more  than a smaller, so

x = y + 12

As the sum of larger and smaller numbers is 84, so

x + y = 84

now substituting x = y + 12 in th equation x + y = 84

x + y = 84

(y + 12) + y = 84

2y + 12 = 84

subtract 12 from both sides

2y + 12 - 12 = 84 - 12

2y = 72

divide both sides by 2

2y/2 = 72/2

y = 36

Thus,

The smaller number  ⇒ y = 36The larger number ⇒ x = y + 12 = 36 + 12 = 48

Three (3) consecutive integers is such that the largest is x. Write an expression
for the smallest.

Answers

Answer:

Consider 3 consecutive integers: (smallest) x, x+1 and x+2 (largest)

Step-by-step explanation:

Five times the smallest means 5x

Sum of the largest and five times the smallest means x+2+5x

This sum is -244 means x+2+5x=-244

Solve this equation

x+2+5x=-244

6x+2=-244

6x=-244-2

6x=-246

x=-41

So, smallest number is -41, second is -40 and largest is -39

You're answer is -39+5(-41)=244
