Simplify. (–8x) ÷ (–4)

1 answer:

7 0

(-8x) ÷ (-4)=0
First you have to divide both sides by -4:
2x ÷ 1=0
Now divide both sides by 1 so that the left side can be eliminated:
2x=0
Now divide both sides by 2 so that the left side only has x:
x=0

Peter rides a bike along a triangular path in the neighborhood park. The sides of the path measure 3.36 miles, 4.18 miles, and 5

Molodets [167]

Answer:

The distance that Peter rides is:

13.15 miles.

Step-by-step explanation:

To identify the miles that Peter rides, you must imagine the triangle with measures: 3.36 miles, 4.18 miles, and 5.61 miles. How you can suppose, Peter regularly rides exactly by each side of the triangle mentioned, then you must find the perimeter of the triangle to identify the miles that Peter rides, remember that the perimeter of an irregular triangle is:

Perimeter of a triangle = side + side + side

If you replace the formula, you obtain:

Perimeter of a triangle = 3.36 miles + 4.18 miles + 5.61 miles
Perimeter of a triangle = 13.15 miles

Which of the following are solutions to the equation below?

Natasha2012 [34]

Both A and C would be solutions to the equation.

In order to solve for this you must first get the equation equal to 0.

2x^2+5x+8=6 ----> subtract 6 from both sides
2x^2 + 5x + 2 = 0

Now knowing this we can use the coefficients of each one in descending order of power as a, b and c.

a = 2 (because it is the coefficient to x^2)
b = 5 (because it is the coefficient to x)
c = 2 (because it is the end number)

Now we can plug these values into the quadratic equation.

$\frac{-b +/- \sqrt{b^{2} - 4ac } }{2a}$

$\frac{-5 +/- \sqrt{5^{2} - 4(2)(2) } }{2(2)}$

$\frac{-5 +/- \sqrt{9} }{4}$

$\frac{-5 +/- 3 }{4}$

$\frac{-5 + 3 }{4}$ or -1/2 for the first answer

$\frac{-5 - 3 }{4}$ or -2 for the second answer

5. Henry hit 3 more than half as many home runs as Jack hit last season. Henry hit a total of 8 home runs. a. Make Sense and Per

Evgesh-ka [11]

Answer:

a. $3+\frac{x}{2} =8$

b. x = 10

Step-by-step explanation:

a. The number of home runs hit by Jack last season = x

It is given that Henry hit 3 more than half as many home runs as Jack hit.

Half of the runs hit by Jack = $\frac{x}{2}$

3 more than half the runs = $3+\frac{x}{2}$

So, the number of home runs hit by Henry = $3+\frac{x}{2}$

But, it is given that Henry hit a total of 8 runs.

Therefore, $3+\frac{x}{2} =8$

b. $3+\frac{x}{2} =8$

Subtract 3 from both sides.

$\frac{x}{2} =8-3$

= 5

x = 5 × 2

= 10

Hence, Jack hit 10 runs in the last season.

Order these numbers from least to greatest. 9.4061 , 9.07 , 9.007 , 9.4

klio [65]

9.4061,
9.07,
9.007,
9.4
Because ones are equal for all numbers, we are going to begin to compare from the second digits (tenths).
Greater :
9.4061 and 9.4.
Greatest is this group is 9.4061, then will go 9.4.

Smaller :
9.07 and 9.007
Greatest in this group is 9.07, and then will go 9.007.

So, from greatest to smallest : 9.4061 , 9.4 , 9.07 , 9.007.

From least to greatest :
9.007, 9.07, 9.4, 9.4061.
