1/4 times the sum of a number and −3.2 is 1.8

What is the number?

Enter your answer as a simplified mixed number.

Answers

Replace the unknown number as x. You know that (x-3.2)1/4=1.8. Multiply (x-3.2)1/4 by four to cancel out the 1/4 and do the same with 1.8 on the other side. This will leave you with x-3.2=7.2. Add +3.2 to both sides of the equation to cancel out the -3.2 and it leaves you with x=10.4. Your answer is 10.4

The mixed number for the  given case can be obtained as 10²/₅.

How to write a linear equation?

A linear equation for the given case can be written by assuming any variable as the unknown quantity. Then, as per the given data the required operations are done and it is equated to some value.

Suppose the number be x.

Then, the following equation can be written for information given as,

1/4(x - 3.2) = 1.8

It can be solved as,

x - 3.2 = 1.8 × 4

⇒ x = 7.2 + 3.2 = 10.4

It can be written in mixed form as below,

10.4 = 10 + 4/10

⇒ 10 + 2/5 = 10²/₅

Hence, the required number is 10²/₅.

First fine 5% of 720 which is 36
Then find 1% of 720 which is 7
Then 0.25% of 720 which is 0.75
Now add them together to find 6.25% which is equivalent to 43.75

A parabola with no real zeros, a negative leading coefficient, and an odd y-intercept.
pls help!

Answers

Answer:

Step-by-step explanation:

A parabolic graph with no real zeros never touches or crosses the x-axis.  

If the leading coefficient is negative, that tells us that the parabola opens down (and, in this case, that the entire graph is below the x-axis, because there are no real zeros.

If the y-intercept is odd, then the constant term, c, in ax^2 + bx + c, must be a negative, odd integer.

Suppose we say that the vertex of a particular parabola that is described by the above is (-2, -1) and that the y-intercept is -3.  (Note:  this is strictly an example.)  Then the vertex equation of this parabola is obtained from the general vertex equation of a parabola,

y = a(x - h)^2 + k.  Here h = -2 and k = -1, and so the particular parabola is

y = -a(x + 2)^2 - 1, where a is a constant and -a is negative.

In general form, this would be y = -a(x^2 + 4x + 4) - 1, or

                                                   y = -ax^2 - 4ax - 4a -1

and the constant terem (-4a -1) must be an odd negative integer

This is only one of an infinite number of possible equations for the parabola described above.

What is the cost of 2.6 pounds of cheese at $6.75 per pound
WORTH A LOT OF POINTS BRAINLIEST IF CORRECT

Answers

Answer:

$17.55

Step-by-step explanation:

simply multiply the price by the amount of the product so: 2.6*6.75= 17.55

We can write the information given mathematically:
1 pound of cheese = $6.75

We need to find the price of 2.6 pounds of cheese and we can do this by multiplying both sides of the equation above by 2.6:

1 pound of cheese = $6.75
1 x 2.6 pounds of cheese = $6.75 x 2.6

2.6 pounds of cheese is $17.55
