Answer:

[tex]7 \frac{1}{2} [/tex]

Step-by-step explanation:

[tex]8 \frac{3}{4} - 1 \frac{1}{4} = \frac{35}{4 } - \frac{5}{4} \\ = \frac{30}{4} \\ = 7 \frac{2}{4} \\ = 7 \frac{1}{2} [/tex]

Answer:

it's 0.15

Step-by-step explanation:

1.45-0.85= 0.6

0.6 ÷ 4

15

Answer:

We are given that:

variables x and y vary directly, this means that:

y = kx where k is the constant of proportionality

Now, we are also given that:

y = 45 at x = 40.

We will use these values and substitute in the above relation to get k as follows:

y = kx

45 = 40k

k = 45/40 = 9/8 = 1.125

Based on the above calculations, the equation that relates x and y is:

y = 1.125x

Answer:

Multiply.

Step-by-step explanation:

2 * 15 = 30

5 * 37.50 = 187.5

6 * 45 = 270

8 * 60 = 480

480 + 270 = 750

187.5 + 30 = 217.5.

Step-by-step explanation:

simple: it will become 3 times 1/9 = 1/9+1/9+1/9 = 3/9 , which will eventually be 1/3, when both numerator and denominator will be divided by thier common factor that is 3

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.

Answer:

See below

Step-by-step explanation:

1. 223 is q added to 158

  223 = q + 158

2. d divided by 34 is the same as d

   d / 34 = d

3. 299/b = t

4. p = 204 × p

5. 103 is equal to m added to 343

    103 = m + 343

Hope that helps! :)

Answer:

[tex]2\frac{4}{5}[/tex]

Step-by-step explanation:

Rewriting our equation with parts separated

[tex]=9+\frac{1}{5} -6-\frac{2}{5}[/tex]

Solving the whole number parts

[tex]9-6=3[/tex]

Solving the fraction parts

[tex]\frac{1}{5} -\frac{2}{5} =-\frac{1}{5}[/tex]

Combining the whole and fraction parts

[tex]3-\frac{1}{5}=2\frac{4}{5}[/tex]

Answer:

y= _3x+55

Step-by-step explanation:

we conqet two points
(0,55)  (12,19)

55=B                       subsiquent two points into the equation
19=a,12+55
a=-3
b=55
so we choose B
