Answer:

Trudy ate 3/4 a pound

Step-by-step explanation:

First, turn the 3 pounds into a fraction greater than 1. So 3 =3/1

Then multiply to see how many OF the blueberries Trudy eats (of means to multiply)

3/1 x 1/4 = 3/4

Answer:

This equation has 4 solutions, its real solutions are x = -1 and 3

Step-by-step explanation:

Correct for Plato Users

The equation has 4 solutions and its real solutions are 3, -1.

The given polynomial equation is 6(x - 3)(x² + 4)(x + 1) = 0.

A real solution in algebra is simply a solution to an equation that is a real number.

Now, 6(x - 3)(x² + 4)(x + 1) = 0

⇒(x - 3)(x² + 4)(x + 1) = 0

⇒(x - 3)=0, (x² + 4)=0 and (x + 1) = 0

⇒x=3, -1 and ±√-4.

Therefore, the equation has 4 solutions and its real solutions are 3, -1.

Answer:

C)  y=4x+1

Step-by-step explanation:

y=4x+1

Answer:

option c) y = 4x + 1

Step-by-step explanation:

(-1 , -3)   ; (2 , 9)

Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]

          [tex]= \frac{9-[-3}{2-[-1]}\\\\=\frac{9+3}{2+1}\\\\=\frac{12}{3}\\\\= 4[/tex]

Equation : y - y₁ = m(x - x₁)

             y - 9 = 4(x - 2)

             y - 9 = 4x  - 8

                 y  = 4x - 8 + 9

y = 4x + 1

Answer:

Number of drummers in original ensemble  [tex]=3[/tex]

Number of flutists in original ensemble [tex]=21[/tex]

Step-by-step explanation:

The ratio of flutists to drummers is [tex]7:1[/tex]

Let number of flutists and drummers be [tex]7x[/tex] and [tex]x[/tex].

As 2 drummers join the group and 6 flutists quit,

Number of drummers = [tex]x+2[/tex]

Number of flutists = [tex]7x-6[/tex]

New ratio of flutists to drummers = [tex]3:1[/tex]

So,

[tex]\frac{7x-6}{x+2}=\frac{3}{1}\\ 7x-6=3(x+2)\\7x-6=3x+6\\7x-3x=6+6\\4x=12\\x=3[/tex]

So,

Number of drummers in original ensemble  [tex]=x=3[/tex]

Number of flutists in original ensemble [tex]=7x=7(3)=21[/tex]

Answer:

Step-by-step explanation:

You keep the same slope since it's supposed to be parallel. But first you need to write it in slope intercept form. So the y can't have a number in front of it, so you must divided everything after the equal sign by the 3. So the equation becomes y=2/3x−1. Now you plug in the points to find a parallel equation using point slope form y−(4)=(23)(x−(−3)). Then you solve that and you get y=2/3x+6.

Answer:

4x10-4=36

Step-by-step explanation:

Lorenzo ate 1 bar from each. so 36 is left.

Answer:

4 × 10 - 4 = 36 granola bars

Step-by-step explanation:

4 packages with 10 bars each means 40 bars (4 packages × 10 bars each = 40 bars total)

one bar from each package

there are 4 packages so if he eats only one from each then he eats 4 bars total

40 bars total - 4 bars he ate = 36 bars left over

Answer:

[tex]\boxed {t = -1}[/tex]

Step-by-step explanation:

Solve for the value of [tex]t[/tex]:

[tex]5t + 16 = 6 - 5t[/tex]

-Take [tex]5t[/tex] and add to [tex]5t[/tex]:

[tex]5t + 16 + 5t = 6 - 5t + 5t[/tex]

[tex]10t + 16 = 6[/tex]

-Subtract [tex]16[/tex] to both sides:

[tex]10t + 16 - 16 = 6 - 16[/tex]

[tex]10t = -10[/tex]

-Divide both sides by [tex]10[/tex]:

[tex]\frac{10t}{10} = \frac{-10}{10}[/tex]

[tex]\boxed {t = -1}[/tex]

So, the value of [tex]t[/tex] is [tex]-1[/tex].

Rate is ratio that compares two quantities of different units.

A rate is a special ratio in which the two terms are in different units. Rate can also be defined as the ratio between two quantities of different units

For example, velocity is an example of rate, because it defined by the ratio of distance covered and time.

The unit of distance is metres and the unit of time is second. Therefore ;

velocity = distance /time. Therefore velocity is a rate.

Another example is ; Ade eat 5 mangoes for 20 days. The rate at which Ade eat is

1 day = 5/20

= 1/4 mangoes. This means Ade eats 1/4 mangoes per day.
