Which expressions does not represent 2/5?

16p=208 Plz answer and I'll give you brainliest.

Leno4ka [110]

Answer:

p = 13

Step-by-step explanation:

Step 1: Write equation

16p = 208

Step 2: Solve for p

Divide both sides by 16: p = 13

Step 3: Check

Plug in p to verify it's a solution.

16(13) = 208

208 = 208

Answer:

1) The correct option is C. (2) The correct option is D. (3) The correct option is B. (4) The correct option is D. (5) The correct option is D.

Step-by-step explanation:

The slope formula is

$m=\frac{y_2-y_1}{x_2-x_1}$

(1)

Two points are (-2,5) and (1,4).

$m=\frac{4-5}{1-(-2)}=\frac{-1}{3}tex]Therefore option C is correct.(2)Use the above mentioned formula for each pair of coordinates.[tex]m=\frac{10-13}{17-12}=\frac{-3}{5}$

$m=\frac{10-15}{13-16}=\frac{-5}{-3}=\frac{5}{3}$

$m=\frac{10-7}{3-0}=\frac{3}{3}=1$

$m=\frac{18-13}{8-11}=\frac{5}{-3}=\frac{-5}{3}$

Therefore option D is correct.

(3)

The pair of points (6, y) and (10, -1). The slope is $\frac{1}{4}$ .

$\frac{1}{4}=\frac{-1-y}{10-6}$

$\frac{1}{4}=\frac{-1-y}{4}$

$1=-1-y$

$y=-2$

Therefore option B is correct.

(4)

For vertical line the x coordinates always remains the same. Therefore when we subtract the same number we get zero in the denominator, therefore the value of slope is undefined for a vertical line.

Therefore option D is correct.

(5)

Two points from the table are (2,110) and (3,165).

$m=\frac{165-110}{3-2}=\frac{55}{1}$

Therefore option D is correct.

Yolanda has 2 granola bars. Each serving is of a bar of granola.

RSB [31]

The model of the granola bars is an illustration of ratios and proportions.

The model that shows the total serving is model A

The given parameters are:

$\mathbf{Bars = 2}$

$\mathbf{Serving = \frac{2}{5}}$

So, the number of servings in both bars is:

$\mathbf{Total = Bars \div Serving}$

Substitute 2 for Bars and 2/5 for Servings

$\mathbf{Total = 2 \div \frac{2}{5}}$

Express as multiplication

$\mathbf{Total = 2 \times \frac{5}{2}}$

$\mathbf{Total = \frac{10}{2}}$

$\mathbf{Total = 5}$

The total number of servings is 5

The model that shows a total serving of 5 is model A (see attachment)

Karen is seven years older than suzanne.Four years ago,karen was twice as old as suzanne was.How are they now?

Jlenok [28]

$x-\ Karen's\ age\\\\
y-\ Suzanne's\ age\\\\
 \left \{ {{x=y+7} \atop {x-4=2(y-4)}} \right.\\\\ \left \{ {{x=y+7} \atop {x-4=2y-8}} \right.\\\\ \left \{ {{x=y+7} \atop {x=2y-4}} \right.\\\\y+7=2y-4\ \ \ | subtract\ 2y\\\\
-y+7=-4\ \ \ | subtract\ 7\\\\
-y=-11\ \ \ | multiply\ by\ -1\\\\
y=11\\\\
x=11+7=18\\\\
Now\ Karen\ is\ 18\ years\ old \ and\ Suzanne\ is\ 11\ years\ old.
