Answer:

Step-by-step explanation:

-3x - 6 = 18

The first step should be to add 6 to both sides.

- 3x = 24

The second step should be dividing each side by - 3x

X = - 8

28. How much plain yogurt will you need to make 2 1/2 dozen cookies? Show your work.

xxMikexx [17]

Answer:

$\frac{5}{6}$ cups

Step-by-step explanation:

Normally, when working with mixed numbers, I would prefer to turn them into improper fractions first before evaluating.

1 $\frac{1}{2}$ cookies --- $\frac{1}{2}$ cup plain yogurt

$\frac{3}{2}$ cookies --- $\frac{1}{2}$ cup plain yogurt

2 $\frac{1}{2}$ cookies --- ? cup plain yogurt

$\frac{5}{2}$ cookies --- $\frac{5}{3}$ × $\frac{1}{2}$ cup plain yogurt = $\frac{5}{6}$ cups plain yogurt

PLEASE HELP!

Answer:

c) A rectangle with width of 9 mm and length of 45 cm.

d) A rectangle with width of 10 cm and length of 44 cm.

Step-by-step explanation:

Given:

Length of the rectangle = 32 in.

Width of the rectangle = 8 in.

First we will find the ratio of length by width.

$\frac{length}{width}= \frac{32}{8} = \frac{4}{1} \ \ \ \ equation \ 1$

Now we need to find from the given Option which rectangles are not similar to Carl's Rectangle.

So we will check for each.

a) A rectangle with width of 23 cm and length of 92 cm.

we will find the ratio of length by width.

$\frac{length}{width}= \frac{92}{23} = \frac{4}{1} \ \ \ \ equation \ 2$

By Definition of Similar rectangles which states that;

"When ratio of the dimension of 2 corresponding rectangles are equal then the 2 rectangles are said to be similar."

Now Comparing equation 1 and equation 2 we get;

equation 1 $=$ equation 2

Hence This rectangle is similar to Carl's rectangle.

b) A rectangle with width of 2.5 inch and length of 10 inch.

we will find the ratio of length by width.

$\frac{length}{width}= \frac{10}{2.5} = \frac{4}{1} \ \ \ \ equation \ 2$

By Definition of Similar rectangles which states that;

"When ratio of the dimension of 2 corresponding rectangles are equal then the 2 rectangles are said to be similar."

Now Comparing equation 1 and equation 2 we get;

equation 1 $=$ equation 2

Hence This rectangle is similar to Carl's rectangle.

c) A rectangle with width of 9 mm and length of 45 cm.

we will find the ratio of length by width.

$\frac{length}{width}= \frac{45}{9} = \frac{5}{1} \ \ \ \ equation \ 2$

By Definition of Similar rectangles which states that;

"When ratio of the dimension of corresponding rectangles are equal then the 2 rectangles are said to be similar."

Now Comparing equation 1 and equation 2 we get;

equation 1 $\neq$ equation 2

Hence This rectangle is not similar to Carl's rectangle.

d) A rectangle with width of 10 cm and length of 44 cm.

we will find the ratio of length by width.

$\frac{length}{width}= \frac{44}{10} = \frac{11}{5} \ \ \ \ equation \ 2$

By Definition of Similar rectangles which states that;

"When ratio of the dimension of corresponding rectangles are equal then the 2 rectangles are said to be similar."

Now Comparing equation 1 and equation 2 we get;

equation 1 $\neq$ equation 2

Hence This rectangle is not similar to Carl's rectangle.
