Marking brainliest if correct Solve the PROPORTION 3/4 = 1/2y y=

Mathematics
1 answer:
Vladimir79 [104]3 years ago
4 0

Answer:

y=1 1/2 (fraction)

or

y=1.5 (decimal)

Step-by-step explanation:

We want to get y alone, so we need to get rid of the 1/2 in front of it. To do that we can multiply each side by 2 since 1/2 + 1/2 = 1.

3/4= 1/2y

multiply each side by 2

To multiply 3/4 by 2 you need to multiply the numerators and then multiply the denominators

2•3=6 & 4 • 1 =4

6/4

simplify

y=1 1/2

(If you need it in decimal form it would be y=1.5)

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

Convert a recipe that serves 6 and calls for 3/4 cups of sugar to one that serves 20.
djyliett [7]

Answer:

5/2cups

Step-by-step explanation:

If a recipe serves 6 and calls for 3/4cups, arecipe that serves 20, will call for (20×3/4)/6 cups. Mathematically;

6recipe = 3/4cups

20recipe = x

Cross multiplying we have;

6x = 20×3/4

6x = 15

x = 15/6

x = 5/2

This means a recipe that serves 20 will call for 5/2cups

Solve: 3(2x - 5) = 6x - 15
Levart [38]
3(2x-5)=6x-15

3(2x-5) :

6x-15 = 6x-15

add 15 to both sides:

6x-15+15=6x-15+15

6x =6x

subtract 6x from  both sides:

6x-6x=6x-6x

0=0

Both sides are equal : true  for all x

Answer D

hope this helps!
