<u><em>Answer: y=-6 and -6=y. *The answer should be the negative sign.*</em></u>

Step-by-step explanation:

division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.

a/c=b/c for c≠0

addition property of equality is adding the same number to both sides of an equation does not change the equation.

a+c=b+c

switch sides of an equation.

4y-4=-28

add by 4 both sides of an equation.

4y-4+4=-28+4

simplify by equation.

4y=-24

divide by 4 both sides of an equation.

4y/4=-24/4

simplify by equation.

24/4=6

24/6=4

6*4=24

4*6=24

y=-6 and -6=y

It changes to positive to negative.

Hope this helps!

Thanks!

Have a great day!

Answer:

y = -6

Step-by-step explanation:

-28 = 4y - 4

4y - 4 = -28

4y - 4 (+ 4) = -28 (+ 4)

4y - 4 + 4 = -28 + 4

4y = -24

4y/4 = -24/4

y = -6

Jack is running for city mayor. He stops the first 10 people on the street and asks them what their biggest concern for the city

olga2289 [7]

Jack's conclusion is B. INVALID. JACK DID NOT ASK ENOUGH PEOPLE.

A city has a population of millions and 10 people is not even a relevant sample of the population. Thus, the conclusion he has drawn based from his interview is insufficient.

Affect or use is 1/8 of a barrel of raisins in each batch of granola bars yesterday the factory use 1/2 of a barrel of raisins h

ahrayia [7]

Answer:

Factory made 4 batches of granola bars yesterday.

Step-by-step explanation:

Given:

1 batch of granola bar is made of 1/8 barrel of raisins.

1/8 barrels can be rewritten as 0.125 barrels.

Hence we can say 1 batch of granola bar is made of 0.125 barrels.

Also Given:

Yesterday Factory used 1/2 barrel of raisins.

1/2 barrels can be rewritten as 0.5 barrels.

Hence we need to find how much batches of granola bars were made using 0.5 barrels of raisins.

Now,

For 0.125 barrels raisins = 1 batch of granola bar

for 0.5 barrels of raisins = Batches of granola bar for 0.5 barrels of raisins

By Using Unitary method we get;

Batches of granola bar for 0.5 barrels of raisins = $\frac{1\times 0.5}{0.125}=4$

Hence Factory made 4 batches of granola bars yesterday.
