2x + 2y = 4 -x+ 2y = 4​

Answers

Answer 1

Answer:

x = 0, y = 2

Step-by-step explanation:

We can use substitution method to substitute 2y into 2x + 2y = 4.

-x + 2y = 4

2y = 4 + x --- Equation 1

2x + 2y = 4 --- Equation 2

Substitute Equation 1 into Equation 2:

2x + 2y = 4

2x + 4 + x = 4

3x + 4 = 4

Isolate 3x.

3x = 4-4

    = 0

Find x.

x = 0 ÷ 3

x = 0

Substitute x = 0 into Equation 1:

2y = 4 + x

2y = 4 + 0

    = 4

Find y.

y = 4 ÷ 2

y = 2

Answer 2
The answer is Y=2 I’m pretty sure

a flour company in minneapolis wants to know what percent of local households bake at least twice a week. A company representative calls 500 randomly selected local households from 8am to 5pm during the week and finds that 56% of them bake at least twice a week

Answers

Answer:

Step-by-step explanation:

The response of this would be to say that those people without daytime jobs that are outside the home, are more likely to be home and thus, have more time on their hands to attempt to bake. So basically, the quoted 56% is definitely going to be higher than the population percentage.

16 oz.
$4.00
18 oz.
$5.40

Answers

Answer:

14oz for $2.80

Step-by-step explanation:

Well to determine the unit prices you must divide the price by whatever the weight is. As so:

10oz:  2.5/10=0.25

14oz:  2.8/14=0.20

16oz:  4/16=0.25

18oz:  5.4/18=0.30

So your answer is 14oz for $2.80

Answer: I’m pretty sure ur answer would be 14 oz. :)

70 + 95 = 5(14 + 19)

Step-by-step explanation:

To factor the expression, 70 + 95, using the GCF, take the following steps:

✔️Find the prime factors of each number:

Prime factors of 70 = 2 × 5 × 7

Prime factors of 95 = 5 × 19

Multiply the factors that both numbers have in common to get the GCF.

This, both number have only one factor in common which is 5.

Therefore, the GCF of 70 and 95 is 5.

✔️Factoring the experession given using the GCF, we have:

70 + 95 = 5(14 + 19)

Mrs. Anders gave her class 15 minutes to read. Courtney read 8 ½ pages in that time. At what rate, in pages per hour, would Courtney read?

Answers

Answer:

34

Step-by-step explanation:

15 mins is 1/4 od an hour so mulitply 8 1/2 (8.5) x 4

Answer:

First we figure out how many words in total she has to read.

This would be the (number of pages) times (number of words per page).

820 * 350 = 287000

so she has to read 287000 words

we divide this by 110 to get how long it would take for her to finish (in minutes)

287000 / 110 = 2609.09090909....

then since there are 60 minutes in an hour, we divide that number by 60

2609.09090909... / 60 = 43.48484848...

Therefore it would take her about 43.5 hours to complete her assignment.

It was founded in 1812 by the Russian-American Company as an agricultural colony to feed Russian fur trappers in Alaska. With a population of 250 at its peak, Fort Ross was actually the central hub for a number of even smaller outposts as far south as Bodega Bay and the Farallon Islands, located 40 miles north and 18 miles west of San Francisco, respectively. The Russians dismantled the colony in 1841. But Mexico was still worried about the threat of Russian expansion in their land, so they invited Anglo-American settlers to California as a buffer against Russian expansion from Alaska.
