Lunna [17]

Answer: SECOND OPTION

Step-by-step explanation:

You can solve the system of equations by the method of substitution:

- You must susbtitute the second equation into the first equation and solve or x:

$7x+2(x+1)=4\\7x+2x+2=4\\9x=4-2\\9x=2\\x=\frac{2}{9}$

- Now, you must susbtitute the value of x obtained above into the second equation to calculate the value of y. Then, you have:

$y=\frac{2}{9}+1\\\\y=\frac{2+9}{9}\\\\y=\frac{11}{9}$

Therefore, you obtain:

( $\frac{2}{9},\frac{11}{9}$ )

How do you write 6.359 × 10^-14 in standard form?

elixir [45]

$6.359*10^-^1^4$

Standard form:

$-6.359*10^-^1^4$

Since the exponent of the scientific notation is negative −14, move the decimal point 14 places to the left. 0.00000000000006359.

Chelsea and her friends are making small fruit baskets for their neighbors. They have 90 pears, 45 peaches, and 75 apples. What

iVinArrow [24]

Answer:

15 baskets

Step-by-step explanation:

This question is a GCF question

The first step would be to find the factors of 45, 75 and 90

The factors of 45 are: 1, 3, 5, 9, 15, 45

The factors of 75 are: 1, 3, 5, 15, 25, 75

The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

The greatest common factor is 15.

Therefore, the greatest number of baskets they can make if each basket has the same number of pears, the same number of peaches, and same number of apples, with no fruit leftover is 15 baskets
