Solve the system by substitution.

-9y - 10 = x

5x+ 6y = -11

Answer:

(- 1, 3 )

Step-by-step explanation:

y = - x + 2 → (1)

3x - y = - 6 → (2)

Substitute y = - x + 2 into (2)

3x - (- x + 2) = - 6 ← distribute parenthesis and simplify left side

3x + x - 2 = - 6

4x - 2 = - 6 ( add 2 to both sides )

4x = - 4 ( divide both sides by 4 )

x = - 1

Substitute x = - 1 into (1)

y = - (- 1) + 2 = 1 + 2 = 3

solution is (- 1, 3 )

Answer:

Step-by-step explanation:

64.50=5x+58.50

64.50=5(1)+58.50

64.50=63.50 CORRECT

It can't be 2 because it will be over 64.50

5(2)+58.50

10+58.50

68.50 WRONG

Avery can use up to 1.2 gigabytes of data while staying within her budget of $64.50 per month.

The equation to determine the number of gigabytes of data Avery can use while staying within her budget can be written as:

$58.50 + $5x = $64.50

Where:

$58.50 represents the flat cost per month

$5x represents the cost based on the number of gigabytes used (x gigabytes)

$64.50 is the total budget she wants to stay within

To solve for x, we can subtract $58.50 from both sides of the equation:

$5x = $6.00

Then, divide both sides by $5:

x = 1.2

So, Avery can use up to 1.2 gigabytes of data while staying within her budget of $64.50 per month.

Answer:

Step-by-step explanation:

Given :- A taxi service charges $1.00 for the first 1/10 mile then $0.10 for each additional 1/10 mile after that. How much does it cost to go 2 miles in the taxi ?

Solution :-

→ charge for first (1/10) mile = $1

then,

→ distance left = 2 miles - (1/10) miles = (20 - 1)/10 = (19/10) miles .

Now,

→ charge for each additional 1/10 mile = $0.10

then,

→ charge for each additional 1 mile = $(0.10 * 10) = $1

So,

→ charge for each additional 19/10 mile = 1 * (19/10) = $(1.9)

therefore,

→ Total cost for 2 miles = 1.9 + 1 = $2.9 (Ans.)

Answer:

7/24

Step-by-step explanation:

Address formula, input values.

Input values

7 /6  &  4

7/6  ÷  4= ?

Multiply 7/6 with reciprocal of 4

= 7/6 x 1/4

The simplified form of the provided expression "7/6 divided by 4" is 7/24.

To simplify the expression 7/6 divided by 4, we can follow these steps:

First, let's represent the division as a fraction by placing the numerator (7/6) over the denominator (4): (7/6) / 4.

To divide fractions, we can multiply the numerator of the first fraction by the reciprocal of the second fraction. In this case, the reciprocal of 4 is 1/4.

Thus, we have (7/6) x (1/4).

To multiply the fractions, we multiply the numerators together and the denominators together. So, (7 x 1) / (6 x 4) = 7/24.

Therefore, the simplified form of 7/6 divided by 4 is 7/24.
