Icated (Q#1-4).<br> 2. Solve by substitution; x+3y + 4)<br> 3x - 5y = 8<br> 3 (3x+4)<br> aytla
puteri [66]

Answer:

See explanation

Step-by-step explanation:

Assuming your system is:

x + 3y = 4

3x - 5y = 8

Then make x the subject in the first equation to get:

x = 4 - 3y

Put this equation into the second equation to get:

3(4 - 3y) - 5y = 8

12 - 9y - 5y = 8

- 9y - 5y = 8 - 12

-14y =  - 4

y =   \frac{ - 4}{ - 14}  =  \frac{2}{7}

This means that:

x = 4 - 3 \times  \frac{2}{7}

x = 4 -  \frac{6}{7}  =  \frac{22}{7}

A group of twelve friends went bowling. The regular price was $8.00. The bowling alley offered a discount price of $6.00 to coll
olga2289 [7]

Answer:

x = friends that paid discount price = 8

y = friends that paid regular price = 4

Step-by-step explanation:

Let

x = friends that paid discount price

y = friends that paid regular price

x + y = 12 (1)

6x + 8y = 80 (2)

From (1)

x = 12 - y

Substitute x = 12 - y into (2)

6x + 8y = 80 (2)

6(12 - y) + 8y = 80

72 - 6y + 8y = 80

- 6y + 8y = 80 - 72

2y = 8

y = 8/2

y = 4

Substitute y = 4 into (1)

x + y = 12 (1)

x + 4 = 12

x = 12 - 4

x = 8

x = friends that paid discount price = 8

y = friends that paid regular price = 4

A 30 foot ladder is set against the side of a house so that it reaches up 24 feet. If Alexander grabs the ladder at its base and
lana66690 [7]

Answer:

The answer would be 10.8

Step-by-step explanation:

By finding the missing base side on the original triangle (which is 18), we add 10 to that number to find the base side on the second triangle. We can then use the equation "sin(21.04) = x/30" to find the missing length side (21.04 is the degree measurement).

Hope this helps :)
