Answer: x = 2/7y + 3/7 and

x= -5/4y + 0.8125

Step-by-step explanation: Let's solve for x.

7x−2y=3

Step 1: Add 2y to both sides.

7x − 2y + 2y= 3 + 2y

7x = 2y + 3

Step 2: Divide both sides by 7.

7x/7 = 2y+3/7 this is for the second answer Step 1: Add -5y to both sides.

4x+5y+−5y=3.25+−5y

4x=−5y+3.25

Step 2: Divide both sides by

4/4 x 4 = −5y + 3.25/4

Given the following triangle, if b = 9 and B = 15°, find a.

NeX [460]

The picture in the attached figure

we know that
Applying the law of sines
b/sin B=a/sin A------> a=b*sin A/sin B
b=9
B=15°
A=180-(90+15)-----> A=75°
a=?
a=b*sin A/sin B-----> a=9*sin 75/sin 15----> a=33.59 units

the answer is
33.59 units

Goshia [24]

Dear Joshua10, the answer is 36. 36 is two digits, 3 and 2, it is a multiple of 6 and 12: 6 times 6 equals 36 and 12 times 3 equals 36, it is a factor of 108: 36 times 3 equals 108, and 36 has digits that equal to 9: 3 plus 6 equals 9.
