Answer:
x=-5
Step-by-step explanation:
When finding x, we basically have to isolate the variable. By isolating the variable, usually doing the opposite operation helps it.
Addition is the opposite of Subtraction
Multiplication is the opposite of Division
Let's dive into this problem!
x+7=2
(we need to isolate x. basically we need to get rid of this 7. How do we do this? since it is added by seven, we can subtract it by both sides to get rid of it on the x side.)
x+7=2
-7 -7
x=-5
(subtract 2-(-5), this adds to -5)
This is your final answer.
Answer:
-3/17
Step-by-step explanation:
(7,1) and (-10,4)
slope formula: m = (y₂ - y₁) / (x₂ - x₁)
plug in data: m = (4 - 1) / (-10 - 7)
solve: 3 / -17
simplify: -3/17 (written as a fraction)
Answer:
9.2
Step-by-step explanation:
Use law of sines
a/sinA = b/sinB
5/sin 31 = b/sin 108
b=9.2
Answer:
17b - 2
Step-by-step explanation:
5b - 5 - 12b - 7
Say bye to the 12b, and add 12 to it and the 5.
5b + 12 = 17b
17b - 5 - 7
Add 5 to the 5 and the -7.
-7 + 5 = -2.
Now you have 17b - 2. You can’t go farther, so there’s your answer.
