In this question, you're solving for x.
Solve for x:
x + 4.2 = 7
You need to get x by itself, to do so, you would need to subtract 4.2 from both sides:
x = 2.8
Answer:
x = 2.8
Only one, if you want to know the measurement of the other side use the cosine law and to know the other angles use the sine law :)
Answer:
the slope is -1/4
Step-by-step explanation:
the change in y over the change in x from point (-2,-2) to (2,-3) is how to find the slope
y1-y2/x1-x2 = m
-2--3/-2-2 = -1/4
Its 30 you find the unit rate by 21÷7 which equals 3 then you multipy 3x10 which gives you 30
