Answer:
Step-by-step explanation:
So we have the equation:
First, distribute the 2 into the absolute value:
Definition of absolute value:
Left:
Subtract 2k from both sides:
Add 2 to both sides:
Right:
Distribute the negative:
Add 2k to both sides:
Add 2:
Divide by 5:
So, our solutions are:
Answer:
(4 , -8) Due to the x / y axis. And (-4 , -2)
Step-by-step explanation:
Answer:
x=28
Step-by-step explanation:
180-42=138 since a triangle adds up to 180
2x+10+3x-12=138 then combine like terms
5x-2=138 add 2 to both sides
5x=140 divide each side by 5
x=28
Answer:
a) ( j + m ) / 7
b) The product of <em>j</em> and <em>m </em>increased by 7
Step-by-step explanation:
Answer:
m<B: 56
Step-by-step explanation:
All triangles add up to 180
<B = x
x + 34 + 90 = 180
x + 124 = 180
x = 56
