Answer:
Lisa is not right.
Step-by-step explanation:
The equation Lisa is solving is x+6=8+x
The solution for the given value will be the value of x.
To solve for x we isolate the x term that is bring both x on one side of the equal sign.
Subtracting x both sides we have:
x-x+6=8+x-x
The x on both sides gets cancel and hence there is no value of x that will satisfy the equation x+6=8+x.
So Lisa solution is not right.
x = Kevin
y = Steve
Kevin: x = y+4
x+y = 26
y+4+y = 26
2y +4 =26
2y = 22
y = 22/2 =11
Steve ran 11 miles
Kevin ran 11+4 = 15 miles
15+11 = 26
Solve for w by simplifying both sides of the equation by isolating the variable then combining like terms w= -3
Answer:
Let x = the measure of the smaller angle
Let 3x + 40 = the measure of the larger angle
x + 3x + 40 = 180
4x = 140
x = 35º
3x + 40 = 3(35) + 40 = 145º
