Answer:
m∠K = 97°
Step-by-step explanation:
The sum of the measures of the angles of a quadrilateral is 360
127 + 5x + 3 + 10x + 7 + 88 = 360
15x + 225 = 360
15x = 135
x = 9
m∠K = 10x + 7 = 10(9) + 7 = 90 + 7 = 97°
Answer:
A
Step-by-step explanation:
1. y+5=-x-5
2. y=-x-5-5
3.y=-x-10
4. y=x-10
_______________________
1. distribute negative sign
2. move the constant to the right and change the sign
3. -5-5 equals -10, bring everything down
4. change the sign of the x to positive, the equation is in standard form
The statements that aer true or not or whatever
hmm, let's try te sencnarios
remember the commutative property of multiplication
ab=ba
so
what if they are both negative?
well, the negatives would cancel to leave with positive
the oposite would be both positive resulting in a positive
if they are differnt signs then result is negative
oposite would be still different signs so still negative
true statment
