Answer:
X-y=3. 2x-2y=6. 2y=-2
Y= -1
2x-4y=8. 2x-4y=8 2.x-4.-1=8
2x=4. x=2
Step-by-step explanation:
The answer is 6 because 4+1=5+1=6
9x-6-13x=94
-4x-6=94
-4x=100
x= -25
Answer:
d. 6
Step-by-step explanation:
Answer:
∠B
7(13)-1=90˚
Step-by-step explanation:
Are you saying ∠ABC or ABC as sides?
1. ∠ABC
(7x-1)+(4x+1)+(3x-2)=180˚
14x-2=180˚
14x=182
x=182/14
x=13˚
2. plug in
∠A
4(13)+1=53˚
∠B
7(13)-1=90˚
∠C
3(13)-2=37˚
