Answer:
X=55° Y=35°
Step-by-step explanation:
X+Y=90°
Y= x-20
(X-20)+X=90°
2X-20=90°
2X=110°
X=55°
55°+Y=90°
Y=35°
Answer:
240+30x
Step-by-step explanation:
240+30x because you multiply 30 x 8 and get 240 plus 30 x X and get 30x
We have a proportion: 60/?= 20/100
Cross multiply:
20*?= 60*100
⇒ ?= 60*100/20= 300
60 minutes is 20% of 300 minutes~
Substitute the values given to you into the equation:
x-(y+z)
x=9
y=3
z=2
9-(3+2)
the answer is A.
X-intercepts: (3,0),(1,0)
Y-intercept: (0,3)
