Step-by-step explanation:
A. place a closed circle on -4 and shade to the right.
Answer:
m1 = 68°
m2 = 53°
m3 = 127
m4 = 31°
Step-by-step explanation:
m1 = 90-22
m2 = 68+59=127, 180-127
m3 = 180 - 53
m4 = 127+22=149, 180-149
Answer:
1. 6
2. 2
Step-by-step explanation:
1. 9-t=3(t-5)
9-t=3t-15
+t +t
9=4t-15
+15 +15
<u>24</u>=<u>4t</u>
4 4
6=t
2.5(5y+1)=10y-25
25y+5=10y-25
+25 +25
25y+30=10y
-25 -25
<u>30</u>=<u>-15y</u>
15 15
2=y
