Answer:
76
Step-by-step explanation:
(88+72+44+x)/4=70
88+72+44+x=280
204+x=280
x=76
Therefore, Tammy needs to score a 76 on her last test to get at least an average of 70.
X = y + 11
2x + y = -2
2(y + 11) + y = -2
2y + 22 + y = -2
3y + 22 = -2
3y = -24
y = -8
x = y + 11
x = -8 + 11
x = 3
Solution set {3, -8} (C)
3/4
You can divide both of them by 4. 12/4= 3 and 16/4= 4 Youre welcome
Y is same as the missing angle, the triangle need to equal to 180 so if you add 20 to 60 it equal to 80
use 180 to subtract to 80 you will get the missing x, x=80
1. The number '2' is located in the tens place
2. Since the number '3' is located in the ones place, it's telling the number '2' to stay the same
Stays the Same: 1,2,3,4
Goes Up: 5,6,7,8,etc
223 ⇒ 220
