Answer:
a = 7
Step-by-step explanation:
3(1 - 2a) = -3a - 18
3 - 6a = - 3a - 18
Add 18 to each side:
3 + 18 - 6a = - 3a - 18 + 18
21 - 6a = - 3a
Add 6a to each side:
21 - 6a + 6a = - 3a + 6a
21 = 3a
3a = 21
Divide each side by 3:
3a ÷ 3 = 21 ÷ 3
a = 7
30 x 5/6 = 25
The answer is 25 people
I hope this helped. Let me know if you have any other questions!
Answer:
CD = 7
Step-by-step explanation:
Since D is on the line segment CE then
CE = CD + DE , substitute values
2x = x + 7 ( subtract x from both sides )
x = 7
Thus
CD = x = 7
Answer:
b,f
Step-by-step explanation:
b: if sandi scored 3 more points than randi, then sandis points are equal to 3+randi
f: so the equation is 3+r=s,
so input values
3+r=18
r=18-3
r=15
Answer:
D. (y+1)=5(x+2)
Step-by-step explanation:
Point-slope form follows: y - y1 = m(x - x1)
Since both x and y are negative for (-2,-1), it becomes a positive because two -'s become a +.
m(slope)=5
y-(-1)=5(x-(-2))
y+5=5(x+2)
