C. 10
14x+14x+(3x+10)+(3x+10)=
34x+20=360=
X=10
Answer:
185 Points
Step-by-step explanation:
38 x 2 = 76
33 x 3 = 99
8 x 1 = 8
78 + 99 + 8 = 185
16. LCD: 48 because 1/4= 12/48, 1/12=4/48, 11/16= 33/48 and they all share 48 as the denominator
17. LCD: 168 because 5/56= 15/168, 7/24= 49/168, 7/12= 98/168, 5/42= 20/168
18. LCD: 30 because 2/1= 60/30, 1/5= 6/30, 1/10= 3/30, 5/6= 25/30
8 a.m. to 1 p.m. = 5 hrs
so the temperature changed -3/5 degrees per hr for 5 hrs...
-3/5 * 5 = -15/5 = -3.....so in total, the temperature changed by 3 degrees....it went down 3 degrees
(-4,-4)(1,3)
slope = (3 - (-4) / (1 - (-4)
slope = (3 + 4) / (1 + 4) = 7/5
y - y1 = m(x - x1)...using (-4,-4)
slope(m) = 7/5
y - (-4) = 7/5(x - (-4) =
y + 4 = 7/5(x + 4) <==here is one
y - y1 = m(x - x1)..using (1,3)
slope = 7/5
y - 3 = 7/5(x - 1) <== here is the other one
