3x + 6 + x + 2 = 180
4x = 180 - 8
4x = 172
x = 43
A = 3x + 6 = 3×43 + 6 = 129 + 6 = 135
Answer:
it is voa
Step-by-step explanation:
45= 6r-3
45+3=6r
48=6r
r=8
Step-by-step explanation:
Sn= a+[n-1]d
S2= a+[2-1]d
8.5 = a+d _______Equation 1
S5 = a+[5-1]d
13=a+4d ________Equation 2
Subtract Equation 1 from Equation 2
13=a+4d
-
8.5= a+d
________
4.5= 3d
d=1.5
Substituting d=1.5 in equation 1
8.5=a+1.5
a=8.5-1.5
a=7
Sum of terms of an A.P =
Sn= n/2[2a+(n-1)d]
292= n/2[2×7+(n-1)d]
292=n/2[14+(n-1)1.5
292×2=n[14+(n-1)1.5]
584=n[14+1.5n-1.5]
584= 14n+1.5n²-1.5n
584= 1.5n²+12.5n
1.5n²+12.5n-584
1.5n²-24n+36.5n-584
1.5n(n-16)+36.5(n-16)
(1.5n+36.5)(n-16)
**n-16=0
n=16
Answer:
arthur is about 6 meters from Cameron, and Jamie is about 10 meters from Cameron so Jamie is closer to Cameron
Step-by-step explanation:
you go 4 to the right side than 6 up for Jamie
you go 6 to the right for arthur
Answer:
Find the equation of the line perpendicular to x = 0 that passes through (-3,1)
Step-by-step explanation:
Using the equation, y - y1 = m(x - x1)
Since x = 0, the gradient, m = 0
Hence, y - 1 = 0
∴ y = 1
