Answer: See explanation
Step-by-step explanation:
Your question isn't really clear but let me help.
For Maths test,
Point earned = 30
Total point = 43
Percentage = 30/43 × 100 = 69.77%
Social studies test
Point earned = 85.
Total point = 124
Percentage = 85/124 × 100 = 68.55%
From the above, we can see that Jake scored a higher percentage in the Maths test.
Answer:
Step-by-step explanation:
5x+20 = 0
5X= -20
X= -20/5 = -4
8(4n+3) = 32n+24 =0
32n = -24
n = -24/32 = -3/4
12n-6=0
12n =6
n = 6/12 = 1/2
9(2x+9)
18x+81 =0
18x= -81
x= -81/18 = -9/2= -4.5
36+9y=0
36=-9y
36/-9 = y = -4
7(n-3) = 0
7n-21=0
7n = 21
n = 21/7
n=3
21+15a = 0
21= -15a
a= 21/-15 = 7/-5 = -1.4
32x-12x=0
20x=0
x=0/20 = 0
n-4-9=0
n-13=0
n=13
-3x-9+15x=0
-3x+15x-9 =0
12x-9=0
12x=9
x=9/12 = 3/4 = 0.75

n = 45/-45 =-1
-5n+3(6+7n)
-5n+18+21n=0
-5n+21n+18 =0
16n+18 =0
16n = -18
n = -18/16 = -9/8 = -1.125
-4+7(1-3n)=0
-4+7-21n=0
3-21n=0
3=21n
3/21=n = 1/7
3n-(2n-8)
3n-2n+8=0
n+8=0
n=-8
Answer:
$860
Step-by-step explanation:
21.50 times 8 = 172
172 times 5 = 860

Answer:
a.Converge
b.Diverge
Step-by-step explanation:
We are given that
Because 
Hence, sequence An converges to 
when n tends to infinity or - infinity.
=diverges
Necessary condition for a series to converge :
when n tends to infinity .
But 
tends to when n tends to infinity.
Therefore, given series is divergent.
