Answer:
7-E -4
Step-by-step explanation:
My school supplyes us with a calculator and lucky for you it does scientific notation
You know that a straight line has an angle of 180 degrees;
48+x+x=180 <-- since they are all on the same time
48+2x=180
2x=180-48
2x=132
x=132/2
x=66
Therefore, the x value is 66 degree.
Hope I helped :)
Answer:
Sequence: 13, 20, 27
Rule: Tn = 7n + 6
Step-by-step explanation:
The 3 other numbers that can form an arithmetic progression is 13, 20, 27...
The nth term of an arithmetic progression is expressed as;
Tn = a + (n-1)d
a is the first term = 13
n is the number of terms
d is the common difference = 20 - 13 = 27 - 20
d = 7
Substitute
Tn = 13 + (n-1)(7)
Tn = 13 + 7n - 7
Tn = 7n+13-7
Tn = 7n + 6
This gives the required rule
1) 50 × 2 = 100
2) 60×20= 1200
3) 70×20=1400
Hope this helps
Answer:
Step-by-step explanation:
if i am reading this correctly it would be y2-y1/ x2-x1
therefore substitution
-8-(-8)/7-3 this is a fraction
0/4= 0
