Answer:
20.5 : 61.5
Step-by-step explanation:
1:3
1 + 3 = 4
82 ÷ 4 = 20.5
ratio of 1:3
1 × 20.5 = 20.5
3 × 20.5 = 61.5
20.5 : 61.5
This is a geometric sequence with first term a1 = -4 and common ratio r = 4
so nth term = a1* r^(n-1)
= -4 *4^(n-1)
Answer:
The solution of the inequality is x ≤ -4. A graph of the solution should have a vertical line passing through x = -4 and be shaded to the left of x = -4
Step-by-step explanation:
-7x + 13 ≥ 41
Subtract 13 from both sides
-7x ≥ 28
Dividing both sides by the -7 changes the inequality sign and we have
x ≤ -4
Hence, the solution of the inequality is x ≤ -4 and the graph of the solution should have a vertical line passing through x = -4 and it should be shaded to the left of x = -4 indicating that only numbers less than or equal to -4 are possible solutions of the inequality.
Hope this Helps!!!
Answer:
Step-by-step explanation:
a°=180°-36°=144° b°=180°-113°=67°
a°=144° and b°=67°
144+67=211
36+113=149
149+211=360
The answer is 25 which is by multiplying 4/10 and 5/x and the devide by 4
