isos triangle means 2 sides are =
Ignore the image most images are not to scale
one angle is 75 so another is 75. 75*2 =150
180-150 =30
3d + 8 = 2d - 7 equals d = -15.
First, subtract 2d from both sides. Your problem should look like: 3d + 8 - 2d = -7.
Second, simplify 3d + 8 - 2d to get d + 8. Your problem should look like: d + 8 = -7.
Third, subtract 8 from both sides. Your problem should look like: d = -7 - 8.
Fourth, simplify -7 - 8 to get -15. Your problem should look like: d = -15, which is your answer.
Hopefully this helps, I'm not exactly sure what you meant by "is equations," but this is how you solve the problem.
I think it is D the answer choose
ANSWER:
Reserve rate = 1.03%
Step by step explanation:
Initial amount = $6000
Total sum = $2,00,000
A G.P(geometric progresssion) series is formed with initial value = 6000
Since the depositing cycle continues infinitely, therefore the sum of G.P formula will be taken for infinite values
S= a\1-r
where s= 2,00,000 (sum)
a=6000 (initial amount)
r= ratio (reserve rate)
2,00,000= 6000\1-r
r = 1.03 %
