Answer:
∠CED = 48°
Step-by-step explanation:
By adding all angles together, they’ll eventually equal ∠AED. Hence, sum of all given angles = ∠AED
∠AEB + ∠BEC + ∠CED = ∠AED
29°+12°+x = 89°
Solve for x and we will get measure of ∠CED:
41°+x = 89°
x = 89°-41°
x = 48°
Therefore, the measure of ∠CED is 48°
Answer:
5%
Step-by-step explanation:
The equation for simple interest rate is as follows:
A = P(1+rt)
A = final amount
P = initial principal amount
r = annual interest rate
t = time (in years)
So, we need to plug everything in and solve for r:
The final amount is equal to $875 plus the interest of $131.50.
A = 875 + 131.50 = 1006.50
Now, plug everything in:
1006.50 = 875( 1 + r(3))
Solve:
1 + 3r = 1.15028571 Divide 1006.50 by 875
3r = 0.15028571 Subtract 1 from 1.15028571
r = 0.050 Divide by 3
The simple interest rate would be 5%. I converted the r to a percent by multiplying 0.050 by 100.
I hope this helps!! Ask questions if you need!!
The first one
is (2,4)
5. is infinitely many solutions
because yu have tovhange the terms plces
-243=-9(10+x)
-243=-90-9x
+90 +90
-153=-9x _______________ divide -9 on both sides
x=17
