Answer:
slader app helps alot
Step-by-step explanation:
total of ages now is 67 + 4 + 4 = 75
S=shelly
M= Michelle
Michelle is 3 yrs younger than Shelly so use S-3
S +M = 75
replace M with S-3 to get:
S +S-3=75
2S=78
s=39
So shelly is 39
Michelle is 3 years younger = 39-3 = 36
For this problem, we can say that corresponding angles are congruent, or the same, this also means that their angle measures have to be the same. Then, our equations for our angles will be vertical angles, which means that they must equal each other. So we would then write our equation as 3x+20=4x+10 or 4x+10=3x+20. Then, to combine like terms, we will subtract 3x from both sides, resulting in x+10=20. Then we will subtract 10 from both sides, resulting in x=10.
Answer:
8n/9 - 4/3
Step-by-step explanation:
On this part, you can use the formula for compound interest:
F = P(1+i)^n
F = future worth of $
P = present worth of $
i=interest
n=years
F = 2700(1+0.03)^1
F = 2781
<span>So interest = 2781-2700 = $81
