2.5 + 3 = 5.5 total speed
7miles / 5.5 mph = 1.27 hours
Add these together.
You get -15y=-45
So y=3
Now plug in to first equation.
8x-8(3)=-16
8x-24=-16
8x=8 so x=1
Check both values in second equation.
-8(1)-7(3)=
-8-21=-29
It works...so x=1, y=3
There are eight, if I'm understanding the question correctly. 8 is in the ten thousands place, at least
Answer:
D. 30.5
Step-by-step explanation:
Given that A, B, C, D, and E are collinear,
AE = 38,
BD = 15, since segment BC = CD = DE, therefore
BD = ⅔ of BE
15 = ⅔*BE (substitution)
Solve for BE
Multiply each side by 3
15*3 = ⅔*BE*3
45 = 2*BE
Divide both sides by 2
45/2 = BE
22.5 = BE
BE = 22.5
Find AB:
AB + BE = AE (segment addition postulate)
AB + 22.5 = 38 (Substitution)
AB = 38 - 22.5 (Subtracting 22.5 from each side)
AB = 15.5
Find length of segment AD:
AB + BD = AD (segment addition postulate)
15.5 + 15 = AD (Substitution)
30.5 = AD
AD = 30.5
Answer:
The total amount he will altogether be: $19360
Step-by-step explanation:
Given
- Amount Borrowed = P = $16,000
- Interest rate = r = 6% = 6/100 = 0.06
- Time period = t = 3.5 years
To determine
- Total Amount altogether = A
Using the formula
I = Prt
substituting the values P = 16,000, r = 0.06, t = 3.5 years
I = 16,000 × 0.06 × 3.5
I = $3360
Thus, the interest amount = $3360
Therefore, the total amount he will altogether:
A = P + I
A = 16,000 + 3360
A = $19360
Therefore, the total amount he will altogether be: $19360
