Person = 1 head and 2 legs
 horse = 1 head and 4 legs

p +h = 74
p = 74-h

2p +4h = 196

2(74-h) +4h = 196

148-2h +4h = 196

148 +2h = 196
2h = 48

h = 48/2 = 24
 
 24 horses
50 people

answer is B

Franco and Marcia getting high speed Internet access at the same time. Francos provider charges $60 for installation and $42.95
In-s [12.5K]

Answer:

4 months

Step-by-step explanation:

Franco's provider = 60 + 42.95x

Marshal's provider = 57.95x

Where,

x = number of months

Equate both charges

Franco's provider = Marshal's provider

60 + 42.95x = 57.95x

Subtract 42.95x From both sides

60 + 42.95x - 42.95x = 57.95x - 42.95x

60 = 15x

Divide both sides by 15

60 / 15 = 15x / 15

4 = x

x = 4 Months

Franco and Marshal would have paid the same amount for high-speed Internet service after 4 months

How much would $100 invested at 8% intrest compounded annually be worth after 15 years? round your answer to the nearest cent. d
frosja888 [35]
Our P = 100, r = .08, n = 1 (annually means once a year), and t = 15.  Filling in accordingly, we have A(t)=100(1+ \frac{.08}{1})^{(1)(15)}.  Simplifying a bit gives us  A(t)=100(1+.08)^{15}  and  A(t)=100(1.08)^{15}.  Raising that number inside the parenthesis to the 15th power gives us  A(t)=100(3.172169114).  Multiplying to finish means that A(t) = $317.22

Find the vertex of an angle of an isosceles triangle if one base angle is 8 less than half the vertex?
skad [1K]
Vertex angle = x
1 base angle = 1/2x - 8

180-x = (1/2x-8)x2
180-x = x-16
196-x = x
196 = 2x
x=98

Check that 2b+b and 3b have the same value when b is 1,2, and 3. Do 2b+b and 3b have the same value for all values of b? Explain
Inessa [10]

Answer:

Expression 2b+b and 3b have same values for all values of b.

Step-by-step explanation:

Given the two expression 2b+b and 3b and values of b as 1, 2 and 3.

Consider first expression that is, 2b+b.

Substituting the value of b=1,

2\left(1\right)+\left(1\right)=2+1=3 ....1

Substituting the value of b=2,

2\left(2\right)+\left(2\right)=4+2=6 ....2

Substituting the value of b=3,

2\left(3\right)+\left(3\right)=6+3=9 ....3

Consider second expression that is, 3b.

Substituting the value of b=1,

3\left(1\right)=3 ....4

Substituting the value of b=2,

3\left(2\right)=6 ....5

Substituting the value of b=3,

3\left(3\right)=9 ....6

For value of b=1, equation 1 and equation 4 are same, for value of b=2, equation 2 and equation 5 are same and for value of b=3 equation 3 and equation 6 are same.

Therefore both expression are same for all values of b.
