Answer:

the Pythagorean theorem is

a ^{2}  + b {}^{2}  = c {}^{2}

so plug in the numbers

a ^{2}  + 17 {}^{2}  = 15 {}^{2}

then square each of the known numbers to get

a {}^{2}  + 289 = 225

subtract 289 from 225 to get -64

then you are left with

a {}^{2}  =  - 64

then take the square root of -64

to get -8

Answer:

a^2 = c^2 - b^2

to get A though you need to take the square root.

Step-by-step explanation:

you need to rearrange the formula to get a by itself.

c^2 = a^2 + b^2

a^2 = c^2 - b^2

to get A though you need to take the square root.

At the city museum, child admission is $5.60 and adult admission is $9.30. On Sunday, 141 tickets were sold for a total sales of
IrinaK [193]

x = child tickets

y = adult tickets

x + y = 141

5.60x + 9.30y = 974.60

y = 141 - x

5.60x + 9.30 ( 141 - x ) = 974.60

5.60x + 1311.3 - 9.30x = 974.60

-3.70x + 1311.3 = 974.60

-3.70x = 974.60 - 1311.3

-3.70x = -336.7

x = 91

91 child tickets were sold that day
