What two numbers have a sum of 215 and a difference of 137

BabaBlast [244]

Answer:

see below

Step-by-step explanation:

let x = big number

let you = small number

x + y = 215-------> (1)

x - y = 137 ------>(2)

(1)

x = 215 - y ----->(1)

substitute 1 into 2

215 - y -y = 137

-2 y = 78

y = 39

substitute y = 39 into (1)

x = 215 - (39)

x = 176

thus the numbers are 176 & 39

Answer:

Use this formula for these kinda things.

Step-by-step explanation:

Remember The z is the hypathonous, it means the biggest side.

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

where Z is going to be C

put this all together

${7}^{2} + {18}^{2} = {z}^{2}$

put it into calculator, means 373=

${z}^{2}$

therfore take the square root, it will be

$z = \sqrt{373}$

which it will be 19.31
