I think you have multiply 5x4 which equals 20 then 20 divided by 10 which equals 2 and that’s ur answer
Answer:
<h2>22 hours and 10 hours </h2>
Step-by-step explanation:
let the jobs be x and y, so that
x+y=32--------1
9x+7y=248----2
x=32-y
substitute x=32-y for x in equation 2 we have
9(32-y)+7y=248
open bracket we have
288-9y+7y=248
-2y=248-288
-2y=-40
2y=40
divide both sides by 2 we have
y=40/2
y= 10 hours
subtitute y=10 for y in equation 1 to find x
x+10=32--------1
x=32-10
x=22
x=22 hours

![\sqrt32](https://tex.z-dn.net/?f=%5Csqrt32)
Step-by-step explanation:
You use the Pythagorean theorem since a triangle is formed.
![a^{2} +b^{2} =c^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2Bb%5E%7B2%7D%20%3Dc%5E%7B2%7D)
![6^{2} = 2^{2} +x^{2}](https://tex.z-dn.net/?f=6%5E%7B2%7D%20%3D%202%5E%7B2%7D%20%2Bx%5E%7B2%7D)
36-4 =![x^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D)
x= ![\sqrt{32}](https://tex.z-dn.net/?f=%5Csqrt%7B32%7D)
