x = 15
Step-by-step explanation:
20^2 + x^2 = 25^2
400 + x^2 = 625
subtract each side 400
it results to 225
square root 225, to equals this -->
X = 15
Answer:
Equation: 3(1.25) + 3(2.00)=M
answer:9.75
Step-by-step explanation:
I used R for Rick since I am putting everything in Rick's case. The equation would be (R+10)+(R-8)+(R-11)=315.
Once you add the same terms you end with 4R-9=315
You add 9 to both sides
4R=324
Then divide
R=81
For Don, since his is ten point higher, his would be 91.
Rick is 81.
Jackie would be 73 since it is 8 points less.
And Jared would be 70 since it is 3 point less.
Check by adding; 81+91+73+70=315
