Answer:
x = 3
y = 1
Step-by-step explanation:
9x - y = 26 ---------------(I)
9x + y = 28 ---------------(II)
9x - y = 26
9x = 26 + y
Substitute 9x = 26 + y in equation (II)
26 + y + y = 28 {add like terms}
26 + 2y = 28 {subtract 26 from both sides}
2y = 28 - 26
2y = 2 {divide both sides by 2}
y = 2/2
y = 1
Substitute y =1 in equation (I)
9x - 1 = 26
9x = 26 + 1
9x = 27
x = 27/9
x = 3
x = 3
y = 1
To do 130% increase you multiply by 1.3 so you do 810 × 1.3 = 1053
Answer:
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
In order for there to be a right triangle formed, this must satisfy pythagoran's theorm thingy:
a^2+b^2=c^2
7^2+15^2=274
22^2= 484
since 274 isnt equal to 484
There is not a right triangle formed here
