Answer:
25
Step-by-step explanation:
Right angled triangle
Solve for hypotenuse
This is the formula <em>c=√(a^2+b^2)</em> so pug in the numbers a=24 b=7 √(24^2 + 7^2)=c=25
Answer:
Step-by-step explanation:
Using substitution method.
y = 3x - 8 -------(i)
y = 4 - x -------- (ii)
Substitute y = 3x-8 in equation (ii)
3x - 8= 4 - x {Add x to both sides}
3x - 8 + x = 4 - x +x
4x - 8 = 4 {Add 8 to both sides}
4x = 4 + 8
4x = 12 {Divide both sides by 4}
x = 12/4
x = 3
Substitute x = 3 in Equation (i)
y = 3*3 - 8
y = 9 - 8
y = 1
