Question

Evaluate the expression
1) (-11-6- -5 +1+3 x2)➗-5

Evaluate each using the value given.
1) z➗6+x+x-5; use x=1, and z=6
2) x(z+3)+1+3-y; use x=6, y=-5 and z=2
3) 6+q+5-(q-p)+15; use p=1, and q=1
4) -3➗3(a+c(b+5)-(-6+a)); use a=1, b=-6, and c=-4

Simplify each expression.
1) 9x+9-1
2)-9-6(v+5)
3) 1+4(2-3k)
4) 7(1+9v)-8(-5v-6)
5) -2(-6x-9)-4(x+9)
6) 10n-4n
7)-10(-8x+9)-8x
8)-8v+6(10+6v)
9)-10(x-7)-7(x+2)
10) 9(7k+8) + 3(k-10)
