Question

What is the answer’s

Answer 1

1. 3(5q+9)+5q

4(5q+6)

use number 3 for q

3(5*3)+9+(5*3)

3*15+9+15

45+24

69

4(5*3)+6

4*15+6

60+6

66

the first expression represents a number greater than the second expression

69>66

2. -4(7-2m)+11m

first we do -4*7 and -7*-2

(-28+8m)+11m

8m+11m is 19m

(-28)+19m

3. -18- 1/2(50z+60)-35z

6(-12-10z+4)

12(-5z-4)

first expression:

-18 - (25z+30)-35z

-18 - -10z+30

-18+10z+30

12+10z

second expression:

6(-8-10z)

-48-60z

third expression:

-60z-48

the first expression is not equivalent to the third expression, but the second expression is
