Question

Write answer with solution.
1. 6a+3; a = 5
2. 15a-24b+ 15; a = 4 and b=2
3. x+3(x-5); x=15
4. 50a(2-a); = 7

Answer 1

Answer:

1. 33   2. 27   3. 45   4. -1750

Step-by-step explanation:

6(5)+3=33

15(4)-24(2)+15=27

15+3(15-5)=45

4th, you get the idea, but is a=7?

Answer 2

Answer:

1) 33

2)27

3)45

4)-1750

Step-by-step explanation:

1. Given: a=5

6a+3

Substitute 'a' value

6(5)+3

=30+3

=33

2.Given: a = 4 and b=2

15a-24b+ 15

Substitute 'a' and 'b' value

15 (4)-24 (2)+15

=60-48+15

=27

3.Given: x=15

x+3(x-5)

Substitute 'x' value

15+3 (15-5)

=15+3 (10)

=15+30

=45

4.Given:a = 7

50a(2-a)

Substitute 'a' value

50 (7)(2-7)

=50(7)(-5)

=50 (-35)

= -1750
