Answer:

10.7a - 8.1b

Step-by-step explanation:

the simplest form of the expression (14.2a + 9.8b) - (13.1b - 0.2a) - (3.7a + 4.8b)

(14.2a + 9.8b) - (13.1b - 0.2a)- (3.7a + 4.8b)

To subtract the expressions we multiply negative sign inside the second parenthesis, change the sign of each term in second and third parenthesis

14.2a + 9.8b - 13.1b + 0.2a-3.7a-4.8b

Now we combine like terms

14.2a +0.2a-3.7a = 10.7a

9.8b - 13.1b-4.8b=-8.1b

So the expression becomes

10.7a - 8.1b

Answer:

1⅗

Step-by-step explanation:

=44/5÷11/2

=44/5×2/11

then 11 goes into forty-four. 4

therefore

=4/5×2/1

Bart used place value and the distributive property to rewrite the expression 6(412). His work is shown below. 6(412) = 6(400 +
egoroff_w [7]

Bart should;

Multiply 6(400), 6(10), and 6(2) ⇒ 2nd

Multiply each addend by 6 ⇒ 4th

Find the sum of (2400 + 60 + 12) ⇒ 5th

Step-by-step explanation:

Let us revise the distributive property

  • a(b + c) = ab + ac
  • a(b + c + d) = ab + ac + ad

Bart used place value and the distributive property to rewrite the

expression 6(412)

His work is shown 6(412) = 6(400 + 10 + 2)

We need to know what Bart should do to find the product

∵ 6(412) = 6(400 + 10 + 2)

- Multiply each number in the bracket by 6 in the right hand side

∴ 6(400 + 10 + 2) = (6)(400) + (6)(10) + 6(2)

∴ 6(400 + 10 + 2) = 2400 + 60 + 12

∴ He should to multiply each addend by 6 and then find the sum of

  (2400 + 60 + 12)

Bart should;

Multiply 6(400), 6(10), and 6(2)

Multiply each addend by 6

Find the sum of (2400 + 60 + 12)
