Answer:

A (I carefully did it)

Step-by-step explanation:

This is a really easy algebra question tho

1. Step 1 -> Step 2 is wrong

2. Step 1:

$0.2(4+1.4y-2.1)=0.8+0.28y-0.42$

3. But Step 2:

$0.2(4+1.4y-2.1)\neq 4.2+1.6y-1.9$

4. She added 0.2 to each term instead of multiplying by 0.2

Find the sum.

You are gonna use the distributive property.

4(2.5g - 4) + 3(1.2g - 2)

So you are going to multiply 4 with everything inside the first set of parenthesis and your gonna multiply 3 with everything insides the second set of parenthesis.

4 x 2.5g - 4 x 4 + 3 x 1.2g - 3 x 2

10g - 16 + 3.6g - 6

You wanna combine like terms:

10 - 3.6g + 16 - 6

6.4g + 10

You answer is 6.4g + 10.

Hope this Helps!!

Following PEMDAS is crucial to solving these. Please Excuse My Dear Aunt Sally

P - Parenthesis

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

Multiplication/Division and Addition/Subtraction are interchangeable.

Now then, number 1 has the following:

$4-2*409-8*96$

There are no parenthesis or exponents, but there is multiplication, so we will start with multiplying. There are two multiplication expressions in the problem.

$-2 * 409 = -818$
