Let's solve your equation step-by-step.5.4=a−(−1.8)Step 1: Simplify both sides of the equation.5.4=a+1.8Step 2: Flip the equation.a+1.8=5.4Step 3: Subtract 1.8 from both sides.a+1.8−1.8=5.4−1.8a=3.6

Subtracting a negative cancels them to become positve so now we have a + 1.8 = 5.4.

subtract 1.8 from both sides of a + 1.8 = 5.4 to isolate the variable and we have:
a = 3.6 because 5.4 - 1.8 is 3.6.

therefore a = 3.6. hope this helped! plug it into the original equation and you see that you get 5.4 = 5.4

2. x + 10

3. -4d + 15

4. true, associative property

5. distributive, commutative

Step-by-step explanation:

1. distribute 3/4 into the parentheses, so multiply 3/4 * 8 and 3/4 * -20

2. distribute the 2 into the parentheses so multiply 2 * 3x and 2 * 5, then combine like terms

3. distribute -3 into the parentheses so -3 * 4D and -3 * -5 then add like terms

4. add like terms on both sides of the equal sign and you get 10x on both sides. this is the associative property because it doesn't matter what's inside or outside the parentheses you get the same answer no matter how you add them up

5. the first part is distributive because you distributed the three into the parentheses and the second part is commutative because you switch them around and you can get the same answer
