PLS PLS HELP! I need the answer ASAP
Nat2105 [25]

Answer:

E

Step-by-step explanation:

-x +6 ≥  -3x - 4

Add 3x to both sides

-x + 3x + 6 ≥ -4

Combine like terms

2x + 6 ≥ -4

Subtract 6 from both side

2x ≥ -4 - 6

2x≥ -10

Divide both sides by 2

x ≥ -10/2

x ≥ -5

PLEASE SIMPLIFY THESE
Pavel [41]

Answer:

a. 0.69x + 0.14

b. 5.67 - 30.48a

c. 1.1x - 3.01y

Step-by-step explanation:

a) 2.56x + 0.14 − 1.87x

<em>To simplify this algebraic expression, you start by collecting like terms;</em>

2.56x − 1.87x  + 0.14

<em>Then perform arithmetic operation</em>

0.69x + 0.14

b) 7.32a + 2.1 (2.7 − 18a)

<em>Here; first, the bracket must be opened</em>

<em>To open the bracket; each expression in the bracket is multiplied by 2.1. This leaves us with</em>

7.32a + 2.1 * 2.7 − 2.1 * 18a

7.32a + 5.67 - 37.8a

<em>Then, you collect like terms</em>

7.32a - 37.8a + 5.67

<em>Then perform arithmetic operation</em>

-30.48a + 5.67

<em>Rearrange</em>

5.67 - 30.48a

c) 0.12x + 0.34y + 0.98x − 3.35y

<em>Here, you start by collecting like terms</em>

0.12x + 0.98x + 0.34y − 3.35y

<em>Then perform arithmetic operation</em>

1.1x - 3.01y
