Answer:

  d)  m∠a = m∠f

Step-by-step explanation:

Where a transversal crosses parallel lines, certain relationships between the angles are established. Effectively, the two same-side interior angles are supplementary, as they would be in a parallelogram. Here, those are angles B and F, or angles A and E.

The vertical- and linear-angle relationships give rise to all of the other ways this is expressed. For example, angles A and B are a linear pair, so supplementary. Since B and F are supplementary, and B and A are supplementary, F = A. Using more formal language, ...

  m∠a = m∠f

5. 40 = }(9x + 30) + 2
Anvisha [2.4K]

Answer:

x=-16

Step-by-step explanation:

We are given with the equation

40=-\frac{1}{3} \times (9x+30)+2

We are asked to solve it for x.

Distributing \frac{1}{3} over bracket and simplifying

40=-(\frac{9x}{3}+\frac{30}{3})+2

40=-(3x+10)+2

40=-3x-10+2

40=-3x-8

Adding 8 on both sides

48=-3x

Dividing both sides by -3

x=-16

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
