3(4a+7)=5(2a+4)+1 What is it?
hichkok12 [17]

Answer:

a = 0

Step-by-step explanation:

3(4a+7)=5(2a+4)+1     Distribute 3 through the parentheses

                 - >                         12a + 21 = 5(2a + 4) +1

5(2a + 4) +1   -->  10a + 20 + 1

12a + 21 = 10a + 20 + 1  -->    12a + 21 = 10a + 21   -->      12a = 10a

                                                     12a - 10a = 0   -->    2a = 0

Divide both sides of the equation by 2      -->     a = 0

How can i identify a slope
Nonamiya [84]

Answer:

Rise over Run.

Step-by-step explanation:

If it's on a line on a graph you count how many it goes up until it's aligned with the next point and then you count how ever many over until it hits it. So it could be 2 up and 4 over making the slope 2/4.

I'm sorry that might not make much sense I'm bad at explaining but let me know if that helps at all!!

In the diagram below, ABC~ DEC. What is the value of x?
pishuonlain [190]

The value of x will be 3

From given diagram, triangle ABC and EDC meet at a common vertex C.

So, triangle ABC and EDC both are congruent to each other.

Applying the similarity property of congruence, ratio of the congruent triangles' corresponding sides will be equal.

Therefore,

\frac{AB}{ED} = \frac{AC}{EC} = \frac{BC}{CD}

\frac{AC}{EC} = \frac{BC}{CD}

Simplifying the expression,

We get

(18-x)/x = 25/5

(18-x)/x = 5

18-x = 5x

18-x-5x = 0

18 - 6x = 0

- 6x = -18

x = 3

Hence, the value of x is 3.
