Question

Determine the value for x in the equation x over 5 and 7 tenths equals 2 and 3 tenths.

3.4
8.0
11.4
13.11

Answer 1

d. 11.4, 3.4

Step-by-step explanation:

Given

Required

Determine the zeros

The best way to solve this is to apply the graphical method.

First, we plot the graph of:

See attachment

Next, we write out all values of x when the line crosses the y-axis.

From the attached graph, the points are (approximately):

Option (d) is the closest to the above values.

Hence, the zeros are: -1.4 and 3.4

Answer 2

13.11

Step-by-step explanation:

`(x)/(5(7)/(10) )` = 2
`(3)/(10)` ( multiply both sides by 5
`(7)/(10)` to clear the fraction

x = 5
`(7)/(10)` × 2
`(3)/(10)` = 5.7 × 2.3 = 13.11
