What is the value of x?

Mathematics
1 answer:
GrogVix [38]3 years ago
3 0

Answer:

9

Step-by-step explanation:

The two triangles \triangle MNP\sim \triangle RST.

Therefore the corresponding sides are proportional.

\frac{|ST|}{|PN|} =\frac{|TR|}{|MP|}

From the diagram |MP|=4, |PN|=3, |MN|=5 |ST|=x and |TR|=12.

Let us substitute the values and solve for x.

\frac{12}{4}=\frac{x}{3}

Multiply both sides by 3 to get:

3*\frac{12}{4}=\frac{x}{3}*3

This implies that:

9=x

Therefore x=9

What equation can be used?
Kryger [21]

Answer:

f(x)=89x+1800

Step-by-step explanation:

$1800 is spent on a washing machine. This number never changes, so we just need to add that to our annual total

$89 is spent every year. This means that this number needs to be with our variable, x, as it is dependent on the number of years that occur. When we put these two things together, we get the following equation:

f(x)=89x+1800
