A taxi service charges an initial $5 fee , plus $2 per mile driven.

arlik [135]

Part A answer: 2x+5. x is the number of miles driven.

Part B answer: $305. Plug in 150 for x, and the equation is 2*150+5=x, x being your answer that you are looking for. Do the Order of Operations, which is PEMDAS (Parenthesis, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right.) So in other words, do 2*150 first, and you get 300. Now your equation is 300+5=x. Add 300+5, and you get 305=x. So your answer is $305.

A male punky fish has 9 stripes and a female punky fish has 8 stripes.I count 86 stripes on the fish in my tank.What is the rati

Andrews [41]

The ratio of male fishes to female fishes is 3 : 2

Solution:

Given, male punky fish = 9 stripes

Female punky fish = 8 stripes.

Total stripes = 86

Finding the ratio of male fish to female fish:

Let the number of male fishes be "m", and the number of female fishes be "n"

The, given that, total strips = 86

which means, total male strips + total female stripes = 86

$\text { 9 stripes per male } \times \text { number of male fishes }+8 \text { stripes for female } \times \text { number of female fishes }=86$

$\begin{array}{l}{\rightarrow 9 \times m+8 \times n=86} \\\\ {\rightarrow 9 m+8 n=86}\end{array}$

The only values that can satisfy above equation are m = 6 and n = 4

Now, ratio of male fishes to female fishes = m : n = 6 : 4 = 3 : 2

Hence, the ratio of male fishes to female fishes is found out as 3 : 2
