Taylor is building dog houses to sell. Each doghouse house requires free full sheets of plywood which Taylor cuts into new shapes. The plywood is shipped in bundles of 14 full sheets. How many dog houses can tell him make from 12 bundles plywood.

Answers

Answer: 168

Step-by-step explanation:

Given : Taylor is building dog houses to sell. Each doghouse house requires free full sheets of plywood which Taylor cuts into new shapes.

The plywood is shipped in bundles of 14 full sheets.

Then , the number of dog houses can tell him make from 12 bundles plywood :-

$12*14=168$

Hence, the number of dog houses can tell him make from 12 bundles plywood = 168

The answer is 168 is the number of sheets are in 12 bundles of plywood

Maria bought seven boxes. A week later half of her boxes were destroyed in a fire. There are only 22 boxes left. With how many did she start?

Answers

The equation is (x+7)/2=22

X is what we need to find out. (I’m not sure if you are in algebra yet so I’m sorry if you’re not)

First we should give both sides the same denominator (22=22/1)

(X+7)/2=22/1 now we can change 22/1 to 44/2
(X+7)/2=44/2

Now since we are trying to find x, we can remove the denominator to solve for x and make it easier.

x+7=44 subtract 7 from both sides
x=37

***so your answer is 37***

Bert's cab company charges $1.00 plus an additional $3.00 per mile for a ride.Madeline,s cabs company charges $3.00 plus an additional $2.00 per mile fora ride. Write a system of linear equations that shows the cost in dollars,y, for a cab ride of x miles for each cab driver.

Answers

So our y value is the end cost, while our x value is the number of miles driven. Let's also add two variables, r and c. r stands for the rate, or the cost per mile, and c stands for the defined cost. So our function is y = rx + c. Remember that whenever we have a function, the y is replaced with f(x). No worries, they mean the same thing.So let's add the values into each variable for both companies. Bert's company would have a function of f(x) = $3x + $1, and Madeline's company would have f(x) = $2x + $3. So let's say you drove 5 miles in a cab from both companies. x would become 5, so put that into both functions. 3 times 5 plus 1 would end up being $16, so Bert's company costs $16 for a 5 mile drive. 2 times 5 plus 3 would end up being $13, so Madeline's company costs $13 for a 5 mile drive.

Rose lives 3/4 of a mile from her cousin. One day she rode her bike to her cousin's house. When she got 2/5 of the way there, her bike chain broke and she had to walk the rest of the way. What part of a mile did Rose go on her bike before it broke?

Answers

Answer: 3/10 of a mile

Step-by-step explanation:

Hi, to answer this question we simply have to multiply the 2/5 of the way that she travelled on her bike before it broke by the total distance (3/4 of a mile)

2/5 x 3/4 = 3/10 of a mile

She travelled 3/10 of a mile on her bike before it broke
