Joe has been given a treasure map on which he must plot three points. There is a portion of the treasure at each point. Point A is at (-4,0), Point B is at (-4,5), and Point C is at (4,2). If Joe has already found his at Point A, how far must he walk to get to Point B? I think it has something to do with a coordinate plane, I'm not sure.

Answers

yo has to find distance from A to B
since the x coordinate didn't move ( from -4 to -4) we find the distance the y moved
from 0 to 5 is 5 units

he has to walk 5 units

E is wrong. It only says twelve but it is a square and squares have the same side so u would really do twelve times twelve and get 144. And also I got 360 on the challenge one because u would split the irregular figure and you would do ten times nine equals ninety then nine times thirty equals 270. Then add it and you old get 360 m2

Mr. Hamm's salary has increased by 250% over the past 10 years. If his original salary was $28,000 per year, what is his current salary?

Answers

When you say this, I'm assuming he has gained this in total, not once a year:
2.50(28000) + 28000
We can make it simpler:
3.50(28000)
98000
Mr. Hamm now receives $98,000 a year

Answer:

98,000

In bowling, you get a spare when you knock down the ten pins in two throws. How many possible ways are there to get a spare?

Answers

9 ways are possible hope this helped straight and to the point not gonna go and show exactly how just trust me

Final answer:

In bowling, there are ten possible ways to get a spare. This involves knocking down a total of 10 pins in two throws, regardless of the number of pins knocked down in each throw.

Explanation:

In bowling, there are multiple ways to get a spare. A spare requires all ten pins to be knocked down, but it does not matter how many pins were knocked down in each throw, only that the total after two throws is ten. For example, you could knock down 9 pins in the first throw and 1 in the second, or 5 pins in both throws. Therefore, there are ten possible ways to get a spare, ranging from knocking down 1 pin on the first throw and 9 on the second, to knocking down 9 pins on the first throw and 1 on the second throw, and every combination in between.

How do you solve 4x-7=2x+15

Answers

The value of the solution of expression is, x = 11

We have to give that,

An expression to simplify,

4x - 7 = 2x + 15

Now, Simplify the expression by combining like terms as,

4x - 7 = 2x + 15

Subtract 2x on both sides,

4x - 2x - 7 = 15

2x - 7 = 15

Add 7 on both sides,

2x - 7 + 7 = 15 + 7

2x = 22

Divide 2 into both sides,

x= 22/2

x = 11

Therefore, the solution is, x = 11

Darcy, Jason and Maria share.$268. Jason has $20more than Darcy and Maria has twice as much money as Jason. How much money do Darcy and Jason have altogether?

Answers

$x-Jason's\ money\nx-20-Darcy's\ money\n2x-Maria's\ money\n\nx+x-20+2x=268\nx+x+2x=268+20\n4x=288\ \ \ \ \ \ \ |:4\nx=72\n\n72-20=52\n\n72+52=124\n\nDarcy\ and\ Jason\ has\ \$124\ alltogether$

Answer:

$124.

Jason- 20$ more than Darcy

Maria- Twice as much as Jason

Darcy- 20$ less than half of Maria's sum.

Step-by-step explanation:

After I had written the page below, I came back up here and realized there was a much easier way.

268/2 = 134

Since the 20 Is added after, half is subtracted and you end up with

124!!

Now for my explanation done first, typed and read as I figured it out.

First and mostly, we need to find what Darcy starts with.

Let's say that Darcy has 5 dollars, to start somewhere easy. That would mean that Jason has 25 dollars since he has 20 more than her. That would mean that Maria would have 50 dollars, and the looted sum is 80.

Since that is less than a quarter of our end goal of 268$, I raised Darcy's initial amount of money to 15 to triple her money.

Math revised here- 15+20= (35*2) 70= 120

15+35+70

Since that is too low, I'm adding it to 30$.

Math revised again here- 30+20=(50*2)=100= 180

30+50+100

5 15 30

80 120 180

That is a chart determining our answers so far. There is no clear pattern, so let us continue.

Darcy starts with 50 dollars for this one.

50+20=(70*2)=140

50+70+140
