Answer:

A few things:

"aboard" is misspelled- you wrote "abord"
"underwater"- looks like you wrote "undwater"
1,500- 15,00
you're missing the units in your final answers- 146lbs and 1325ft

Other than that, your exercises are well done and overall, your work looks really nice. I like your handwriting. :)

If the m = and the b = -2. then the linear equation is:

Leto [7]

Hey there! I'm happy to help!

The linear equation with m and b is called the slope intercept equation, where m is the slope and b is the y intercept. It is written as y=mx+b.

We see that m is equal to 1 and b is equal to -2. We can write this down as y=1x-2, or just y=x-2 as 1x is just x.

Have a wonderful day! :D

A collection of nickels and dimes has a value of 1.85. The value of the dimes is 0.10 less than twice the value of the nickels.

Alekssandra [29.7K]

Step-by-step explanation:

Let n be the number of nickels and d be number of dimes.

Since we know that the value of one dime equals $0.10 and value of 1 nickel is $0.05, therefore, value of n nickels will be 0.05n and value of d dimes will be 0.10d.

We have been given that a collection of nickels and dimes has a value of 1.85.

Let us represent this information in an equation.

$0.05n+0.10d=1.85...(1)$

We have been given that the value of the dimes is 0.10 less than twice the value of the nickels.

We can represent this information in an equation as:

$0.10d+0.10=2*(0.05n)...(2)$

Therefore, our system of equations that can be used to find the number of nickels and the number of dimes is:

$0.05n+0.10d=1.85...(1)$

$0.10d+0.10=2*(0.05n)...(2)$

Find the value of x.

puteri [66]

Answer:

x=6,24

Step-by-step explanation:

Use the Theorem of Pythagoras.

H^2= S^2+ S^2

8^2= 5^2 + S^2

64-25 = S^2

39 = S^2

6,24= S

S is x therefore x = 6,24

-1/2x + 6 < 4x - 3<br> i need to find the value of X with step-by-step explanation

WITCHER [35]

Answer:

x > 2

Step-by-step explanation:

-1/2x + 6 < 4x - 3

Start by adding 1/2x to both sides to get both x's on the same side

6 < 4 1/2x - 3

Add 3 to both sides to keep the x's by themselves on one side

9 < 4 1/2x

Divide both sides by 4 1/2 to get x by itself

2 < x so x > 2
