Answer:

25 or +25

Step-by-step explanation:

we're going to represent sea level as 0, anything below sea level is negative, and anything above is positive. because your question is 25 feet above sea level, it will simply be 25 or +25. if it were 25 feet below it would be -25

Solve the system of equations −4x+3y=−2 y=x−1 x = y =

dolphi86 [110]

Answer: x = -1 and y = -2

Step-by-step explanation:

So if you know y = x-1 you can plug that in where y is in the first equation

-4x + 3(x-1) = -2

Distribute the 3:

-4x +3x -3 = -2

Combine like terms:
-x -3 = -2

Add 3 to both sides:
-x = 1

Multiply by -1:
X = -1

Then you plug that into the other equation to get y=(-1)-1

Which is -2

Let A be an m x n matrix and let b be a vector in RM. Three of the following four statements are all equivalent to each other. C

rusak2 [61]

Answer:

Step-by-step explanation:

From the given information:

If A = m × n matrix

where;

b is a vector in $R^m$

Then; the statement that doesn't fit and is not related to the other three from the given options is Option A.

This is because the statement in Option A appears to be inconsistent. For the model Ax=b to have a solution, A must be non-singular and b must be in A's column space.

Option c and d are equivalent, also option b and c are equivalent.

In rectangle ABCD with side AD = 6 cm, point M is the midpoint of side

SpyIntel [72]

The triangle that is formed by AMB is a 45 45 90 triangle, so meaning the legs are equal. so in can be concluded that AD = MD, since M is the midpoint of CD, then CD = 2AD
CD = 2(6) = 12 cm

so the perimeter is of the rectangle ABCD is
P = 2l + 2w
P = 2(6) + 2(12)
P = 12 + 24
P = 26 cm

The coffee cups can hold 7/9 of a pint of liquid. If Emily puts 2/3 of s pint of coffee into a cup, how much milk can a customer

Bezzdna [24]

1/9 pints of milk can be added by a customer

Step-by-step explanation:

We have to subtract simple fractions to find the amount of milk that can be added to a cup of coffee

Given

Total Capacity of a cup = 7/9 pints

Coffee to be added in a cup = 2/3 pints

So in order to find the amount of milk that can be added we have to subtract the amount of coffee from the total capacity of cup.

So,

$Amount\ of\ milk = \frac{7}{9} - \frac{2}{3}\\=\frac{7-6}{9} = \frac{1}{9}$

Hence,

1/9 pints of milk can be added by a customer

Can someone help with this please? Will mark brainliest

Answer:

25 slugs

Step-by-step explanation:

If this is a physics-based problem, which it appears to be, then the formula for finding mass is

w = mg, where w is the weight, m is the mass, and g is acceleration due to gravity. We have our weight and our gravity, so

800 = m(32) so

m = 800/32 and

m = 25 slugs

This answer does not include significant digits. If it needed to, then your answer would be 30 slugs.
