Answer: $3^{\circ}C$

Step-by-step explanation:

Given

The temperature on Monday was $-5^{\circ}C$

By Tuesday, it becomes $-2^{\circ}C$

Change in temperature is the difference between the two temperatures.

$\Rightarrow \Delta T=-2-(-5)\\\Rightarrow \Delta T=-2+5\\\Rightarrow \Delta T=3^{\circ}C$

Therefore, the change in temperature is $3^{\circ}C$ .

The normal yearly growth of a plant is 60 inches. The normal growth was ten inches more than twice the amount of last year. What

Usimov [2.4K]

The growth of the plant last year was 25 inches if the normal growth was ten inches more than twice the amount of last year.

<h3>What is linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The normal yearly growth of a plant is 60 inches.

Let's suppose the growth of the plant last year was x

The normal growth was ten inches more than twice the amount of last year.

From the above statement:

10 + 2x = 60

2x = 50

x = 25 inches

Thus, the growth of the plant last year was 25 inches if the normal growth was ten inches more than twice the amount of last year.

If 2L of solution needs to be administered through an IV over 24hours, then how many mililitres of solution needs to be provided

kow [346]

Answer:

83.33 milliliters

Step by step explanation:

2L = 2000 ml Change the liters to milliliters first

2000 ml : 24 hours

x ml : 1 hour

Next you cross multiply : 2000 × 1 hour = 2000 and 24 × x = 24x

Then you divide:

$\frac{24x}{24} : \frac{2000}{24}$

x : 83.3333333...

When this is rounded off it is equal to 83.33

Algebra 2 system of equations

Ahat [919]

6x - y = 31 so y = 6x - 31
substitute y = 6x - 31 into 3x + 7y = 8

3x + 7y = 8
3x + 7(6x - 31) = 8
3x + 42x -217 = 8
45x = 225
x = 5

y = 6x - 31
y = 6(5) - 31
y = 30 - 31
y = -1

answer
x = 5 and y = -1

Solve the system of equations.<br> 14x+5y=31<br> 2x−3y=−29

Nastasia [14]

Answer:

(x, y) = (-1, 9)

Step-by-step explanation:

A graphical solution can be quick and easy. It shows the solution to be ...

(x, y) = (-1, 9)

Another suitable method is Cramer's rule. It makes use of a particular pattern of sum of products of coefficients and constants. The denominator in each case is the same sum of products.

x = (5(-29)-(-3)(31))/(5(2)-(-3)(14)) = -52/52 = -1

y = (31(2)-(-29)(14))/52 = 468/52 = 9
