Answer:

The percentage is 26.6%

Step-by-step explanation:

Here, we want to

work

out the percentage change

To do this, we use the percentage change formula

This is,

percentage change = new value-old value)/old value * 100%

= (100-78.98)/78.98 * 100%

21.02/78.98 * 100% = 26.6%

Helen bought notebooks and pencils for school. The number of pencils she bought is given by 6(n-3) , where n is the number of no
pychu [463]
So the number of pencils bought can be represented by an equation: P=6(n-3), where n is the number of notebooks bought. Since Helen bought 5 notebooks, simply plug 5 into n: P=6(5-3)=6(2)=12. So Helen bought 12 pencils.

If y=6 when x=2 over 3 find x when y=12
AlexFokin [52]

Answer:

4/3 or 1 1/3

Step-by-step explanation:

So if y = 6, when x = 2/3. Then, x would equal 1 and 1/3, because 12 is twice the amount of 6, so you'd also multiply 2/3 by 2.

(To multiply a whole number by a fraction, first multiply the whole number by the numerator and then divide that by the denominator. For example: 2 × 2 = 4, since you can't really divide 4 by 3 it would stay as is, but you can turn it to a mixed number. 4/3 is the same as 1 whole and an extra 1/3, or in other words 1 1/3).

Hope this helped :)

Solve the system of equations using the elimination method. 1.Solve {x + 3y = -15
shutvik [7]

An equation is formed of two equal expressions. The solution is (-9,-2).

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

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the equation x + 3y = -15 and -3x + 2y = 23,

Step 1- Multiply the equations to make the coefficients match in either the x- or y-variable.

x + 3y = -15

3x + 9y = -45

Step2- After you multiply, add or subtract the two equations.

3x + 9y -3x + 2y = -45 + 23

Step 3- Then solve for the variables that is left.

11y = -22

y = -2

Step4- Substitute the value of y in any one of equations to solve for x.

x + 3(-2) = -15

x - 6 = -15

x = -9

Hence, The solution is (-9,-2).
