How do you solve for x in the equation 4x-2(x-2)=-9+5x-8

1 answer:

5 0

first distribute the 2 into (x-2) so that the new equation is 4x-2x+4=9+5x-8 Afterwards add up common factors and get the x to one side 2x+4=1+5x (subtract 2x from both sides) 4=1+3x (subtract 1 from both sides) 3=3x (divide by 3 on both sides) 1=x

Hope this helped!!

Sales rise from £400 a week to £504 a week. Calculate the percentage increase

Andrew [12]

Answer:

26%

Step-by-step explanation:

percent change = (new number - old number)/(old number) * 100%

Here, the new number is £504, and the old number is £400.

percent change = (£504 - £400)/(£400) * 100% =

= £104/£400 * 100% = 0.26 * 100% = 26%

Elenna [48]

Answer:

a = 14

Step-by-step explanation:

The mean is the sum of the values divided by the number of values.

$\begin{array}{rcl}\text{Mean}&= &\dfrac{11 + 8 + 7 + a + 16 + 10}{6}\\\\\dfrac{52 + a}{6}& = & 11\\52 + a & = & 66\\a & = & 66 - 52\\& = & \mathbf{14}\\\end{array}$

Please help idk thisssss

ANSWER
$0.073 \% = 0.00073$

EXPLANATION

Recall that,

$\% = \frac{1}{100}$

That is why
$100\%$
is equivalent to
$1.$

This implies that,

$0.073\% = 0.073 \times \frac{1}{100}$

This is the same as,

$0.073\% = \frac{0.073}{100}$

When we are dividing by
$100$
we move the decimal point backwards two times.

This implies that,

$0.073\% = 0.00073$
