Answer 1

Answer:

Hey there!☺

$Answer:\boxed{x=2}$

$Explanation:$

$3(-x+4)=7x-8$

Let's start by simplifying both sides. First, we distribute.

$(3)(-x)+(3)(4)=7x+-8$

$-3x+12=7x+-8$

$-3x+12=7x-8$

Now let's subtract 7x from both sides.

$-3x+12-7x=7x-8-7x\n-10x+12=-8$

Now we will subtract 12 from both sides.

$-10x+12-12=-8-12\n-10x=-20$

In our last/final step, we will divide both sides by -10.

$(-10x)/(-10)=(-20)/(-10)$

Now simplify -20/-10.

$-20/-10=2$

$x=2$

Hope this helps!

1 * 1 = 1
11 * 11 = 121
111 * 111 = 12321
1111 * 1111 = 1234321
11111 * 11111 = 123454321
111111 * 111111 = 12345654321

the pattern is that with each '1' added, there is another consecutive number added. if there are 3 ones, it I'll go up to 3 and then back down to 1 (111*111=12321)
it is the same like that for every one.

What is a pair of complex numbers called?

Answers

Answer:Complex numbers in the coordinate plane. Each complex number x + yi corresponds to a number pair (x, y) in the plane, so we may say that the complex numbers form a two-dimensional collection. The two coordinates of the pair (x, y) are called the real part and the imaginary part of the complex number.

Step-by-step explanation:

Mr. Wilk is a high school math teacher whose salaryis $33,660 for this school year, which has 180 days.In Mr. Wilk’s school district, substitute teachers are paid $85 per day. If Mr. Walker takes a day off without payand a substitute teacher is paid to teach his classes. How much less does the school district pay in salary by payinga substitute teacher instead of Mr. Wilk for this particukar day?

Answers

Mr. Wilk's salary for 180 days = $33,660
Mr. Wilk's salary for 1 day = $?
By unitary method:
Days Salary
180 $33,660
1 ?
By cross-multiplication:
1*33660/180
33660/180 = $187
Mr. Wilk's salary per day = $187
Substitute teacher's salary per day = $85
Difference in salary = 187-85
= $102
The school district pays $102 less to the substitute teacher.
