Use the model to solve for x.
2 answers:
Answer:
B; x = 8
Step-by-step explanation:
I think I understand what the picture is saying. So,
On the left hand side, the x's and +1's represent the following expression:
.
On the right hand side, the x's and -1's represent the following expression:
.
Put these two together and you get the following equation:
=
First, Solve for x:
8 = x
So, when solving the equation, x is equal to 8

table that shows the hair lengths y (in inches) of your friend and her cousin in different months x.
Month Friends Hair(in) Cousins Hair(in)
3 4 7
8 6.5 9.
To solve for the cousins hair, recall that the equation of a line is given by
y = mx + c
From the table,
7 = 3m + c . . . (1)
9 = 8m + c . . . (2)
(1) - (2) ⇒ -2 = -5m
Substituting for m into equation (1) gives:
Therefore, the equation representing the growth of the cousin's hair is given by y = 1.2x + 5.8

Since, the number w and 0.8 are additive inverses.
A number 'a' is said to have an additive inverse '-a' if "a+ (-a)= 0".
Since, 'w' and '0.8' are additive inverses of each other such that
Therefore, the value of 'w' should be '-0.8' so that .
So, the value of 'w' is =0.8
Now, Refer to the attached image which represents the position of 0.8 , w ( that is -0.8) and the sum of 0.8 and w.
Sum of 0.8 and w = 0.8 + w
= 0.8 +(-0.8)
= 0.
Answer:
Susan's take-home pay <u>$48,645</u>.
Step-by-step explanation:
Given:
Susan, a recent college graduate, makes a base salary of $70,000 per year. Susan has federal income tax withholding of $12,000, and state tax withholding of $4,000. Employers are required to withhold a 6.2% Social Security tax and a 1.45% Medicare tax.
Now, to find Susan's take-home pay.
Basic salary = $70,000.
Now, her tax withholdings:
Federal income tax = $12,000.
State tax = $4,000.
<u><em>Social security tax = 6.2% of $70,000.</em></u>
<u><em>Medicare tax = 1.45% of $70,000.</em></u>
Now, to get the take-home pay of Susan's we subtract all the tax holdings of federal, state, social and medicare from the basic salary:
Therefore, Susan's take-home pay $48,645.
