Given:
The absolute value equation is
[tex]|x|-2=5[/tex]
To find:
The distance Mary can walk forward, i.e., x.
Solution:
We have,
[tex]|x|-2=5[/tex]
Add 2 on both sides.
[tex]|x|-2+2=5+2[/tex]
[tex]|x|=7[/tex]
[tex]x=\pm 7[/tex]
[tex]x=-7[/tex] and [tex]x=7[/tex]
Here, negative sign represents the distance Mary can walk reverse direction.
Therefore, the correct option is A.

HELP I WILL MARK YOU BRAINLIEST A bag of flour contains 5 pounds of flour. A batch of cookies required 0.10 pounds of flour. How many batches can be made with the 5-pound bag?
Answer:
50 batches
Step-by-step explanation:
A bag of flour = 5 pounds of flour
A batch of cookies = 0.10 pounds of flour
How many batches can be made with the 5-pound bag?
Batch of cookies in 5 pounds of flour = Total pounds of flour / flour needed per batch of cookies
= 5 pounds / 0.10 pounds
= 50 batches of cookies
50 batches of cookies can be made with 5 pounds of flour

0.2(x + 3) - 4(2x - 3) = 3.4
Answer:
x= 1.¯17948¯¯
Explain:
Isolate the variable by dividing each side by factors that don't contain the variable
Answer:
your answer is incorrect
Step-by-step explanation:
0.2 times (x+3) = 0.2x + .6
4(2x-3) = 4 x 2x + 4 x -3 = 4 x 2x + -7 = 6x + -7
0.2x + .6 - 6x + -7 = -5.8x + -7
because you cannot combine terms that are not alike, then your final answer would have to be -5.8x + -7 because you did not give us what x is equal to.

f(x)=22x+14, find f(5)
Answer:
f(5) = 124
Step-by-step explanation:
Step 1: Define
f(x) = 22x + 14
f(5) = x = 5
Step 2: Substitute and evaluate
f(5) = 22(5) + 14
f(5) = 110 + 14
f(5) = 124

what is the soution to following equation: 1/2(x-10)=3/4(x+8)
Answer: x = -44
Step-by-step explanation:
1/2(x - 10) = [tex]\frac{3}{4}[/tex] (x+8) Apply the distributive property
1/2x - 5 = 3/4x + 6 Add 5 to both sides
+5 +5
1/2x = 3/4x + 11 Subtract 3/4x from both sides
-3/4x -3/4x
-1/4x = 11 Divide both sides by -1/4
x = -44
2. Tom makes $50 a day, 5 days a week. If his rent every four weeks was $500, what is
his overall net profit?
Answer:
$500 net profit in 4 weeks
Step-by-step explanation:
+$50 a day, 5 days a week, -$500 every 4 weeks
1. solve for initial profit in 4 weeks
5 profitable day*4 weeks= 20 days Tom makes a profit
20 days*$50= $1000 in 20 days
2. subtract rent from initial profit
1000-500= $500

Solve s3=1 square root
Answer:
If you are solving for s, the answer would be ⅓
Step-by-step explanation:
reason for this is as following.
1. you want to find the square root 1, which is one. because you get 1 by multiplying 1 and 1
2. Next, you want to decide each side by 3 making it s = ⅓
solve for c: c - 12 = 3
Steps to solve:
c - 12 = 3
~Add 12 to both sides
c = 15
Best of Luck!
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{c = 15}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{c - 12 = 3}[/tex]
Move 12 to right hand side and change it's sign
[tex] \dashrightarrow{ \sf{c = 3 + 12}}[/tex]
Add the numbers: 3 and 12
[tex] \dashrightarrow{ \sf{c = 15}}[/tex]
Hope I helped!

What is the solution of 6x= 15
Answer:
2.5
Step-by-step explanation:
When a variable is next to a number (coefficient) it means you need to multiply. In this equation 6x are next to eachother.
Because we don't know what x is, we have to work backwards.
The opposite of multiplying is dividing, so here we can do...
15/6 and that equals 2.5
To check you replace x with 2.5 like so,
6(2.5)= 15 and it is true!
Hope this helps and have a great day!

What is the modulus function?The modulus function is the function which gives the magnitude or absolute of the number in the variable.
|x|=x if x>0
-x if x<0
0 if x=0
So according to question,
|7x+21|=14x
case-1: if 7x+21>0
⇒7x>-21
⇒x>-21/7
⇒x>-3
if 7x+21>0 , Using the modulus function property
|7x+21|=14x
⇒7x+21=14x
⇒14x-7x=21
⇒7x=21
⇒x=21/7
⇒x=3 which is also x>-3
x=3 is the solution
case-2: if 7x+21<0
⇒7x<-21
⇒x<-21/7
⇒x<-3
if 7x+21<0 , Using the modulus function property
|7x+21|=14x
⇒-(7x+21)=14x
⇒-7x-21=14x
⇒14x+7x=-21
⇒21x=-21
⇒x=-21/21
⇒x=-1 for which x<-3 is not true
x=-1 is an extraneous solution.
Therefore the solution is 3 and the extraneous solution is -1.
