Solve for X
−3.5=−4.6x−5.1
Enter your answer as a fraction in simplest form in the box.
The solution of the expression will be;
⇒ x = - 8/23
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ - 3.5 = - 4.6x - 5.1
Now,
Solve the expression as;
The expression is,
⇒ - 3.5 = - 4.6x - 5.1
Solve for x as;
⇒ - 3.5 + 5.1 = - 4.6x
⇒ 1.6 = - 4.6x
⇒ -4.6x = 1.6
⇒ x = 1.6 / - 4.6
⇒ x = - 16/46
⇒ x = - 8/23
Thus, The solution of the expression will be;
⇒ x = - 8/23

Brandon buys a radio for $48.81 in a state where the sales tax is 7%.
can someone pls help?
Answer:
$48.81 x 0.07 = 3.4167
$48.81 + $3.4167 = $52.2267
$52.23
Step-by-step explanation:
The shirt cost $48.81, and the sales tax is 7%. First convert the 7% into a decimal and you get 0.07, and then multiply that to the $48.81. You get left with $3.4167 and then add that to the $48.81 to get $52.2267. But, you have to shorten the numbers to make it look like money by simplifing. So the total is $52.23.
Answer:52.17
Step-by-step explanation: You go to your calculator and type 7% × 48.81

Evaluate when x = -3 and y= -1:
Evaluate when x = 3, y = -3 and z = -2:
Which numerical expression is obtained by substituting x= 2, y= 6,
and z = 3 into the expression shown? x - (y+z)
Evaluate when x = 3, y = 2, and z = 4:
here is the answer: so if x = 3, y =2 and z = 4 then the answer is 3 - (2+4)

how to stop antixty attack?
i dont know how to spell.
Answer:
to Stop anxiety attract
take a deep breath hold it for some time and then relax your body when exhaling
Don't think Brainly is the place to ask but If your not getting enough sleep, that can be why so make sure to SLEEP and take naps at around 1:00pm and Try to wake up at 3:00pm
Aerobic activity can be calming. Avoid caffeine, alcohol and smoking which act as triggers for the attack. Regular physical activity helps in releasing the anxiety.
Easier ways are to breathe slow and deep breathing is the cornerstone of calm. Start by breathing in and out slowly.
Drink more water. Dehydration may affect anxiety in a variety of ways. And raw fruits and vegetables are the best foods for panic attack because they act as antioxidants in your body.
