Answer:
a = 8.
Step-by-step explanation:
a/4 + 8 = 10 where x is the number to find.
a/ 4 = 10-8 = 2
a = 4*2
a = 8.
Answer:
50.1 deg F
Step-by-step explanation:
1.6deg F for every 1,000ft. You need to get to 9,000ft. 1.6degx9=14.4
64.5deg-14.4deg=50.1degF
Solve for d
ANSWER:
d=5/2y-1
We have that
(3y-8)/12=(y/5)---------> 5*(3y-8)=12*(y)
15y-40=12y-------------> 15y-12y=40
3y=40--------------> y=40/3
y=(40/3)----------> 13.33
the answer is y=40/3 (13.33)
The first step for solving this expression is to divide both sides of the equation by 5².
-(6 - 2)z = -10 ×
![( \frac{10}{5})](https://tex.z-dn.net/?f=%28%20%5Cfrac%7B10%7D%7B5%7D%29%20)
²
Subtract the numbers in the first parenthesis.
-4z = -10 ×
![( \frac{10}{5})](https://tex.z-dn.net/?f=%28%20%5Cfrac%7B10%7D%7B5%7D%29%20)
²
Now,, to raise a fraction to a power,, you must raise the numerator and denominator to that power. This will look like the following:
-4z = -10 ×
![\frac{ 10^{2} }{ 5^{2} }](https://tex.z-dn.net/?f=%20%5Cfrac%7B%2010%5E%7B2%7D%20%7D%7B%205%5E%7B2%7D%20%7D%20)
Reduce the fraction with 5².
-4z = -10 × 2²
Evaluate the power.
-4z = -10 × 4
Multiply the numbers on the right side of the equation.
-4z = -40
Lastly,, divide both sides of the equation by -4 to get your final answer.
z = 10
