Answer:
T=-12
Step-by-step explanation:
Isolate variable by subtracting 4 on both sides
t=-12
The answer is C .2417 because you add them then divide by 7
Answer:
The system would be:
4x + 2y = 140
2x + 3y = 150
Step-by-step explanation:
If we represent the cost of sweats by the letter x and the jeans by the letter y, we can then write an equation for each of the situations using the number of each in each situation.
4x + 2y = 140
2x + 3y = 150
Well, let's do the math. The formula of a cylinder is 2 (pi, which will be estimated to 3.14) r h + 2 pi (radius times radius).
First of all, do 2 x pi, which is 6.28. Multiply 6.28 x 1.4 is 8.792. 8.792 x 5 = 43.96.
Now for 2 times 3.14 again, which is 6.28. But this time, we do 1.4 x 1.4, which is 1.96. With our new number, we do 6.28 x 1.96, which is 12.3088.
Add 43.96 + 12.3088, and you get 56.2988. You can round it to 56.3. So, the answer is 56.3 inches.
Answer:
The value of h'(7) = 44 .
Step-by-step explanation:
Given:
f'(7)=9 and g(7)= 5
We have to find : h'(7)
Also,
⇔ 
...equation (i)
Plugging the value of 'x' = 7 in equation (i) the equation can be re-framed as:
⇔ 
⇔
Now plugging the value of f'=(7)=9 and g(7)=5 in the above equation:
⇔ 
⇔ 
⇔ 
So the value of h=(7) = 44 .
