Answer:
x ≈ 6.5
Step-by-step explanation:
We have the epresion
and we want to find the value of
.
Let's do it step-by-step
Step 1. Multiply both sides of the equation by 20



Step 2. use the reflexive property of equality: if
then 


Step 3. Using a calculator we get that
. Replacing that value we get

x ≈ 6.5
We can conclude that the value of x is approximately 6.5
Answer:
AGD=180-90
=90
FGD=CGE=23
AGF=90-23
=<em><u>67degrees</u></em>
Answer: the ordered pair is (-14,-6)
Step by step:
x – 2y = -2 (Eq. 1)
x – 4y = 10 (Eq. 2)
Isolate x in Eq. 2:
x = -2 + 2y
Substitute that solution x in Eq. 2:
x - 4y = 10
-2 + 2y - 4y = 10
Solve for y:
-2 - 2y = 10
-2y = 10 + 2 = 12
y = -6
Then calculate value for x using the above value for y
x = -2 + 2y
x = -2 + 2(-6) = -14
The solution is (x,y)=(-14,-6)
That's such a broad question, and super subjective. I'd probably say that you learn math effectively from a good teacher or tutor, or if you're an individual learner, perhaps a textbook or any kind of online resource.
f(5) is 3.
Step-by-step explanation:
- Step 1: Given that f(x) = 3. To find f(5), substitute 5 in place of x.
⇒ f(x) = f(5) = 3
