Answer:
I think so, but don't lose sight
To solve a problem like this, you can use a method called cross-multiplying. This is when you multiply the denominator of the first fraction by the numerator of the other and then multiply the two remaining numbers.
To make this easier on yourself, simplify first!
Multiply x by 2 and multiply 4 by 1.
2x = 4 Divide both sides by 2.
x = 2
You can check this by comparing the fractions with 2 in the place of x.
Simplify!
The fractions are equal, so
x = 2 .
Answer: the 3rd one
Step-by-step explanation:
Answer:
Step-by-step explanation:
let after t hrs they are 24 miles apart.
48t+36t=24
84t=24
t=24/84=2/7 hrs
=2/7×60=120/7 minutes =17+1/7
=17minutes +1/7×60sec
=17 minutes +60/7 sec
=17 min 8 4/7 sec
10.00+00.17 =10.27
Time≈10.27 a.m.
Answer: x = 8
Step-by-step explanation:
Using The Pythagorean theorem (a^2 + b^2 = c^2) we can find A or In This Case X
Plug In The Numbers:
x^2 + 6^2 = 10^2
simplify
x^2 + 36 = 100
Next, Since Were Trying To Find X And Not C, We Subtract B From C Or 36 From 100
x^2 + 36 - 36 = 100 - 36
simplify
x^2 = 64
Next, To Get Rid Of The Square, Were Going To Find The Square Root Of Both Sides Of The Equation
sqr/a = sqr/64
simplify
x = 8
