Answer:
Presumably you're solving for x here? Without further information we'll assume that.
With that in mind, x is approximately equal to 0.86 and -0.46
Step-by-step explanation:
Let's start by putting it in the usual ax² + bx + c format.
let's solve it. First we'll multiply both sides by five, making the first term a perfect square:
Now we'll add 11 to both sides:
Which makes the left side a perfect square:
And now we can solve for x:
Note that there's no apparent way of drawing the ± symbol when editing equations, so take that + sign as actually being ±.
That gives us two answers:
Answer:b
Step-by-step explanation:
-9-8x=2(7+4x)
First you are going to distribute the 2 to (7+4x) then you will get both Xs on one side
-9-8x=2(7+4x)
-9-8x= 14+8x
+8x. +8x
=-9=14+16x
Now subtract 14 from both sides
9=14+16x
-14 -14
-23=16x
Divide by 16
Your answer will be x= -23/16
Answer:
The correct answer is <u>Jamal hiked </u><u> miles.</u>
Step-by-step explanation:
To solve this math problem, you will need to convert mixed numbered fractions, into improper fractions.
To do that, you will need to multiply the whole number with the denominator (Ex: 5 × 3 = 15), then when you receive the answer, add the answer with the numerator (Ex: 15 + 1 = 16), finally, you should receive a new answer, and to finalize the improper fraction, you always need to keep the denominator the same (Ex: The denominator is 3 so use the new answer as a numerator replacement. )
--
After you have converted all the mixed numbers into improper fractions in the math problem, you are then able to use <u>multiplication</u>.
--
But first we have to calculate how long the second trail was.
miles. Then, convert the mixed number into improper. ()
--
Now add the number of miles of both trails.
With the result as:
Answer : 1.6
Explanation : you add all of the x value and constant values and then divide x by the constant value
