<span>389/x=47
To solve this, you must isolate x on one side.
First multiply both sides by x.
x(389/x) = x(47)
389 = 47x
Now divide both sides by 47 to find x.
389/47 = x
X is 389/47.</span>
Answer:
1 Add 88 to both sides.
2x=10+8
2x=10+8
2 Simplify 10+810+8 to 1818.
2x=18
2x=18
3 Divide both sides by 22.
x=\frac{18}{2}
x=

18
4 Simplify \frac{18}{2}

to 99.
x=9
x=9
Step-by-step explanation:
2x−8=10
1 Let x=9x=9.
2\times 9-8=10
2×9−8=10
2 Simplify 2\times 92×9 to 1818.
18-8=10
18−8=10
3 Simplify 18-818−8 to 1010.
10=10
10=10
4:3 for 21 balloons is essentially
4x + 3x = 21
7x = 21
x = 3
We can multiply 4 and 3:
4*3 = 12
Kali had 12 blue balloons at her party
To find Ken's speed divide total distance by total time:
174 miles / 3 hours = 58 miles per hour.
In the equation for Brenda, the 57 is the miles per hour because you would multiply that by x ( hours) to get total miles (y).
Ken had the faster driving speed.
Answer:
f(a) = a^2 + 2a + 1
Step-by-step explanation:
Given the function f(x)= x^2 +2x + 1, find: f(a):
Merely substitute ' a ' for x:
f(a) = a^2 + 2a + 1
If you really want e*f(a), multiply the above by e:
e*f(a) = ea^2 + 2ea + e
