<u>Answer</u>
7/729
<u>Explanation</u>
The question requires to you to find the value of x.
9³x = 7
729 x = 7
x = 7/729
Answer:
3. 91.125
4. 30.375
Step-by-step explanation:
just multiply all of the sides
MARK ME BRAINLIEST
Replace each of the x values given to see if they give 0.
0=(2/3)³+(2/3)²-1
0=(8/27)+(4/9)-1
0≠-0.259
0=(1)³+(1)²-1
0≠1
Therefore, you can see that the solution would have to be between 2/3 and 1.

Answer:
3
Step-by-step explanation:
$1.75 (ice cream) + $0.35 (topping) * x (some toppings) = $2.80, so I can rewrite it like that: 1.75+0.35x=2.80
1) Move the constant to the right side and change its sign: 0.35x=2.8-1.75
2) Substract the numbers: 0.35x=1.05
3) Divide the both sides of the equation by 0.35
4) x=3
P=presne amount=5000
A=furutre amount which you want to be 5304.50
solve for r
5304.50=5000(1+r)^2
divide both sides by 5000
1.0609=(1+r)^2
sqrt both sides (remember to get positive and negative roots)
+/-1.03=1+r
minus 1 both sides
+/-1.03-1=r
+1.03-1=r=0.03=3%
-1.03-1=r=-2.03=false, no negative percents
answer is 3%
