Answer:
3^3 in = 27 in
Step-by-step explanation:
The area is given by the formula ...
A = LW
Filling in the given values, we can find the unknown.
3^7 in^2 = (3^4 in)×W
(3^7 in^2)/(3^4 in) = W = 3^3 in . . . . . . . divide by the coefficient of W
The width of the tabletop is 3^3 = 27 inches.
___
The applicable rule of exponents is ...

Solve for v 3(v-2)=7v+6-2(-4v-3)
Answer:
v= -1.5
Step-by-step explanation:
3(v-2)= 7v+6-2(-4v-3)
3v-6= 7v+6+8v+6
3v= 15v+18
-12v= 18
v= -1.5
Alonso brings \$21$21dollar sign, 21 to the market to buy eggs and avocados. He gets eggs that cost \$2.50$2.50dollar sign, 2, point, 50. Then, he notices that the store only sells avocados in bags of 333 for \$5$5dollar sign, 5. He wants to buy as many avocados as he can with his remaining money. Let BBB represent the number of bags of avocados that Alonso buys. 1) Which inequality describes this scenario?
This scenario is described by the following inequality:
[tex]2.5 + 5B \leq 21[/tex]
-------------------------
First, we find Alonso's total spendings.He spends $2.50 in eggs.After that, he buys B bags of avocados, each costing $5, and thus, his spending on avocados is: [tex]5B[/tex]His total spending is given by:[tex]T = 2.5 + 5B[/tex]
-------------------------
He brought $21 to the market, thus, his total spending can be at most $21, that is:[tex]T \leq 21[/tex]
Replacing the equation for T, the inequality is:
[tex]2.5 + 5B \leq 21[/tex]

Answer:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis

It's a bit hard to explain, in my opinion. but I'll give it a go. Lets say you have 10 full pizzas, and you want to split it upon 5 people. Now 5 2 slices is 10, like 5x2 so basically, it's kind of like backwards multiplying. if that makes sense. Think of it like this. if you see something like 14 ÷ 2, think of what number times 2 would be 14. 7, exactly. So Just write the number thats missing. Thats how i like to think of it. What number is missing.

Answer:
x = 17
Step-by-step explanation:
5x + 29 + 2x + 32 = 180 (linear pair means that these angles add up to 180 cos they are in a line)
