Answer:
$18.28
Step-by-step explanation:
Step one:
given data
Kate had a sum of money,she spent 1/8 of the money on a skirt and the remaining amount on a handbag
let the total money be x
so mathematically
x-1/8*x= 16
solve for x
x-x/8= 16
8x-x/8= 16
7x/8=16
cross multiply
7x= 8*16
7x=128
divide both sides by 7
x=128/7
x=$18.28
Answer:
v=kw. 8=k1/2
Step-by-step explanation:
Okay, so here's the equation. v=kw. Varies directly means if v rises, then w rises. If v decreases, then w will decrease. Let me know if that helps! (In case you need it, k=16.)
Answer:
B) 1
Step-by-step explanation:
Given:
We need to solve the given expression.
Now We know that when base of the exponents then the law of indices applied for the same.
Now According to Law of Indices.
On Solving the above expression we get;
Hence The Simplified form of given expression is 1.
The answer for 2ab(xa^9+ya^3-6) is 2a^10bx + 2a^4by-6ab.
What is the mathematical expansion?
A mathematical expansion can be described as the finite combination of symbols which can be seen as one having rules which is usually based on the context that is been used.
The solution for the question is 2a^10bx + 2a^4by-6ab
Therefore, the expansion of 2ab(xa^9+ya^3-6) is 2a^10bx + 2a^4by-6ab.
