Answer:
6.
Step-by-step explanation:
We can start by defining a couple things.
x = amount of nickels
y = amount of dimes
Since he has the same amount of each, we can say this.
x = y
And because we know it totals 0.90, we can say this.
0.05x + 0.10y = 0.90
then, we substitute and get this.
0.05x + 0.10x = 0.90
Simplify.
0.15x = 0.90
Divide both sides by 0.15.
x = 6
So we have 6 nickels, and they both are the same, so we have 6 dimes.
I'm pretty sure the answer is -3
4:3 (simplified) and 16:12 (doubled) both work
Hope this helps!
<u>Answer:</u>
ΔLNM is proved as isosceles triangle. Below for explanation.
<u>Step-by-step explanation:</u>
We know that:
- AMBX = Square
- Squares have equal sides
Since AMBX is a square, AL must equal to BN because they are the extra lengths of the square. The lengths of the square are AM, MB, BX, XA.
- Side of square + Extra length = Side of triangle
This can tell us that the two sides of the triangle are equal. We also know that if 2 sides of a triangle are equal, it is classified as an isosceles triangle. Hence, ΔLNM is proved as an isosceles triangle.
