Layla has $2 worth of dimes and quarters. She has 6 more dimes than quarters. By
following the steps below, determine the number of dimes, I, and the number of
quarters, y, that Layla has.
Answer:
Layla has 4 quarters and 10 dimes
Step-by-step explanation:
A quarter each is 25 cents. And a dime each is 10 cents. counts from 10 10 times and then add 25 4 times and you get 200 which is 2 dollars. Example: 10 20 30 40 50 60 70 80 90 100 with 10 dimes alone that's a dollar 4 quarters equal another dollar so both of those equal 2 dollars. Layla had 4 dimes and 4 quarters when she added 6 more dimes it all equaled 2 dollars. Hopefully this makes sense.
proving answer:
10 - 4 = 6
Theres 6 more dimes than quarters

The LCM of 4 and 6 is . (5 points)
Answer:
10
Step-by-step explanation:
5x + 2y = -3
3x + 3y = 9
Answer:
Step-by-step explanation:
5x + 2y = -3
3x + 3y = 9
15x + 6y = -9
-15x - 15y = -45
-9y = -54
y = 6
5x + 2(6) = -3
5x + 12 = -3
5x = -15
x = -3

Explain how you would find 36x 5/6
mentally.
Answer:
In step-by-step explanation.
Step-by-step explanation:
Multiplying a fraction (like 1/2) is really just dividing by the denominator.
In this case, we can (mentally) divide 36 by 6.
36/6 = 6
So each 1/6 of 36 is 6.
Then we just add 1/6 of 36 five times to get 5/6
6+ 6+ 6+ 6+ 6 (or 6 x 5) and we get 30.
Five friends, including Marlon, purchased two boxes of pizzas. They equally shared the pizza among themselves. How much pizza did Marlon get?

what’s the area of the figure for brainlist ?!
Answer:
4x^4
Step-by-step explanation:
The polygon has 4 right angles, and two consecutive sides are congruent, so it's a square.
For a square:
area = (side)^2
area = (2x^2)^2 = 2x^2 * 2x^2 =
area = 4x^4

Write an
explicit formula for An, the nth term of the sequence 7, -42, 252, ....
Answer:
[tex]A_n = 7(-6)^{n-1}[/tex]
Step-by-step explanation:
Key skills needed: Explicit formula, Geometric sequence
1) This is a geometric sequence, meaning a constant (like 6 or 3.5) is being multiplied to every term. First we need to find the constant.
This can be done by doing -42 ÷ 7 or 252 ÷ -42
-42 ÷ 7 equals -6.
252 ÷ -42 also equals -6.
2) This means that constant is -6.
3) The general form for an explicit formula of a geometric sequence is:
[tex]a_n = a_1(r)^{n-1}[/tex]
--> r means the constant (or common ratio) that is being multiplied.
--> [tex]a_1[/tex] means the first term
--> [tex]a_n[/tex] means the "nth" numbered term (so [tex]a_3[/tex] is the 3rd term, [tex]a_{10}[/tex] is the 10th term and so on).
--> [tex]n-1[/tex] is just the "n" in [tex]a_n[/tex] minus 1.
4) We can use this formula to create an explicit formula for the geometric sequence in the problem.
--> [tex]r = -6[/tex] (Since we got -6 as the constant/common ratio).
--> [tex]a_1 = 7[/tex] (Since 7 is the 1st term)
This means that our formula would be --> [tex]A_n = 7(-6)^{n-1}[/tex]

When the function f(x) = 3(5)x is changed to f(x) = 3(5)x + 22, what is the effect?
Answer:
The original function is an exponential growth function, and so is a new function, but it will be translated in to 2 units.
Step-by-step explanation:
The first function will have a horizontal asymptote at y = 0 and the second function will have a horizontal asymptote at y = 22.
