4.72 x 1 = 4.72
8 x X =8x
We need to let the X alone so
4.72 divided 8 = 0.59
1 battery = 0.59
Answer:
15$
Step-by-step explanation:
Okey so first we establish that 25 is 100%
Matthew gets 60%
First we find 10% by dividing both sides by 10
2.5 = 10%
Then we times these numbers by 6 to find 60%
<u>60% = 15</u>
Matthew will earn <u>15$</u>
Luke will earn 10$
Answers:
a = -6/37
b = -1/37
============================================================
Explanation:
Let's start things off by computing the derivatives we'll need

Apply substitution to get

I've factored things in such a way that we have something in the form Msin(x) + Ncos(x), where M and N are coefficients based on the constants a,b.
The right hand side is simply sin(x). So we want that cos(x) term to go away. To do so, we need the coefficient (a-6b) in front of that cosine to be zero
a-6b = 0
a = 6b
At the same time, we want the (-6a-b)sin(x) term to have its coefficient be 1. That way we simplify the left hand side to sin(x)
-6a -b = 1
-6(6b) - b = 1 .... plug in a = 6b
-36b - b = 1
-37b = 1
b = -1/37
Use this to find 'a'
a = 6b
a = 6(-1/37)
a = -6/37
Answer:
Step-by-step explanation:
6x-9y=3
+x-9y=-22
first you take x-9y=-22 *-1 which will equal -x+9y=22
then you add
6x-9y=3
+-x+9y=22
----------------
5x=25
÷5 ÷5= x=5 then you plug 5 into each x spot
