Answer:
The man has 6 GHc20.00 notes and 4 GHc10.00 left
Step-by-step explanation:
Given
Amount = 3 GH¢50.00, 7 GH¢20.00 and 5 GH¢10.00
Spendings = GH¢80,00
Required
Determine how many GH¢20.00 and GH¢10.00 notes left
The amount he has can be represented as:
This can be represented as:
Represent:
GHc50.00 with x, GHc20.00 with y and GHc10.00 with z
So, we have:
Subtract the spendings from the total to get amount left
Collect Like Terms
Recall that, we have represented:
GHc50.00 with x, GHc20.00 with y and GHc10.00 with z
<em>This means that, the man has 6 GHc20.00 notes and 4 GHc10.00 left</em>
Answer:
m∠1=114
m∠2=66
Step-by-step explanation:
First, let's find the m∠2
∠2 is inside a triangle, and the angles in a triangle must add to 180 degrees.
So,
55+59+∠2=180
Add 55 and 59
114+∠2=180
We are trying to find ∠2, so we have to get it by itself.
114 is being added on to ∠2. To undo this, subtract 114 from both sides.
114-114+∠2=180-114
∠2=66
Now we know the m∠2, but we still have to find m∠1.
∠2 and ∠1 are on a straight line. This means they are supplementary angles and add to 180 degrees.
∠1+∠2=180
We know that ∠2 is 66, so we can substitute it in.
∠1+66=180
66 is being added onto ∠1. To undo this, subtract 66 from both sides.
∠1+66-66=180-66
∠1=114
We have that
y = 2x + 8
for x=1-----------> y=2*1+8=10
for x=2-----------> y=2*2+8=12
for x=3-----------> y=2*3+8=14
.
.
.
the equation y = 2x + 8 ----------- > defines y as a function of x, because <span>for each x there is only one value of y</span>.
the answer is
yes, the equation y = 2x + 8 defines y as a function of x
