Step-by-step explanation:
To do this equation, we could put it in terms of algebra, lets say the large chocolate bars are represented by L and the small bars by S
April
4S + 6L = $16.50
Bill
4S + 3L = $11.25
Looking at this, we can see that the difference between the two purchases is that Bill bought three less large chocolate bars, this means the difference in total cost equals three large chocolate bars. Using this knowledge.
$16.50 minus $11.25 = $5.25
$5.25 = Three Large Bars
Divide this by three to get the cost of one large bar.
$1.75 is the cost of one single large bar.
Answer: -9 + 21 = t t = 12°C.
Step-by-step explanation: For this problem lets have t be equal to the original temperature in the beginning of the day. The equation -9 + 21 = t represents this situation because it states that if we add the degrees that dropped to the current degrees it will give us our original degrees.
Solve.
-9 + 21 = t (Simply add -9 + 21) -9 + 21 = (+12)
12 = t
So, the original degrees in the beginning of the day was 12°C.
Answer:
X=48
Step-by-step explanation:
x^2+y^2=z^2
but in this case it's z^2-y^2=x^2
so 73^2= 5329
and 55^2=3025
5329-3025=2304
Square Root of 2304 is 48, meaning X=48
Hope this helps!
Hello!
So to find the y-coordinate we need an equation for the line. The equation we can use is
y = mx + b
In this we already know m(the slope which is 3) and we can find b by plugging in the points that are given.
10 = 3(0) + b
10 = 0 + b
10 = b
So now that we've found b, we can use this in our equation
y = 4x + b
So now we can plug in the x-coordinate that we know (2) and find the y - coordinate.
y = 4(2) + 10
y = 8 + 10
y = 18
18 is your y-coordinate
you Need to think of 2 square numbers that add up to make 80
answer:
64 + 16
this means that x = 8 and y = 4
because of the square roots
or
y = 4
and
x = 8
