Ik the first equation you just distribute three to north numbers and it’ll give you 9x+15 and in the second one you can distribute a negative 1 and it’ll give you 9x+15
Well first to find out how much the cookies are on sale you do
![2.80/7= 0.40 ](https://tex.z-dn.net/?f=2.80%2F7%3D%200.40%0A)
So on sale each cookie is 40 cents each, now to figure out the normal price add 75 cent to the sale price so:
![0.40 + 0.75 = 1.15](https://tex.z-dn.net/?f=0.40%20%2B%200.75%20%3D%201.15)
So that gives us $1.15
So the normal price for the cookies is $1.15 and the sale price is $0.40 cents
20*117.98 + 20*124.32 = $4846.00
<span>$4846.00*1.02 = $4942.92 </span>
<span>40*128.48 = $5139.20 </span>
<span>0.02*5139.20 = $102.78 </span>
<span>$5139.20 - $102.78 = $5036.42 </span>
<span>$5036.42 - $4942.92 = $93.50,
So the answer is (B)</span>
Answer:
B
Step-by-step explanation:
Make a commone demonatore my multiplying.
<span>measure of ∠EGF = 1/2( 180 - 50)
= 1/2(130)
= 65
</span><span>the measure of ∠CGF = 180 - 65
= 115</span>
