Answer:
c
Step-by-step explanation:
vshsbjzjskkzizjz shjskzoa
V=vanila
c=chocolate
4v+1c=45
v+c=27
mulitply 2nd equation by -1 and add to top one
-v-c=-27
<u>4v+1c=45 +</u>
<u />3v+0c=18
3v=18
divide by 3
v=6
sub back
v+c=27
6+c=27
c=21
21 choc and 6 van
A.
v+c=27
4v+1c=45
v=number of vanila wafers bought
c=number of chocolate wafers bought
B. 21 chocolate and 7
I got the answer with math because math is fun and tada
G=b-ca
Subtract b from both sides
G-b=-ca
Divide by -c
(G-b)/-c=a
I hope this Helps!
Answer: length of DE is about 3.3 ft
Step-by-step explanation: A calculator is necessary!
DE is the unknown hypotenuse of the triangle
get the sine of 23° = 0.3907311285
Use the equation for sine
<em>sin = o/h</em> .
To find h, Substitute values for sin and o. O is EC, Opposite the 23° angle D
<em>0.3907311285 = 1.3/h</em> multiply both sides by h
h(0.3907311285) = 1.3 divide both sides by 0.3907311285
h = 1.3/0.3907311285
3.327096065 = h, the length of the hypotenuse, DE.
9/18 or 50% if you toss the coin because when you toss 1 coin you get a 1/2 chance of getting tails. Do that nine times and you get 9/18
