Answer:
Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.
Point Form:
(−11,−5/4)
Equation Form:
x=−11,y=−5/4
Answer:
51 degress
Step-by-step explanation:
sin x = 7/9
x = sin^-1 (7/9)
simply using a calculator.
A.
s=number of strawberry wafers
c=number of chocolate wafers
3s+1c=30
s+c=22
B.
multiply 2nd equation by -1 to do elimination
add to the first equation
3s+1c=30
<u>-s-c=-22 +</u>
2s+0c=8
2s=8
divide by 2
s=4
sub back
s+c=22
4+c=22
c=18
I used elimiation because it seemed right for this one
I can also do subsitution
3s+1c=30
s+c=22
minus s both sides in 2nd equation
c=22-s
sub for c in other equation
3s+22-s=30
2s+22=30
minus 22 both sides
2s=8
divide by 2
s=4
and now
c=22-s
c=22-4
c=18
substiotion because it's easier for some people to see
18 chocolate
4 strawberry
