Y=8c+0.75t
Y represents total amount for a pizza with toppings
Answer:$257.5
Step-by-step explanation: add all the amounts then divide by 4
Rewrite the second equation in same form as the first So we have
c + 4d = 8
c - 4d = -6 Now add:-
2c + 0 = 2
2c = 2
c = 1
Now substitute c = 1 in the first equation:-
1 + 4d = 8
4d = 7
d = 7/4 = 1 3/4
Answer c = 1 and d = 1 3/4 Answer
Using complementary angles, <X is equal to <Z, so it's <Z = 35°.
The only values a cosine can have are from -1 to 1.
