Answer:
D.Saturday 8:40am
Step-by-step explanation:
11+8=19 (7)
45+55=100
one hour(100) makes 60 minutes
100-60=40
Therefore the answer is Saturday 8:40am
Answer:
A
Step-by-step explanation:
Answer:
y = 4x + 5.5
Step-by-step explanation:
We put 2y in the y spot, obviously
2y = mx + b
Then we put 8x in the x spot
2y = 8x + b
Then we put 11 in the b spot
2y = 8x + 11
Then, to simplify, we divided by equation by two (it still gives the same results)
y = 4x + 5.5
Answer:
3x + 11
Step-by-step explanation:
Remember BPEMDAS.
"Three times a number" is saying multiply 3 times a variable; in this case, <em>x</em>. So we have 3x
"The sun of 3x and 11" is saying add our 3x and 11, so: 3x + 11
