Answer:
none of above .
Step-by-step explanation:
because the unit of area is always in square forms.
14×12=168
24×7=168
168÷60=2 hours and 48 minutes
2 hours and 48 minutes+ 8:00AM=10:48AM
Answer: 10:48AM
Answer:
1) D: all real/(-inf, +inf) R: all real/(-inf, +inf)
2) x 5 or (-inf, 5)U(5,+inf)
Step-by-step explanation:
1) This is a linear equation, meaning that it has all real numbers all throughout.
This implies that you can plug in any x value and it will have a definite y value.
Domain is all reals or (-inf, +inf)
Range is all reals or (-inf, +inf)
2) We can see that if you plug in the number 5 for x, you would get 5-5 = 0 for the denominator. We can not divide a number by 0, therefore the domain is
x can not equal to 5 or (-inf, 5)U(5,+inf)
Answer:
5 is solution
Step-by-step explanation:
hello,
I am not sure what is expected for this kind of question.
we can notice that 5 is a solution as
hope this helps
A.
If:
j - the price of a glass of juice
p - the price of a pancake special
Then:
3j + 5p = 7.60
j + 2p = 2.90
b.
If:
j + 2p = 2.90
Then:
j = 2.90 - 2p
We can substite j in the first equation.
<span>If:
3j + 5p = 7.60
</span><span>j = 2.90 - 2p
</span>Then:
3×(2.90-2p) + 5p = 7.60
8.70 - 6p + 5p = 7.60
8.70 - p = 7.60
⇒ p = 8.70 - 7.60
⇒ p = 1.10
If:
<span>j = 2.90 - 2p
</span><span>p = 1.10
</span>Then:
j = 2.90 - 2×1.10
j = 2.90 - 2.20
j = 0.70
Thus, the price of a glass of juice is $0.70 and <span>the price of a pancake special is $1.10.
c.
If:
p = 1.10
j = 0.70
Then:
j + p = 1.10 + 0.70 = 1.80
Thus, </span><span>the bill for 1 glass of orange juice and 1 pancake special is $1.80.</span>
