Answers
First, we need to establish what we know, and what we do not know.
We know that Rosie knows how many yoga classes she has.
We know that she knows how many yoga classes she bought.
She does not know how much each yoga class costs.
So, that cancels out A, B, and C because she doesn't know how much one yoga class costs.
It can only be D, because D tells us that she knows the total is $30, but not the amount each class costs.
Answer:
D.
Rosie knows that she paid a total of $30 for the yoga classes. She does not know how many classes she bought.
LISTEN all i know is that this the RIGHT one

Solve for u by simplifying both sides of the equation, then isolating the variable.
u = 8
10u + 7 = 16u - 32 -9
10u + 7 = 16u - 41
41 + 7 = 16u - 10u
6u = 48
u = 48/6
u = 8

Step-by-step explanation:
Shreyas ate of the entire pizza on the first day.
Entire pizza contained calories = 2,500
Therefore, Shreyas consumed calories on the first day = of 2500
= × 2500
= 0.625 × 2500
= 1,562.5 calories
Shreyas consumed 1,562.5 calories on the first day.

First, cancel 2 on both sides. / Your problem should look like:
Second, expand. / Your problem should look like:
Third, simplify -3d + 15 - 2 to get -3d + 13. / Your problem should look like:
Fourth, add 3d to both sides. / Your problem should look like:
Fifth, add d + 3d to get 4d. / Your problem should look like:
Sixth, divide both sides by 4. / Your problem should look like:
Answer as fraction:
Answer as decimal:
2+d=2−3(d−5)−2
2+d=2+(−3)(d)+(−3)(−5)+−2(Distribute)
2+d=2+−3d+15+−2
d+2=(−3d)+(2+15+−2)(Combine Like Terms)
d+2=−3d+15
Add 3d to both sides.
d+2+3d=−3d+15+3d
4d+2=15
Subtract 2 from both sides.
4d+2−2=15−2
4d=13
Divide both sides by 4.
4d/4=13/4
d=13/4

Answer:
Hence, the value of expression (2) is ⇒ 1.08.
Step-by-step explanation:
We are given a fact such that:
4.86 : 0.45=10.8 ------(1)
Now we are asked to find the value of the mathematical expression:
4.86 : 4.5 --------(2) without actually dividing.
We could clearly see that the numerator in both the mathematical expression is same only there is a difference in there denominator.
The denominator in second expression is just a multiplication of the denominator of first expression by 10.
Hence we divide both side of expression (1) by 10 to obtain the expression (2).
i.e. 4.86: (0.45×10)=10.8:10
i.e. 4.86: 4.5= 1.08
Hence, the value of expression (2) is 1.08.
