Anis that cosine and sine?
Step-by-step explanation:
A, D, and E are true
One X on the line plot marks one time something happened. So the two x’s above the 1 means that he practiced piano for one hour (see to the right that says hours next to the numbers, so 1=1 hour) two times.
45 minutes is 3/4 of an hour, and is the mark right between 1/2 and 1. There is one x above this mark, so that means Thaddeus practiced for 45 minutes one time, so B is false
Thadeus practiced piano for 30 minutes two times, so C is false because he didn’t mostly practice for thirty minutes.
D is correct because there are 2 Xs above the 0, which means two times he practiced for zero hours, which means he didn’t practice at all.
E is correct because 15 minutes is 1/4 of an hour, so it is the mark between 0 and 1/2. We see there are three x’s there, so that means he practiced for 15 minutes 3 times.
I hope this helps! Let me know if you want me to explain it differently.
Answer:
I think its D
Step-by-step explanation:
lmk if its wrong
1.5 because 2/12=1/6 9 x (1/6) =1.5 gallons of water.
To solve 10x-35+3ax=5ax-7a, we'll need to assume that a is a constant and that we are to solve for the variable x. To accomplish this, group all the x terms together on one side and all of the no-x terms on the other:
10x + 3ax - 5ax = -7a + 35
Factoring x out of the left side, we get:
x(10 - 2a) = 7(5 - a). Dividing both sides by (10 - 2a), we get:
7(5 - a)
x = ------------ = 7/2
2(5 - a)
x has the value 7/2.
