Answer:

30 and 6

Explanation:

Let the numbers be x and y. Then

x+y=36
x−y=24

Adding the two equations together gives

2x=60

∴x=30

Substituting this back into either of the equations gives y=6

Sum means add.
difference means subtract.

x + y = 36
x - y = 24 Just to make it complete, I finish the problem. Add the two equations.
=======
2x = 60 Divide by 2
x = 60/2
x = 30

x + y = 36 Substitute for x
30 + y = 36 Subtract 30
y = 36 - 30
y = 6

So the solution point is (30,6)

Adrian has a points card for a movie theater.

ANEK [815]

Answer: v ≥ 6

This means that Adrian needs to do at least 6 visits.

Step-by-step explanation:

First, we know that he gets 20 points just for signing up, so he starts with 20 points.

Now, if he makes v visits, knowing that he gets 2.5 points per visit, he will have a total of:

20 + 2.5*v

points.

And he needs to get at least 35 points, then the total number of points must be such that:

points ≥ 35

and we know that:

points = 20 + 2.5*v

then we have the inequality:

20 + 2.5*v ≥ 35

Now we can solve this for v, so we need to isolate v in one side of the equation:

2.5*v ≥ 35 - 20 = 15

2.5*v ≥ 15

v ≥ 15/2.5 = 6

v ≥ 6

So he needs to make at least 6 visits.

According to the Venn diagram below, what is P(A∩B∩C)?

weqwewe [10]

The upside down U means intersection

A intersect B intersect C is where all 3 circles overlap.

Sum up all the numbers to get 50

P (a intersect b intersect c) = 6/50 = 3/25

Drag each tile to the correct box. The water level of a tank every minute since it began filling is indicated by segments A, B,

The least to greatest slope, the segments are B, C, and A.

We have given that,

The water level of a tank every minute since it began filling is indicated by segments A, B, and C on the graph below.

A graph represents the water level to fill the tank on Y-axis per time on X-axis.

The rate of increase of water level is indicated by the slope of the segment. The slope is the ratio of rise to run, and is related to the angle the segment makes with the +x axis.

Segments that have more rise for the same run have greater slope. Segments that make a larger reference angle with the +x axis have a larger slope.

Here, segment B has the least slope, followed by C, then A, which has the largest slope.

In order, the least to greatest slope, the segments are B, C, and A.
