According to the Question,

The number of cats and dogs will be 200 and 300, respectively.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

A certain pet store sells only dogs and cats.  In March, the store sold twice as many dogs as cats. In April, the store sold twice the number of dogs that it sold in March and three times the number of cats that it sold in March.

Let the number of cats sold in march be x and the number of dogs sold in march be y. Then the equations will be

y = 2x

Then the number of cats sold in April will be 3x and the number of dogs sold in April will be 2y.

If the total number of pets the store sold in March and April combined was 500. Then we have

x + y + 3x + 2y = 500

x + 2x + 3x + 4x = 500

10x = 500

x = 50

Then the value of y will be

y = 2 (50)

y = 100

Then the number of cats sold will be

⇒ 50 + 3 × 50

⇒ 50 + 150

⇒ 200 cats

Then the number of dogs will be

⇒ 100 + 2 × 100

⇒ 100 + 200

⇒ 300

Thus, the number of cats and dogs will be 200 and 300, respectively.

Step-by-step explanation:

x=y=75°

y+30=z

105=z

!!!!!!!!!!

Answer:

x = 75 degree , y = 75 degree , z = 105 degree

Step-by-step explanation:

x = 75 degree (being corresponding angles)

x=y (being corresponding angles)

75 = y

substituting the value

y + 30

75 + 30

105 degree

z = y + 30 (being corresponding angles)

z = 105 degree

The value of "m" if m% of it is 49 will be 70.

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

A percentage is a minimum number or ratio that is measured by a fraction of 100.

WE need to find the value of "m" if m% of it is 49.

We have been an expression as;

m x m% = 49.

Solving further;

m x m/100 = 49.

m² / 100 = 49

Now, Cross multiplication;

m² / 100 = 49

m² = 4900

On taking square root;

m = √4900

m = 70

Therefore, the value of "m" if m% of it is 49 will be 70.

Answer: B) y=2x+1

Step-by-step explanation:

These are in slope intercept form which is y=mx+b

where m is the slope and b is the value of the y intercept

Since the y-intercept is 1 on this line that leaves us with A, B, and C

Using the communitive property on the equation in C we can make the equation go from y=1-2x to y=-2x+1

This is the same answer as A and since there can't be two of the same answer leaves B as the only possible answer.

Answer:

80

Step-by-step explanation:

This is a pentagon (5 sides), n=5

The sum of internal angles equals (n-2)*180 = 540°

We have

A = 90

B = 180-40

C = 180-x

D = 180-60

E = 180-90

Sum all the angles to equal 540°

90 + 180-40 + 180-x + 180-60 + 180-90 = 540

620-x = 540

solve for x

x = 620 - 540 = 80
