Mice21 [21]3 years ago
5 0

Answer:

y=78

Step-by-step explanation:

\frac{y}{13}-2=4

\frac{y}{13}-2+2=4+2 (Add 2 to both sides to isolate y)

\frac{y}{13}=6 (Simplify)

\frac{y}{13}*13=6*13 (Multiply both sides of the equation by 13 to get rid of the denominator)

y=78 (Simplify)

Hope this helps!

The area of the city of Vancouver is 115 km^2. if the shape of Vancouver is approximately a square, how wide is the city of Vanc
Dmitry [639]

Answer:

The wide of the city is 10.7km

Step-by-step explanation:

To solve this we first have to know the formula to calculate the area of ​​a square

a = area = 115 km²

s = side

a = s * s

now we replace with the known values

115 km² = s * s

115 km² = s²

√(115 km²) = s

10.724km = s

Round to the nearest tenth

s = 10.724km = 10.7km

The wide of the city is 10.7km

5 less than a number is equivalent to 1 more than three times the number. the number is​
lutik1710 [3]

Answer:

x = -1

Step-by-step explanation:

5 less than a number is equivalent to 1 more than three times the number

number = x

x - 5 = 3x + 1

now im going to get the numbers and variable on different sides

x - 5 + 5 = x

3x + 1 - 3x = 1

x + 3x = 4x

1 - 5 = -4

4x = -4

lastly im going to divide each side by 4

4x / 4 = x

-4 / 4 = -1

x = -1

A cat chases a mouse. The cat is originally 4 feet behind the mouse, which is running in the same direction along the same route
Darya [45]

The cat will take 0.8 seconds  to catch up with the mouse

Step-by-step explanation:

Given:

The  distance between the cat and the mouse =  4 feet

cat's speed  = 17 feet per second.

mouse's speed =  12 feet per second

To Find:

how long will it take the cat to catch up with the mouse = ?

Solution:

We know that

distance  = speed x  time

Rewriting the equation for time we get

time  =\frac{distance }{speed}

now we know that distance is  4 feet

and the speed is 17 -12 = 5 feet per second

Thus the time is

= \frac{4}{5}

= 0.8 seconds
