Answer:

Car A went 60 km in 3/4 hour, mean 60: 3/4=80 km per hour.

Car B went 80km in 4/5 hour, mean 80;4/5= 100km per hour.

So Car B went faster than Car A and faster than 20 km.  That will be help.

3x + 7m + 4x - 5m + 25
mart [117]
7x+2m+25 I believe is the answer
So basically I added the x’s first 3x+4x=7x
Next I added the m’s 7m-5m=2m
That left 25
And a + are left
So the two answers 7x+2m and add +25
7x+2m+25

Answer:

d=2√13

Step-by-step explanation:

B(1,4) T(4,6)  what is BD

find BT

d=√(x2-x1)²+(y2-y1)²

d=√(4-1)²+(6-4)²

d=√3²+2²

d=√9+4

d=√13 this is haf the distance

BD=2d=2√13

Megan creates a scale drawing of a car. The ratio of her scale drawing length to actual car
Alika [10]

Answer:

Givens

  • The length of the car in her drawing is 6 cm.
  • The scale is 3 cm : 2 m.
  • Ivan draws with a relation 2 cm : 1 m.

First, we need to find the actual length of the car using Megan's ratio.

If 2 centimeters is equivalent to 1 actual meter of the car, 6 centimeters of drawing would be equal to

M=6cm \times \frac{2m}{3cm} =4m

Therefore, the car is 4 meters long.

Now, using this information, we can find the length of the scale drawing of Ivan.

I=4m \times \frac{2cm}{1m}=8cm

Therefore, Ivan's drawing is 8 centimeters long.

(3,-3), slope 3 write an equation of the line that passes through the given point and has the given slope
tester [92]

Answer:

y = 3x - 12

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 3, thus

y = 3x + c ← is the partial equation

To find c substitute (3, - 3) into the partial equation

- 3 = 9 + c ⇒ c = - 3 - 9 = - 12

y = 3x - 12 ← equation of line
