Answer:
Step-by-step explanation:
Let x m/h be the speed of first bus.
Then speed of second bus=x-13 m/h
fist covers covers distance=3x
second covers the distance=3(x-13)=3x-39
again 3x+(3x-39)=339
6x=339+39=378
x=378/6=63
so speed of first bus=63 m/h
speed of second bus=63-13=50 m/h
You'll need to create two equations and have a 'system of equations' then use direct substitution to turn the equation into one. Whichever equation is easiest to solve for x or y. Solve that one for x or y and plug the result in for the variable in the other equation. Then you will have an equation with only 1 unknown.
the shape of christina’s garden is a rectangle
and trapezoid. The rectangle has a dimensions of 4 units by 2 units. The trapezoid
upper base is 8 units and the lower base is 4 units and the height is 2 units
Area of the garden = area rectangle + area
trapezoid
A = (LW) + 0.5( base1 + base2)(h)
A = ( 4 x 2) + 0.5 ( 8 + 4) (2)
A = 20 sq units
Number of carrots = 20 sq units x 15 carrots/
sq units
<span>= 300 carrots</span>
All you have to do is plug in the tables to T. Since there's 5 tables, your new equation will be C=4x5+2. Then, you solve using pemdas.
C=4x5+2.
C=20+2
C=22
You need 22 chairs.
