Step-by-step explanation:
The coefficients of the y terms are -3 and 2. The least common multiple of 3 and 2 is 6. So multiply the first equation by 2 and the second equation by 3, so that the y terms have a coefficient of 6.
4x − 6y = 42
-18x + 6y = 21
The signs are opposite, so add the equations together.
-14x = 63
x = -9/2
Answer:
U' = (0,2)
V' = (0,5)
W' = (-5,5)
Step-by-step explanation:
To get these, you can subtract 2 from the x-value because they are moving 2 units to the left and add 2 to the y-value because they are moving 2 units up.
Answer:
Option B. is the right choice.
Step-by-step explanation:
Divide the given figure such that the divided parts represent either a rectangle or square.
Take one small box in each divided figure as one unit length.
Answer:
C: Roman has a 5-liter jug of water. How many half-liter bottles of water can he fill?
Step-by-step explanation:
5 ÷ 1/2
A: Roman has a half liter jug of water. How many 5-liter bottles of water can he fill? .5 ÷ 5
B: Roman has a 10-liter jug of water. How many half-liter bottles of water can he fill?
10 ÷ .5
C: Roman has a 5-liter jug of water. How many half-liter bottles of water can he fill? 5 ÷ 1/2
The rate of each train of the northbound train traveled 10 miles per hour faster than the southbound train 26 miles per hour.
<h3>what is speed?</h3>
Speed is the time rate at which an object is moving along a path
Let the speed of southbound train is x miles/hour
so, northbound train has speed of x+10 miles/hour.
then, Speed of both train = Total distance/ total time
(x+10+x)=210/5
2x+10= 210/5
2x+10= 42
2x= 32
x= 16 miles per hour (southbound train)
northbound train: 16+10=26 miles per hour
