Answer:
e,q,u,a,t,i,n & EQUATIONYL
Step-by-step explanation:
K∩L:
First write both the words, equation and inequality down.
E Q U A T I O N
I N E Q U A L I T Y
You can see EQUATIN repeats in both of the words.
K∪L:
First write both the words, equation and inequality down.
E Q U A T I O N
I N E Q U A L I T Y
This time just write down all the letters EXCEPT the ones that repeat. EQUATIONYL
So 6+3 is 9 right? So let's just say it's 9:37 with a 45 min ride. 60 minutes are in a hour. 60 - 37 = 23. We have 23 minutes left until 10:00. 45- 23 = 22. Therefore it'd be 10:22 p.m.
Step-by-step explanation:
1 mile=5280 feet
2 miles=10560 feet
3 miles=15840 feet
3.5 miles=18480 feet
Answer:
<u>1 mile= 5280 feet</u>
3.5 miles= x
Writing an equation is the easiest way to figure this out.
b = boys, g = girlsb = 3/4g35 students = g + b35 = g + 3/4g35 = 7/4g35/7/4 = g20 girls35 - 20 = b or 3/4(35) = b15 boys
X+y=2 (label equation one)
x-y=4 (label equation two)
y=-x+2 (equation one rearranged, label this equation equation three)
sub 3 into 2
x-(-x+2)=4
x+x-2=4
2x-2=4
2x=6
x=3
sub x=3 into equation one
3+y=2
y=-1
therefore x=3 and y=-1
