First multiply and dstribute
a(b+c)=ab+ac
2(3x+2)=6x+4
6x+4=2x-1+x
add like terms
6x+4=3x-1
subtract 3x from both sides
3x+4=-1
subtract 4 from both sides
3x=-5
divide bothe sides by 3
x=-5/3
Answer:
A two story home might use translation to have both floors identical and most homes have windows of the same size and shape so they might also use translation. Sometimes buildings use reflection to make rooms opposite each other the same.
Step-by-step explanation:
Answer: since it doesnt say 620 is included , we can conclude that x>620, not x>=620 so the 8th week would be cut just short, so answer is 7
aka
fewer than 8 weeks
Step-by-step explanation:
1200-620=580
580/72.50=8
Answer:
<h2>15.3 gallons</h2><h2 />
Step-by-step explanation:
ratio and proportion
<u>420 miles </u> = <u> 357 miles</u>
18 gallons x gallons
420 (x) = 357 (18)
x = 6426 / 420
x = 15.3 gallons
<span>Let </span>
<span>X= the altitude of the lighthouse above sea
level= 80 ft</span>
A = the angle of depression
Y= the distance of the boat from the lighthouse= 400 ft
tan A=X/Y------------------ >
80/400=0.2
arctan (0.2)=11.31 degree
The answer is the angle of depression is 11 degree
