Step-by-step explanation:
25 x 18 x 4, gives you 1800 square inches, divide 1800 by 200 and you get 9
Answer:
x=15
Step-by-step explanation:
This is a simultaneous equation
2x-3y=45 ------------------------------ equation i
x+y=10 -------------------------------equation ii
from equation ii
x+y=10
make x the subject of the matter
we have,
x=10-y
in equation i
substitute x for 10-y
2x-3y=45----------------------i
since x=10-y
we have,
2(10-y) - 3y=45
20-2y=3y=45
collect like terms
-2y-3y=45-20
-5y=25
divide both sides by -5
we have y=-5
substitute y for-5 in equation i
x+y=10
x+-5=10
collect like terms
x=10+5
x=15
therefore
x=15
X = 2002, y = 2003
x + y = 9316
y = 2.35x
x + 2.35x = 9316
3.35x = 9316
x = 9316 / 3.35
x = 2780.8 rounds to 2781 <=== year 2002
y = 2.35x
y = 2.35(2781)
y = 6535.3 rounds to 6535 <== year 2003

Answer:
Step-by-step explanation:
Consider the answer choices.
3 & 5: product 15, sum 8 . . . . product > sum
2 & 2: product 4, sum 4 . . . . product = sum (not >)
1 & 4: product 4, sum 5 . . . . product < sum (not >)
Of the offered choices there are two counter examples:
2 and 2
1 and 4
_____
<em>Additional comment</em>
Chances are that the preferred answer is 1 and 4.
1 and <anything> will be a counterexample.
