Let a = the larger number
<span>b = the smaller number </span>
<span>a + b = 16 </span>
<span>3a - b = 72 </span>
<span>a = 16 - b </span>
<span>3(16 - b) - b = 72 </span>
<span>48 - 3b - b = 72 </span>
<span>-4b = 24 </span>
<span>b = -6 </span>
<span>a = 16 - (-6) </span>
<span>a = 22 </span>
<span>The two numbers are: </span>
<span>22 and -6</span>
Good morning,
Answer:
<h2>d = 56</h2><h2 />
Step-by-step explanation:
18d = 7×144
18d = 1 008
d = 1 008÷18
d = 56.

Answer:
225 inches²
Step-by-step explanation:
Let the length be l and width be w
Condition 1
2l+2w=68 (Perimeter=68)--------(i)
Condition 2
l=3w-2 ---------(ii)
Putting equation (ii) in (i)
2(3w-2)+2w=68
6w-4+2w=68
8w-4=68
8w=68+4
8w=72
dividing both sides by 8
w=9 inches
now putting w=9 in (ii)
l=3(9)-2
l=27-2
l=25 inches
Now
Area of rectangle = l × w
=9 × 25
=225 inches²
In miles 365 million miles or 365,000,000
in km, 588 million km or 588,000,000
so
scientific notation=(number less than 10 and greater than or equal to 1) times 10^n
so
we need to move the decimal point 8 spaces to the left
to compensiate for that, we multiply by 10⁸ which will move it 8 to the right
so
365,000,000 mi=3.65 times 10⁸ mi
588,000,000 km=5.88 times 10⁸ km
those are the distances in scientific notation
Answer:
The points are (5,1) which are (x,y)
That being said the 1=3(5)+2
1=17
