Answer:
Let n and n+4 be the numbers. Then:
n² + 3(n+4)=66
n²+3n-54=0
(n+9)(n-6)=0
n=6 or -9
n+4=10
Assuming positive integers only, the numbers are 6 and 10…..
Step-by-step explanation:
100% right
Answer:
255 m
Step-by-step explanation:
From the given question, the surface of the water body is the reference point. And this point is assumed to be 0, so that any distance above it is positive, and any distance below is negative. This is synonymous to the number line system.
Thus,
For the aircraft, its height = +200 m
For the submarine, its depth = -55 m
So that the difference between the submarine and aircraft can be determined as;
200 - (-55)
= 200 + 55
= 255 m
The distance between the submarine and aircraft is 255 m.
Answer:
127 bags.
Step-by-step explanation:
20 yd x 19 yd = 380 yd.
380 yd / 3 bags = 126.666666667
To round it, 127.
<span>The first equation is
x + y = 27
For the second equation, there are twice as many girls (y) as boys (x), so you write:
y = 2x
Now you have a system of equations:
x + y = 27
y = 2x</span>
Question:
its asking about the difference between them
Answer Step:
since we gotta find the difference we going to subtract in order to find the difference -59 - -27
answer should be -32
correct me if im wrong.
