Answer:
the numbers are 43 and 15
Step-by-step explanation:
Let the numbers are x and y
x+y=58
x-y=28
from that two equations,
2x=86
x=43
substitute x value in any equation we will get ,
y=15
To round a number to the nearest tenth, look at the next place value to the right (the hundredths). If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right.
The answer is A. Because if you subtract 3 from 23 it will be 20 and 20 divided by 2 is 10
Answer:
The area and the perimeter of the square barn which has each side 9 meters long is 81 m² and 36 m.
Step-by-step explanation:
In the figure we have three parallel lines cut by two transversals
The theorem stares:
If two or more parallel lines are cut by two transversals, then they divide the transversals proportionally.
Applying this theorem we have:
![\frac{4}{x} =\frac{6}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7Bx%7D%20%3D%5Cfrac%7B6%7D%7B5%7D%20%20)
To solve for x we cross multiply
6x=20
Dividing both sides by 6 we have:
![x=\frac{20}{6} =\frac{10}{3} =3\frac{1}{3}](https://tex.z-dn.net/?f=%20x%3D%5Cfrac%7B20%7D%7B6%7D%20%3D%5Cfrac%7B10%7D%7B3%7D%20%20%3D3%5Cfrac%7B1%7D%7B3%7D%20%20)
The second option x=
is the right answer
