You can use substitution method
x - y = 7
(x+y)^2=289
So
Since the square of their sum is 298, their sum without being squared is the square root of 289.
Hence,
x - y = 7
x + y = 17
By subtracting you get the following:
= (0) -2(y)=-10
So -2y=-10
y=-10/-2
y=5
Now, plug in y in both equations to get x
x - (5) = 7
x + (5) = 17
Multiply each equation with its opposite y variables
(5) x - (5) = 7
(-5) x + (5) = 17
= 5x -25 = 35
-5x -25 = -85
Now subtract the equations
= 10x + (0) = 120
10x = 120
x = 120/10
x = 12
The Construction of the Enola Gay, would be your answer
Answer:
The sleds were a lot more controllable and predictable. The sleds also were used as rafts to float the large blocks around the construction sites.
Explanation:
<u>Answer:</u>
No one knew for certain the reason for the explosion.
Option: (A)
<u>Explanation:
</u>
- Though it was claimed by the American newspapers at the beginning that Spain was responsible for the sinking of USS Maine, the later investigation failed to find any evidence that pointed at Spain for the happening.
- The fact that there was a mine explosion beneath the bottom of the ship clarified that the reason for sinking was an active mine dropped in the waters close to the harbor.
- But the ones responsible for leaving the mine there have never been found.
