x+y = 6.1
x-y = 1.6
2x = 7.7
x = 7.7/2
x = 3.85
y = 6.1-3.85 = 2.25
numbers are 2.25 and 3.85
Answer:
15. Yes, it is larger than 14.
Step-by-step explanation:
In this problem,
×25,
25 is divided by 5 and the remainder is 5, So,
3×5 = 15,
Now,
15 > 14,
So, the product of ( × 25) is greater than 14
Answer:
45°
Step-by-step explanation:
The sum of a triangle's angles is 180°.
Let's take the triangle FIG and try to express its angles in function of x.
● < F :
< F +3x = 180 => <F = 180 -3x
● < G :
IK and GH are paralell. IG is crossing them.
x and G are interior alternate angles so they have the same size.
< G = x
● < I :
We khow that < F = 180 -3x and < G = x
< I = 180-(< F + < G )
< I = 180 - ( 180-3x +x)
< I = 180 -(180-2x)
< I = 180 -180 +2x
< I = 2x
■■■■■■■■■■■■■■■■■■■■■■■
< F = 180 -3x
< G = x
< I = 2x
< I + > I + x + 2x = 360
2x + 180-x +3x = 360
4x + 180 = 360
4x = 180
x = 45°
●●●●●●●●●●●●●●●●●●●●●●●
Let's verify :
< F = 180 - 3*45 = 45 °
<G = x = 45°
< I = 2x = 90°
90° +45°+45° = 180°
So it's true.
Answer:
<u>18 of the books are science fiction.</u>
Step-by-step explanation:
24/4 = 6
Science fiction - 6+6+6 = 18
Not science fiction - 24 - 18 = 6
Anwser : n = -2
Combine Like Terms
Add 4n to both sides
Subtract 3 from both sides
A = n= -2
