We can just plug in the values of x = 2 and y = 4 into the expression 4x+y to get 4*2 + 4 = 8 + 4 = 12.
for 2y-x = 2*4 - 2 = 8 - 2 = 6
Answer:
23/25 when reduced to the simplest form.
Step-by-step explanation:
write down the number as a fraction of one
0.92 = 0.92/1
so we multiply both numerator and denominator by 100
Then 0.92/1 = ( 0.92x100) / ( 1x100)
= 92/100
Now reduce the numerator and denominator by GCD between in this case
GCD ( 92,100) = 4
so, 92/ 4
100/ 4
=23/25
Answer:
Always
Step-by-step explanation:
the product of
![{a}^{2} - {b}^{2} = (a +b)(a -b )](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%20-%20%20%7Bb%7D%5E%7B2%7D%20%20%3D%20%28a%20%2Bb%29%28a%20-b%20%29)
is always same
42.081 * 99.91 ≈ 42 * 100 ≈ 4200

Answer:
C
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
The angle between the tangent and AC is right, that is 90°, thus
x = 180° - (90 + 22)° = 180° - 112° = 68° → C
