sorry wait please delete my answer I realized my mistake!
Answer:
m∠X = 29°
m∠V = 61°
m∠W == 90°⇒given
Step-by-step explanation:
∵ ΔXWV is right angle at W
∴ m∠W = 90°
∴ m∠X + m∠V = 180° - 90° = 90°
∵ m∠X = 2x + 5 and m∠V = 4x +13
∴ 2x + 5 +4x + 13 = 90
∴ 6x + 18 = 90
∴ 6x = 90 - 18 =72
∴ x = 72/6 = 12
∴ m∠X = 2(12) + 5 = 29°
∴ m∠V = 4(12) + 13 = 61°
Answer:
(b) 2.71828 . . .
Step-by-step explanation:
If your calculator does not have an 'e' button, you can have it compute e^1 using the exponential function button.

Like pi, 'e' is a transcendental number, a number that is not the root of any polynomial with integer coefficients.
Answer:
4/75
Step-by-step explanation:
you will get 5 and 1/3 percent equals (5 + 1/3) / 100 which is equal to 5/100 + (1/3) / 100 which is equal to 5/100 + 1/300. place both fractions under a common denominator. you will get 5/100 + 1/300 = 15/300 + 1/300 = 16/300. simplify the fraction to get 16/300 = 8/150 = 4/75
7(2x+5)=4x-9-x
14x+35=3x-9
11x = -44
x = -4
7(2*-4+5)=4*-4-9--4
7(-3)=-21
-21=-21. so it checks out and x = -4
