(x + 7)/2 - (x + 4)/2 = (x + 7 - (x + 4)/2 = (x + 7 - x - 4)/2 = 3/2
Answer:
a=41.8 BC=2.8
Step-by-step explanation:
sin30/6=sinx/8
8*sin30=6sinx
4=6sinx
sin^-1(4/6)
angle a
cosine rule
bc^2=3^2 +5^2-2(3)(5)*cos30
BC^2=
BC=2.83

X is the number of weeks he is exercising starting summer
f(x) is number of total hours he exercised
Hello!
We need to find a denominator that both fractions can be. /63 works perfectly because 7x9 = 63. 3 x 9 = 27, and 4 x 7 = 28. Since 28/63 is bigger than 27/63, ramundus puts more money into car expenses.
Answer:
-2(3X-4) - X -3 = 33
-6X+8 - X -3 = 33
-7X +5 = 33
-7X = 33 -5
-7X =28
- X= 28÷7
-X = 4
SO X = - 4
