Answer:
Number of stars: 2+2+2+2+2+2
=6×2
Step-by-step explanation:
The stars are added in pairs of two. The pair that is 2+2+2+2+2 is five groups of 2 or 2 groups of five.
Since another pair of two wad added, there is one more pair. Instead of 5×2
Which means 5 groups of 4, it is not 6 groups of 2. I hope I helped you! Have a good day :3
For the function
y = cos(1/2 x)
The x-intercept can be calculated by equating the function to zero and solving for x. So,
y = cos(1/2 x) = 0
1/2 x = arc cos 0
1/2 x = 90° +180°n
x =2 (90° +180°n)
x = 180° + 360°n
or converting to radians
x = (180° + 360° n)(π/180°)
x = π + 2π n
where n is any whole number
if n = 0
x = π
u have to multiply all the sides and
Answer:
16x+7 is equivalent
Step-by-step explanation:
16x-10 + -2+19
16x -10 + 17
16x+7
(Cannot add 16x and 7 because they are not the same variable)

Answer:
x=16; y=24
Step-by-step explanation:
for (x,23), 23=0.5x+15
x=16
for (18xy), y=0.5*18+15=24
