The first second and third
Answer:
1. $106.20
2. $17.73
3. $372.59
4. $57
Step-by-step explanation:
1. Addition 97.95+8.25=106.20
2 multiplication. 1.97x9=17.73
3. Subtraction 447.59-75.00=372.59
4. Division. 285/5=57
You're answer will be 20x+y-3 because you can distribute 4x to 5x and when you do that, you multiply. But you can't distribute 4x to y or -3, so you leave them alone.
hello
we are going to solve this question via substitution method
put equation 2 into equation 1
put y = 11 into equation 1 or 2
with equation 1
put y = 11
fro the calculations above, the solutions to the equations with the value of x and y are (13) and (11)
Step-by-step explanation:
Given that
∆ABC is a right angled triangle
angle B = 90°
BC = 50 units
Hypotenuse (H) = AC
AC = 100 units
We know that
Cos A = Adjacent side to angle A / Hypotenuse
→Cos x = BC / AC
→Cos x = 50/100
→Cos x = 1/2
→Cos x = Cos 60°
.°. x = 60°
Hence, the value of “x” is 60°
