Sorry if I'm wrong
a = 10
this what I did
7 - 3 = 4 ÷ 0.4 = 10
Answer:
7
Step-by-step explanation:
7(x - 3) = 28 Given
7x - 21 = 28 Distributive property
7x - 21 + 21 = 28 + 21 Addition property of equality
7x = 49 Division Property of equality
7x/7=49/7
x = 7
How to solve: (15x10)-(3x3)
Answer(hopefully is right): 291
Answer:
θ = πk, 1.318+2πk, 4.965+2πk
Step-by-step explanation:
4sin(2θ) − 2sin(θ) = 0
8sin(θ)cos(θ) - 2sin(θ) = 0
2sin(θ)[4cos(θ)-1] = 0
2sin(θ) = 0
sin(θ) = 0
θ = πk
4cos(θ)-1 = 0
4cos(θ) = 1
cos(θ) = 1/4
θ ≈ 1.318+2πk, 4.965+2πk
Therefore, θ = πk, 1.318+2πk, 4.965+2πk
