After this step:
1. 8+x=7 multiply both sides by -1
2. x=-7-8 move the constants to the right
3.x=-7-8 Calculate
4. x=-15
Answer:
It isn't hard to find out if your working 1 hour a day for 10 days you would have 130 dollars
Step-by-step explanation:
So take the extra 3 off right? 10x10 is 100 so then 10x3=30 100+30=130
Answer:
Step-by-step explanation:
the direct variation is will be y varies directly as x and
mathematically
y∝ x
y = kx ........................................ wher k is the constant of proportionality
k = y/x
given that y = 2
x = 8
k = 2/8
k = 1/4
c ≈ 16.7 ( to 1 dec. place ) → d
since triangle ABC is right use the cosine ratio to find c
cos33° = =
multiply both sides by c
c × cos33° = 14 ( divide both sides by cos33° )
x = ≈ 16.7 ( to 1 dec. place )
Answer:
3/2
Step-by-step explanation:
formula k = y/x
comes from
y = kx
k = constant of variation
when y = 3 , x = 2
k = 3/2
