X = -4.
explanation:
21+3x=3(-x+3)-12
21+3x=-3x+9-12
21+6x=9-12
21+6x=-3
6x=-24
x=-4
Answer:
Step-by-step explanation:
y = mx + b
in this form, the constant of proportionality is also known as the slope....and it can be found in the m position
y = 3x.....is actually y = 3x + 0....so the slope (constant of proportionality is gonna be 3
A)
91/100
we cannot simplify this
b) 12/100 = 6/50
cannot be simplified further
c) 6/100 = 3/50
d) 93/100
cannot be simplified
e) 62/100 = 31/50
f) 14/100 = 7/50
g) 70/100 = 7/10
h) 400/100 = 4
when something is in percentage that means it is some part of 100% that is why we divide by 100.
the side lengths of this special triangle are in the ratio 1:1:sqrt2
so u and v are both equal to 8 units
it should be 14 becuse 7 times 2 is 14 so x=14 i took the test
