Answer:
a=7
Step-by-step explanation:
6a-42=-7a+49
(add 7a to 6a)
13a-42=49
(add 42 to 49)
13a=91
(divide 91 by 13)
it is 26 give me branliest
<em>c. y = 1.25</em>
The equation for direct variation is
y = kx,
where k is the constant of proportionality.
We can use the given values of x and y to find k for this case.
y = kx
-10 = k * 40
k = -10/40
k = -0.25
The equation for this case is
y = -0.25x
Now we let x = -5 and solve for y.
y = -0.25(-5)
y = 1.25
Answer: c. y = 1.25
5, -25, 125, -625
A geometric sequence is where a number is divided or multiplied by same number continuously
in the third option the number are multiplied by (-5) continuously
92.4/3.3 = 28
Therefore, the number that 92.4 is 330 percent of, is 28.
