Answer:

$x=\frac{y+3w}{7}$

Step-by-step explanation:

The given equation is

$y=7x-3w$

We need to solve this equation for x.

Isolate variable x to solve this equation for x.

Add 3w on both sides.

$y+3w=7x-3w+3w$

$y+3w=7x$

Divide both sides by 7.

$\frac{y+3w}{7}=\frac{7x}{7}$

Cancel out common factors.

$\frac{y+3w}{7}=x$

Interchange the sides.

$x=\frac{y+3w}{7}$

Therefore, the formula for x is $x=\frac{y+3w}{7}$ .

How to solve shaded regions on a trapezoid is simple.
First find the area of the whole trapezoid, or W but it already gives us that as 21.66 in squared.
Next, find the area of the non shaded region, or NS.
3.8*4.6=17.48 in
Lastly, subtract the NS from the W.
21.66 -17.48 =
NS= 17.48 in squared.
W= 21.66 in squared.
S= 4.18 in squared.

The answer is B- 4.18 in Squared

Find the solution of this system of equations.

beks73 [17]

x= -8 + y
-9x + 6y= 9

substitute x= -8 + y into -9x + 6y= 9

-9x + 6y= 9
-9(-8 + y) + 6y= 9
72 - 9y + 6y = 9
-3y = -63
y = 21

x= -8 + y
x= -8 + 21
x = 13

solution (13, 21)

Given that -5 is a zero of the function f(x) = x^3 + x^2 - 14x + 30 find the remaining zeros

vampirchik [111]

Since the factors are (x+5)(x^2-4x+6)

the zeros would be 2+i√2 and 2−i√2

FIRST GETS BRAILIEST Michael finds that 35 customers at his grandfather's grocery store use a coupon. To simulate the behavior

Nataly [62]

Answer:

$\frac{1}{3}$ .

Step-by-step explanation:

We are given that,

1, 2, 3 represents someone using a coupon and 4, 5 represents someone not using a coupon.

Now, the results out of 15 trials of the experiment are given to be:

43454, 24511, 55555, 43453, 55315, 25215, 32235, 43311, 11154, 13342, 42514, 13223, 44215, 45313, 13324.

Since, we can see that, the only possibilities where 4 or more customers use coupons are:

32235, 43311, 13342, 13223 and 13324.

That is, out of 15 trials, there are total 5 trials in which 4 or more customers use coupons.

Thus, the probability of 4 or more customers using a coupon is $\frac{5}{15}$ = $\frac{1}{3}$ .

Hence, the required probability is $\frac{1}{3}$ .
