Mariulka [41]3 years ago

Answer:

x = -16

Step-by-step explanation:

52= 1/2x+15−3.25x−7

Combine 1/2x and −3.25x to get −11/4 x.

52= −11/4x+15−7

Subtract 7 from 15 to get 8.

52=−11/4x+8

Swap sides so that all variable terms are on the left hand side.− 11/4x+8=52

Subtract 8 from both sides.

− 11/4x=52−8

Subtract 8 from 52 to get 44.

−11/4 x=44

Multiply both sides by − 4/11

​ the reciprocal of − 11/4

​x=44(−4/11)

​Express 44(−4/11 ) as a single fraction.

x= 44(−4)

​Multiply 44 and −4 to get −176.

x= −176/11

​Divide −176 by 11 to get −16.

4.05 x 10^-2 Standard Form
defon

Answer:

0.0405

Step-by-step explanation:

10^-2 is the same as 1/100, so if you multiply 4.05 x 1/100, you get 0.0405.

Another way to think about it is by looking at the exponent -2.  You need to move the decimal point 2 spaces to the left -- and add zeroes to any spaces that don't already have numbers.

So if you start with 4.05, and move the decimal one space to the left, you get 0.405, and then you move it one more space, and you get 0.0405.

An automobile manufacturer is concerned about a possible recall of its best-selling four-door sedan. If there were a recall, the
andrew11 [14]

Answer:

0.27

Step-by-step explanation:

Suppose A is the event of defect in the brake system and B is the event of defect in the fuel system,

We have given,

P(A) = 0.25,

P(B) = 0.17

P(A∩B) = 0.15 ( the probability of defects in both systems simultaneously is 0.15 ),

We know that,

P(A∪B) = P(A) + P(B) - P(A∩B)

= 0.25 + 0.17 - 0.15

= 0.27

Hence, the probability that the defect is the brakes or the fueling system is 0.27.

Find the distance between -6 - 8
Viefleur [7K]

Answer:

2

Number line.

We start at -6 or -8.

If we start from -6, we will be going __ spaces to the left until we get to -8.

Or start from -8 and go __ spaces to the right until you get to -6.

Then count the spaces.

You'll get 2.

Identify an equation in point-slope form for the line parallel to y=-2/3x+8 that
UNO [17]

Answer:

\large\boxed{y+5=\dfrac{2}{3}(x-4)}

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

m - slope

Parallel lines have the same slope.

We have the equation in the slope-intercept form (y = mx + b)

y=-\dfrac{2}{3}x+8\to m=\dfrac{2}{3}

Put to the point-slope equation value of the slope and the coordinates of the point (4, -5):

y-(-5)=\dfrac{2}{3}(x-4)\\\\y+5=\dfrac{2}{3}(x-4)
