7x+2y=11
-2x+3y=29
How do you solve this problem?

Answers

you subsitute 11-2y/7 when you do that you get -2 11-2y/7 +3y=29: y=9 isolate y -2 11-2y/ +3y=29 y=9
x= 11-2 . 9/7 x= -1
Y=9 X=-1

X=1 y=2 for the first one

If the probability that the Seahawks will win any given game is 0.6, the probability that they will lose three games in a row is _? Write your answer as a decimal.

Answers

-- If the probability of winning any given game is 0.6,
then the probability of losing that game is 0.4 .

The probability of losing Game #1 = 0.4
The probability of losing Game #2 = 0.4
The probability of losing Game #3 = 0.4

The probability of all 3 events occurring = (0.4) · (0.4) · (0.4)

= (0.064) = 6.4% .

Difference of numbers. The larger of two integers is 8 less than twice the smaller. When the smaller number is subtracted from the larger, the difference is 17. Find the two numbers.

Answers

let's call the numbers x (the bigger) and y (the smaller)

The larger of two integers is 8 less than twice the smaller. this means:

x=2z-8
When the smaller number is subtracted from the larger, the differenceis 17.

This means: x-z=17.

i'll insert
2z-8

instead of x, since it's equal to it:
2z-8-z=17

2z-z is just z:
z-8=17

so

z=25.
and x must be 25+17=42

let's check:The larger of two integers is 8 less than twice the smaller.
twice the smaller is 50, and yes, 42 is 8 smaller than 50, it's correct!

so the two numbers are 25 and 42

What is the solution to the linear equation?

4b + 6 = 2 – b + 4

Answers

Answer:

The answer is b=0

Step-by-step explanation:

Add b to both sides

5b+6=2+4

combine like terms

5b + 6= 6

subtract 6 from both sides

5b=0

divide

b=0

hope this helped

Answer:

b = 0

Step-by-step explanation:

1. Add b to each side.

4b+b+6 = 2+4

= 5b+6 = 6

2. Subtract 6 from each side.

5b+6-6 = 6-6

= 5b = 0

3. Divide each side by 5.

5b/5 = 0/5

b = 0

For a wall of a given material and of a fixed surface area, the rate of heat loss by conduction through the wall is inversely proportional to the thickness (T) of the wall, and directly proportional to the temperature difference (d) across the wall. The rate of heat loss could be given by which of the following expressions?A. 2d/T
B. 2 T/d
C. 2d + ½ T
D. 2(d + ½ T)
E. T/d

Answers

the answer is A .2d/T
Since d is directly proportional to the heat lost it should be the numerator
since T is inversely proportional to the heat lost it shoudl be the denormirator
that is 1/T ; 2 is the constant
the actual formula is R = kd/T
