Please, in the future, post just one problem at a time.

Looking at Problem #1:  The line intersects the y-axis at (0,-3) and intersects the x-axis at (1,-1).  At least, this is what I see; your graph is small.
                                                                           -3-[-1]
The slope of that line is then  m = rise / run = ------------ = +2.
                                                                            0 - 1
                                       [change in y]
Slope = m = rise / run = --------------------
                                        [change in x]

First, simplify each one.

9.98 x 10^6 = 9980000

7.3 x 10^7 = 73000000

Next, subtract the freight from the aircraft

73000000 - 9980000 = 63020000

Round the decimal point to the first significant digit, and place the amount of place values the decimal point moved to the left as a power sign, over 10.

63020000 = 6.302 x 10^7

6.302 x 10^7 is your answer

hope this helps

6/7 divided by 12/14 please show the work
Minchanka [31]

Answer:

1

Step-by-step explanation:

When dividing one fraction by another, the best way to solve it is to multiply by the reciprocal. The reciprocal just flipping the fraction over. So you would leave the 6/7 and the multiply by 14/12( because you are multiplying by the reciprocal). When you do that, you then can just multiply the top and the bottom to form one fraction. The numerator is 6*14 = 84, and the denominator is 7*14 = 84. So you are left with 84/84 which anything over itself is equal to one.

Hope this helps!

angle and angle b are complentary angles. if angle a = (2x-5) and m angle b = (5x+4) then find the measure of angle a
iris [78.8K]

complementary angles = 90

2x-5 + 5x+4 = 90

combine like terms

7x-1 =90

7x = 91

divide by 7

x =13

angle a

2x-5

2*13-5

26-5

21

Angle a: 21

Need help again math 7th grade ​
Olenka [21]

Answer: 1/2 as a fraction

.5 as a decimal

Step-by-step explanation: The probability of them rolling a number would be 3/6 or simplified 1/2 because if there is a 6 sided dice the denominator would be 6 and there are 3 odd numbers on the dice which are 1,3,and 5 so if u have to simplify it would be 1/2 if not 3/6. Also 1/2 as a decimal would be .5
