Step-by-step explanation:sorry I didn’t explain the whole thing I’m really tired

Answer:

See below

Step-by-step explanation:

1. Perimeter is the sum of all sides.

(x+4)+(x+4)+(2x-8)+(2x-8)

(x+4)+(x+4) = 2x+8

(2x-8)+(2x-8) = 4x-16

2x+8 + 4x-16 =

6x-8

2.

4x-5 Sat

3x-10 Sun

(4x-5)-(3x-10)

4x-3x = x

-5--10 = 5

x+5

3. Total, so add

8x+16 Sat

7x-9 Sun

(8x+16) + 7x-9

8x+7x=15x

16-9=7

15x+7

Answer:

B,b‒a is a positive.

Step-by-step explanation:

if a=‒x x=rational number

b=x

let's see these by examples

A,a‒b is a positive, ‒x‒x=‒2x (the answer is negative) so this is wrong

B,b‒a is a positive, x‒(‒x)=x+x=2x (the answer is positive)so this is correct answer

C,b+(‒a) is a negative,x+‒(‒x)=x‒(‒x)=x+x=2x(the answer is positive)so this is also wrong

i hope it helps you

Step-by-step explanation:

y-b=m(x-a)

y--10=1/6(x--6)

y+10=1/6(x+6)

6y+60=1(x+6)

6y+60=1x+6

6y=1x-54

y=1/6x-54/6

y=1/6x-9

The  equation of line is y= 1/6x - 9.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

slope= 1/6

and, passes through (−6,−10)

Now, using slope intercept form

y- a =m (x- b)

y - (-10)= 1/6(x -(-6))

y + 10= 1/6( x + 6)

y + 10 = 1/6x + 1

y= 1/6x - 9

Hence, the equation of line is y= 1/6x - 9.

Answer:

6.8 km/hr

Step-by-step explanation:

If Sara ran 34 km in 300 minutes, then, in one hour, she would run

=> 34 : 300

=> ? : 60

=> 300 / 5  : 34 / 5

=> 60 : 6.8

So, if she travels 6.8 km in 60 minutes, her speed is 6.8 km/hr

Answer:26

Step-by-step explanation:

Answer:  [tex]b = \frac{y+6}{d}[/tex]

Step-by-step explanation:  To isolate b, begin by adding 6 to both sides

y=bd-6

y + 6 = bd - 6 +6   This "cancels" 6 on the right leaving

y + 6 = bd   Divide both sides by d

(y + 6)/d = bd/d   This cancels d on the right leaving

(y + 6)/d = b   To neaten this up rewrite (using the equations tool below)

[tex]b = \frac{y+6}{d}[/tex]

Answer:

70 + 2 + 0.3 + (-30) + (-9) + (-0.1) = 70 + (-30) + 2 + (-9) + 0.3 + (-0.1)

Step-by-step explanation:

Answer:

When you add the left side of the equation, you get 33.2 because 70-30 is 40, 40+2 is 42, 42-9 is 33, 33+0.3 is 33.03, 33.3-0.1 is 33.2.

Step-by-step explanation:

Answer:

[70 + (-30)] + [2 +(-9)] + [0.3 + (-0.1)]  

=  

40 + (-7) + 0.2

=  

33 + 0.2

=  

33.2°F

Answer:

Your answer would be C.

Step-by-step explanation:

The expression that can be used to determine the distance he walked each minute is x = 12/(3/4) miles option (A) is correct.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

Kevin walked Three-fourths of a mile in 12 minutes. Assuming he walked at a constant speed the entire time.

As we know,

The distance = speed x time

Speed is constant

distance ∝ time

3/4 ∝ 12

1 ∝ x

Here x is the distance traveled each minute

3/4 = 12/x

Or

x = 12/(3/4)

1/4 = 4/x

x = 16 miles

Thus, the expression that can be used to determine the distance he walked each minute is x = 12/(3/4) miles option (A) is correct.
