5 can go into 3 0 times so skip that, 5 can go into 34 6 times, put a 6 on top 6×5=30 34-30=4 bring the 0 down 5 can go into 40 8 times so put an 8 beside the 6 8×5=40 40-40=0

Hope this is understandable and helps

A straight line has slope 1 and goes through the points (0, -1) and (a,3). Find the value of a.

Gala2k [10]

$\bf (\stackrel{x_1}{0}~,~\stackrel{y_1}{-1})\qquad (\stackrel{x_2}{a}~,~\stackrel{y_2}{3}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{3}-\stackrel{y1}{(-1)}}}{\underset{run} {\underset{x_2}{a}-\underset{x_1}{0}}}~~=~~\stackrel{\stackrel{slope}{\downarrow }}{1}\implies \cfrac{3+1}{a}=1\implies 4=a$

The distance between Joshua's home and school is 800 m. Joshua takes 5 min to walk

Fynjy0 [20]

Answer:

= 0.38 m/s

Step-by-step explanation:

▪Total distance = 800 m

5 min = 100 m

▪Remaining distance = 800 - 100 = 700 m

20 min = 700 m

▪Total time taken = 20 + 10 + 5 = 35 min

If 1 min = 60 sec

What about 35 min = ?

= 35 x 60

= 2100 sec

▪Average speed = TD ÷ TT

= 800 ÷ 2100

= 0.38 m/s

Given m||n, find the value of x

Salsk061 [2.6K]

Answer:

x = 155º

Step-by-step explanation:

y = 25° {Vertically opposite angles}

x + y = 180 {Co-interior angles are supplementary}

x + 25 = 180

Subtract 25 from both sides

x = 180 - 25

x = 155°

If the perimeter is 284, what is the value of a? <br> Please show work xx

devlian [24]

Answer:

8

Step-by-step explanation:

Perimeter is 284 means the sum of the side measurements is 284.

That is, we have to solve:

$(6a+8)+(12a)+(10a-4)+(6a+8)=284$

Combine like terms:

$(6a+12a+10a+6a)+(8+0+-4+8)=284$

Simplify:

$34a+12=284$

Subtract 12 on both sides:

$34a=284-12$

Simplify:

$34a=272$

Divide both sides by 34:

$a=\frac{272}{34}$

Simplify:

$a=8$
