Step-by-step explanation:

The points on a horizontal line will always have the same y coordinate.

Since the point (-8, -7) is on this horizontal line, the y coordinate is -7.

So the equation of the horizontal line is y = -7.

What is the value of x in the equation -6/7= -×/84?

pantera1 [17]

-6/7 = -x/84

84/7 = 12

12(-6) = -72

x = -72

So, -6/7 = -72/84 because -72/84 simplifies to -6/7

Y=-1,X+2y=-6 solve by substitution show all work

aev [14]

Answer:

$x=-4$

Step-by-step explanation:

$x+2y=-6$

$y=-1$

_________

$x+2\left(-1\right)=-6$

$x-2\times \:1=-6$

Multiply: 2*1= 2

$x-2=-6$

Add 2 to both sides:

$x-2+2=-6+2$

$x=-4$

ammar hikes 23/4 miles of nature trail in 1 hour and 15 min .How many miles of trail does ammar hike per hour? pleas help me to

telo118 [61]

23/4 miles is as much as 5 3/4 miles. We can also write it as a decimal, because 5 3/4 = 5,75 miles.

If Ammar hikes 5,75 miles in 1 1/4 hour, then we need to find out what distance does he hike in 1/4 hour (15 minutes). To do that we can just divide 5,75 by 5 (because dividing 1 1/4 by 5 will give us 1/4 we're looking for).

5,75 / 5 = 1,15

It means that in one hour Ammar hikes 5,75 - 1,15 = 4,6 miles.

We can also write it as a fraction:

4,6 = 4 6/10 = 4 3/5 = 23/5 miles

Just pick whichever form you like :)

Answer:

Step-by-step explanation:

hypotenuse (h) = 9.4

base(b) = 1.9

cos x = b/h

cos x = 1.9/9.4

x = cos ^-1 ( 1.9/9.4)

x = 78.3°

hope it will help :)
