elena-s [515]
We want to use elimination to solve
y = 0                     (1)
x + y = 40             (2)

Multiply (1) by -1 to eliminate y.
-y = 0                    (3)

Add (2) and (3).
x + y + (-y) = 40 + 0
x = 40

Answer: Multiply by -1.

How do you work this problem
ankoles [38]
 An easy way is to do it, if you get confused by multiplying fractions, is by turning the fractions into decimals. Since you are trying to find N you want to multiply the 1/5 by the 1/3.

1/5 = 0.2

1/3 = 0.33333333333333333333333333333333

 if you multiply those you get 0.06666666666666666666666666666667 which when put into a fraction it equals 1/15



but if you don't want to do that just try to remember that you want to get by itself. and when multiplying fractions in this situation the bottom numbers only matter.. so 5 x 3 = 15  1/15

would you like me to put it in a document to show you?

What is the slope of the line?
jarptica [38.1K]

-3/2

slope = rise/run

We can use the two points to calculate rise (y value change) and run (x value change)

slope = (-6)/4 = -3/2

Angle DEF is an inscribed angle on a circle, and m O 48°<br> O 96°<br> O 132°<br> O 24°
bija089 [108]

∠24°

What is an inscribed angle in a circle?

Inscribed angles are angles whose vertices are on a circle and that intersect an arc on the circle. The measure of an inscribed angle is half of the measure of the intercepted arc and half the measure of the central angle intersecting the same arc.

given that intercepted arc = ∠48°

The intercepted arc is the arc that is inside the inscribed angle and whose endpoints are on the angle.

If the intercepted arc is twice the size of the inscribed angle, then the inscribed angle is half the size of the intercepted arc. So if the intercepted arc is 48 degrees, the inscribed angle is 48 / 2 = 24 degrees.

Ricky rides his bike 12 miles every day he stops 7 miles to rest write and solve an equation to find out how much further he has
kondor19780726 [428]
<h3><u>Question:</u></h3>

Ricky rides his bike 12 miles every day. He stops after 7 miles to rest. write and solve an equation to find out how much further he has to ride

<h3><u>Answer:</u></h3>

Ricky has to further ride for 5 miles

<h3><u>Solution:</u></h3>

Given that, Ricky rides his bike 12 miles every day

Let "x" be the remaining distance in miles he has to ride further

Total distance = 12 miles

Also, given that he stops after 7 miles to rest

Therefore, already covered distance = 7 miles

Therefore, we can frame a equation as,

remaining distance + already covered distance = total distance

x + 7 = 12

Solve the above equation for "x"

x = 12 - 7

x = 5

Thus Ricky has to further ride for 5 miles
