I solved it on paper & took a pic ^ here ya go!
Answer:
Hey there!
Step 1:
Write the equation
Step 2:
take 6 to other side to divide it with-42
after dividing 6 with -42 we will get -7
Answer:
It will take 25.7 minutes when they are working together
Step-by-step explanation:
Here, we want to know how long it will take both pipe working together to drain the tank
Let the volume of water to be drained be xL
for the first one, rate is
x/45 L/minutes
for the second x/60 L/minutes
Joint rate will be
x/45 + x/60 = 4x + 3x/180 = 7x/180
Now go get the time involved here, we simply divide the volume by the rate
That would be;
x divided by 7x/180
= x * 180/7x
= 180/7 = 25.7 minutes
Answer:
4
Step-by-step explanation:
Gradient is the same as slope to get your answer follow this formula y2 - y1 divided x2 -x1 in this problem it will look like this
4 - (-4) /1 - (-1) =
8 / 2 =
= 4
I hope this helps!!
Answer:
1.→∠CEA and ∠CEF are Adjacent Angles.Two Angles are said to be Adjacent if there is one common ray between these two angles and non common ray lie on opposite side of common ray. Here, CE is a common ray and AE and EF are non common rays. 2.→CD is a line. →∠CEF+∠FED=180°---Angle in a Linear pair →90°+∠FED=180° →∠FED=180 ...
