Answer:
Infinitely many solutions. Each real number is a solution of this equation.
Step-by-step explanation:
-5 + (-5r) + 10 = -5r + 5
5 - 5r = -5r + 5 <em>add 5r to both sides</em>
5 = 5 TRUE
We can find the volume of any rectangular prism by simply multiplicating its height, length and width.
Also, lets change that 6 1/4 to 6.25, or 25/4 if you like. I’m gonna use 6.25.
If we take volume as “V”, then:
V = L * W * H
V = 3ft * 6.25ft * 14ft
V = 262.5 ft^3 (Its ft cubed because we multiplied by ft three times.)
Answer:
12
Step-by-step explanation:
so $8.06 / .65 = 12.4 but you cannot buy .4 of a bagel so the answer would just be 12
Answer:
Speed of plane in still air = 135 km/h
Speed of wind = 23 km/h
Step-by-step explanation:
Given that:
Speed of plane with the wind = 158km/h
Speed of plane against the wind = 112km/h
Let,
x be the speed of plane
y be the speed of wind
According to given statement;
x+y = 158 Eqn 1
x-y = 112 Eqn 2
Adding Eqn 1 and 2
Putting x = 135 in Eqn 1
135+y = 158
y = 158-135
y = 23
Hence,
Speed of plane in still air = 135 km/h
Speed of wind = 23 km/h
Um this is a chemistry question, you should probably put it in the chemistry section.
