Answer:
12 times 5=60 not 70
Step-by-step explanation:
12(5+2y)=4y-(5-9y
60+24y=4y-5-9y
60+24y=-5y-5
29y+60=-5
29y=-65
y=-65/29 or y= about -2.38

-2x + 5 < 7
-2x + 5 < 7
<u> -5 -5 </u> deduct 5 from both sides
-2x < 2
<u>÷ -2 ÷ -2 </u> divide both sides by negative 2. Because of the division
x > -1 using a negative number, the sign is then reversed.
from < it becomes >.
The value of x should be greater than -1. It can be 0, 1, 2, so on...
To check: Revert back to the original sign which is <.
x = 1
-2x + 5 < 7
-2(1) + 5 < 7
-2 + 5 < 7
3 < 7
Answer:
1539 cubic meters
Step-by-step explanation:
Hello, I can help you with this
to solve need we will need these two equations
Step one
Remember
area of a circle

Also, the volume of the cylinder
Volume= area of the circle * height

Step 2
put the values into the equation
Let
diameter= 14 m
height = 10 m

I hope it helps,have a great day.
X+3y=14
-x. -x
3y=-x+14
Divide them all by 3
Y=-x/3+14/3
Y-intercept= 1/3
It should be about 22.55.
