Step-by-step explanation:
<u>Step 1: Define</u>
3 - 4r ≥ 15
<u>Step 2: Solve for </u><em><u>r</u></em>
- [Subtraction Property of Equality] Subtract 3 on both sides: -4r ≥ 12
- [Division Property of Equality] Divide -4 on both sides: r ≤ -3
<u>Step 3: Compare</u>
- Substitute in <em>r</em>: -3 ≤ -3
This is true. -3 is less than <em>or equal to</em> -3.
Answer:
2x10^3
Step-by-step explanation:
(5x10^-3) is .005
(4x10^5) is 400,000
Multiply together and you get 2000
move the decimal to the right 3 times and you get 2x10^3
Answer:
10
Step-by-step explanation:
11/10.12/11.13/12........99/98.100/99
= 11.12.13....99.100/10.11.12.....98.99
=100/10=10
<span>The line with m=2 @ x=3
y-y1=2(x-3)
You need to find y1.
because 2 line intersecting @ x=3 , y coordinate is the same as well.
Let's find it:
y=2/3 *3 -2=0
So point of intersection is: (3,0)
The equation of the desired line will be:
y-0=2(x-3)
y=2x-6</span>
Okay 39 is 150% of what number? so like remember whenever you see percent you have to divide by 100
so let's start
First. we have 150% so let's divide 150%/100=1.5
Second. you will multiply 1.5*39= 26%
and you can also do it like easy way.
39/150=0.26
0.26/100=26
39 is 26% of 150
hope i help :p
