Hey there!
The answer to your question is 3480
There are two ways we can do this. I will show you both, so you know how to do it in the future:
The First Way ~ Parantheses First:
Step 1.) Add [tex]86[/tex] and [tex]34[/tex]
[tex]29(120)[/tex]
Step 2.) Multiply
[tex]3480[/tex]
The Second Way ~ Distribute First
Step 1.) Multiply [tex]29[/tex] and [tex]86[/tex]
[tex]29(34)+2494[/tex]
Step 2.) Multiply [tex]29[/tex] and [tex]34[/tex]
[tex]986+2494[/tex]
Step 3.) Add [tex]986[/tex] and [tex]2494[/tex]
[tex]3480[/tex]

A radioactive substance decays at a rate of 3.4% per day. If it starts at 200 grams, how
many days will it take for the substance to decay to less than 150 grams?
Answer: 9
Step-by-step explanation:
Since the percent is decaying, you subtract 3.4 from 100, which gets you 96.6
200(0.966)^9 gets you 146.5 which is less than 150

The scale used on a map is 5 millimeters represents 32 kilometers. How many millimeters represent 160 kilometers?
160 mm
25 mm
1 mm
800 mm
Answer:
25 mm
Step-by-step explanation:
Set up a proportion where x is the number of millimeters for 160 kilometers
[tex]\frac{5}{32}[/tex] = [tex]\frac{x}{160}[/tex]
Cross multiply and solve for x:
32x = 800
x = 25
So, 25 millimeters represent 160 kilometers
Answer:
25 mm

Simplify the inequality:
-12.4x+8x > -0.4x-5.2-2.7
Answer:
x < 1.975Explanation:
-12.4x + 8x > -0.4x - 5.2 - 2.7
Add similar elements: -12.4x + 8x = -4.4x
-4.4x > -0.4x - 5.2 - 2.7
Subtract -5.2 - 2.7: -7.9
-4.4x > -0.4x - 7.9
Multiply both sides by 10
-4.4x · 10 > -0.4x - 7.9 · 10
Refine
-44x > -4x - 79
Add 4x to both sides
-44x + 4x > -4x - 79 + 4x
Simplify
-40x > -79
Multiply both sides by -1 (Reverse the inequality)
-40x (-1) > -79 (-1)
Simplify
40x < 79
Divide both sides by 40
40x / 40 < 79 / 40
Simplify
x < ⁷⁹⁄₄₀
Turn the fraction into a decimal
