Answer:
You want to solve for x, the first thing you need to do is distribute
The 2 through the x+4 then the other 2 through the -8-x
2(x+4)= 2x+8
2(-8-x)= -16-2x
2x+8=-16-2x-2x (combine like terms on the right side)
2x+8=-16-4x (now subtract 8 from each side)
2x=-24-4x (8-8=0, -16-8=-24) (now add 4x to each side)
6x=-24 (-4x+4x=0, 2x+4x=6x), (divide each side by 6)
x=-4 (6/6=1, -24/6=-4)
x=-4
Hope this helps ;)
Y=35(0.35) is exponential decay
Answer:
x=12
Step-by-step explanation:
This is a right triangle, so the Pythagorean theorem can be used. The Pythagorean theorem states that
where C is the hypotenuse and a and b are legs. In this question, we are given a and C. So, plugin 13 for C and 5 for a and solve for b. Once you rearrange the equation you get,
. Next, solve what is under the root to get,
. Finally, square root 144 for the final answer b=12.
Answer:
of a loave of bread per person
Step-by-step explanation:
<u>Step 1: Convert words to expressions
</u>
Seven people in Luisa's Family = <em>7 people
</em>
Four loaves of cinnamon bread = <em>4 loaves
</em>
<u>Step 2: Divide people from loaves
</u>
4 loaves / 7 people <- This means they are splitting 4 loaves of bread between 7 people
