Answer:
a = 4
Step-by-step explanation:
So your goal here is to get the variable on just one side, so add 4a to both sides. This cancels out the 4a on of of the sides and puts a on the other side. The new equation is 8 = -2a + 4a. Combine like terms to get 8 = 2a. Divide both sides by 2 to get a = 4. You can check your work by replacing a with 4:
8 - 4(4) = -2(4)
8 - 16 = -8
-8 = -8
Since the final result is true, (-8 does equal -8,) a = 4.

help 8+x2=−12..im confused
Answer:
Step-by-step explanation:
No real solutions exist. Subtract 8 on both sides to get:
[tex]x^2=-20[/tex]
You cannot take the square root of a negative number without involving imaginary numbers.
Answer and Explanation
__________________________________________________________
-10__________________________________________________________
The answer is -10 because...
You need to multiply 2 by "x," and to find out what "x" is, we need to add...
[tex]2+-12[/tex]
__________________________________________________________
And if we add [tex]2[/tex] by [tex]-12[/tex], we get [tex]-10[/tex], which is our answer.
__________________________________________________________
and now, if we add [tex]-20[/tex] by [tex]8[/tex], we get [tex]-12[/tex], which is what the equation equals, and this is how we know it is correct.

It costs $16 for 8 specialty chocolates for Valentines Day. Find the unit rate 5 per item (how much for 1 chocolate).
Answer:
Unit Rate: 2$ per chocolate
If you're buying 5, it will cost $10
Step-by-step explanation:
Finding the unit rate:
16 ÷ 8 = 2
2 x 5 = $10
If you're talking about what happens if each chocolate cost $5 per item it would be
$5 x 8 chocolates = $40
I hope this helped! :)

John is creating a Thanksgiving display at the store where he works, using only canned pumpkin and canned green beans. He needs to maintain a ratio of pumpkin to green beans of 5 to 2. If he wants to use a total of 126 cans, how many cans of green beans should he use?
please help me lol
Answer:
90 pumpkin and 36 green beans
Step-by-step explanation:
Because there is a total of 7 parts (5+2) and I divided 126 by 7 and then put five of the 18ns (the quotient of 126 and 7) for pumpkins (so... multiply 18 by 5) then the other to times 18 is 36. And if you add them together, they equal 126.
Answer:
9 cans
Step-by-step explanation:
126/7=18
18/2=9
so 9 is the answer

Answer:
A.)555 in.^2
Step-by-step explanation:
When solving these types of things, I usually like to cut it up into smaller, easier to manage shapes.
You can cut that trapezoid into two triangles and one rectangle.
Since both triangles are the same size, you don't need to divide the base and height by two, so you'll get the area of both triangles combined (which saves some work).
We know the length of the rectangle and bases of the triangle combined is 44 inches, and that the length of just the rectangle is 30 inches, so we can just subtract 30 from 44 and divide it by two for the base of a triangle.
44 - 30 = 14
14/2 = 7
Now that we filled in the information not listed, we can finally solve:
The base of one triangle is 7 inches, and the height is 15 inches.
Now, we just multiple and divide it by 2 for one triangle (it would be 52.5 inches).
But, we don't need to divide it by two because both triangles are the same size, so we can just get the sum of the area of both triangles combined by skipping that step (because triangles are half a square and two of those triangles make a full square).
7 x 15 = 105
The area of both triangles combined: 105 in.^2
Next, we need to solve the area of the rectangle. This is easy considering all you have to do is multiply 15 by 30 (length times width).
15 x 30 = 450
The area of the rectangle: 450 in.^2
Now, the final step. Addition. All you need to do is add up all the sums, and you're done.
450 + 105 = 555
The area of entire figure: 555 in.^2
NOTE: the symbol '^' represents exponents, so when you see 555 in.^2, it means inches squared (or to the power of 2)

A company makes 100 bags.
41 of the bags have buttons but no zips.
32 of the bags have zips but no buttons.
22 of the bags have neither zips nor buttons.
How many bags have zips on them?
Answer:
37
Step-by-step explanation:
Bags that zips and no button = 32
Bags that have both zips and bags = 100-(41+32+22) = 5
Total bags that have zipz = 32+5 = 37
