Answer:
x is 10.
Step-by-step explanation:
3x + 12 = 42
Subtract 12 from both sides
3x = 42 - 12
Subtract 12 from 42 to get 30
3x = 30
Divide both sides by 3
x = 30/3
Divide 30 by 3 to get 10
x = 10

Mr. Bates and Ms. Psenicska like playing Pokemon. Mr. Bates has 3 packs of cards plus 2 other cards. Ms. Psenicska has 6 packs of cards plus 8 other cards. White an algebraic expression to represent this scenario.
Answer:
The only algebraic expressions we can find here are the ones for the number of cards that Mr. Bates and Ms. Psenicska have.
We know that Mr. Nates has 3 packs of cards, plus 2 other cards.
If each pack of cards has N cards, then the total number of cards of Mr. Nates is:
Mr. Nates = 3*N + 2
And Ms. Psenicska has 6 packs plus other 8 cards, then she has a total of:
Ms. Psenicska = 6*N + 8
These two are the only expressions we can make with the given information.

Your textbook has a length of 30 cm, width of 25 cm, and a height of 4 cm. What is its volume?
Hey there! The answer you're looking for is 3000 centimeters^3. If we take the first number, 30 cm, and multiply it by the second number, 25 cm, we're left with 750 cm^2. We use the last digit to multiply the 750 cm^2 into 3000 cm^3. Hope this helped!

solve for t. -1 (t + 8) = -7.1 brainly
t=___?
(Please hurry!)
Answer:
.9
Step-by-step explanation:
-1(t+8) = -7.1
PEMDAS
So times the parenthesis by -1
-t - 8 = -7.1
Add the 8 to itself to get rid of it
Then since you added it on the left, add it to the right
-t = .9
t = .9
Please i need help with this please
Answer:
Your answer would be 9.
Step-by-step explanation:
You always do parenthesis first, 9-6 is 3, then you would do division 3÷3 is 1 then you multiply 4×2 and that would be 8, finally you would at the 8 and the 1 and that would give you 9 as your answer. Hope this helps

Anya found the slope of the line that passes through the points (–7, 4) and (2, –3). Her work is shown below.
Let (x2, y2) be (–7, 4) and (x1, y1) be (2, –3).
m = m equals StartFraction x 2 minus x 1 over y 2 minus y 1.
= Equals StartFraction negative 7 minus 2 Over 4 minus negative 3.
= Negative StartFraction 9 Over 7 EndFraction.
The slope is Negative StartFraction 9 Over 7 EndFraction..
What error did she make?
She simplified the denominator incorrectly. The denominator simplifies to –7.
She labeled the points incorrectly. The point (–7, 4) should be (x1, y1).
She used an incorrect formula. The formula should be the change in y-values with respect to the change in the x-values.
She used an incorrect formula. The formula should be the sum of the x-values with respect to the sum of the y-values.

Find an order pair (x,y) that is solution to the equation 3x-y=8
Answer:
(2.67,-8)
Step-by-step explanation:
You first make x 0 so it is -3x0 to cancel that out to find y. You then see that you get -y=8 so you make y positive by moving the negative to the other side to get y = -8. Then, you do the same type of process for x and get 2.67. I could be wrong but wanted help as much as I could!
Marlene purchased 20 stamps at the post office for $8.40. What is the cost of one stamp?
Answer:
they were .42¢ a piece I think this is right
The cost of one stamp will be $0.42.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Marlene purchased 20 stamps at the post office for $8.40.
Now,
Since, The cost of 20 stamps = $8.40
Hence, The cost of 1 stamp = $8.40 / 20
= $0.42
Thus, The cost of 1 stamp = $0.42
