Following PEMDAS: Do the division first followed by the subtraction.
[tex]33-8\div4=33-2=31[/tex]
Answer:
31
Step-by-step explanation:
You would have to do 8 divided by 4 then you would have to subtract that answer by 33.So 8 divide by for is 2 so 33-2= 31.

Step-by-step explanation:
In the expression 4x+ 2y -3x +5y^2 +3z- 4z^2
O 2y and 5y2
0 4x and -3x
0 -3x and 32
3z and 4z^2
Answer:
4x and -3xStep-by-step explanation:
We can simplify only like terms in an algebraic expression.
Terms are "like terms" only if they consist the same letters with the same exponent.
The only difference between like terms is their coefficients are different.
So:
2y and 2y² are not like terms (different exponents at y)
4x and -3x are like terms (the same letter, the same exponent)
-3x and 32 aren't like terms (no x with 32 means different exponents)
or if you meant:
-3x and 3z aren't like terms (different letters)
3z and 4z² aren't like terms (different exponents at z)
is 6.3434 rational or irrational
Answer:
it is a rational number

Clarisse decided to do the 52 a week Money Saving Challenge. In the first week of January, she saved Php 5.00. In the second week of January, she saved Php 10.00. In the third week of January, she saved Php 15.00. If the increment was the same for the whole year,
-How much did she save on the 52nd week?
-How much was her total savings after 52 weeks?
Answer:
1378
Step-by-step explanation:
once you’ve decided on your New Year’s resolutions, the best way to make sure you actually follow through is by developing a plan for how to accomplish your new goals.
For anyone with “saving money” at the top of their list in 2020, the 52-week money challenge is a simple and effective way to stay on track. And at the end of the year, you’ll have $1,378 extra dollars to bulk up your emergency savings or put towards next year’s vacation.
Take some time now to determine what, exactly, you want to save for so you’ll be more motivated to stay the course throughout the year. Once your savings goals are set, jump in and start saving with the 52-week money challenge.
What is the 52-week money challenge?
Using the 52-week money challenge, you should deposit an increasing amount of money each week for one year.
Match each week’s savings amount with the number of the week in your challenge. In other words, you’ll save $1 the first week, $2 the second week, $3 the third week, and so on until you put away $52 in week 52. You can also get creative with the amount you save each week if you’d like to save more over the year or you don’t have enough extra cash available for the regular challenge.
If you stick to this challenge throughout the entire year, you’ll save a total of $1,378.

After distributing the terms (2x + 3) (4x – 5), you get a new expression of the form
ax+ bx + c
What is the value of a?
What is the value of b?
What is the value of c?
Answer:
Value of a = 8
Value of b = 2
Value of c = - 10
Step-by-step explanation:
[tex](2x + 3)(4x - 5)[/tex]
[tex] = > 2x(4x - 5) + 3(4x - 5)[/tex]
[tex] = > 8 {x}^{2} - 10x + 12x - 15[/tex]

4(5a-2b)-2(4a-5b)
Expand the brackets and simplify the question
Answer:
12a+2b
Step-by-step explanation:
1. Expand by distributing terms.
20a-8b-2(4a-5b)20a−8b−2(4a−5b)
2. Expand by distributing terms.
20a-8b-(8a-10b)20a−8b−(8a−10b)
3. Remove parentheses.
20a-8b-8a+10b20a−8b−8a+10b
4.Collect like terms.
(20a-8a)+(-8b+10b)(20a−8a)+(−8b+10b)
5. Simplify.
12a+2b12a+2b
6.Answer
12a+2b
Solve for x.
17b + bx = 34x – a
Answer:
17b + bx + a over 34 =x
Answer:
Shoot I don't know but this is as far as I got until I got confused.
Step-by-step explanation:
17b + bx = 24x - a
-17b = - 17b
-24x = -24x
------------------------------
-24x + bx = -17b - a
-24x + bx/b = -17b/b - a/b
-24x + x = -17b - a/b
-23x = -17b - a/b
-23x/-23 = -17b/-23 - a/b/-23
x =
