The Order of Operations would tell you
1. substitute the value of the variable
2. evaluate multiplications
3. evaluate the sum
25*4 +40*4
100 +160
260
Personally, I would combine terms and rewrite it to be
.. (25 +40)x
.. 65x
.. 65*4
.. 65*2*2
.. 130*2
.. 260

The Order of Operations is the rule book for evaluating expressions. However, we know that multiplication and addition are associative and commutative, and that the distributive property applies.
If you are evaluating expressions in a computer program, there are methods for assuring minimum round-off and truncation errors that have little to do with any of the above, but everything to do with how numbers are represented in a computer and the way compilers work.
Answer:
Option (A)
Step-by-step explanation:
AE and RV are the two line segments intersecting at a point N.
Therefore, ∠ANR ≅ ∠ENV [Vertical angles are equal in measure]
(8x + 12)° = (5x + 57)°
8x - 5x = 57 - 12
3x = 45
x = 15
Since, m∠ENV = 5(15) + 57
= 75 + 57
= 132°
Therefore, Option (A) will be the answer.
Answer: one gallon per hour is equal to 2.13 ounces per minute. If you just multiply that by 100, you'll get 213. So approximately 213 oz./min.

Answer:
The ratio of flour to sugar is 2:1
Step-by-step explanation:
Let f = weight of a bag of flour
Let s = weight of a bag of sugar
3f+2s = 32
4f = 32
We have 2 equations and 2 unknowns, we can solve
4f=32
Divide by 4
4f/4 = 32/4
f = 8
Each bag of flour weights 8 pounds
Substitute this back into the first equation
3(8) +2s = 32
24+2s = 32
Subtract 24 from each side
24-24 +2s =32-24
2s = 8
Divide by 2
2s/2 = 8/2
s = 4 pounds
Flours weighs 8 pounds and sugar weights 4 pounds
We want the ratio of flour to sugar
Flour: sugar
8:4
We can divide each side by 4
8/4: 4/4
2:1
A.
Juan Increase 25/350 = .071 * 100 = 7 %
Rhia Increase 75/275 = .273 * 100 = 27 %
Max Decrease 40/400 = .1 * 100 = 10 %
b.
Juan sold more than $355 but his increase was less than 10% so he did not get a bonus.
Rhia had an increase more than 10% but she did not sell more than $355 so she did not get a bonus.
Max had a decrease so he did not get a bonus.
