Answer:
D. -1.2(3x-40)
Step-by-step explanation:
Multiply -1.2 x 3x and -1.2 x -40.
-1.2 x 3x= -3.6x
-1.2 x -40= 48 (two negatives cancel each other out, so it will be +48)
= -3.6 +48.
You can also automatically eliminate B. and C. because multiplying the -4 within the perenthesis would not give you 48.
A. says (3x + 40), which would give us a negative 48.
Well first you would substitute or plug in the values.
2(3+4+4)
Now we will follow the order of operations, or PEMDAS
2(11)=22
Your answer is 22
Answer: Osvoldo did not meet his goal.
Step-by-step explanation:
If he ate 220 grams of carbohydrates today and 55 grams were from whole grains, it means that the percentage of the carbohydrates he ate today that came from whole grains is
55/220 × 100 = 25%
Since he has a goal of getting at least 30% percent of his grams of carbohydrates each day from whole grains, then he did not meet his goal because 25% is lesser than 30% and he needs 30% or more
5x (-7)y=4
y=-4/35
5x=4
x=4/5
(x, y) = (4/5, 4/35)
