x-(2x+3)
how to solve and why you change the sign for the +3?
Answer:
-x - 3
Step-by-step explanation:
x-(2x + 3)
=> x-1(2x + 3)
=> x - 2x - 3
=> -x - 3
Therefore, this is the solution. Hoped this helped.

Answer:
Step-by-step explanation:
x-(2x+3)
Notice that we can't further simplify the things in the bracket so we should multiply by -1
Technically this is like:
x - 1(2x+3)
-1 times 2x = -2x , -1 times 3 is -3
= x - 2x - 3
= -x - 3
5. Randall wants to buy a pizza. He can
select from 4 different sizes (s,m,Ixl), three
types of crust (pan, thin, hand toss), and
two toppines (cheese or pepperoni). How
many different outcomes of pizza can
Randall order?
Answer: 18 outcomes
Step-by-step explanation:
For the small:
pan+cheese
or
pan+pepperoni
or
thin + cheese
or
thin + pepporoni
or
hand + cheese
or
hand + pepperoni
which is 6 outcomes
then 6x3(because of the sizes) is 18.

If a - 5b - 3 = 8, then the straight line ax + by + c = 0 must pass through the point
I) (1, 5)
II) (1, -5)
III) (5, -1)
IV) (-1, 5)
Please show your work...No spam.. Thank you.
Answer:
III) (5, -1)Step-by-step explanation:
Given relationship between the constants of the line ax + by +c = 0:
a - 5b - 3c = 8We can try options, the obvious one is:
a = 0, b = - 1, c = - 1In this case the line becomes:
0x - y - 1 = 0y = - 1This gives us the point (5, - 1), the option III

[tex]0.399 + w = 0.4[/tex]
Answer:
[tex] \sf \: w = 0.001[/tex]
Step-by-step explanation:
Now we have to,
→ find the required value of w.
The equation is,
→ 0.399 + w = 0.4
Then the value of w will be,
→ 0.399 + w = 0.4
→ w = 0.4 - 0.399
→ [ w = 0.001 ]
Hence, the answer is 0.001.

The graph of f(x) = (0.5)x is replaced by the graph of g(x) = (0.5)x − k. If g(x) is obtained by shifting f(x) down by 7 units, then what is the value of k?
k equals one seventh
k equals negative one seventh
k = 7
k = −7
Answer:
k = 7
Step-by-step explanation:
Vertical shift down by 7units, f(x) - 7
g(x) = (0.5)x - 7
g(x) = (0.5)x - k
Comparing both equations, k = 7
Answer:
k = 7
Step-by-step explanation:
it would be 7 and not -7 because there is already a minus symbol which shows that k is being moved downwards 7 UNITS.

A bag of 12 oranges weighs 4 1/2 pounds, if the oranges are about the same size, how many pounds does each orange weigh
25 POINTS
0.385
Take the weight of the bag and divide it by the number of oranges in the bag (12) which is:
4.5 / 12 = 0.385
Each orange weighs 0.385 pounds.
Dom mowed 2/5 of his lawn. Maddy mowed 1/4 of it. who mowed most. how much more needs to be mowed
Answer:
Dom mowed the most and 7/20 is how much is left
Step-by-step explanation:
To compare the answer of which is larger you need a like denominator. Maddy: 5/20
Dom: 8/20
Now what is left for them to do is 7/20.
what is 18/15 in lowest terms
Answer:
Find the GCD (or HCF) of numerator and denominator. GCD of 18 and 15 is 3.
18 ÷ 315 ÷ 3.
Reduced fraction: 65. Therefore, 18/15 simplified to lowest terms is 6/5.

Osmosis is when:
A) Water molecules move from a low concentration, to a low concentration, with the assistance of travel proteins.
B) Salt molecules move from a high concentration, to a low concentration, with the assistance of travel proteins.
C) Water molecules move from a high concentration, to a low concentration, with the assistance of travel proteins.
D) Salt molecules move from a low concentration, to a low concentration, with the assistance of travel proteins.
Answer:
C
Step-by-step explanation:
Osmosis: In osmosis, water always moves from an area of higher water concentration to one of lower concentration. In the diagram shown, the solute cannot pass through the selectively permeable membrane, but the water can. Water has a concentration gradient in this system.
HOPE THAT HELPS YOU PLS MARK ME BRINILYS
Answer:
A hey the answer because osmosis means small when molecules when molecules from a hydrophenation with the help of travel proteins most are low concentration

write the equation of the line that is parallel to Y=2/3 X -7 and passes through the point (-3,1)
Answer:
y=2/3x+3
Step-by-step explanation:
parallel means it stays the same so its still 2/3
now use the equation y=mx+b
plug in the slope which is 2/3
so we get y=2/3x+b
then plug in the 2 points
1= 2/3(−3)+b
1=-6/3+b
1=-2+b
add 2 to 1 and -2
3=b
so we get y=2/3x+3

4. Corresponding sides of congruent triangles are congruent
Step-by-step explanation:
I marked this in the attached image. ∠B ≅∠E, ∠ACE ≅ ∠DCE, and the side between them BC ≅ EC, so the the triangles ΔACB and ΔDCE are congruent by ASA.
If the triangles are congruent, then all corresponding angles and sides are also congruent.
