Solve for x. 2(2-x) + 12x =44
Answer:
2(2-x)+12x=44
4-2x+12x=44
-4 -4
-2x +12x = 40
10x=40
/10 /10
x=4
Step-by-step explanation:
first you multiply the (2-x) by 2, you then subtract the 4 from both sides of the equation, you end up with -2x +12x = 40. Then subtract the 2x from the 12x and you end up with 10x. so now 10x=40. You then divide both sides by 10 and end up with x=10
sorry im not to good at explaining haha

A car is moving at a steady rate. The distance it travels is proportional to the amount of time, in hours, it has been driving. It has traveled a total of 168 miles in 3 hours. (a) What is the ratio of the distance to the number of hours? Express as a fraction and as a unit rate with appropriate units.
Step-by-step explanation:
let distance travelled be d miles and time be t hours.
d = kt where k is a constant, k ≠ 0
168 = 3k
k = 56
d/t = k
hence it's ratio is 56 : 1 and fraction is 168/3 = 56/1 and fraction with unit is 56miles/hour.

Rita is adding 3 + (negative 8) + 1. She rewrites the expression as 3 + (negative 1) + 8. What is Rita’s error? She used the commutative property, which cannot be used with negative numbers. In the new expression, –8 and 1 should both be negative. She used the associative property which should only be used with positive numbers.. She switched the negative signs for –8 and 1.
She used the associative property which should only be used with positive numbers (sorry if it isn't the answer you're looking for)

(1,4) and (3,7)
m =
PLEASE HELP I DONT UNDERSTAND THIS
Answer: 3/2
Step-by-step explanation:
To find slope you use the formula: m= y2-y1/x2-x1
So plugging stuff in it’s (7-4)/(3-1)
This comes out to be 3/2
Which means when graphing you go up 3 and right 2

Answer:
F, T, T, T, T, F
Step-by-step explanation:
PM and PN are "midlines" of the triangle JKL. As such, they are parallel to and half the length of the side of ΔJKL they don't intersect. The relationships of angles and transversals of parallel lines apply. LMPN is a parallelogram, so opposite sides are the same length.
a) JL is not 36, it it twice that. (F)
b) ML is the same length as PN, 36. (T)
c) MP is half of LK, so is 97/2 = 48.5. (T)
d) ∠JLK corresponds to ∠JMP, so is congruent. (T)
e) ∠PNK corresponds to ∠JLK, so is congruent. (T)
f) MP intersects PK at point P, so cannot be parallel. (F)

Greg earns a salary of $300 per week plus an additional
6% commission on his sales. If his weekly salary
increases by $50 and his commission increases to 7%
how much will Greg earn if his weekly sales are
$4,000?
Given :
Greg earns a salary of $300 per week plus an additional 6% commission on his sales.
To Find :
If his weekly salary increases by $50 and his commission increases to 7% how much will Greg earn if his weekly sales are $4,000.
Solution :
New weekly salary, S = $( 300 + 50 ) = $350 .
New commission on $4000 sales :
[tex]C=\dfrac{4000\times 7}{100}= \$280[/tex] .
Therefore, total earning T = S + C = $( 350 + 280 ) = $630 .
Hence, this is the required solution.
A recipe for 4 cups of trail mix calls for 2··3cup of raisins. Aniyah has 1 1··2cups of raisins. Does Aniyah have enough raisins to make 14 cups of the trail mix? If not, how many more cups of raisins does Aniyah need?
Answer:
Aniyah does not have enough for 14 cups, and needs 1 1/6 more.
Using the required arithmetic concept, we can conclude that Aniya needs 7/6 more cups.
Representing the problem thus:
4 cups of trail = 2/3 cups of raisins
14 cups of trails = x
Cross multiply
4x = (2/3) × 14
4x = 28/3
x = (28/3) ÷ 4
x = (28/3) × (1/4)
x = 7/3
Cups of raisins Aniya has = 1 1/2 = 3/2
Extra cups needed = 7/3 - 3/2 = 7/6 cups
Therefore, Aniya does not have enough, she needs 7/6 more cups.

Step-by-step explanation:
Lntegers 0, -2, -3, -4, -5, -6, -7, -8, and -10 to fill in a 3 x 3 magic square so that every row, column, and diagonal has the same sum. The sum must be -15.
The given numbers are 0, -2, -3, -4, -5, -6, -7, -8, and -10.
Sum of all the integers is -45.
There are 9 places in 3x3 magic square, so divide -45 by 9, we have -45/9=-5.
Put the number -5 at the center place in the magic square.
Now, take the integer having the largest magnitude, i.e -10.
There are two positions to place -10, one is diagonal positions and the other is non-diagonal positions and to make sum = -15, the other number with -5 and -10 must be 0 as shown in the figure (i) and (ii).
Now, the row and column having 0 must have -8 and -7 to make sum -15, which disregards the possibility of -10 at the diagonal place ( figure (i)). So, proceeds with the places in figure (ii), the possible places of -8 and -7 have been shown in figure (iii).
Now, as the sum of diagonals = -15, so place -3 and -2 at diagonal positions and also place the remaining numbers -4 and -6 to make the sum of numbers in columns and rows -15 as shown in figure (iv).
