Step-by-step explanation:

Answer:

Kayla and Maddy will be in the same level in 4 days.

Step-by-step explanation:

Kayla: y = 6x + 12

Maddy: y = 2x  + 28

6x + 12 = 2x + 28

Subtract 2x from both sides;

4x + 12 = 28

Subtract 12 from both sides;

4x = 16

Divide both sides by 4;

x = 4

Answer:

Step-by-step explanation:

y = 6x + 12

y = 2x + 28

or

l = 6d + 12

l = 2d + 28

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.

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)

Answer:

rate of change = 1.75 over 1 or just 1.75

Step-by-step explanation:

this represents the cost of each cantaloupe. This basically means that each cantaloupe is $1.75.

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).

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

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.

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:

20-15=5

35-30=5

Answer: y = -4x + 5

Step-by-step explanation:

To write the equation in slope intercept form, we need to find the slope and the y intercept.

The y intercept is when the x coordinate is  zero, and looking at the line we can say the y-intercept is 5 because when x is 0 y is 5

y intercept: (0,5)

Now find another point on the line to find the slope  of the line .  

(-2,13)  

The slope is the difference between the y coordinates divided by the difference in the x coordinates.

(0,5)   and (-2,13)

y coordinates:  5 - 13 = -8

x coordinates:  0 - (-2) = 2

  Slope:  -8/2 = -4
