Mary made $216 for 12 hours of work. At the same rate, how many hours would she have to work to make $162?

Answer:

A=2.5

B=2

Step-by-step explanation:

A parallelogram has to have the opposite sides equal each other. In this case side LM and side ON have to be equal.

We can compare the two sides using algebra.

4b+7=8b-1

Using simple methods, we can isolate b on a single side.

1+7=8b-4b

8=4b

b=2

From this we learn b is 2. To find out the value of A on side MN and LO, we will plug in the value for b at all instances of B in this equation.

2a = 2b+1

2a = 2(2)+1

2a=4+1

2a=5

a=2.5

Answer: Minnie is 9 years old

Step-by-step explanation:

Eileen = e = 21

Minnie = m

E = 3m - 6

3m - 6 = 21

3m = 27

m = 9

Step-by-step explanation:

Answer:

It’s 8.8 so just leave it in that order

Step-by-step explanation:

Answer:8.8

Step-by-step explanation:

Given :

A parallelogram has sides 8 ft and 14 ft the height corresponding to the 14 ft base is 4 ft.

To Find :

The height corresponding to the 8 ft base.

Solution :

Since, both parallelogram are similar. So, ratio of the sides of parallelogram is similar in both the cases.

[tex]\dfrac{h_1}{h_2}=\dfrac{b_1}{b_2}\\\\\dfrac{8}{14}=\dfrac{h_1}{4}\\\\h_1 = \dfrac{8\times 4}{14}\\\\h_1 = 2.285 \ ft[/tex]

Therefore, the height corresponding to the 8 ft base parallelogram is 2.285 ft.

Answer:

1. The sum of two times a number (x) and -2 is at least 8 is first

2. Seven subtracted from 4 times a number (x) is more than 13 is second

3. Four added to 3 times a number (x) is less than 19 is third

4. Two less than 3/2 of a number (x) is no more than 5 1/2 is last

LOVE YOUR PFP!!!

Step-by-step explanation:

Answer:

1. Two less than 3/2 of a number (x) is no more than 5 1/2 is last

2. Seven subtracted from 4 times a number (x) is more than 13 is second

3. Four added to 3 times a number (x) is less than 19 is third

4.The sum of two times a number (x) and -2 is at least 8 is first

Los valores de y son 3/5 y -1

Los valores de x son = -12/5 y -4

Explicación paso a paso:

Dadas las eqautions;

x + 3 = y ...... 1

x ^ 2- 16y ^ 2 = 0 ..... 2

Sustituya la ecuación 1 en 2 que tendremos;

x ^ 2- 16y ^ 2 = 0

x² - 16 (x + 3) ² = 0

x²-16 (x² + 6x + 9) = 0

x²-16x²-96x-144 = 0

-15x²-96x-144 = 0

15x² + 96x + 144 = 0

5x² + 32x + 48 = 0

Al factorizar tendremos;

5x + 12 = 0 yx + 4 = 0

x = -12/5 y -4

Obtenga los valores de y;

recuerda que y = x + 3

Si x = -12/5

y = -12/5 + 3

y = 3/5

Si x = -4

y = -4 + 3

y = -1

Por tanto, los valores de y son 3/5 y -1

Answer:

Khalid’s rate is ___140_ miles per hour. Jesse’s rate is _150___ miles per hour. So, _Jesse’s___ train traveled at a faster speed.

Step-by-step explanation:

The general equation of a straight line is

y = mx + b

for y = 150x

We have the slope as 150

This is 150 miles/hour

This relates to Jesse’s train speed

for Khalid, we have his own speed obtainable from the graph

The speed is simply the slope of the graph

We proceed to select two points from the graph and find the slope

The points are; ((1,140) and (4,560)

Mathematically, the slope will be;

m = (y2-y1)/(x2-x1)

m = (560-140)/(4-1) = 420/3 = 140 miles per hour

Answer:

9x² + 16y² - 24xy

Step-by-step explanation:

(3x - 4y)²

⇒ (3x)² + (4y)² - 2 (3x) (4y)                                            {(a - b)² = a² + b² - 2ab}

⇒ 3²x² + 4²y² - 2 (12xy)
