The answer is C
x= months
y=$
Constant of proportionality (C)=y/x
x=1, y=3.5
3.5/1=3.5
x=2, y=7
7/2=3.5
x=3, y=10.5
10.5/3=3.5
x=4, y=14
14/3=3.5
x=5, y=17.5
17.5/5=3.5
C=3.5

In Lixue's garden, the green pepper plants grew 5 inches in 3/4 month. At this rate, how many feet can they grow in one month? (

steposvetlana [31]

Answer:

$\frac{20}{27}$ feet

Step-by-step explanation:

We can simply set up a ratio to solve this problem.

Since plant grew 5/9 foot in 3/4 month, how many feet (let it be x) can it grow in 1 month??

We can set up the ratio shown below, cross multiply and solve for x:

$\frac{\frac{5}{9}}{\frac{3}{4}}=\frac{x}{1}\\\frac{5}{9}*1=\frac{3}{4}*x\\\frac{5}{9}=\frac{3}{4}x\\x=\frac{\frac{5}{9}}{\frac{3}{4}}\\x=\frac{5}{9}*\frac{4}{3}\\x=\frac{20}{27}$

Hence, we can say the pepper plant will grow 20/27 feet in 1 month.

Which ordered pair (m, n) is a solution to the given system of linear equations?

LuckyWell [14K]

Answer:

Option (c) is correct.

The ordered pair (-4, -1) is a solution to the given system of linear equations.

Step-by-step explanation:

given : system of linear equations.

6m - 5n = 14

2m + 2n = - 10

We have to find the solution to the given system of linear equations.

Consider the given system of linear equations.

6m - 5n = 14 ......(1)

2m + 2n = - 10 .......(2)

We solve the given system using elimination method,

multiply equation (2) by 3 , we have,

(2) ⇒ 6m + 6n = - 30 ..............(3)

Subtract equation (1) and (3) we have,

6m + 6n - (6m - 5n) = - 30 -14

Simplify, we have,

6n + 5n = - 44

11n = - 44

n = - 4

Put n = -4 in (1) , we have,

6m - 5n = 14 ⇒ 6m - 5(-4) = 14 ⇒ 6m = 14 -20 ⇒ 6m = -6 ⇒ m = -1

Thus, the ordered pair (-4, -1) is a solution to the given system of linear equations.

Somebody answer !!!!!

Rainbow [258]

Answer:

Step-by-step explanation:

First we have to subtract 5 from both sides

$\sqrt{x-6} +5=12\\\\\sqrt{x-6}+5-5=12-5\\\\\sqrt{x-6}=7$

Now, square both sides

$(\sqrt{x-6})^{2}=7^{2}$

x - 6 = 49

Now, add 6 to both sides

x - 6 +6 = 49 + 6

x = 55
