$5m-7=6m+11$

We want to isolate "m" on one side of the equation and have a number on the other side. Let's start by subtracting both sides by 5m

$5m-7-5m=6m+11-5m$

$-7=m+11$

Now, let's subtract both sides by 11

$-7-11=m+11-11$

$-18=m$

We now have the value of m.

The next thing I'm going to do is a bit tedious, but you typically want to have the variable on the left side of the equation in the field of math. It's a good habit to develop now.

$m=-18$

Thus, the answer is choice 3, -18. Let me know if you need any clarifications, thanks!

Find lcm of 14 and 28 in vertical method

guapka [62]

Answer:

Step-by-step explanation:

We will keep dividing by prime numbers until both are one (we will only consider whole divisions)

```

14 28 | 2

7 14 | 2

7 7 | 7

1 1

Now we <em>m</em><em>u</em><em>l</em><em>t</em><em>i</em><em>p</em><em>l</em><em>y</em> the left collumn, to get the LCM

2 * 2 * 7 = 28

And this was the vertical method, ok?

The square of a negative number is twenty-eight more than three times the negative number. Find the number.

MAXImum [283]

The number is x

it is negative
the square is 28 more than 3 times itself
x²=28+3x
minus (28+3x)
x²-3x-28=0
factor
(x-7)(x+4)=0
set to zero

x-7=0
x=7
this is not the answer because we were told the number was negative

x+4=0
x=-4
correct

the number is -4
test
(-4)²=28+3(-4)
16=28-12
16=16
check

the number is -4

What is the slope of a Line that goes through (1,0) and (5,3)<br><br> 3/4<br> 4/3<br> 3<br> 4

andre [41]

To find the slope(m), you use the slope formula:

$m=\frac{y_2-y_1}{x_2-x_1}$ And plug in the two points

(x₁ , y₁) = (1, 0)

(x₂ , y₂) = (5, 3)

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{3-0}{5-1}$

$m=\frac{3}{4}$

Mrs. Williams combined 3 ½ cups of peat moss, 5 ¼ cups of compost , and 6 ¾ cups of fertilizer to make plant food for her roses.

Stolb23 [73]

Answer:

3 7/8 cups plants food

Step-by-step explanation:

peat moss = 3 ½ cups

compost = 5 ¼ cups

fertilizer = 6 ¾ cups

Total mixture = peat moss + compost + fertilizer

= 3 ½ cups + 5 ¼ cups + 6 ¾ cups

= 7/2 + 21/4 + 27/4

= 14+21+27/4

= 62/4

Total mixture = 62/4 cups

She evenly distributed the plant food among 4 rose bushes

Each rose bush uses = Total mixture / number of rose bushes

= 62/4 ÷ 4

= 62/4 × 1/4

= 62/16

= 3 14/16

= 3 7/8 cups plants food

Each rose bush uses = 3 7/8 cups of plants food
