Answer:

Step-by-step explanation:

Alright we are going to be simplifying

-4(x - 4) = 20 Divide sides by -4

x-4=-5

So,

x-4=-5 Add 4 to the sides

x-4+4=-5+4

-1

So therefore, your answer is x=-1

Hey!

In order to simplify this equation, we'll first have to multiply both sides of the equation by v. This will give us v on its own.

Original Equation :
$\frac{-3}{v} = -6$

New Equation {Added Multiply Both Sides by V} :
$\frac{-3}{v} v=-6v$

Solution {New Equation Solved} :
$-3 = -6v$

Now we'll switch sides to get v on the left side of the equation which is generally where we always want the variables to be located in these types of equations.

Old Equation :
$-3 = -6v$

New Equation {Switched} :
$-6v=-3$

Now we'll divide both sides by v to get v on its own.

Old Equation :
$-6v = -3$

New Equation {Added Divide Both Sides by V} :
$\frac{-6v}{v} = \frac{-3}{v}$

Solution {New Equation Solved} :
$v = \frac{1}{2}$

So, this means that in the equation $\frac{-3}{v} =-6$ , $v = \frac{1}{2}$ .

Hope this helps!

VERY URGENT.

Answer:

(1)Base Area= 81 square yards.

(2)

3 ft long and 16 ft wide

6 ft long and 8 ft wide
24 ft long and 2 ft wide

(3)Height=12 Units

Step-by-step explanation:

Question 1

Volume of the rectangular prism=2,592 cubic yards.

Height of the rectangular prism=32 yards

Volume of a rectangular prism =lbh (where lb is the Base Area)

Therefore:

lbh=2592

32lb=2592

lb=2592/32=81

Base Area= 81 square yards.

Question 2

Volume of the rectangular prism=432 cubic feet.

Height of the rectangular prism=9 feet

Volume of a rectangular prism =lbh (where lb is the Base Area)

Therefore:

lbh=432

9lb=432

lb=432/9=48

Base Area= 48 square yards.

Any dimension whose product is 48 is a possible choice.

They are:

3 ft long and 16 ft wide
6 ft long and 8 ft wide
24 ft long and 2 ft wide

Question 3

Volume of the rectangular prism=960 cubic units.

Base Area of the rectangular prism, lb=80 Square Units

Volume of a rectangular prism =lbh (where lb is the Base Area)

Therefore:

lbh=960

80h=960

h=960/80=12

Height= 12 units.

A recipe requires 1\4 of a cup of cranberries for 1 batch. How many beaches of scones can be made using 6 1/2 cups of cranberrie

TiliK225 [7]

Answer:

Step-by-step explanation:

1 batch is 1/4 cups of cranberries.

This means that we have to find the number of groups of 1/4 in 6 1/2 cups to find the number of batches.

(The decimal forms of these numbers are 6.5 and 0.25)

6.5/0.25=26

There are 26 batches

last minute forgot to do it please help and do all of them and I have one more I promise I’ll give you good ratings :D

1.) The error is that she attached the

variable with the flat fee (which is

constant) and put the daily rent as a

constant (which is variable).

The correct equation is:

365+125x=250+175x

2.) N=5

3.) k=-35.

Explanation: Solution:

17k-6=37k+4 . 17k-37k=4+6 .

-27k=10 . k=10\cdot(7-2) . k=-35 .

4.)

$y = - \frac{9}{16}$
