Julius has a garden that has dimensions of 12 ft by 20 ft. Julius needs more room to plant some peppers, and determines the gard

alukav5142 [94]

Answer:

C. 3.4 feet

Step-by-step explanation:

Let, the amount of increase be 'x' feet.

As, the length and width of the garden are 20 ft and 12 ft respectively.

It is given that the area of the new garden is 360 ft²

Since, the length and width are increased by 'x'.

The new length and width are (x+20) ft and (x+12) ft respectively.

So, we get,

New area, $A_{G}$ = length × breadth = (x+20) × (x+12)

i.e. 360 = $x^{2}+32x+240$

i.e. $x^{2}+32x-120=0$

i.e. (x+35.4)(x-3.4)=0

i.e. x = -35.4 and x= 3.4

Since, the value of x cannot be negative.

Thus, x = 3.4 feet.

Please do them step by step;

ELEN [110]

For the first one c-9=(2)(4)+6
You are gonna multiply 2 and 4 first, 2*4=8. Now you have c-9=8+6. 8+6=14. So now the equation is c-9=14. Now we are going to add 9 to both sides. So c=23
For the second equation 10+y=90. We are going to subtract 10 from both sides. So, y=80.
Third, add 4 to both sides. a=10.
Fourth, subtract 8 from both sides. d=-9
Fifth, 5+2(3+4)=-x.
First we are going to add 3 and 4. 3+4=7. 5+2(7)=-x. Next we are going to multiply 2 and 7. 2*7=14. 5+14=-x. 5+14=19. So our equation is 19=-x. Next we are going to multiply both sides by -1. Making our final equation x=-19.
c=23
y=80
a=10
d=-9
x=-19
I hope that helps, if you need any further explanation just ask.

Use a inequality symbol to compare -3x+7 -10-2

abruzzese [7]

Hey there,

Let's remember that a (inequality symbol) is things like (<), (>), (≤),(≥), (≠).

So, I believe that (-3x+7) and (-10-2) are separate. So we will find that out :)

Let's first do (-3x+7). As simplifying this expression here, we take that "x" of for a while and just stick to (-3+7).

-3
+ 7
______
4

Let's bring that "x" back, and the answer would be 4x for a while.

So far, 4x is the answer.
_____________________________________________________________

Now, Let's work on the other side.

We are talking about (-10-2)

-10
- 2
_______
 -12

So, by solving the answer to (-10-2), we got -12.

So, let's determine what is greater . . . . .

$What \ is \ greater?$

-12 or 4.

-12 is on the negative side, and the number 4 is positive. This would conclude that 4 is great than -12.

Your correct answer would look like . . .

(-3x+7) > (-10-2)

I really hope this helps you alot.

Mitch used 1 4 pounds of beef to make 3 4 liters of beef strogonoff. If Mitch's recipe is for 1 liter of beef strogonoff, how ma

iren [92.7K]

option B) 3 pounds of beef is needed to make 6 times the recipe.

Step-by-step explanation:

step 1 :

Mitch used 14 pounds of beef = 34 liters of beef strogonoff

'x' pounds of beef = 1 liter of beef strogonoff

step 2 :

Rate = No. of pounds / No. of liters

(14 pounds / 34 liters) = (x pounds / 1 liter)

x = 14/34

x = 0.412

1 liter of beef strogonoff = 0.412 pounds of beef

step 3 :

To make 6 times the recipe = 6 $\times$ 0.412

= 2.5 pounds of beef ( approximately 3 pounds)
