7-0.3×&gt;4<br>solve for x​
Troyanec [42]

Answer:

x<10

Step-by-step explanation:

Add '-7' to each side of the equation.

7 + -7 + -0.3x = 4 + -7

Combine like terms: 7 + -7 = 0

0 + -0.3x = 4 + -7

-0.3x = 4 + -7

Combine like terms: 4 + -7 = -3

-0.3x = -3

Divide each side by '-0.3'.

x = 10

Simplifying

x = 10

I need help ASAP.... please help....
avanturin [10]

Answer:

(7x-1)(x-3)

Step-by-step explanation:

7x^2 - 22x + 3

The factors have to add to -22, but multiply to equal 3. But since the "a" value has a number on it, you have to use it too.

(7x +/- [n1]) ( x +/- [n2]) = 7x^2 - 22x + 3

Since the two numbers multiply to a positive value, they have to have the same sign. (7x-1) (x-3) works to produce the expression when it's foiled.

A cookie recipe requires 3 teaspoons of baking soda for 36 cookies. If the baker would like to make 480 cookies, how much baking
Vitek1552 [10]

Answer:

It would require 40 teaspoons

Step-by-step explanation:

Given that;

A cookie recipe requires 3 teaspoons of baking soda for 36 cookies

The amount of teaspoons of baking soda required per cookie is;

r = 3/36 teaspoons per cookie

So, for 480 cookies i would require;

N = r × 480 cookies

Substituting r, we have;

N = 3/36 teaspoons per cookie × 480 cookies

N = 40 teaspoons

It would require 40 teaspoons

What's the solution to<br> 1/5+1/3x&gt;1/2-1/4?
Serjik [45]

Answer:

x> 3/20

Step-by-step explanation:

Let's solve your inequality step-by-step.

1 /5  +  1 /3  x>  1 /2  −  1 /4

Step 1: Simplify both sides of the inequality.

1 /3 x+  1 /5  >  1 /4

Step 2: Subtract 1/5 from both sides.

1 /3 x+  1/ 5  −  1 /5  >  1 /4  −  1 /5  1 /3  x>  1 /20

Step 3: Multiply both sides by 3.

3*( 1 /3 x)>3*( 1 /20 ) x> 3 /20

Answer:

x>  3/ 20

Hope this helps!!
