225 grams of flour are needed to make 9 cakes.Marian wants to make 20 of these cakes.
She has 475 grams of flour.
Does Marian have enough flour to make 20 cakes?

Answers

Answer 1

Answer: So basically, 9 cakes need 225 grams of flour
Therefore 1 cake needs: $(225)/(9)$ = 25 grams of flour

Moreover, 20 cakes need: 20 × 25 = 500 grams of flour

500 g > 475 g

Marian does not have enough flour to make 20 cakes

x = 1

Step-by-step explanation:

$3(4x - 3) = - 4 + 7$

Expand:

$3(4x - 3) = 12x - 9 \n 12x - 9 = - 4 + 7$

Simplify:Addvalues

$12x - 9 = 3$

Collect like terms and simplify

$12x = 3 + 9 \n 12x = 12$

Divide both sides of the equation by12

$(12x)/(12) = (12)/(12)$

Simplify

$x = 1$

Answer:

x = 1

Step-by-step explanation:

Original Equation:

3(4x - 3) = -4 + 7

Use the distributive property.

3 x 4x = 12x

3 x -3 = -9

Equation:

12x - 9 = -4 + 7

Add 4 to both sides.

12x - 5 = 7

Add 5 to both sides.

12x = 12

Divide both sides by 12

x = 1
