Answer:

Each triangle weighs 3 grams.

Step-by-step explanation:

On the left side, there are 6 squares (12 grams) 3 circles (9 more grams), and 2 triangles (2x grams).

On the right side, there are 3 squares (6 grams) 2 circles (6 grams), and 5 triangles (5x grams).

This makes the equation 21 + 2x = 12 + 5x.

Let's find x.

21 + 2x = 12 + 5x

Subtract 5x from both sides.

21 - 3x = 12

subtract 21 from both sides.

-3x = -9

Divide by -3.

x = 3.

Each triangle weighs 3 grams. Let's prove this.

21 + 2x = 12 + 5x

21 + 2(3) = 12 + 5(3)

21 + 6 = 12 + 15

27 = 27

What is 1/4 divided by 1/2, and create and solve a real-world word problem that uses the above division expression.
Gnoma [55]

Answer:

1/4 divided by 1/2 equals 1/2

Real-world problem:

A constructor official knows that he needs 1/2 sack of cement to produce 10 blocks of concrete for a wall. The official only has 1/4 of the sack left and want to know how many blocks he can produce with this material.

Step-by-step explanation:

Since you know that 1/2 of the sack is needed to make 10 blocks, you can use this information to find the number of blocks that 1/4 of a sack can make. The question you want to answer is:  

if \frac{1}{2} of a sack produces 10 blocks, how may blocks \frac{1}{4} of a sack can produce?

Using the Rule of Three you can solve

\frac{\frac{1}{4} }{\frac{1}{2}} =\frac{2}{4}=\frac{1}{2}

Now you know that 1/4 of a sack can produce 1/2 the number of blocks that 1/2 of the sack can produces, this means that you can produce 5 blocks of concrete.

PLLLLZ HELLLLLLLLLLLPPPPPPP... i struggle so harddd...
Kazeer [188]
The answer is 6 schools.

In a box and whisker plot, every piece of whisker or box represents 25% of the whole number of schools.

The schools participated 1 year or less are represented by the left part of the whisker. Which stands for 25%.

To make an equation we need to set 100% = 24 and solve for 25% :
\frac{25}{100}  =  \frac{x}{24}
Set the denominators equal:
\frac{150}{600}  =  \frac{25x}{600}
Remove the denominators and solve:
150 = 25x  \\  \\ x = 6
