ycow [4]

Answer:

B)x=6

Step-by-step explanation:

Given the equation \frac{1}{2}x+\frac{1}{4}=\frac{1}{3}x+\frac{5}{4}

-We first group the like terms on the same side of the equal side;

\frac{1}{2}x-\frac{1}{3}x=\frac{5}{4}-\frac{1}{4}\\\\\\\\\frac{1}{6}x=1

#Multiply both sides by 6 to remove denominator;

6\times \frac{1}{6}x=1\times6\\\\x=6

Hence, x=6

The line graph below shows the number of chocolate bars and ice lollies sold at a small shop over a year
AnnyKZ [126]

Answer:

<em>The sales of ice lollies increased by 76 units between February and August</em>

Step-by-step explanation:

<u>Graph Reading</u>

Line graphs are visual ways of representing two or more data sets and their interrelation.

Graphs are pictures that show how one variable changes in relation to another.

Learning to properly read graphs is a matter of interpreting which pieces of information are useful.

The graph (in the red drawing) shows how sales of ice lollies changed in time. By February, the sales were about 4 units and by August sales were up to 80 units.

This means an increase of 80 - 4 = 76 units.

The sales of ice lollies increased by 76 units between February and August

Please solve for me it's urgent. A rectangle has 10 and 6cm each. find the area of a square with the same perimeter as that of t
elena55 [62]

Answer:

64 cm²

Step-by-step explanation:

Firstly,let us lay down the clues;

So, we have been given the Length and Width of the rectangle.

Rectangle;

<em>Length</em><em>=</em><em> </em><em>10</em><em> </em><em>cm</em>

<em>Width</em><em>=</em><em>6</em><em> </em><em>cm</em>

We know that

Perimeter= 2L + 2W

Perimeter= 10+10+6+6

Perimeter =32 cm

In the questionnaire, it is mentioned that a square has the same perimeter as the rectangle. That means, the perimeter of the square is similar to the one of the rectangle which is 32 cm.

So,

Perimeter of square =32 cm

Length of one side of the square =32÷4

=8 cm

Area= L × W

Area= 8 cm× 8 cm

Area= 64 cm²

Hope it helps.
