Answer:

w = 1

Step-by-step explanation:

3w - 6+2w =-2 + w

5w -6 = -2 +w

5w -w = -2 +6

4w = 4

w = 4/4

w = 1

Subtract, 8 3/8 - 10 1/6

IRISSAK [1]

$8\frac{3}{8} = \frac{67}{6} \\ 10\frac{1}{6} = \frac{61}{6}$

$8\frac{3}{8} - 10\frac{1}{6}$

$convert$ them to: $\frac{67}{8} - \frac{61}{6}$

$\frac{67}{8} - \frac{61}{6} = \frac{-43}{24}$

Your $answer$ : $-1\frac{19}{24}$

Good luck on your assignment & enjoy your day

Alice needs 3/7 kilograms of flour for making a cake. How many of flour does she needs for making 42 cakes?

Oduvanchick [21]

Hey there!

3/7 is needed for 1 cake

If she needs to make 42 cakes, then multiply the amount for 1 by 42

42 × 3/7 = 126/7 = 18

She needs 18 kilograms of flour to make 42 cakes

Hope this helps :)

Which expression can be used to find the surface area of the following square pyramid

mariarad [96]

Answer:

a. 36+15+15+15+15

Step-by-step explanation:

The base of the pyramid is a square. We know that all sides of a square are equal so if we multiply the two sides of the base square(6*6) we get 36.

The area of a triangle can be found with the formula (b*h)/2. If we input the given values of 5 and 6 into our equation, then (5*6)/2 is 15 and since there are 4 triangles in the square pyramid, you multiply 15 by 4 (or add 15+15+15+15), and add the 36 from the base square.

Hope this helps :)

The diagram shows a scale drawing of a playground the scale of the drawing is 1:500 work out the perimeter of the real playgroun

liraira [26]

Answer:

Check Explanation

Step-by-step explanation:

The complete question plus diagram is presented in the attached image to this solution.

From the attached image, the dimensions of the playground drawn will be a bit variable now as zooming and some editing might have tampered with the original intended dimensions to be measured.

But still, let us assume that on measuring the rectangular playground shown, we obtain approximately that the length is 4.5 cm and the breadth is 2 cm.

The scale to convert to real life is 1;500 indicating that

1 cm on the drawing = 500 cm lenght units of the real playground.

So,

4.5 cm on the drawing = 4.5 × 500 = 2250 cm of the playground

2 cm on the drawing = 2 × 500 = 1000 cm of the playground.

Hence, the real life dimensions of the playground is 2250 cm by 1000 cm.

In meters, that is 2.25 m by 1 m

The perimeter of a rectangular figure is given as

Perimeter = 2(Length + Breadth)

= 2(2.25 + 1)

= 6.5 m

Hope this Helps!!!
