Answer:

-1 1/5

Step-by-step explanation:

Change the whole number 4 to an improper fraction

-4 4/5 ÷ 4/1 = -4 4/5 ÷ 4/1

Reciprocal the 4/1 will become 1/4 then go to multiplication

-4 4/5 ÷ 4/1 = -4 4/5 × 1/4

Change to improper fraction the -4 4/5

-4 4/5 ÷ 4/1 = -24/5 × 1/4

Then simply multiply the two numerators and the two denominators

-4 4/5 ÷ 4/1 = -24/20

Finally, Simplify it to get the answer

-4 4/5 ÷ 4/1 = -1 1/5

Please I need help with this question. No 22. Is very important. Thank you.

Answer:

C. $132m^3$

Step-by-step explanation:

Height = 4

Length = 6

Breadth = 7

Note : We were asked to find volume of the cuboid

Since, it has a base in the shape of a right angle triangle , we need to find the Area of the trapezium before calculating the total volume.

Step 1

Find the area of the trapezium

Area of a trapezium = $\frac{1}{2} (a+b)h$

$\frac{1}{2} (4+7)*4$

$\frac{1}{2} (11)4\\$

$\frac{1}{2} *44\\= 22$

Step 2

Calculate the volume of the cuboid

Volume of a cuboid =length× breadth × height

In this case , the volume will be our length × Area of a trapezium

V= 6 × 22

V = $132m^3$

What is the value of x in the equation 5(2x - 7) = 15x -10

ASHA 777 [7]

10x - 35 = 15x - 10
-35 = 5x -10
-25 = 5x
-5 = x
The value of x is -5.

Answer:

Step-by-step explanation:

10/7 = 1.4285

9/y = 1.4285

Multiply both sides by y.

9 = 1.4285y

Divide both sides by y.

6.3 = y

Help. show work please

olga2289 [7]

This would be an increase. You would have one fraction with 46 over 24 and next to it you would have X over 100. Multiply 46 times 100 and then divide that number by 24. This would be an increase of approximately 191.6
