What you do is multiply each number by 35. You get 35 by multiplying the denominators, 7 and 5. You then multiply the numerators and 51 by 35. Once you multiply the numerators you divide that answer by the denominator. Just remember, you multiply all of the numbers by 35 in this equation and ONLY divide the the answer by the denominator if it’s in a fraction.
When you convert them all..
10x+7=51
Now you can isolate the variable.
Subtract both sides by 7 so then it looks like..
10x = 24
Divide both sides by 10
Answer: x = 2 4/10; simplified to 2 2/5
Answer:
103.58
Step-by-step explanation:
Find the total area of the shape
L*W=A
8*13=104m
Find the area of the triangle, since the top of the shape is 13m then the bottom is also 13m.
4+4=8
13-8=5
So the base of the triangle cutout is 5m
Now find the area of the triangle. The formula for this is:
A=1/2 * base/height
A=1/2 * 5/6
A of triangle= 5/12m
104 - 5/12 =103.58m
The area of the shape is 12 square units
<h3>Area of a trapezium</h3>
The given shape is a trapezium and the formula for calculating the area of a trapezium is expressed as:
A = 0.5(a+b)h
Given the following parameters
a = 2
b = 10
h = 2
Substituting the given parameters
A = 0.5(2+10)*2
A = 0.2(12) * 2
A = 12 square units
Hence the area of the shape is 12 square units
