Answer:
<h2>5</h2>
Step-by-step explanation:
Given the following angles ∠BOC=x+3, ∠AOB=4x−7, and ∠AOC=21, the expression is true about the angles;
∠AOC = ∠BOC+∠AOB
Substituting the given values into the expression, we will have;
21 = x+3+4x-7
collect the like terms
21 = x+4x+3-7
21 = 5x-4
Add 4 to both sides
21+4 = 5x-4+4
25 = 5x
Divide both sides by 5
5x/5 = 25/5
<em>x = 5</em>
<em></em>
<em>Hence the value of x is 5</em>
Answer:
x+y/10-b
Step-by-step explanation:
Factor out the common term: 10
Divide both sides by 10
Subtract b from both sides
Answer:
Hey there!
16(4x^6+y^2)(2x^3+y)(−2x^3+y)

The cylinder's total surface area includes the area of the curving surface as well as the areas of the two circle-shaped bases of the cylinder.
The area of the two bases and the area of the curved surface are added to determine the cylinder's total surface area. Consequently, the following is the formula for the cylinder's total surface area:
Area of the two bases plus the area of the curved surface equals the cylinder's total surface area. Due to the cylinder's round bottoms, their combined area will be equal to r2 + r2. We already know that a cylinder's curved surface area is 2rh.
(r2 + r2 + 2rh) is the cylinder's total surface area.
⇒ 2πr2 + 2πrh
Total surface area of cylinder = 2πr(r+h)
where,
r = radius of the cylinder
h = height of cylinder

Answer:
$63
Step-by-step explanation:
First, we find the percentage that he saves:
9 is 3/5 of 15 which is 60%, 9 is 60% of 15 which means he save 60% of the money that he earns so,
60% of 105 = 63
This means he saved $65 from the money he earned.
Hope this helps!
