Answer:
the first answer is 10 and the second is 40
Step-by-step explanation:
there actually asking how many meters would make 1 centimeter
On the ruler 1 whole centimeter is 10 meter. (The longer line behind the number is the 10th meter )
Dividing fractions
1 ÷ 1/10
Steps
Change the whole number which is 1 into a fraction.
1/1 ÷1/10
Flip the second fraction in the equation.
1/1 ÷ 10/1
Then change the division sign to a multiplication sign. So were multiply instead.
1/1 × 10/1
Multiply the fractions and your answer should be 10/1 .
This fraction is also changed to a whole number.
10/1 = 10
Angle A = 3x - 10
Angle B = x
Their angle sum = 90° ( complementary angles form 90° )
This can be written in an equation as =
= 3x - 10 + x = 90
= 3x + × + ( -10 ) = 90
= 4x + (-10) = 90
= 4x = 90 + 10 ( transposing-10 from LHS to RHS changes-10 to +10 )
= 4x = 100
= x = 100 ÷ 4 ( transposing ×4 from LHS to RHS changes ×4 to ÷4 )
= x = 25
Angle A = 3x - 10
= 3 × 25 - 10
= 75 - 10
= Angle A = 65°
Angle B = x = 25°
Their sum = 65 + 25 = 90°
Therefore , the complementary angles , Angle A = 65° and Angle B = 25° .
