Answer:
27 28 29
Step-by-step explanation:
Let the first be n , and if they are consecutive then the next two numbers are n+1 and n+2.
n+(n+1)+(n+2)=84.
3n+3=84.
⇒3n=81.
⇒n=27.
Hence numbers are n,n+1,n+2→27,28 and 29
2x-(180-x)= 27
2x-180+x= 27
3x-180=27
3x=207
x= 69
Final answer: 69 degrees
Answer:
C. SUBTRACT (2x) from both sides in the bottom equation
Step-by-step explanation:
Given
Required
The first step of a substitution method
In the second equation, notice that the coefficient of y is 1.
So, the first step is to make y the subject of the formula.
This is achieved by subtracting 2x from both sides of the equation.
<em>Hence: (c) is true</em>
Answer:
200ft^2
Step-by-step explanation:
From the first sentence;
L = 2B
Perimeter of a rectangle = 60ft
P = 2[ L +B ]
substitute as follows;
60 = 2( 2B + B)
60 = 2(3B)
60 = 6B
B = 10ft
To find L
L = 2B
L = 2*10
L = 20 ft
Area of a rectangle = LB
= 20×10
=200ft^2
Answer:
120 = 3y + t
Step-by-step explanation:
120 = 3y + t because you purchase 3 times as many y then t. Overall, your answer should end up as 120 by using an equation like this.
