Select the correct answer.
A mistake was made in the steps shown to simplify the expression.
Which step includes the mistake?
9/2 + 3(4-1) -7 + 2³
Step 1: 9/2 + 3(3) -7 + 2³
Step 2: 9/2 + 3(3) -7 + 8
Step 3: 15/2 (3) -7 + 8
Step 4: 45/2 -7 + 8
Step 5: 31/2 + 8
Step 6: 47/2
A. Step 4
B. Step 3
C. Step 1
D. Step 5
Step-by-step explanation:
To determine where the mistake occurred let's solve the expression ourselves and compare with answer L's given.
9/2 + 3(4-1) -7 + 2³
Using BODMAS = Bracket, Of, Division, Multiplication, Addition and Subtraction.
Step 1: solve for the value in the bracket. 4-1 =3
9/2 + 3(3) -7 + 2³
Step 2: find the value of 2³
2³ = 2×2×2 = 8
9/2 + 3(3) -7 + 8
Step 3: add 9/2 and 3(3)
9/2 + 3(3) = 9/2 + 9 = (9+18)/2
= 27/2 = (9/2)(3)
9/2 (3) -7 + 8
Step 4: open the bracket
27/2 -7 + 8
Step 5: subtract 7 from 27/2
= (27-14)/2 = 13/2
13/2 + 8
Step 6: add 13/2 and 8
13/2 + 8 = (13+16)/2 = 29/2
From the above calculation, the mistake occurred in (B) Step 3
1/5 of $60 is $12.
Therefore, 2/5 of $60 is $24.
If the price of tickets increased by 2/5 during the World Series, then during the World Series a ticket would've cost $60+$24=$84.
Answer:
A. -24
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a directly or proportional variation if it can be expressed in the form 
or 
In this problem we have
For x=-3, y=12
Find the value of the constant of proportionality k
substitute the given values
so
The linear equation is equal to
what is the value of y when x=6?
substitute the value of x in the linear equation and solve for y
Answer:
5960 pesos
Step-by-step explanation:
We can write a proportion
298 pesos --- $25
x pesos --- $500
x=298*500/25 = 298*20 = 5960 pesos
Answer:
Length = 4 inches
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
If x = 2
Perimeter = 8x - 4
= 8(2) - 4
= 16 - 4
= 12 inches
Width = 3x - 4
= 3(2) - 4
= 6 - 4
= 2 inches
Perimeter of a rectangle = 2(length + width)
12 = 2(length + 2)
12 = 2length + 4
12 - 4 = 2 length
8 = 2 length
Length = 8/2
Length = 4 inches
