Four people when to the concert and two of them purchased a t-shirt. Which expression could you use to determine the total amount spent if a concert ticket is $30 and a t-shirt is $20. *
4(30 + 20)
4(30) + 4(20)
4(30) + 2(20)
6(50)
Answer:
160 dollars
Step-by-step explanation:
4 people went to the concert
the concert ticket is 30
30 times 4 is 120
2 people got a t shirt
A t shirt is 20
20 times 2 is 40
120 plus 40 is 160

3.1 Adding fractions which have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
24x - (84) 24x - 84
—————————— = ————————

STEP 4:
Pulling out like terms :
4.1 Pull out like factors :
24x - 84 = 12 • (2x - 7)
Equation at the end of step 4:
12 • (2x - 7)
————————————— = 0

The equation now takes the shape :
12 • (2x-7) = 0
Equations which are never true:
5.2 Solve : 12 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
5.3 Solve : 2x-7 = 0
Add 7 to both sides of the equation :
2x = 7
Divide both sides of the equation by 2:
x = 7/2 = 3.500
x = 7/2 = 3.500
What is the approximate distance between the points (–5, 4) and (2, –8)?
A. 12.0 units
B. 19.0 units
C. 9.7 units
D. 13.9 units
Answer:
option d is the correct answer
Step-by-step explanation:
Distance Equation Solution:
d=radical(2−(−5))2+(−8−4)2
d=radical(7)2+(−12)2
d=radical49+144
d=radical 1–93
d=13.892444

Explain how to solve the equation and then check the solution.
9 = q – 4
Sample Response: Use the inverse operation to isolate the variable. Undo the subtraction of 4 by adding 4 to both sides of the equation. –4 + 4 = 0, and 9 + 4 is 13. The solution is q = 13. Check the solution by substituting 13 for q in the original equation, and then simplify. 13 – 4 is 9 and 9 = 9 is a true statement, so 13 is the solution.
Answer:
Use the inverse operation to isolate the variable. Undo the subtraction of 4 by adding 4 to both sides of the equation. –4 + 4 = 0, and 9 + 4 is 13. The solution is q = 13. Check the solution by substituting 13 for q in the original equation, and then simplify. 13 – 4 is 9 and 9 = 9 is a true statement, so 13 is the solution.
Step-by-step explanation:
The solution of the Equation 9 = q – 4 is 13.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
9 = q – 4
We have to use the inverse operation as
Addition inverse Subtraction and vice versa.
Division inverse Multiplication and vice versa.
So, 9 = q – 4
Undo the subtraction of 4 by adding 4 to both sides of the equation.
9 + 4 = q- 4 +4
13 = q
Hence, the solution is 13.
