•Using the formula the first term is a1 = −3
•Using the formula the second term is a2 = −1
•Using the formula the third term is a1 = 6
•Common difference formula:
a2 - a1 = (-1) - (-3) = 2
15% of 40
Of = Multiplication
15% Multiply by 40
Set up a equation
15/100= x/140
Cross Multiply
15* 140= 100*x
2100= 100x
Divide both sides by 100x
2100/100x= 100x/100x
X= 21
Answer:
x = 14
Step-by-step explanation:
Given
-
(x - 4) = - 2
Multiply both sides by 5 to eliminate the fraction
- (x - 4) = - 10 ← distribute parenthesis by - 1
- x + 4 = - 10 ( subtract 4 from both sides )
- x = - 14 ( multiply both sides by - 1 )
x = 14
Answer:
infinite number of solutions
4x dollars left bc 2.5x -3= 5.5 plus 1.5x plus 4=5.5 and together they equal to 11 and 15-11=4
