How do I mutiply 14(a+5+6b)
Answer:
14a + 70 + 84b
Step-by-step explanation:
Each term in the parenthesis is multiplied by 14, that is
= (14 × a) + (14 × 5) + (14 × 6b)
= 14a + 70 + 84b

Ronnie bought 6 ice cream cones for himself and his friends. Seventeen cents tax was added to the price of each cone. The total cost was $14.58.
What was the price of a cone before tax?
Enter your answer in the box.
Answer:
$2.26
Step-by-step explanation:
6 ice cream cones means the price is 6 time as much as on cone so divide by 6.
$14.58 total
/6 number of cones
$2.43 cost of a single cone
now, we remove the $0.17 tax
$2.43
-$ .17
$2.26
Answer:
226 cent
Step-by-step explanation:
Let x represent the price of a single cone
6×(x+17) = 1458
⇔ x+17 = 1458/6 =1 458÷6 = 243
⇔ x = 243 - 17 = 226
write the expression for twice a number y increased by 4
2y + 4 is the expression for twice a number y increased by 4
Solution:
Given statement is:
Twice a number y increased by 4
Let us convert the given statement into algebraic expression
Let the number be "y"
In the given statement,
Twice a number means "y" is multiplied by 2
"Twice a number" is translated as 2y
Also,
"Increased by" means added, Which means 2y is added to 4
Therefore,
Twice a number y increased by 4 is translated as 2y + 4
Thus the final equation becomes: 2y + 4

What is the equation of the line through (2,-4) and (0,4)
What is the equation of the line that is parallel to y = –4x + 3 and has a y-intercept of -1/3
The equation of the line that is parallel to given line is 12x + 3y = -1
Solution:
Given that, the line that is parallel to y = –4x + 3 and has a y-intercept of -1/3
Given equation of line is:
y = -4x + 3
Let us first find the slope of line
The equation of line in slope intercept form is given as:
y = mx + c ------- eqn 1
Where, "m" is the slope and "c" is the y intercept
On comparing the above slope intercept form with given equation of line, we get m = -4
Thus the slope of line with equation y = -4x + 3 is -4
We have to find the slope of line that is parallel to above line
We know that slopes of parallel lines are equal
Therefore, slope of line passing parallel to given line is -4
Now find the equation of line
[tex]\text{Substitute } m = -4 \text{ and } c = \frac{-1}{3} \text{ in eqn 1 }[/tex]
[tex]y = -4x -\frac{1}{3}\\\\3y = -12x -1\\\\12x + 3y = -1[/tex]
Thus the equation of line is found
