Total savings:-
.[tex]\\ \sf\longmapsto 396+213=609\$[/tex]
Answer:
$459Step-by-step explanation:
Mahni saved 6x in the first 6 weeks which is $213.
She saves in the next 6 weeks:
6*(2x - 30) = 12x - 180 = 2*6x - 180 = 2*213 - 180 = 246Total saving is:
213 + 246 = 459Let C(x)=600+60x be the cost to manufacture x items.Find the average cost per item, to the nearest dollar, to produce 30 items.
A) $315
B) $80
C)$1320
D)$330
Answer:
Correct answer: B: $80
Step-by-step explanation:
Given the function, C(x) = 600 + 60x, where:
C(x) = represents the total cost to manufacture x items
x = number of manufactured items
Substitute x = 30 into the given function:
C(30) = 600 + 60(30)
C(30) = 600 + 1800
C(30) = 2400 ← This represents the total cost to produce 30 items. We need to find out the average cost per item.
Thus, we need to divide $2,400 by 30 to get the average cost of producing each item:
$2,400 / 30 = $80
Therefore, the correct answer is B) $80

true or false? A subtraction expression with a positive integer and a negative can have a difference of zero
Answer:
False
Step-by-step explanation:
Subtracting a negative integer is equivalent to adding a positive integer. So adding a positive integer to a positive integer can never be zero.
What is the slope of (-6,7), (0,3)
Answer:
-2/3
Step-by-step explanation:
To find the slope, we use the formula
m = ( y2-y1)/(x2-x1)
= ( 3 -7)/( 0 - -6)
= (3-7)/(0+6)
= -4/6
= -2/3
Answer:
m = -2/3
Step-by-step explanation:
Here, we need to find the slope .
To find slope we are using slope formula .
Slope Formula, m = ( y² - y¹ ) / ( x² - x¹ )
Where, we have given
x¹ = -6 and x² = 0y¹ = 7 and y² = 3Now putting the given values in the formula.
Slope , m = ( 3 - 7 ) / ( 0 - (-6 ) )
m = ( -4 ) / ( 6 )Divide by 2.
m = -2 / 3Therefore, Your answer is -2/3.
3.687 times n equals 36.87
Answer:
n is 10 if that's what your asking
Answer:
n=10
Step-by-step explanation:
if you multiply 3.687 by ten, it carries the decimal place over making 36.87, so ten is the answer
The price of a toy usually costing £50 is increased to £65. Work out the percentage increase.
Unfortunately the answer doesn't seem obvious to me. If i could have the answer as quickly as possible it would be very helpful. Thank you
Answer:
115%
Step-by-step explanation:
115% percent increase in usual value, I may guess see other answrrs too
Answer:
30%
Step-by-step explanation:
The percentage increase is calculated as
[tex]\frac{increase}{original}[/tex] × 100%
increase = £65 - £50 = £15 , then
percent increase = [tex]\frac{15}{50}[/tex] × 100% = 15 × 2% = 30%

Plot the ordered pairs from the table.
The ordered pair is plotted in the graph attached in the solution.
Given that Timony has three friends, the table shows the time taken by him to reach at his friends place and the distance of the homes of each of his friend.
We need to plot the ordered pair formed by the time and distance on the graph,
The ordered pair are:
(5, 10)
(11, 15)
(18, 20)
Plot the ordered pairs on the graph according to the given values:
The first ordered pair is (5, 10). This means that Timony took 5 units of time to reach a friend's place that is located 10 units of distance away. Mark this point on the graph.The second ordered pair is (11, 15). Timony took 11 units of time to reach a friend's place that is located 15 units of distance away. Mark this point on the graph.The third ordered pair is (18, 20). Timony took 18 units of time to reach a friend's place that is located 20 units of distance away. Mark this point on the graph.Hence the ordered pair is plotted.

how to solve
-3(m-2)=-9
m= ?
9514 1404 393
Answer:
m = 5
Step-by-step explanation:
Recognize that the number on the right has -3 as a factor. Divide both sides of the equation by -3.
m -2 = 3
Add 2 to both sides of the equation:
m = 5
_____
Additional comment
Perhaps the conventional approach is to eliminate parentheses, then solve the resulting 2-step linear equation.
-3m +6 = -9
-3m = -15 . . . . . . subtract 6 (step 1)
m = 5 . . . . . . . . . divide by the coefficient of m (step 2)
Your baseball team is selling bags of popcorn to raise money for a trip. For each bag of popcorn you sell, $5 go.
to earn at least $125 for the trip. Write and solve an inequality that represents the numbers x of bags of popcorn you must sell to reach your

An inequality is:
125x>5
5x > 125
5x> 125
5x< 125
You must sell at least
bags of popcorn to reach your goal.
Answer: [tex]5x \geq 125[/tex]
You need at least 125$ so it would be 5x is larger or equal to 125
When solving for x divide both sides by 5
125 / 5 = 25
x = 25
