The sum
as three consicutive
multplies of 11 is
363
there eltiples.
Answer:
Three consecutive multiples are 110,121 and 132 which has the sum of 363. 33C = 363; C = 33, By substituting C = 33 in numbers 11C, 11(C – 1) and 11(C + 1) we get values 110, 121, 132.
+) Six times the sum of a number and -1 is the same as 2 more than 8 times the number. Find the number.
Answer:
-4
Step-by-step explanation:
6(a+(-1)) = 8a + 2
then:
6(a-1) = 8a + 2
6*a + 6*-1 = 8a + 2
6a - 6 = 8a + 2
6a - 8a = 2 + 6
-2a = 8
a = 8/-2
a = -4
Check:
6(-4-1) = 8*-4 + 2
6*-5 = -32 + 2 = -30
Determine the solutions of the equation |x – 3| = 11. 1. Rewrite for two solutions: (x – 3) = 11, –(x – 3) = 11 Solve for x in each equation. What are the solutions to the equation? x = –14, –8 x = –14, 8 x = –8, 14 x = 8, 14
Answer: C. x=-8,14
Step-by-step explanation:
C
Answer:
x = 14, –8Step-by-step explanation:
|x – 3| = 11
(x - 3) = 11 - (x - 3) = 11
x - 3 = 11 - x + 3 = 11
x = 11 + 3 -x = 11 - 3
x = 14 -x = 8
x = -8
A hockey game had 2,058 fans Friday night. The baseball game has 1,300 fans that night. How many more fans were at the hockey game?
Subtract the number at the baseball game from the hockey game:
2058 - 1300 = 758
There was 758 more people at the hockey game.
Answer:
758 more fans were there
Step-by-step explanation:
Difference = Hockey fans - Baseball fans
= 2058 - 1300
= 758
Reginald has to put fertilizer on his yard. The bags of fertilizer cost $4.79 and cover 3500 square feet. Reginald's yard is a rectangle that measures 427 ft by 231 ft. How much will he spend on fertilizer?
He'll spend 138.91 dollars.
First multiply 427 and 231 to find out how much square feet you need to cover. Then divide the number by 3500 to see how many bags of fertilizer you need. Since there is a remainder, he'll have to buy another bag. Then, multiply the number of bags needed with the price of each bag to get the amount of money spent.

-3(2y+4) is greater that equal to 12-4y
Answer:
y is less than or equal to -12
y<=-12
Step-by-step explanation:
Answer:
y≤12
Step-by-step explanation:
-3(2y+4)≥12-4y
-6y-12≥12-4y
-6y+4y≥12+12
-2y≥24
-2y÷2≤24÷2 (You have to flip the sign if you multiply or divide by a negative number)
y≤12
Write the slope-intercept form of the given line. Include your work in your final answer. Type your answer in the box provided to submit your solution.
Answer:
y = -3 ÷ 2x - 3
Step-by-step explanation:
As it can be seen that the line is passed by y-axis at -3.
Now we have to determine the slope
For this, use the following formula
= (x2 - x1) ÷ (y2 - y1)
At
(-2, 0), (0, -3)
So,
= (-3-0) ÷ (0+2)
= -3 ÷ 2
Now
Put in the following equation
y = mx + b.
where,
m = slope
b = y-intercept
So,
y = -3 ÷ 2x - 3
A tree is 4 1/2 feet tall, it is expected to grow by 1 3/4 feet per year at this rate how long will it take for the tree to have a height greater than 40 feet
Answer:
Approximately
n = 21 years
Step-by-step explanation:
Original height of the tree = 4 1/2 feet
Final height of the tree = 40 feet
Common difference = 1 3/4 feet per year
The data shows the question is an arithmetic progression
Tn = a + (n-1) d
Tn = 40
a = 4 1/2
d = 1 3/4
n = ?
Tn = a + (n-1) d
40 = 4 1/2 + ( n - 1) 1 3/4
40 = 9/2 + (n - 1) 7/4
40 = 9/2 + 7/4n - 7/4
40 = 18-7/4 + 7/4n
40 = 11/4 + 7/4n
40 - 11/4 = 7/4n
160-11/4 = 7/4n
149/4 = 7/4n
Divide both sides by 7/4
n = 149/4 ÷ 7/4
= 149/4× 4/7
= 149/7
n = 21.29 years
Approximately
n = 21 years

If DE bisects <ABC.find the value of x if m<ABC=7x+29 and m<DBC=99°
Answer:
19
Step-by-step explanation:
If DE bisects <ABC, this means that <ABE = <EBC
Also <DBC+<EBC = 180
99+<EBC = 180
<EBC = 180-99
<EBC = 81
Also <ABC =<ABE+<EBC
<ABC =<EBC+<EBC
7x+29 = 81+81
7x = 162-29
7x = 133
x = 133/7
x = 19°
Hence the value of x is 19°
h(x)=-3x+1
evaluate h(-2)
Answer:
h(-2) = 7
Step-by-step explanation:
Plug in -2 for h in the equation:
h(x) = -3x + 1
h(-2) = (-3)(-2) + 1
Remember to follow PEMDAS. First, multiply, then add:
Multiply. Note that when you multiply two negative numbers, the answer will be positive:
(-3) * (-2) = (3 * 2) = 6
Next, add:
h(-2) = 6 + 1 = 7
h(-2) = 7
h(-2) = 7 is your answer.

Use the pattern to extend the table. Then answer the question below. Include two decimals for each answer even if they are 0 Cars Washed Money Earned (Hint: this is how much you would earn for 1 car) How much is earned per car? $ How much will be earned for 20 cars?
We know that 3 cars yielded $13.50
$13.50 / 3 = $4.50 / 1 car
$4.50 * 12 cars = $54.00
$4.50 * 15 cars = $67.50
$4.50 * 20 = $90.00
Solve -4(3x – 7) = 52 for x.
Answer:
x = -2
Step-by-step explanation:
First, distribute:
-12x + 28 = 52
Then, subtract 28 on both sides:
-12x = 24
Finally, divide -12 on both sides:
x = -2
Hope this helps!
Answer:
Your answer is x= -2
Step-by-step explanation:
[tex]-4(3x-7)=52[/tex] divide both sides by -4
[tex]\frac{ -4(3x-7)}{-4} = \frac{52}{-4}[/tex] cross out -4 and divide 52 by -4= -13
[tex](3x-7) = -13[/tex] add 7 to both sides -13+7=-6
[tex]3x= -6[/tex] divide both sides by 3
[tex]\frac{3x}{3} = \frac{-6}{3}[/tex] cross out the 3 and divide -6 by 3 = -2

Answer:
I believe the answer is $1702.50.
Step-by-step explanation:
If you multiply 1500 by 4.5% (0.045 as a decimal) you will get 67.5 which is $67.5 interest for one year. For three years, you have too multiply 67.5 by 3 and you get $202.5. Finally, you add the total interest to the starting amount, $1500, which results in $1702.50.
how to find out L C M of common division method
Step-by-step explanation:
To find the LCM by division method, we write the given numbers in a row separately by commas, then divide the numbers by a common prime number. We stop dividing after reaching the prime numbers. The product of common and uncommon prime factor is the LCM of given numbers.
For example
2 24,12
2 12,6
2 6,3
3 2,1
2 1,1
LCM=2×2×2×3×2
