Jack has $65 to spend on art supplies. He needs to buy an easel that costs $18. He also wants to buy some canvases that cost $11 each
Which of the following inequalities represents the amount of money Jack can spend if he buys n canvases?
A:65 >(line underneath sign)18 + 11n
B:65 > 18 + 11n
С:65 < (line underneath sign) 18 + 11n
D:65 < 18 + 11n
Answer:
C
Step-by-step explanation:
Jack can spend less than or equal to. So C is correct.
The inequality represents the given situation is 65 ≥ 18 + 11n will be correct thus, option (A) is correct.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.
As per the given,
Total budget = 65
Total spent = 18 + 11n where n is the number of canvases.
Total spent ≤ total budget
18 + 11n ≤ 65
Hence "The inequality represents the given situation is 65 ≥ 18 + 11n will be correct".

He Martins have a solar energy system. The system produces 9.1 Kilowatts of energy each hour. The system produces electricity for 5 hours each day. How much energey, in KWh, will the system produce in 100 day?
Answer:
4550 kilowatt
Step-by-step explanation:
Given that :
Amount of energy produced per hour by solar energy system = 9.1 kw per hour
Number of hours for which electricity is produced per day = 5 hours
How much energy will be produced in 100 days
Number of kilowatt of energy produced per day:
Energy produced per hour * number of hours
9.1 kw per hour * 5 hours = 45.5 Kilowatt per day
In 100 days :
Daily energy produced * number of days
45.5 kilowatt * 100 days
4550 kilowatt
3(7 - 2x) - 19 - 5(4- x) = 3(8 - 6x) - 9x + 5(4- x)
Answer:
x=2
Step-by-step explanation:
3(7-2x)-19-5(4-x) = 3(8-6x)-9x+5(4-x)
or, 21-6x-19-20+5x = 24-18x-9x+20-5x
or, 21-19-20-6x+5x = 24+20-18x-9x-5x
or, -18-x = 44-32x
or, -x+32x = 44+18
or, 31x = 62
or, x = 62/31
or, x = 2
Answer:
Step-by-step explanation:
21-6x-19-20+5x=24-18x-9x+20-5x distribution property
-x-18=44-32x common factors
31x-18=44 add 32x to both sides
31x=62 add 18 to both sides
x=2 divide 31 to both sides(equals 2) so x equals 2

The radio hot 97 plays despacito ft Justin beiber every 5 minutes. Another station Z 100 plays despacito every 7 minutes. Both stations at 3:00 pm and time will it be when despacito at the same time
Answer:
The next time they would play despacito on both stations is after 35 minutes.
Hence, 3:00pm + 35
= 3:35 pm
Step-by-step explanation:
The radio hot 97 plays despacito ft Justin beiber every 5 minutes. Another station Z 100 plays despacito every 7 minutes. Both stations at start 3:00 pm and what time will it be when despacito at the same time ?
Find and list multiples of time that despacito plays Radio hot 97 and Station Z 100.
Hence, we find the Multiples of 5 minutes and 7 minutes until the first common multiple is found. This is the lowest common multiple.
Multiples of 5:
5, 10, 15, 20, 25, 30, 35, 40, 45
Multiples of 7:
7, 14, 21, 28, 35, 42, 49
Therefore, the first common multiple is found which is the lowest common multiple is 35
LCM(5, 7) = 35
The next time they would play despacito on both stations is after 35 minutes.
Hence, 3:00pm + 35
= 3:35 pm
Answer:
of course they play despacito that much lol

HELP ME PLEASE, ASAP I JUST NEED X !!
Answer:
x = 6 deg
Step-by-step explanation:
14x + 11 = 16x - 1 (corresponding angles, // lines)
-2x = -12
x = 6
Answer:
C
Step-by-step explanation:
16x - 1 and 4x + 11 are corresponding angles and are congruent, thus
16x - 1 = 14x + 11 ( subtract 14x from both sides )
2x - 1 = 11 ( add 1 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Substitute x = 6 into either of the 2 equal angles
Substituting into 14x + 11 , then
14x + 11 = 14(6) + 11 = 84 + 11 = 95° → C

The Jefferson band is selling baked goods to raise money for their trip. Their goa; is to profit at least $500. Each baked good sells for 2 dollars but costs $0.50 to make. How many baked goods will they have to sell to reach the goal?
Answer:
Break-even point in units= 334
Step-by-step explanation:
Giving the following information:
Desired profit= $500
Selling price= $2
Unitary variable cost= $0.5
To calculate the number of units to be sold, we need to use the following formula:
Break-even point in units= (fixed costs + desired profit) / contribution margin per unit
Break-even point in units= (0 + 500) / (2 - 0.5)
Break-even point in units= 334
Which expression is equivalent to (5x - 4)2?
Answer:
Step-by-step explanation:
the answer is 25x^2-40x+16
25x^2-40x+16 is equivalent to (5x - 4)^2.
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, we have,
(5x - 4)^2
we know,
(a-b)^2= a^2-2ab+b^2
by using this, we get,
(5x - 4)^2
=5x*5x-2*5x*4+4*4
=25x^2-40x+16.
Hence, 25x^2-40x+16 is equivalent to (5x - 4)^2.

Muriel says she has written a system of two linear equations that has an infinite number of solutions. One of the equations of the system is 3y = 2x – 9. Which could be the other equation?
2y = x – 4.5
y = x – 3
6y = 6x – 27
y = x – 4.5
Answer: B
Step-by-step explanation: If you divide the 3 Y to get Y by itself, you will divide 3 on both sides. So 2X/3=2X/3 and -9/3=-3
So it will be Y=2X/3-3

Use intercepts to graph the line described by the equation 2x − 2y = 8.
Answer:
y = x + 4
Step-by-step explanation:
Slope intercept : 2x - 2y = 8 = 2x 2x = 8 + 2y = 2x = 8 +2y = 2x-8 =2y is the sae as 2y = 2x -8 divide everything by 2 = 2x / 2 - 8/2 = 2y/2 = y = x-4
