Answer:
x > -22/7
Step-by-step explanation:
Given inequality:
- 7x - 15 < 6
adding 15 to both sides:
==> -7x - 15 + 15 < 6 + 16
==> -7x < 22
dividing both sides by 7:
==> -x < 22/ 7
multiplying both sides by -1
(anytime you multiply the inequality by -1 you must flip the inequality sign– replace the "<" with ">")
==> x > -22/7
Karen wants to order lunch for herself and some friends. Sam’s Deli charges $5 per sandwich plus $8 for delivery. Quick Lunch Deli charges $6 per sandwich plus $4 for delivery. How many sandwiches would Karen have to purchase to make the total cost of lunch the same?
Answer:
4 sandwichesStep-by-step explanation:
Let the number of sandwiches is x.
We have the following equation:
5x + 8 = 6x + 46x - 5x = 8 - 4x = 4Answer: The answer is She would have to buy 20 sandwiches. which is $200. She's buying those rich sandwiches.
Step-by-step explanation: I used a graph and added till I got the number the same for both which was 200 I hope this helps have a great day!
Andy and Sylvie each incorrectly simpilfied the expression: -3-4(2x-3).
Andy : -14x + 12
Sylvie: -8x - 6
Explain the errors and give the correct answer.
1. Observe problem
2. Simplify
-3-4(2x-3)
expand by distributive property
-3-8x+12
addition and subtraction
-8x+9
I have no idea what Andy And Sylvie were doing, so therefore...
I don't know which brain cell in there head is dysfunctional.
Answer:
-9 - 8x
Step-by-step explanation:
Andy multiplied incorrectly it should have been -4*2x, -4*-3
Sylvie forgot to multiply both sides she did -4*2x but forgot to do -4*-3
The correct answer should be...
-3-4(2x-3)
-3 - 8x + 12
-9 - 8x
What is the exact value of 5 5/6 - (1 1/4 + 3 7/8)?

C. 8 11/24
D. 10 23/24
Which expression is equivalent to 3^-2 times 5^-2
a. 1/15^2
b. 1/15^-2
c. 15^4
d. 15^-4
Answer:
The answer would be A)
Step-by-step explanation:
3^-2 = 1/9
5^-2 = 1/25
1/9 * 1/25 = 1/225
15^2 = 225
meaning,
3^-2 * 5^-2 = 1/15^2

Answer:
10.Step-by-step explanation:
63 cookies = 9 scoops of flour.If we go up once with another scoop of flour,
you should get this:
70 cookies = 10 scoops of flour.A welder needs a piece of half inch pipe 14 3/8 inch long. She has a peace that is 25 1/16 inch long how much must she cut off from the longer piece?
well, the longer piece is clearly the latter, so let's firstly convert the mixed fractions to improper fractions and then subtract.
[tex]\stackrel{mixed}{14\frac{3}{8}}\implies \cfrac{14\cdot 8+3}{8}\implies \stackrel{improper}{\cfrac{115}{8}} ~\hfill \stackrel{mixed}{25\frac{1}{16}}\implies \cfrac{25\cdot 16+1}{16}\implies \stackrel{improper}{\cfrac{401}{16}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{401}{16}~~ - ~~\cfrac{115}{8}\implies \implies \cfrac{(1)401~~ - ~~(2)115}{\underset{\textit{using this LCD}}{16}}\implies \cfrac{171}{16}\implies 10\frac{11}{16}[/tex]
In the figure below, XZ=35 and YZ=17. Find XY.
Answer:

To make a perfect square of v² - 14v , add c such that:
We have:
a = 1 b = - 14 c = b²/ (4a) = (-14)²/ (4 × 1) = 49⇒ v² - 14v + 49 = (v - 7)(v - 7) = (v - 7)²
Answer: 49

Determine whether the following statement is true or false.
The ordered pairs (8,- 9) and (-9,8) name the same point.
Hi!
I can help you with joy!
Are these ordered pairs the same? Do they name the same point?
(8, -9) and (-9,8) are our points.
The x-coordinate of one point is 8, and the x-coordinate of the second point is -9.
The y-coordinate of the first point is -9, and the y-coordinate of the second point is 8.
Thus, these 2 ordered pairs do not name the same point.
The statement is false.
I hope this helps!
Ask me if you have any questions or doubts.

There are 21 students in class. The median age of the students is 23. The oldest student is 29
Please explain
Answer:
At least one student is 23: Must be true
Some students are younger than 15: Could be true
Step-by-step explanation:
Statement 1: A median is a number in the middle for ex. 1, 2, 3, 4, 5 in this example 3 is the median. Another ex could be 1, 2, 3, 4, 5, 6. This time you would have to add (3 + 4), divide by 2, which equals 3.5.
Since there are 21 students in class making it an odd number 23 must be true.
Statement 2: Based on the information I am given, I would say could be true because the difference between the oldest and the median is 29 - 23 = 6 so it could be true.
Answer:
1) At least one (the 11th) student is 23 (years old), Must be true
2) Some students are younger than 15 Could be true
Step by step explanation:
1) The given parameters are;
The number of student in the class = 21
The median age of the student = 23
The age of the oldest student = 29
Therefore, given that the median age = The age of the (n + 1)/2 the student
Where;
n = The number of student in the class = 21
The median age = The age of the (21 + 1)/2 th = 11 th student, when the age of the students are arranged in increasing order, therefore, we have;
At least one (the 11th) student is 23 (years old), Must be true
2) Given that there are 10 students with ages equal to or lower than the median age, and the difference between the median age and the age of the oldest student = 29 - 23 = 6 years, we have;
Some students are younger than 15 Could be true
The width, W , of a rectangle is 4 less than 6 times the length, which would find the area.
Group of answer choices
Solution:
Note that:
W = 6L - 4Area = LWSubstitute the value of W into the formula (Area = LW).
Area of rectangle = LWArea of rectangle = L x WArea of rectangle = L x (6L - 4)Area of rectangle = L(6L - 4)Option C is correct.
Suppose that 12 inches of wire costs 48 cents.
At the same rate, how much (in cents) will 31 inches of wire cost?
Answer:
It will cost 124 cents to buy 31 inches of wire.
Step-by-step explanation:
12 inches costs 48 cents
1 inches will cost her [tex]\frac{48}{12}[/tex] → 4 cents
Then 31 inches will cost: 31 * 4 → 124 cents
Answer:
124 centsStep-by-step explanation:
Solve using ratios since this is a proportional relationship:
12/48 = 31/x1/4 = 31/xx = 31*4x = 124 cents3/10 of a bag of jelly beans 2/10 and of the bag were orange. What fraction of the bag was red and orange
Answer:
1/2 of the bag would be red and orange.
Step-by-step explanation:
if 3/10 of the bag was red
and 2/10 was orange, then all you have to do is the add the number of jelly beans that are red and orange,
3/10 + 2/10 is 5/10
simplify and that will get you to 1/2
Answer:
Step-by-step explanation:
if 3/10 of the bag was red
and 2/10 was orange, then all you have to do is the add the number of jelly beans that are red and orange,
3/10 + 2/10 is 5/10
simplify and that will get you to 1/2
You have been sent to grocery shop. They gave you $25.00 and the list of what
you need to buy, would you need more money or would you have enough money?
Here is the grocery list:
2 pounds of ham: $4.59/pound
3 bags of chips: $3.00/bag
2 loaves of bread: $1.99/loaf
Please calculate the above and write down how much it equals and what you will
have left after you buy it.
Answer:
you would have $2.98 left
Step-by-step explanation:
$4.59 x 2=9.18
3.00 x 3=9.00
$1.99 x 2=3.98
$9.18+$9.00+$3.98=22.16
$25.00-$22.16 = $2.89

Ms. Jacobi writes the equation x+y=z. If x = 5, y = 3, and z = 53,
is the equation true? Explain your reasoning.
Answer:
no
Step-by-step explanation:
Because if we substitute the value of x,y and z we get
x+y=z
5+3=53(FALSE)
Answer and Step-by-step explanation:
No, this equation is not true. But in order to show this, we need to write out the equation. So if x = 5, and y = 3, then the equation for this equation would look like this:
5 + 3 = 8.
That is incorrect because 5 + 3 does not equal 53. This is a trick question that is trying to trick you. Now if that 5 was a 50, then this equation would be true.
So, 5 + 3 ≠ 53.
I hope that this helps.
