What is x in this problem ?
Answer:
is it just -12
because -12 +122 = 110
PLEASE HELP!! QUESTION IS IN IMAGE
Answer:
false and then true
Step-by-step explanation:
Hope this helps :)
Answer:
First one is False, second one is true.
Step-by-step explanation:
For the first one, the left side of the equation would equal -6/3, and the left side would be 3/-6. When simplified it would be: -2 = -1/2, which is incorrect.
For the second one, the left side and the right side are the same because either way you put it, they are still being multiplied, and the order doesn't matter. The end result will be -72 = -72, which is correct.
I hope this helps!! :>
steve baked 5 1/2 batches of cookies in one and one half hours. Vondra baked 3 1/3 batches of cookies in 11/12 hour. Which baker made cookies at a greater rate of batches per hour?
Answer:
Step-by-step explanation:
Steve 11/2 batches / 3/2 hrs = 11/2(2/3) = 11/3 = 3 2/3 = 3 22/33 batches/hr
Vondra 10/3 batches / 11/12 hr = 10/3(12/11) = 120/33 = 3 21/33 batches/hr
Steve had a very slightly faster batch rate by only 1/33 batch/hr
On a field trip, the ration of students who brought a water bottle to those who didn’t was 7 to 4. If 60 students did not bring water bottle, determine the total number of students on the field trip.
Answer:
165 students
Step-by-step explanation:
7/4 = x/60
(60*7)/4 = 105
105 + 60 = 165

Answer:
9 is 50% of number 18
'cuz u should do 18/2=9
Answer:
9 / 50% = Y / 100%
Solve for Y
50Y = 9 x 100
50Y = 900
Y = 900 /100 = 18

help asap plsssssssssssssssssssssssssss. Find the missing parts of each number line. Assume that the lines have been split into equal parts.
Answer:
16 for the first one. each segment is 4
40 for the second. each segment is 8
Answer:
0, 4, 8, 12, 16
8, 16, 24, 32, 40, 48
Step-by-step explanation:
The first number line has 6 parts. 24÷6=4. Each vertical line will increase by 4.
So starting at 0, the parts of the number line are:
0, 4, 8, 12, 16, 20, 24
The specific part being asked for is 0, 4, 8, 12, 16
The second number line has 8 parts. 64÷8=8. Each vertical line will increase by 8.
Starting at 0, the parts of the number line are:
0, 8, 16, 24, 32, 40, 48, 56, 64
The specific part being asked for is 8, 16, 24, 32, 40, 48
Help please …………….urgent :)
Answer:
The speed of the boat in still water is 12 miles per hour, while the speed of the current is 9 miles per hour.
Step-by-step explanation:
We'll use x as the speed of the boat in still water in miles per hour.
We'll use y as the speed of the current in miles per hour.
When the boat is traveling downstream, the speed of the boat is helped by the speed of the current and the net speed is x + y.
When the boat is traveling upstream, the current opposes the movement of the boat, and the net speed is x - y.
Using a table where d = distance in miles, r = rate or speed in miles per hour, and t = time in hours can help figure out how to figure out this problem.
─────────────────
Downstream│210│(x + y)│10
Upstream│210│(x - y)│70
─────────────────
Recall that distance = rate x time or d = rt.
210 = (x + y)10 ➤ Equation from downstream information.
210 = (x - y)70 ➤ Equation from downstream information.
210 = 10x + 10y ➤ Distribute.
210 = 70x - 70y ➤ Distribute.
7 × 210 = 7 × 10x + 7 × 10y ➤ Multiply the 1st equation by 7.
1470 = 70x + 70y ➤ Add the 1st equation to the 2nd.
210 =70x - 70y ➤ Add the 1st equation to the 2nd.
1680 = 140x
─────────────────
1680/140 = 140x/140
x = 12
210 = (12 + y)10 ➤ Substitute x = 12 into one of the original equations to find y.
210 = 120 + 10y
-120 - 120
90 = 10y
90/10 = 10y/10
y = 9
Find the slope and y-intercept for this table.
Answer:
Slope is -5 and y-intercept is 90.
Step-by-step explanation:
Use the two values that you circles (4, 70) and (6, 60) .
slope (m) = the change in y-value/ (the change in the x-values).
m = (70 - 60)/(4 - 6) = 10/-2 = -5
The y-intercept is the value of "b" in the equation y = mx + b.
Using y = mx + b, substitute the value m and use point of your points (4, 70).
y = mx + b
70 = -5(4) + b Now solve for "b".
70 = -20 + b
+20 = +20
90 = b
Evaluate the expression when a = 2 and b = 5.

6t - 20 - 32u when t = 6 and u = 1/4
Answer: 8
Step-by-step explanation:
Substitute the variables for the number they represent
6(6) - 20 - 32(1/4)
Multiply
6*6 = 36
32 x .25 = 8
36-20-8
16-8
8
Answer:
here given equation is 6t - 20 - 32u
value of t=6
value of u=1/4
then...
putting the value in the given equation.. we get,
=6*6-20-32*(1/4)
=36-20-8
=8

Which equation matches the graph of the greatest integer function given
below?
Answer:
D. y = [x] - 2
Explanation:
The Greatest Integer Function is denoted by y = [x].
For all real numbers, x, the greatest integer function returns the largest integer less than or equal to x. In essence, it rounds down a real number to the nearest lowest integer.
In the plot of y = [x], the plot starts from origin because y = [0] = 0.
But, in the question, all the lines are shifted 2 units downward, as it starts from (0, -2).
i.e for every values of x, y moves two units down
So our answer is y = [x] - 2.

Hope this helps, good luck! :D

Answer:
1/2 = 0.5 and 3/4 = 0.75
Use a proportion: 0.5/2.60 = 0.75/x
Cross multiply: 0.5x = 0.75*2.60
So x = 0.75*2.60/0.5 = 3.90
the quadratic x2-4x-21 can be witten in the form (x+a)2 +b find the values of a and b

[tex]\\ \sf\longmapsto x^2-4x+4-25[/tex]
[tex]\\ \sf\longmapsto x^2-4x-21[/tex]
Answer:
a = - 2, b = -25Step-by-step explanation:
Given quadratic expression:
x² - 4x - 21Convert this into vertex form:
x² - 4x + 4 - 25 = (x - 2)² - 25Compare this with the vertex form to determine the values of a and b:
a = - 2b = -25Can Defects A company that makes soda pop cans finds that the
probability of producing a can without a puncture is 0.96, the probability that
a can does not have a smashed edge is 0.93, and the probability that a can
does not have a puncture and does not have a smashed edge is 0.893.
(a) Are the events "selecting a can without a puncture" and "selecting a can
without a smashed edge" mutually exclusive? Explain.
(b) If a quality inspector randomly selects a can, find the probability that the
can does not have a puncture or does not have a smashed edge
Using probability concepts, it is found that:
a) Since [tex]P(A)P(B) \neq 0[/tex], the events are not mutually exclusive.
b) 0.997 = 99.7% probability that the can does not have a puncture or does not have a smashed edge.
Item a:
Two events, A and B, are mutually exclusive if:
[tex]P(A \cap B) = 0[/tex]
In this problem:
Event A: No puncture, thus, [tex]P(A) = 0.96[/tex].Event B: No smashed edges, thus [tex]P(B) = 0.93[/tex]The problem also states that the probability of neither is [tex]P(A \cap B) = 0.893[/tex].
Since [tex]P(A)P(B) \neq 0[/tex], the events are not mutually exclusive.
Item b:
Using Venn probabilities, the "or" probability is given by:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
With the given values:
[tex]P(A \cup B) = 0.96 + 0.93 - 0.893 = 0.997[/tex]
0.997 = 99.7% probability that the can does not have a puncture or does not have a smashed edge.

Can you please help me with #4-#5?I don't know how to find the answer.
Answer:
Step-by-step explanation:
4:C(X) = 17x - 10, the first question wants you to find how much 5 ticket costs, so replace x with 5 so c(x)= 17(5)-10 which equals 75$
4a: 4a wants you to find how many tickets you can buy for 130$. So first replace the y or c(x) with 130 x, which gives 130=17x-10. Now we find x, first add 10 to both sides to cancel the -10, 140=17x, then divide 17 from both sides which gives 8.235, so we can buy 8 tickets.
4b: It is discreet because it cannot be broken down into decimals or fractions, since you cannot have a halve of a ticket.

Answer:
5 five dollar and 7 one dollar
Step-by-step explanation:
let the number of one dollar be xthe number of five dollar be y1x+5y=32
x+y=12
using elimination method
+x-x-y+5y-32+12=0
4y-20=0
4y=20
divide both side by 4y=20/4 =5
so, if. y is 5 then x is
5y+x=32
5(5)+x=32
25+x=32
x=32-25
x=7
