Answer:
-88 and -87
Step-by-step explanation:
Since the two unknown integers are consecutive, one will be one more than the other. This means we can express them as x and x+1, so we only have one unknown in our equation. Since they add to -175, we can now write our equation:
x+(x+1) = -175
Take away brackets and combine like terms:
2x+1 = -175
Now we just need to isolate x which we can do by subtracting 1 from both sides and then dividing both sides by 2:
2x+1-1=-175-1
2x = -176
2x/2 = -176/2
x = -88
And our other number is -88+1 = -87
So our two numbers are -88 and -87 which are consecutive and add to 176:
-88+(-87) = -175

Answer ↷(5,12)
Solution ↷Given that,
3x + 2y = 39......(1)
5x - y = 13.......(2)
multiplying equation 1 by 5 & 2nd by 3 ,we get,

A clock shows time as 1:10pm is 20 minutes fast what is the correct time
Answer:
12:50
Step-by-step explanation:
in time after 60 minutes it goes to the next hour
so since is 20 minutes faster we are going to take it back 20 minutes backward
--› 1:10{when going backwards after 1:00 is 12:59}
--› 1:10 - 20
--› 12:50
The correct time on the clock is given by the equation A = 12 : 50 PM
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the correct time on the clock be represented as A
Now , the equation will be
The present time on the clock P = 1 : 10 PM
And , the time on the clock is 20 minutes faster than the actual time
So , substituting the values in the equation , we get
The correct time on the clock is given by A = present time on the clock P - 20 minutes
On simplifying the equation , we get
The correct time on the clock is given by A = 12 : 50 PM
Therefore , the value of A is 12 : 50 PM
Hence , the equation is solved

7500 in account paying 1.5 compound interest, how much after 8 years
Answer:
The amount of money after 8 years is $8448.69
Step-by-step explanation:
The rule of the compound interest is
[tex]A=p(1+r)^{t}[/tex] , where
A is the new valueP is the original valuer is the rate in decimalt is the time in years∵ There is $7500 in an account
∴ P = 7500
∵ The account paying 1.5% compound interest
∴ r = 1.5% = 1.5/100 = 0.015
∵ The money will invest for 8 years
∴ t = 8
→ Substitute all of these values in the rule above to find A
∵ [tex]A=7500(1+0.015)^{8}[/tex]
→ Use your calculator to find the answer
∴ A = 8448.69
∴ The amount of money after 8 years is $8448.69

A researcher collected data from car shoppers about their favorite car color. He asked 250 people about their favorite vehicle color. How many more people said their favorite color is white compared to those who said black. Your answer should be written as a number not a percentage. And then the percents for the circle graph are 20% red 24% white 32% blue 18% black 4% silver and 2% other
Answer:
35 more preferred white
Step-by-step explanation:
Black 18% * 250 = 18/100 * 250 = 45
White 32%*250 = 32/100 * 250 = 80
The difference is 80 - 45 = 35
If the salinity of ocean water at the entrance to an estuary is 35 and 63 percent of the volume of water in the estuary is ocean water, what is the average salinity of the estuary
The correct answer for the average salinity of the estuary would be 22.235.
Given in the question,
Salinity of ocean water at the entrance to the estuary: 35.
Volume of ocean water in the estuary: 63% (or 0.63).
Volume of freshwater in the estuary: 37% (or 0.37).
Consider, salinity of freshwater as 0.5.
To calculate the average salinity of the estuary, the formula know is:
Average Salinity = (Salinity of Ocean Water * Volume of Ocean Water + Salinity of Freshwater * Volume of Freshwater) / Total Volume of Estuary
[tex]= \dfrac{35*0.63 + 0.5 * 0.37}{1}\\\\= 22.05 + 0.185\\\\= 22.235[/tex]
Therefore, Average salinity of the estuary would be approximately 22.235.

The radii of two similar cones are 1 and 2.5. What is the ratio of their volumes?
Answer:
Assuming the cones are the same height, then
V1 = pi * r^2 * h/3 = 3.14159*1^2*h/3
V2 = 3.14159*2.5^2*h/3 = 3.14159*6.25*h/3
V1/V2=(3.14159*h/3)/(3.14159*6.25)*h/3
V1/V2 = 1/6.25 = .16
V2/V1=(3.14159*6.25)*h/3/(3.14159*h/3)
V2/V1=6.25/1 = 6.25

For a circle of radius R and center (a, b), the equation is given by:
(x - a)^2 + (y - b)^2 = R^2
With that in mind, if we look at the first equation:
(x + 3)^2 + (y + 5)^2 = 16 = 4^2
This is a circle centered at (-3, - 5) with a radius of 4 units.
For the second equation:
(x + 3)^2 + (y - 5)^2 = 4 = 2^2
The center is (-3, 5) and the radius is 2 units.
The third equation is:
(x - 3)^2 + (y - 5)^2 = 4 = 2^2
The center is (3, 5) and the radius is 2 units.
The fourth equation is:
(x - 3)^2 + (y + 5)^2 = 16 = 4^2

The cost of manufacturing a single DVD is represented by: C(x) = 0.35x+ 1.75. What is the cost of manufacturing 12 DVDs?
Answer:
£5.95
Step-by-step explanation:
To find the cost of 12 DVDs, let x = 12
C(12) = 0.35 x 12 + 1.75
C(12) = 4.2 + 1.75
C(12) = 5.95
The cost of manufacturing 12 DVDs is $5.95.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Given that, the cost of manufacturing a single DVD is represented by C(x) = 0.35x+ 1.75.

What is the Ratio?
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Clearly, from observation,
Each column represent geometric progression with common ratio r = 1/4. So when moving downward, the element in the rows decreases as multiple of 1/4.
Here,
R(1, 1) = 256
R (2 ,1) = 64
R(2,1)/R(1,1)=1/4

Ms. James bought 3 world maps for her classroom. The total cost of the 3 maps was $73.77. The clerk told Ms. James that each map cost $2.45. Do you agree with the clerks calculations? Explain your reasoning.
please help ASAP please will give branlyist if i can figure it out
Answer:
The clerk is wrong because the total cost per map is $24.59
Step-by-step explanation:
since you know that you spent $73.77 for 3 maps you can set up the equation 73.77 = 3X (where x = cost per map)
once you divide 73.77 by 3 you get 24.59 and that equals the price per map
if it was like the clerk said and each map was 2.45 then the total cost shoud have been 7.35.

(-6, 1)

Hey there!
In order to determine whether an ordered pair is a solution, all we have to do is plug in the values of x and y and see if we end up with a true statement.
The first pair is (-6, 1)
plug in 1 for y and -6 for x:
2(-6)+7(1)=-5
-12+7=-5
-5=-5
Yep! Here we have a true statement.
Therefore, this ordered pair is a solution.
2(9)+7(2)=-5
18+14=-5
Well, we can see that we have a false statement, because
32≠-5
and ≠ means "not equal to"
Let's try the third ordered pair.
2(8)+7(-3)=-5
16-21=-5
-5=-5
Great! We have another true statement :)
Let's try the last option.
2(-5)+7(-4)=-5
-10-28=-5
-38=-5
As we can see, we ended up with a false statement.
