Answer:
Step-by-step explanation:
a) Age of Jeff = j
Tina's age = j - 4
b) j = 15 years
Tina's age = 15 - 4 = 11 years
j = 20 years
Tina's age = 20 - 4 = 16 years
j = 58 years
Tina's age = 58 - 4 = 54 years

For tropical fish, aquarium water should be set to 76° F with an allowance of 4°.
a. Explain how to write an absolute value equation to represent this situation.
b. Explain the steps to solve the absolute value equation. What do the solutions represent?
Answers
Using absolute value, it is found that:
The absolute value equation that models the situation is: [tex]|T - 76| = 4[/tex]The two solutions, [tex]T = 72[/tex] and [tex]T = 80[/tex], mean that the temperature of the aquarium water must be between these two values.---------------------------
The absolute value function is defined by:[tex]|x| = x, x \geq 0[/tex]
[tex]|x| = -x, x < 0[/tex]
It measures the distance of a point x to the origin.---------------------------
Item a:
The temperature should be set to 76ºF with an allowance of 4ºF, thus, the absolute value of the difference between the temperature T and 76 should be 4, that is:
[tex]|T - 76| = 4[/tex]
---------------------------
Item b:
Here, it is needed to solve the equation.There are two solutions:
[tex]T - 76 = 4[/tex]
[tex]T = 80[/tex]
Or also:
[tex]T - 76 = -4[/tex]
[tex]T = 72[/tex]
The two solutions, [tex]T = 72[/tex] and [tex]T = 80[/tex], mean that the temperature of the aquarium water must be between these two values.A similar problem is given at https://brainly.com/question/22532602

A merchant has coffee worth $40 a pound that she wishes to mix
with 60 pounds of coffee worth $90 a pound to get a mixture that
can be sold for $70 a pound. How many pounds of the S40 coffee
should be used?
O 20 pounds
O 40 pounds
100 pounds
O 50 pounds
Answers
Answer:
Step-by-step explanation:
let x = the number of pounds of cheaper coffee.
Since the merchant is mixing this with more expensive coffee, then
x + 60 = the number of pounds of medium priced mixed coffee.
The equation is gotten from this
+ =
(x)($40) + (60)($90) = (x + 60)($70) or
40x + 5400 = 70(x + 60)
Solve that equation and get x = 40
Answer: 40 pounds of $40 coffee.

Write the equation of a line in slope-intercept form, y = mx + b, between the following
points: (2, 5) and (-4,-4).
Answers
Answer:
[tex]y = \frac{3}{2} x + 2[/tex]
Step-by-step explanation:
In the slope-intercept form y= mx +b, m is the slope and b is the y- intercept.
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} } [/tex]
Using the formula above,
[tex]slope = \frac{5 - ( - 4)}{2 - ( - 4)} [/tex]
[tex]m = \frac{5 + 4}{2 + 4} [/tex]
[tex]m = \frac{9}{6} [/tex]
[tex]m = \frac{3}{2} [/tex]
Substitute the value of m into the equation:
[tex]y = \frac{3}{2} x + b[/tex]
To find the value of b, substitute a pair of coordinates into the equation.
When x= 2, y= 5,
[tex]5 = \frac{3}{2} (2) + b[/tex]
5= 3 +b
b= 5 -3
b= 2
Thus, the equation of the line is [tex]y = \frac{3}{2} x + 2[/tex].
The sum of three consecutive odd integers is 87. Which equation could you use to find the three
integers and what is the largest integer?
O 3k + 4 = 87
The largest integer is 31
O k + (k + 2) + (k + 4) = 87
The largest integer is 31
O k + (k + 2) + (k + 4) = 87
The largest integer is 29
O k + (k + 1) + (k + 3) = 87
The largest integer is 31
Answers
Answer:
[tex]k+(k+2)+(k+4)=87[/tex]
The largest integer is 31.
Step-by-step explanation:
Hi there!
Let k be equal to the smallest of the integers.
Let (k+2) be the next odd integer.
Let (k+4) be the final odd integer.
We're given that the sum of these three integers is 87. Construct an equation:
[tex]k+(k+2)+(k+4)=87[/tex]
Combine like terms:
[tex]k+k+2+k+4=87\\3k+6=87\\3k=81\\k=27[/tex]
Therefore, the smallest integer is 27. Because the largest integer is k+4, the largest integer is therefore 31.

a tennis shop sold twenty $100 racquets at an 8% profit and ten $80 bags at a 15% loss. The profit on the combined transaction was
PLEASE HELP. I'LL GIVE THE BRAINLIEST.
Answers
Now to find the profit we can do
20 x 100= 2000
Now
8=x/2000*100
X= 160
And now for loss
10x80=800
Now
15= x/800*100
X=120
Now profit =
160-120 = 40
The profit was only 40
Answer:
$ 40
Step-by-step explanation:
Rackets:
Cost Price (CP) = $ 100
Profit percent = 8%
Profit = 8% * 100 = [tex]\frac{8}{100}*100 = 8[/tex]
Profit for one racket =$8
Profit for 20 rackets = 8*20 = $ 160
Bags:
CP = $ 80
Loss percent = 15%
[tex]Loss = \frac{15}{100}*80=12[/tex]
Loss for 10 bags = 12 * 10 = $ 120
The profit in the combined transaction = 160 - 120 = $ 40

Points X, Y, and Z are collinear, with Y in between X and Z. If XY = 5x, YZ = 2x + 7, and XZ = 56, find x.x = 7
Answers
When two or more points are on a straight path, then they are collinear. So that in the given question, the value of x is 7.
Two or more points are said to be collinear if and only if they fall on a straight line. Thus, the points can be joined by a single straight line.
From the given question, it can be observed that;
XZ = XY + YZ
But given the following:
XY = 5x, YZ = 2x + 7, and XZ = 56
Then,
56 = 5x + (2x + 7)
= 5x + 2x + 7
56 = 7x + 7
collect like terms to have
56 - 7 = 7x
49 = 7x
x = [tex]\frac{49}{7}[/tex]
= 7
x = 7
Therefore, the value of x is 7.
