c) When x=11 , put in equation 11+(11+4)=11+15=26---> T
d) T=40 x+(x+4)=40
=> 2x+4 = 40
=> 2x. = 36

What is the y intercept of 60x+55y=660 [with work shown]
Answer:
(11, 0)
Step-by-step explanation:
to find the y intercept, set y to 0.
60x + 55y = 660
60x + 55 * 0 = 660
60x = 660
60x/60 = 660/60
x = 11
y intercept is (11, 0)
Marcus and Lara each have the same number of songs on their ipods. Marcus has 10x + 8 songs and Lara has
15x - 92 songs. What is x?
Answer:
The value of x is 20.
Step-by-step explanation:
Given that
Number of songs Marcus has = 10x+8
Number of songs Lara has = 15x-92
It is also given that they have the same number of songs that means both the expressions should be equal.
Putting both equal
[tex]10x+8 = 15x-92[/tex]
This is a linear equation in one variable which can be solved using properties of equality
Subtracting 10 from both sides
[tex]10x+8-10x = 15x-92-10x\\8 = 5x-92[/tex]
Adding 92 on both sides
[tex]8+92 = 5x-92+92\\100 = 5x[/tex]
Dividing both sides by 5
[tex]\frac{5x}{5} = \frac{100}{5}\\x = 20[/tex]
Hence,
The value of x is 20.
Bryan spent 14 minutes on the phone while routing 7 phone calls. How many phone cells does Bryan have to route to spend a total of 16 minutes on the phone? Solve using unit rates.
Answer:
8 phone cells
Step-by-step explanation:
We are told that he spent 14 minutes on the phone while routing 7 phone calls.
Now, we want to find the number of phone cells he will route for a total of 16 minutes.
Thus, by proportion using unit rates;. Number of minutes spent pet phone cell = 14 minutes ÷ 7 phone calls = 2 minutes per phone cell
Therefore, for 16 minutes, number of phone cells will be;
16 minutes ÷ 2 minutes per phone cell = 8 phone cells

Which of the following could NOT be the lengths of the sides of a triangle?
A.5 in, 5 in, 5 in
B. 10 cm, 15 cm, 20 cm
C. 3 in, 4 in, 5 in
D. 8 ft, 15 ft, 5 ft
Given:
Sides of triangles in the options.
To find:
Which could NOT be the lengths of the sides of a triangle.
Solution:
Condition for triangle:
Sum of two smaller sides of a triangle must be greater than the longest side.
In option A,
[tex]5+5=10>5[/tex]
Sides 5 in, 5 in, 5 in are the lengths of the sides of a triangle.
In option B,
[tex]10+15=25>20[/tex]
Sides 10 cm, 15 cm, 20 cm are the lengths of the sides of a triangle.
In option C,
[tex]3+4=7>5[/tex]
Sides 3 in, 4 in, 5 in are the lengths of the sides of a triangle.
In option D,
[tex]8+5=13<15[/tex]
Since, the sum of two smaller sides is less than the longest side, therefore the sides 8 ft, 15 ft, 5 ft are not the lengths of the sides of a triangle.
Therefore, the correct option is D.

Answer: 20 : 3 : 12
Step-by-step explanation:
For every 1 litre, 150 ml of sucrose and 600ml of saline solution is needed.
1litre = 1,000 ml
Water = 1,000 ml

John takes out a loan for $ 12 , 000 at a simple interest rate of 4.5 % to be paid back in 36 monthly installments. What is the amount of the monthly payments?
Answer: $378.33
Step-by-step explanation:
First we calculate the Simple interest which will be:
= 12000 × 4.5% × 3
= $1620
Total amount to be paid = $12000 + $1620 = $13620
Since there are 36 monthly installments, the amount of the monthly payments would be:
= $13620 / 36
= $378.33

what fraction is equivalent to 4 12?
Answer:
1/3
Step-by-step explanation:
1/3, 2/6, 3/9, 4/12.
are equivalent fractions. Equivalent fraction of a given fraction is got by multiplying or dividing its numerator and denominator by the same whole number.
The given fraction 4/12 is equivalent to 1/3 which means that both fractions represent the same value.
To find a fraction equivalent to 4/12, we need to simplify it by reducing the numerator and denominator to their lowest terms.
In this case, the GCD of 4 and 12 is 4. When we divide both the numerator and denominator by 4, we get:
4/12 = (4 ÷ 4) / (12 ÷ 4)
= 1/3
Therefore, 4/12 is equivalent to 1/3.
This means that both fractions represent the same value, but the fraction 1/3 is in its simplest form, where the numerator and denominator have no common factors other than 1.

What is the slope of a line perpendicular to the line whose equation is 2x+12y=-1922x+12y=−192. Fully reduce your answer.
Answer:
The slope of the perpendicular line m =6
Step-by-step explanation:
Step(i):-
Given that the equation of the straight line
2x + 12y =-192
⇒ 12 y = -192 -2x
[tex]y = \frac{-2x}{12}- \frac{192}{12}[/tex]
[tex]y = \frac{-x}{6} - 16[/tex]
y = m x +C
The slope of the given line[tex]m = \frac{-1}{6}[/tex]
Step(ii):-
The slope of the perpendicular line
[tex]\frac{-1}{m}[/tex]
= [tex]\frac{-1}{\frac{-1}{6} }[/tex]
