Answer:
(3x + 4)/(2 - 6x) = -2/5
=>5(3x + 4) = -2(2 - 6x)
=> 15x + 20 = -4 + 12x
=> 15x -12x = -4 -20
=> 3x = -24
x = -24/3 = -8

Camille's science class is making slime from cornstarch and glue. Camille is helping pass out materials. She gives each student 4 ounces of cornstarch from a 5-pound bucket. If Camille's class has a total of 18 students, how many ounces of cornstarch will she have left?
Answer:
8 ounces
Step-by-step explanation:
16oz/lb
16*5= 80oz of cornstarch in bucket
4oz * 18students = 72oz
80-72= 8 oz remaining
The amount of cornstarch left is 8 ounce.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Each student get = 4 ounce of cornstarch
Total number of student = 18 students
And, Total amount of cornstarch = 5 pound
Here,
Since, Amount of total cornstarch to student = Each student get × Total number of student
⇒ Amount of total cornstarch to student = 4 × 18
⇒ Amount of total cornstarch to student = 72 ounce
Since, 1 pound = 16 ounces
So, We get;
⇒ Total amount of cornstarch = 5 × 16
⇒ Total amount of cornstarch = 80 ounces
Thus, Amount of cornstarch left = 80 - 72
⇒ Amount of cornstarch left = 8 ounces

The triangles are not similar.
What is similarity in triangles?Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.
The Given triangle ZXB and DZN are not similar
Because,
XZ/DZ =XB/DN ≠ ZB /BN
XZ/DZ = 1/2
XB/DN = 1/2
ZB /BN = 1/3

Jamal has two trails. the first trail is 5 1/3 miles long, and the second trail was 1 3/4 times as long as the first trail. how many miles did Jamal walk?
Answer:
The correct answer is Jamal hiked [tex]14\frac{2}{3}[/tex] miles.
Step-by-step explanation:
To solve this math problem, you will need to convert mixed numbered fractions, into improper fractions.
To do that, you will need to multiply the whole number with the denominator (Ex: 5 × 3 = 15), then when you receive the answer, add the answer with the numerator (Ex: 15 + 1 = 16), finally, you should receive a new answer, and to finalize the improper fraction, you always need to keep the denominator the same (Ex: The denominator is 3 so use the new answer as a numerator replacement. [tex]\frac{16}{3}[/tex])
--
After you have converted all the mixed numbers into improper fractions in the math problem, you are then able to use multiplication.
--
But first we have to calculate how long the second trail was.
[tex]\frac{7}{4} *\frac{16}{3} =7*\frac{4}{3} =\frac{28}{3} =9\frac{1}{3}[/tex] miles. Then, convert the mixed number into improper. ([tex]\frac{28}{3}[/tex])
--
Now add the number of miles of both trails.
[tex]\frac{16}{3} +\frac{28}{3} =\frac{44}{3} =14\frac{2}{3}[/tex]
With the result as: [tex]14\frac{2}{3}[/tex]

Lin is paid $86 for 4 hours of work how much would she be paid at this rate for 9 hours of work?
Answer:
173.5
Step-by-step explanation:
The answer is 173.5
To solve this type of equation we first have to find the unit rate, in this case, the unit rate is dollars every hour, in order to find this we have to divide 86 by 4 as shown below
[tex]86/4=21.5[/tex]
Therefore the unit rate is 21.5$ every hour so in order to find how much money she was paid after 9 hours we have to multiply 21.5 by 9, which is shown below
[tex]9x21.5=173.5[/tex]
Thus, that is how much money Lin will be paid after 9 hours of work.
