2. Solve:
у = 3х
x = -2y + 70
Answer: (10,30)
Step-by-step explanation:
y = 3x
x = -2y + 70
Solve by using the substitution method. Substitute the value for x into the first equation and solve for y.
y = 3(-2y + 70) Multiply it out
y = -6y + 210 Add 6y to both sides
+6y +6y
7y = 210
y = 30
Since y is equal to 30, input the value for y into the equation and solve for x.
30 = 3x Divide both sides by 3
x = 10

[tex] \sqrt[3]{( \frac{1}{8} - x)} = - \frac{1}{2} [/tex]
what is the answer?
∛(1/8 - x) = -1/2
Take the 3rd power of both sides and solve:
(∛(1/8 - x))³ = (-1/2)³
1/8 - x = -1/8
2/8 = x
x = 1/4

The population of a colony of mosquitoes obeys the law of uninhibited growth. If there are 1000 mosquitoes initially and there are 1500 after 1 day, what is the size of
the colony after 3 days? How long is it until there are 80,000 mosquitoes?
The size of the colony after 3 days is approximately mosquitoes.
Answer:
There are 2,500 misquitos after 3 days and it takes 158 days to reach 80,000 mosquitos.

Maurice has a paper bag with three hard candies: two blueberries and one green apple. Yvonne and Kate ask if they can each have one. Yvonne closes her eyes and picks a candy from the bag, hoping for a blueberry. What are the chances she will pick a blueberry candy?
Answer:
The chances of Yvonne to get a blue berry candy in the two cases are 1 and 1/2 in case 1 and 2/3 in the case 2.
Step-by-step explanation:
Maurice has a paper bag with three hard candies
2 blueberries and 1 green apple
Yvonne and Kate want 1 candy each
It is not mentioned that ether Kate has taken a candy already before Yvonne or not so we will consider both the cases
Case 1
If Kate has picked a candy before Yvonne
If Kate gets an Apple green candy then the probability or Yvonne to get a Blueberry will be = 2/2 = 1 ( as there will 2 blueberry candy left in the bag)If Kate has taken a Blueberry candy then there will be 1 blueberry and 1 apple green candy in the bag so the probability of Yvonne to get a Blueberry candy will be = 1/2Case 2
If Kate has not taken any candy from the bag before Yvonne
Probability that Yvonne will get a blueberry candy will be = 2/3
Therefore the chances of Yvonne to get a blue berry candy in the two cases are 1 and 1/2 in case 1 and 2/3 in the case 2.

In the given figure, ABCD is a trapezium in which AD || BC,
ABC = 90°, AD = 16 cm, AC = 41 cm and BC = 40 cm. Find the
area of the trapezium,
Answer:
252 cm²
Step-by-step explanation:
Find AB:
AB² = 41² - 40²
AB² = 81
AB = √81
AB = 9 cm
Area of the trapezium = ½(a + b) × h
Where,
a = 16 cm
b = 40 cm
h = 9 cm
Area = ½(16 + 40) × 9
Area = ½(56)×9
Area = 252 cm²
4m + 7 = -3m + 49 what does this
Answer: m = 6
Step-by-step explanation:
first, move the terms.
4m + 3m = 49 - 7
then, collect like terms and calculate.
7m = 42
then divide both sides.
m = 6
Answer:
m=42
Step-by-step explanation:
simplifying both sides of the equation then isolating the variable.

Element X is a radioactive isotope such that every 20 years, its mass
decreases by half. Given that the initial mass of a sample of Element X is 410
grams, how long would it be until the mass of the sample reached 270 grams,
to the nearest tenth of a year?
Answer:
12.1
Step-by-step explanation:
y=a(1/2)^t/h
270=410(1/2)^t/20
Divide both sides by 410
0.6585365854 = (1/2)^t/20
Log Both sides
Log(0.6585365854) / Log(1/2)
.6026645024= t/20
20 x .6026645024 = t
12.05329005 to the nearest tenth is 12.1 = t
