Answer:
y = -3.75
Step-by-step explanation:
Solving equations with decimal fractions is done the same way as with numbers in any other form. Use your skill with decimal number arithmetic.
0.10(y -7) +0.02y = 0.20y -0.4
0.10y -0.70 +0.02y = 0.20y -0.40
-0.30 +0.12y = 0.20y . . . . . . . . add 0.40 and collect terms
-0.30 = 0.08y . . . . . . . . . . . . . . subtract 0.12y
-0.30/0.08 = y = -3.75 . . . . . . .divide by the coefficient of y

Members of a soccer team raised $2158 to go to a tournament. They rented a bus for $1130.50 and budgeted $68.50 per player for meals. Write and solve an equation which can be used to determine xx, the number of players the team can bring to the tournament.
Answer: 15
Step-by-step explanation:
Let x = the number of players the team can bring to the tournament.
Given: Soccer team raised $2158 for tournament.
Bus rent = $1130.50 and budget per player for meals = $68.50
Total cost of tournament = Bus rent + (budget per player for meals) ( number of players the team)
[tex]2158=1130.50+68.50x\\\\\Rightarrow\ 68.50x=2158-1130.50\\\\\Rightarrow\ 68.50x=1027.5\\\\\Rightarrow\ x=\dfrac{1027.5}{68.5}\\\\\Rightarrow\ x=15[/tex]
Hence, the number of players the team can bring to the tournament = 15

Answer: x = 41
Step-by-step explanation:
The side of the hypothenuse will be gotten when we add the square of the other two lengths and then find the square root. Thus will be:
x² = ✓(40² + 9²)
x² = ✓1600 + 81
x² = ✓1681
x = 41

Which choice is the solution set for the inequality below , sqrt of x > 11 , I had put x>121 n got it wrong not sure what I need to do
Answer: Option B, x ≥ 121
Step-by-step explanation:
We start with the inequality:
√x ≥ 11.
First, we can square each side of the inequality, to get:
(√x)^2 ≥ 11^2
And we know that:
√(x^2) = (√x)^2 = x
Then:
x ≥ 11^2
x ≥ 121
So we only need to have x equal or larger than 121.
The correct option is B.

Using ƒ(x) = 2x + 7 and g(x) = x − 3, find ƒ(g(x)).
Answer:
We get [tex]\mathbf{f(g(x))=2x+1}[/tex]
Option A is correct answer.
Step-by-step explanation:
We are given:
[tex]f(x) = 2x + 7 \\g(x) = x - 3[/tex]
We need to find f(g(x))
f(g(x)) can be found by putting x in f(x) equal to g(x)
Now, finding f(g(x))
[tex]f(x)=2x+7\\Put\:x=x-3\\f(g(x))=2(x-3)+7\\f(g(x))=2x-6+7\\f(g(x))=2x+1[/tex]
So, we get [tex]\mathbf{f(g(x))=2x+1}[/tex]

Some female butterflies lay their eggs in clusters. If one kind of butterfly lays 12 eggs at a time and another kind lays 18 eggs at a time, how many eggs would 8 of each kind of butterfly lay? a 96 eggs b 144 eggs c 240 eggs d 200 eggs
Answer: 240 eggs
Step-by-step explanation:
The first kind of butterfly lays 12 eggs at a time. If there were 8 of them they would lay:
= 12 * 8
= 96 eggs
The second kind lays 18 eggs a time. 8 of them would lay:
= 18 * 8
= 144 eggs
Total number of eggs is:
= 96 + 144
= 240 eggs
