2. Lilly and Laura pooled their money to purchase
their brother, Liam, a video game for his birthday.
The video game cost a total of $45. If Laura was
only able to contribute 2/3 of what Lilly did, how
much did Laura put toward the present?
F. $18
G. $21
H. $24
J. $27
K. $30
(Retyped)
Laura put $18 toward the present. Therefore, the correct answer is F. $18. Let's use variables to represent the amounts that Lilly and Laura contributed.
Let L be the amount Lilly contributed and 2/3L be the amount Laura contributed.
According to the information given:
L + 2/3L = $45
To solve for L, combine the terms with L:
1L + 2/3L = $45
To combine the fractions, find a common denominator:
(3/3)L + 2/3L = $45
Now, the fractions have a common denominator:
(5/3)L = $45
To isolate L, divide both sides by 5/3:
L = $45 / (5/3)
To divide by a fraction, multiply by its reciprocal:
L = $45 * (3/5)
L = $9 * 3
L = $27
So, Lilly contributed $27.
Now, to find how much Laura contributed:
Laura's contribution = 2/3L = 2/3 * $27 = $18

A submarine travels 8.3 km due North from its base and then turns and travels due West for 13.9 km.
How far away is the submarine from its base?
Give your answer rounded to 1 DP
Answer:
He is 5.6 km away
Step-by-step explanation:
he starts traveling away from base and is 8.3 km away to start with
then he turns west and travels 13.9 km away
what this mean is that you have to subtract the distance he turned from the distance he started off with
ex: 13.9 - 8.3 = 5.9
to get your answer of how far away he is from the base

The equation 20x2=4kx−13kx2+2 where k is a constant, has no real roots. It can be shown that k satisfies the inequality 2k2+13k+20<0.
Find the set of possible values for k.
Answer:
16k with the little 2 by the k so like 16k2-4(2)(-5k)
Step-by-step explanation:
ANSWER IS -5/2<K<0.
The set of possible values for k is -4<k<-5/2.
The given equation 20x²=4kx-13kx²+2 and the inequality is 2k²+13k+20<0.
What are the roots?For a given quadratic equation ax² + bx + c = 0, the values of x that satisfy the equation are known as its roots. i.e., they are the values of the variable (x) which satisfies the equation. The roots of a quadratic function are the x-coordinates of the x-intercepts of the function.
The given equation has no real roots.
4kx-13kx²+2-20x²=0
⇒ 4kx-x²(13k+20)+2 = 0
If the discriminant of a quadratic function is less than zero, that function has no real roots.
Compare 4kx-x²(13k+20)+2=0 with ax² + bx + c = 0, we get a= - (13k+20), b=4k and c = 2.
So, b²-4ac<0
(4k)²-4(-(13k+20))(2)<0
⇒ 16k²+8(13k+20)<0
⇒ 8(2k²+13k+20)<0
⇒ 2k²+13k+20<0
Using splitting middle term method, we get
2k²+8k+5k+20<0
⇒ 2k(k+4)+5(k+4)<0
⇒ (k+4)(2k+5)<0
⇒ -4<k<-5/2
Therefore, the set of possible values for k is -4<k<-5/2.

→ 9(x-6)+41 = 75. Transposing the like terms.
→ 9(x-6) = 75 - 41 Performing subtraction of the term in RHS
→ 9(x-6) = 34 Performing multiplication in LHS.
→ 9x - 54 = 34 Distributive property
→ 9x = 34 + 54 Performing addition of the term in RHS.
→ 9x = 88. Now, transpose 9 from LHS to RHS , it's arthmetic operator will get changed.

Find the probability of taking a vacation in July.
This is literally all i have to go with can someone help pls.
Answer:
1/2
Step-by-step explanation:
Consider the linear function f(x)=4x -5.
Find f(3), f(0), f(-2).
Answer: f(3)= 7, f(0)= -5, f(-2)= -13
Step-by-step explanation:
Substitute and plug in.
For f(3), we plug in 3 for x in the equation.
So, 4(3)-5, which is just 12-5, which is 7
We do the same for f(0),
4(0)-5, which is 0-5, which is -5
Once again for f(-2),
4(-2)-5, which is -8-5, which is -13

Step-by-step explanation:
5) angle 5 = 69°
than, angle 10 = 69° ( alternate interior angle )
6) angle 6 = 115° ( alternate interior angle )
7) angle 7 = 118° ( alternate interior angle )
8) angle 11 = angle 4 - 180
