Linda and Philip share £54 in the ratio 4:5. Find how much money each of them will recieve
Answer:
Linda has £24 and Philip has £30.
Step-by-step explanation:
Denote a variable to the amount of money Linda and Philip have:
Money Linda has = L
Money Philip has = P
L + P = 54
There is a ratio of 4:5 so for every £4 Linda has, Philip will have £5. When adding both values, 4+5, you get 9.
Divide the total amount of money by the sum of the ratio numbers so 54/9 which gives 6.
Multiply the number you get from the division by their respective ratios.
Linda = 6 * 4 = 24
Philip = 6 * 5 = 30
Add both numbers if you want to make sure the answer is correct.

Given:
The system of equation is
[tex]y-8=-\dfrac{1}{3}x-4[/tex]
[tex]y=-\dfrac{1}{3}x-4[/tex]
To find:
The solution of given system of equations.
Solution:
The slope intercept form of a line is
[tex]y=mx+b[/tex]
Where, m is slope and b is y-intercept.
Write the given equation in slope intercept form.
The first equation is
[tex]y-8=-\dfrac{1}{3}x-4[/tex]
[tex]y=-\dfrac{1}{3}x-4+8[/tex]
[tex]y=-\dfrac{1}{3}x+4[/tex] ...(i)
Here, slope is [tex]-\dfrac{1}{3}[/tex] and y-intercept is 4.
The second equation is
[tex]y=-\dfrac{1}{3}x-4[/tex] ...(i)
Here, slope is [tex]-\dfrac{1}{3}[/tex] and y-intercept is -4.
Since the slopes of both lines are same but the y-intercepts are different, therefore the given equations represent parallel lines.
Parallel lines never intersect each other. So, the given system of equation has no solution.
Hence, the correct option is B.
Why is it a problem to find the square root of a negative number, for example √-4?
Answer:
It is not possible because no number times itself can equal a negative number.
Answer:
Taking the square root of a negative number is a problem because this technically does not follow the rules of a square root. A square root is made of a number times itself, and therefore, is impossible to have a negative times a positive to make a negative total (An example would be √4, as the answer can be 2 (because 2 x 2 = 4) or -2 (because -2 x -2 = 4)).
This means that in order to solve √-4, you must use imaginary numbers. This is represented by "i."
For the example of √-4, your answer would be 2i. These imaginary numbers are used whenever you are square rooting a negative number in order to show that it is breaking the real rules of roots.

2y - 5x = 9
4y + 3x = 5
Do not use trial and improvement
Answer:
y = 2, x = -1
Step-by-step explanation:
2y - 5x = 9
2y = 9+5x
y = (9+5x) /2
4y + 3x = 5
4((9+5x) /2) + 3x = 5
13x + 18 = 5
13x = -13
x = -1
y = (9+5x) /2
y = (9+5(-1)) /2
y = 2
Answer:
x = -1, y = 2
Step-by-step explanation:
2y - 5x = 9
4y + 3x = 5
eliminate one of the variables by multiplying the equations and then adding them together.
3(2y - 5x = 9)
5(4y + 3x = 5)
6y - 15x = 27
20y + 15x = 25
26y = 52
y = 2
now input the value of y into one of the original equations to find x.
8 + 3x = 5
8-5 = 3
x = -1

15 lb ≈ ? kg
Answer:
6.82 kg
Step-by-step explanation:
set up a proportion based on 2.2 lbs in 1 kg
2.2/1 = 15/x
cross-multiply:
2.2x = 15
x = 6.82
The value of 15 lb in kg is 6.81 kg.
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.
We know that;
⇒ 1 lb = 0.454 kg
Hence, We get;
⇒ 1 lb = 0.454 kg
⇒ 15 lb = 15 × 0.454 kg
= 6.81 kg
Thus, We get;
⇒ 15 lb = 6.81 kg

there 6 more girls than boys in a class there 44 students in the class in all how many boys are there
Answer: 28 boys and 16 girls
Step-by-step explanation: Divide 44 by 2 to get 22 subtract 22 by 6 to get the girls and add 6 to 22 to get the boys.
Answer:
44% of the students of a class are girls. If the number of girls is 6 less than the number of boys, how many students are there in the class?
let x be the number of boys, so (x - 6) will be number of girls.
total number of students will be boys plus girls : x + (x - 6) = 2x - 6
now 44% are girls which come from formula no. of girls divide by total students into 100: (x - 6)/(2x-6)*100 = 44
by solving we get x = 28 (where x is number of boys)
now x - 6 = 28–6 = 22 (number of girls)
add both we get total number of students = 28 + 22 = 50
Answer = 50

Z
W
Y
What is the measure of angle W?
25°
65°
1150
120°
Answer:
115 degrees
Step-by-step explanation:
We know that angle y is 45 degrees and angle z is 70 degrees so to find x, you do 180-45-70 to get 65 degrees.
Because W plus X has to equal 180 degrees, 180-65=115, so the answer is 115 degrees
Answer:
choice 3) W = 115 degrees
Step-by-step explanation:
all triangle interior angles add up to 180 degrees
180 = 45 + 70 + X
X = 65 degrees
Angle W is supplemental to angle X (angle W and angle X add up to 180 degrees.)
W = 180 - 65 = 115 degrees
