Divide £180 in the ratio 3:7

Answers

Answer:3+7=10

180*3/10=54

180*7/10=126

126+54=180

54&126

Answer:

One = 3x = 3 x 18 = 54

Second = 7x = 7 x 18 = 126

Step-by-step explanation:

3x+7x = 180

10x = 180

x = 180/10 = 18

One = 3x = 3 x 18 = 54

Second = 7x = 7 x 18 = 126

MATH HELP!!! MARKING BRAILIESTT

Answers

Answer:

y = 3x - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x - 12 ← is in slope- intercept form

with slope m = 3

Parallel lines have equal slopes , then

y = 3x + c ← is the partial equation

To find c substitute (1, - 2 ) into the partial equation

- 2 = 3 + c ⇒ c = - 2 - 3 = - 5

y = 3x - 5 ← equation of parallel line

Is the following function LINEAR or NONLINEAR?
y = 8x+ 5
linear
nonlinear

Answers

Answer:

Linear

Step-by-step explanation:

Linear it forms a straight line when it graphed. It also has a slope and a constant.

your answer is linear



A linear equation is an equation of a straight line, which means that the degree of a linear equation must be
0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 1.

Does the equation represent a linear or nonlinear function?

y=x2+3

Answers

Answer:

Nonlinear function.

Step-by-step explanation:

If the x2 is supposed to mean x², then the function is quadratic, not linear.

Answer: Nonlinear function.

Step-by-step explanation:

the variables do not have powers more than 1,

variables do not occur in the denominator of a fraction.

different variables do not appear in the same term

In this case, there is a term in x2

so the function is not linear.

It is a parabola.

The number of kilograms of water in a person's body is directly proportional to the
person's mass. A person with a mass of 100 kg contains 66kg of water. How many
kilograms of water are in a person with a mass of 150 kg?

please help asap !!!

Answers

For kgP equals kg of person
KgW equals kg of water

Just use ratios to get the answers and solve for X.

100kgP/66kgW=150kgP/X
X= 150 kgP * 66 kgW / 100 kgP
X= 99 kgW

So 99 kg of water in a 150 kg person

2-(3x+5)=5-2x

i have too answers but need the right one lol​

Answers

Answer:

x = -8

Step-by-step explanation:

2 - (3x + 5) = 5 - 2x

Subtract 2 from each side.

-(3x + 5) = 3 - 2x

Apply the negative sign in front of the parentheses.

-3x - 5 = 3 - 2x

Add 5 to both sides.

-3x = 8 - 2x

Add 2x to both sides.

-x = 8

We can't have a negative x value, so we'll need to multiply each side by -1.

x = -8

Hopefully, this helped and wasn't too confusing!

Answer:

Solution given;

2-(3x+5)=5-2x

2-3x-5=5-2x

-3-5=3x-2x

x=-8 is your answer

answer is 3 11/12

Step-by-step explanation:

1 4/6 =10/6

2 1/4=9/4

when adding fractions that are do not share a common denominatour you have to find a common multiple

which in this case is 12

so 9/4 timesed the top and the bottom by 3 gives you 27/12

and 10/6 timesed the top and bottom by 2 gives you 20/12 and then you add the the nominators which is 20+27 which then gives you 47/12 and then to change it back to mixed fraction you will get 3 (wholes) and 11/12 (fraction)
