Step-by-step explanation:

Answer:

Alicia is 18years

Quentin is 14years

Rosalyn is 16years

Step-by-step explanation:

Let the age of Alicia be x

Let the age of Quentin be y

Let the age of Rosalyn be z

If the sum of the siblings’ ages, in years, is 48 then;

x+y+z = 48.... 1

If Rosalyn is two years older than Quentin then;

z =y+2 ..... 2

Also if Quentin is four years younger than Alicia then;

y = x-4 ... 3

From 3:

x = y+4 ... 4

Substitute 2 and 4 into 1 to have:

y+4+y+y+2 = 48

3y + 6= 48

3y = 48-6

3y= 42

y = 14

Since x= y+4

x = 14+4

x = 18

Since z = y+2

z = 14+2

z = 16year

This means that;

Alicia is 18years

Quentin is 14years

Rosalyn is 16years

Answer:

maybe B because this answer fits the question more for me

I can't help you because I'm also stuck on this question for mathematics in middle school, and it's hurting my brain just trying to figure it out :[

Answer:

y = -3x - 5

Step-by-step explanation:

-2y = 6x + 10

divide both sides by -2

y = -3x - 5

Choice 2

Step-by-step explanation:

Ask a friend or older sibling, they always have the answer (Not really)

Answer:

3^4x-5=1/27^2x+10

We move all terms to the left:

3^4x-5-(1/27^2x+10)=0

Domain of the equation: 27^2x+10)!=0

x∈R

We get rid of parentheses

3^4x-1/27^2x-10-5=0

We multiply all the terms by the denominator

3^4x*27^2x-10*27^2x-5*27^2x-1=0

Wy multiply elements

81x^6-270x^2-135x^2-1=0

We do not support expression: x^6

Answer:

A is your answer

Step-by-step explanation:

width= 9 cm

length= 5 cm

height= 20cm

formula: 2(lw+lh+hw)

2(5*9+ 5*20+ 20*9)

2(45+ 100+ 180)

2(325)= 650 cm

Answer:

obtuse angles

A TV programme begins at 7:45 p.m. and ends 50 minutes later.At 8:35 pm time it will finish.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

It is given that a TV programme begins at 7:45 p.m. and ends 50 minutes later.

Addition is one of the fundamental mathematical operations we utilize on a daily basis. We employ addition of numbers in a variety of contexts. Working with time or money, such as adding up bills and receipts, is one of the most frequent daily uses for adding numbers.

We have to apply the addition operation by splittiong the time as,

=7:45 p.m + 50 minute

=7:45 p.m + 15 minute + 35 minute

=8:00 pm + 35 minute

=8:35 pm

Thus, a TV programme begins at 7:45 p.m. and ends 50 minutes later.At 8:35 pm time it will finish.

Answer:

[tex]\mathtt{\huge\star{\pink{\underline{ 12,\: 10,\: 8,\: 6,\:4,\:2,\:-1,/:-3........ infinite }}}}\huge\star[/tex]

Answer:

Area shaded = 60 [tex]cm^{2}[/tex].

Step-by-step explanation:

From the given diagram,

Area shaded = Area of the trapezoid EBCD

Given that: AE = [tex]\frac{1}{3}[/tex]AB

                        =  [tex]\frac{1}{3}[/tex] x 12    (∵ AB = CD = 12 cm)

                        = 4 cm

                  AE = 4 cm,

Thus,

EB = (12 - 4) cm

    = 8 cm

EB = 8 cm

Area shaded = [tex]\frac{1}{2}[/tex] (EB + CD) x AD

                     =  [tex]\frac{1}{2}[/tex] (8 + 12) x 6

                     = (20) x 3

                     = 60

Area shaded = 60 [tex]cm^{2}[/tex]

Answer:

All real numbers

Step-by-step explanation:

3(5x - 4) < 15x

~Distribute left side

15x - 12 < 15x

~Subtract 15x to both sides

-12 < 0

Best of Luck!

Given data

We are given that the initial distance walked is  4 miles

Also, the rate/ speed with which you are currently walking is 3 miles per hour

let the time taken be hours

and let the total distance be y

Step two:

We want to write an expression for the total distance

The total distance is given as
