sladkih [1.3K]

Step-by-step explanation:

let,the sum of the ages of chukwu & Caroline be X & Y.

now,

X+y=45

X-y=3

(+) (+) (-)

__________

2x=42

or,X=42/2

or,X=21

putting the value of X,

X+y=45

or, 21+y=45

or,y=45-21

or,y=24

therefore,X=21

y=24

If QR = 18, RS = x -11, and QS = 2x - 11, what is QS?

monitta

Answer:

QS =25

Step-by-step explanation:

QR + RS = QS

18 + (x-11) =2x-11

7 +x =2x -11

18=x

Plug in x

2(18) -11

36-11

QS=25

18 + (18-11) = 2(18)- 11

18+ 7 = 36 -11

25= 25

True

27 1/5 over 4/5 as a unit rate

REY [17]

Answer:

$\frac{34}{1}$ or $34$

Step-by-step explanation:

we know that

To find the unit rate divide 27 1/5 by 4/5

but first

Convert mixed number to an improper fraction

$27\frac{1}{5}=27+\frac{1}{5}=\frac{27*5+1}{5} =\frac{136}{5}$

$\frac{136}{5}:\frac{4}{5}=\frac{136}{4}=\frac{34}{1}$

Can someone help me with this answer I’m on a test and it’s almost due

Brrunno [24]

16.5 / p = 11 / 18

p = 16.5 × 18 / 11

p = ( 16.5 / 11 ) × 18

p = 1.5 × 18

p = 27

6. m A = 8x - 2, m B = 2x - 8, and m2 C = 94 - 4x. List the sides of A ABC in order from shortest to

Oduvanchick [21]

Given:

In triangle ABC, m∠A=(8x-2)°, m∠B=(2x-8)° and m∠C=(94-4x)°.

To find:

The sides of the triangle ABC in order from shortest to longest.

Solution:

In triangle ABC,

$m\angle A+m\angle B+m\angle C=180^\circ$ (Angle sum property)

$(8x-2)^\circ+(2x-8)^\circ+(94-4x)^\circ=180^\circ$

$(6x+84)^\circ=180^\circ$

$6x+84=180$

$6x=180-84$

$6x=96$

Divide both sides by 6.

$x=\dfrac{96}{6}$

$x=16$

Now,

$m\angle A=(8(16)-2)^\circ$

$m\angle A=(128-2)^\circ$

$m\angle A=126^\circ$

Similarly,

$m\angle B=(2(16)-8)^\circ$

$m\angle B=(32-8)^\circ$

$m\angle B=24^\circ$

And,

$m\angle C=(94-4(16))^\circ$

$m\angle C=(94-64)^\circ$

$m\angle C=30^\circ$

In a triangle the smaller angle has shorter opposite side and larger angle has longer opposite side.

$24^\circ$

$m\angle B$

$AC$

List the sides of triangle ABC in order from shortest to longest is AC:AB:BC.

Therefore, the correct option is A.
