I’ll give brainliest! Please it’s already missing

<h2>Answer:-</h2>

$\pink{\bigstar}$ Amount of apple juice Will added $\large\leadsto\boxed{\tt\purple{1 \frac{5}{12}}}$

<h3>• Given:-</h3>

Will puts 1/4 cup of grape juice in a cup.
He added apple juice and then he had 1⅔ cup of juice in the cup.

How much apple juice Will added to the cup?

<h3>• Solution:-</h3>

➪ Amount of grape juice Will added = 1/4

➪ Amount of juice in total after adding the apple juice = 1⅔

Therefore, it is clear that the amount of apple juice Will added to the cup will be the difference in total amount of juice and amount of grape juice.

Hence,

➪ $\sf 1 \frac{2}{3} - \dfrac{1}{4}$

➪ $\sf \dfrac{5}{3} - \dfrac{1}{4}$

• Taking an L.CM:-

➪ $\sf \dfrac{20 - 3}{12}$

➪ $\sf \dfrac{17}{12}$

➪ $\large{\bold\red{1 \frac{5}{12}}}$

Therefore, the amount of apple juice added is $\large{\bold 1 \frac{5}{12}}$

The area of trapezium is 352 cm2. The distance between the parallel

Naddik [55]

Answer:

18cm

Step-by-step explanation:

Area of Trapezium = 1/2(a + b) h

Where:

A = 352cm^2

h = distance between parallel sides = 16cm

a = 25cm

b = ?

352 = 1/2 (25 + b) 16

352 = (25 + b) 8

352 = 200 + 8b

352 - 200 = 8b

152 = 8b

152/8 = b

19= b

→b = 19cm

The other parallel side is 19cm.

Prove that if d|m and d|n, then d|(m+n)

Mila [183]

$d\mid m$ means to say there is some $k_1$ such that $m=dk_1$ . Similarly, $d\mid n$ is equivalent to saying there exists $k_2[/te]x such that [tex]n=dk_2$ .

Now, $m+n=dk_1+dk_2=d(k_1+k_2)=dk_3$ , i.e. there is some $k_3$ such that $m+n$ is a multiple of $d$ , i.e. $d\mid(m+n)$ .

In the pair of equations bx-6y=18 and 2x-3y=9, b is a whole number. The system of two equations has infinitely many solutions. W

statuscvo [17]

To have infinite solutions, they have to be th esame line

match waht we do know

bx-6y=18
the coefient of y is -6
other one is
2x-3y=9
-3 times 2=-6
times 2nd equation by 2
4x-6y=18
bx-6y=18
b=4
