Explanation

 24 is split into two parts such that 7 times the first plus 5 times the second is 146.

Let the first part be 

x, then the second is 

7x+5(24−x)=146

7x+120−5x=146

2x=26⇒x=13

"They will be playing cricket at that time."

• The phrase "at that time" suggests a future point in time.

• To express an action that will be happening at a specific time in the future, we use the future continuous tense:
  → "will be" + verb-ing

Explanation

In the 2018 general elections, the Election Commission of Pakistan (ECP) declared 20,789 polling stations as sensitive out of a total of 85,307 established across the country. ​

These sensitive polling stations were distributed across the provinces as follows:​

• Khyber Pakhtunkhwa: 7,386
• Sindh: 5,776
• Punjab: 5,686
• Balochistan: 1,768
• Islamabad Capital Territory: 173​

Explanation

Let angle = $x$
Complement = $90 - x$, Supplement = $180 - x$
Given:

$$6(90 - x) = 2(180 - x) - 12 \ 540 - 6x = 360 - 2x - 12 \ 540 - 6x = 348 - 2x \ 192 = 4x Rightarrow x = 48$$

$$540-6x=360-2x-12$$

$$540-6x=348-2x$$

$$192=4x\Rightarrow x=48$$

Explanation

 "I would die rather than ask a loan."

After "rather than", we use the base form of the verb (bare infinitive)

When it follows another verb in the same clause, especially after modal verbs like would.

So:

• "I would die rather than ask a loan" (Correct)

• "To ask"  (Infinitive form is incorrect here)

• "Have asked"  (Perfect form is not suitable)

Explanation

If $a + 3b = 6$ and $ab=3$, then the value of $a^2 + 9b^2$ is:

We are given:

a+3b=6(1),ab=3(2)

$$$$a+3b=6(1),ab=3(2)

Now square equation (1):

$$(a + 3b)^2 = 6^2 = 36 Rightarrow a^2 + 9b^2 + 6ab = 36$$

Use $ab = 3$

$$a^2 + 9b^2 + 6(3) = 36 Rightarrow a^2 + 9b^2 + 18 = 36 Rightarrow a^2 + 9b^2 = 18$$

Explanation

Step-by-step:

$$frac{31 times 3}{100} = frac{93}{100}, quad frac{7}{5} = frac{140}{100}, quad 20 = frac{2000}{100}$$

Add all:

93+140+2000​/100=2233​/100=22.33

Explanation

An array formula is a formula that can perform multiple calculations on one or more of the items in an array.

We can think of an array as a row of values, a column of values, or a combination of rows and columns of values.

Array formulas can return either multiple results or a single result.
