\huge \boxed{\mathfrak{Question} \downarrow}

  • Evaluate the expression, \boxed{\underline{\bf \: 5^{2}}}

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

  • 5² is nothing but ⇨ <u>5 × 5 = 25.</u>
  • Here the 2 displayed above is the exponent or power of 5. So, we have to square 5. This means that we have to multiply 5 by itself & the product formed <u>(25)</u> is the correct answer.

. Dillion deposits $150 into his account. One week later, he withdraws $26. Write an addition expression to represent this situa
Lina20 [59]

Answer:

Expression = x + 150 +(- 26)

$124 higher

Step-by-step explanation:

Given

Deposit = \$150

Withdrawal = \$26

Required

Represent the situation

Determine how much higher or lower is the remaining amount

Let the initial amount in his account be represented with x

When he deposited, the balance becomes

Balance = x + 150

When he withdrew, the balance becomes

Balance = x + 150 + (-26)

Hence, the algebraic expression is

Expression = x + 150 +(- 26)

Calculating how much higher or lower

Balance = x + 150 + (-26)

Open bracket

Balance = x + 150 -26

Balance = x + 124

Recall that the initial amount in the account is x

The difference between the balance and the x is as follows

Difference = x + 124 - x

Difference = \$124

<em>Hence, the account has a higher of $124 after both transactions</em>

Marsha spends 150 minutes a night doing homework.
kodGreya [7K]

Answer:

70%

Step-by-step explanation:

Maths homework takes 1/6×150mins

=150/6=25 mins

science homework takes 20/100×150

=3000/100

=30mins

Language Arts homework uses 1/3×150

=150/3

=50 mins

percent of time left for Marsha's social studies homework=total time used / original time

=(25+30+50)mins

=105mins/150mins×100%

=0.7×100

=70%
