Answer:

It not necessary that every time the sum of two five digit number is a six digit number.

Step-by-step explanation:

We are given the statement that sum of two five digit numbers is always a six digit number.

We have to give a counter example to show that the given statement is false.

It not necessary that every time the sum of two five digit number is a six digit number.

Example:

10,000 + 30,000 = 40,000

13,245 + 74,632 = 87,877

56463 + 26230 = 82693

50,000 + 50,000 = 1,00,000

Find the value of x needed to make the equation below true. -4(1.5x-5)+4x=26
VLD [36.1K]

━━━━━━━☆☆━━━━━━━

▹ Answer

<em>x = -3</em>

▹ Step-by-Step Explanation

-4(1.5x - 5) + 4x = 26

-6x + 20 + 4x = 26

-2x + 20 = 26

-2x = 26 - 20

-2x = 6

x = -3

simplify the following expression: (x+7/4x) + (5/x-8) I also attached a photo of the problem if you get confused on how I typed
Gnoma [55]

Answer:

\frac{x^{2}  + 19x - 56}{4 {x}^{2}   - 32x}

Step-by-step explanation:

Start by making the denominators of both fraction the same. This can be done by multiplying one fraction's denominator by the other.

After simplifying and combining the two fractions together, check if the numerator can be factorised such that there is a common factor in the denominator and numerator. In this case, the numerator cannot be factorised.

Lastly, expand the denominator.

\frac{x + 7}{4x}  +  \frac{5}{x - 8}

=  \frac{(x + 7)(x - 8)}{4x(x - 8)}  +  \frac{5(4x)}{4x(x - 8)}

=  \frac{x(x) + x( - 8) + 7(x) + 7( - 8) + 20x}{4x(x - 8)}

=  \frac{ {x}^{2} - 8x + 7x - 56 + 20x }{4x(x - 8)}

=  \frac{ {x}^{2}  + 19x - 56}{4x(x - 8)}

=  \frac{ {x}^{2}  + 19x - 56}{4 {x}^{2}  -  32x}

A rancher uses a bucket that holds 15,000 milliliters of water to fill a water trough for her horse. The trough holds 2.7 x 10^5
klasskru [66]

Step-by-step explanation:

the volume of the bucket is

15,000 = 1.5 × 10⁴ ml

the trough holds

2.7 × 10⁵ ml

by calculating how often the volume of the bucket fits into the volume of the trough, we will know how many buckets of water are needed :

2.7 × 10⁵ / (1.5 × 10⁴) = 2.7/1.5 × 10⁵/10⁴ = 2.7/1.5 × 10¹ =

= 27/1.5 = 18

the rancher needs 18 buckets of water to fill the trough.
