Answer:

419

Step-by-step explanation:

Regrouping in subtraction: If we borrow from one group (tens group) and give to another (Once group) so that the operation can be completed, then this process is called regroup.

For example: We need to find the value of 52-39

52=50+2

39=30+9

We can not subtract 9 from 2. So we will borrow 10 from 50 and give to 2.

52=40+12

Now,

52-39=(40+12)-(30+9)

52-39=(40-30)+(12-9)

52-39=(10)+(3)

52-39=13

We need to find the greatest 3 digit number that can subtract from 426 so that we need to regroup.

To use regroup, the once digit must be more that 6. So, maximum value for once place is 9.

Therefore, the greatest 3 digit number that can subtract from 426 by using regroup is 419.

Can someone help geometry is confusing
NikAS [45]

<LMP and <NMP are supplementary angles so sum = 180

<LMP +  <NMP = 180

(-16x + 13) + ( - 20x + 23) = 180

-16x + 13  - 20x + 23 = 180

-36x + 36 = 180

-36x = 144

    x = -4

<LMP = -16x + 13 = -16(-4) + 13 = 77

<NMP = - 20x + 23 = - 20(-4)  + 23 = 103

Answer

<LMP  = 77°

<NMP  = 103°

A picnic basket was marked up 95% from an original cost of $9.57. Last Friday, Rosanne bought the picnic basket and paid an addi
Montano1993 [528]

Answer:

$20.15

Step-by-step explanation:

Given data

Original cost =  $9.57

Markup= 95%

Let us find the new cost of the basket

=95/100*9.57

=0.95*9.57

=$9.0915

Hence the cost of the basket is

= 9.57+9.0915

=18.66

Also, the sales tax is 8%

=8/100*18.66

=0.08*18.66

=1.4928

Therefore, the total amount to be paid is

=18.66+1.4928

=$20.15

How do I find the slope, domain, range and y intercept of y=-2x
Natasha2012 [34]

Slope is defined as the rate of change, in this case the change in y with respect to x. In standard form for a binomial linear equation, y = mx + b. The constants m and b are the slope and intercept, respectively. For your equation, the slope is -2 and the intercept is 0. The domain (possible values of x) for this graph is (-∞, ∞) and the range (possible values of y) is also (-∞, ∞).
