Answer:

x= -7

y=0

Step-by-step explanation:

you want to get one variable alone and substitute it into the other equation

in this case, get the y in -5x+y=35 alone

y=5x+35

now substitute this into 3x+2y= -21

3x+2(5x+35)= -21

3x+10x+70= -21

13x=-91

x= -7

now substitute x into one of the equations

3(-7)+2y= -21

-21+2y= -21

2y=0

y=0

Answer:

1.25 5/4

hence 5/4...

1.25

Answer:

w=9

Step-by-step explanation:

To solve for this answer, solve the equation like so:

x/7 ≥ -6

Because you have x over 7 (meaning it is a fraction), do the opposite of the fraction (dividing), and multiply

x/7 ≥ -6

x7    x7

x ≥  -42

Answer:

I would think its 120

Step-by-step explanation:

Answer:

120*

Step-by-step explanation:

Answer:

12

Step-by-step explanation:

Let :

x = number of Pizza's

y = number of burritos

x + y = 20 - - (1)

2.75x + 3.50y = 61 - - (2)

From (1) :

y = 20 - x

2.75x + 3.50(20 - x) = 61

2.75x + 70 - 3.50x = 61

-0.75x = 61 - 70

-0.75x = - 9

x = 9/0.75

x = 12

12 pizza slices

Answer:

1560.38

Step-by-step explanation:

As far as I know, a sales tax is never calculated until money changes hands. So the rebate is the first amount to take place.

1560 - 100 = 1460

Now if the purchaser agrees to this amount and does anything to pay partially or in full, the tax is added.

Total Cost = 1460 * (1.06875)

Total Cost = 1560.38

Edit

You have to be very careful when you use a term like rebate. Rebate is a very special kind of discount. Your purchase has to qualify for a rebate. Apparently this one does. If you are willing to spend 1560 on something, the merchant selling the product offers you a rebate to help you decide.

If the TV cost is 1200 you may not get the rebate.

Answer:

yes, it is a right triangle and ∡Q is the right angle

Step-by-step explanation:

if the slope of QR is the opposite reciprocal of QS then the two segments are perpendicular and form a 90° angle

slope of QR:  -3 - (-1) ÷ 2 - 0  = -2 ÷ 2 = -1

slope of QS:  -3 - (-1) ÷ 2 - 4  = -2 ÷ -2 = 1

-1 and 1 are opposite and reciprocal so m∡Q = 90°

Answer:

[tex]Yearly = \$59.88[/tex]

Step-by-step explanation:

Given

[tex]Monthly = \$4.99[/tex]

Required

Determine the yearly cost

To do this, we multiply the monthly subscription by 12

[tex]Yearly = Monthly * 12[/tex]

[tex]Yearly = \$4.99 * 12[/tex]

[tex]Yearly = \$59.88[/tex]

Hence, the yearly servics cost is $59.88

Answer:

a +b = 2

Step-by-step explanation:

a +3 = 6

    a = 6 -3

   a = 3

Plugin  a =3 in the equation,

a*b +5*a +3*b + 15 = 24

3b + 5*3 + 3b + 15 = 24

3b + 15  + 3b + 15 = 24      {combine like  terms}

3b + 3b + 15 + 15 = 24

             6b  + 30  = 24           {Subtract 30 from both sides}

                       6b = 24 -30

                      6b = -6               {divide both sides by 6}

                         b = -6/6

b = -1

a + b = 3 + ( -1)

         = 2

Answer:

[tex]\frac{1}{10}[/tex]

Step-by-step explanation:

note that in terms of the given fraction

1 = [tex]\frac{10}{10}[/tex] , then

[tex]\frac{9}{10}[/tex] + [tex]\frac{1}{10}[/tex] = [tex]\frac{10}{10}[/tex] = 1

Answer:

[tex] \frac{9}{10} + x = 1 \\ x = 1 - \frac{9}{10} \\ x = \frac{(10 - 9)}{10} \\ \boxed{x = \frac{1}{10} } \: is \: the \: required \: number[/tex]

Answer: what’s the problem

Step-by-step explanation:

9514 1404 393

Answer:

Step-by-step explanation:

The function puts a minus sign on 3 times the magnitude of the input.

1. y = -|3×17| = -51

2. y = -|3×10| = -30

3. y = -|3×20| = -60

4. -6 = -|3x|

  2 = |x| . . . . divide by -3

  x = ±2 . . . . two possibilities

Step-by-step explanation:

2+6x= -10 + 11(x + 4)

2+ 6x = -10 + 11x + 11(4)

2 + 6x = -10 + 11x + 44

2+ 6x = 11x + 34

6x - 11x = 34 - 2

-5x = 32

x= - 32/5

Answer:

Step-by-step explanation:

1) multiplication- 2+6x=-10+11x+44

2)addition or subtraction- 2+6x=11x+34

3)isolate the variable- -5x=32

4)divide 32 by 5= x=6.4 or 32/5

Answer: 7/15

Step-by-step explanation:

1. Most probability questions are asking to find the favourable outcomes over the number of total outcomes.

The favourable outcomes will be green marbles.

There are 7 green marbles, so there are seven favourable outcomes.

There 6 + 7 + 2 = 15 total outcomes.

Thus, there are 7/15 favourable outcomes.

Answer:

4.5 m/s

Step-by-step explanation:

acceleration is the change in velocity divided by time. so, 25 m/s going to 0 m/s (stop), which is 25, divided by 5.5 seconds is 4.5 m/s
