The problem gives you the time in hours, but you're looking for your answer in minutes so change 1/10 of an hour to minutes first. To do this, multiply 1/10 by 60 to get 6 minutes. Since there are 4 quarters in a whole, multiply 6*4. It would take her 24 minutes to drink the whole shake

Answer:

n=−5

Step-by-step explanation:

n−4−3n=3n+6−3n

−2n−4=6

Step 2: Add 4 to both sides.

−2n−4+4=6+4

−2n=10

Step 3: Divide both sides by -2.

−2n /−2 =  10 /−2

n=−5

POLS HELP ME NOWWWW I DONT UNDERSTAND IT
Leni [432]

Answer:

B

Step-by-step explanation:

using the equation 'y = 12x', if you plug in zero for 'x' you get zero for 'y'; the only graph that has the point (0, 0) is (b)

also, the x-axis represents time so, as time increases, so does the number of calories burned (which is measured on the y-axis) -- not staying flat or decreasing

What is y=1/2x+4 in standard form?
zhuklara [117]
<h3>Answer:  x-2y = -8</h3>

===========================================

Explanation:

Multiply both sides by 2 to clear out the fraction

y = (1/2)x+4

2y = 2[ (1/2)x + 4 ]

2y = 2*(1/2)x + 2*4

2y = x + 8

Then move the x term over to the left side

2y = x+8

2y-x = 8

-x+2y = 8

Optionally we can multiply both sides by -1

-x+2y = 8

-1*(-x+2y) = -1*8

x-2y = -8

This is in standard form Ax+By = C with A = 1, B = -2, C = -8

The reason why I multiplied both sides by -1 was to make A > 0 which is what some textbooks use as convention. Of course -x+2y = 8 is equally valid too.

15/3x =5

x= 5

5+2y= 315

5-5+2y =315-5

2y = 310

2y/2 = 310/2

y=155

Step-by-step explanation:

450/45

10

2x+4y=450

2×5=10

10+(4×155)

=620/155

=4

10/5=2

1. Write a two-column proof for the following conjecture. You may not need to use all of the rows of the two-column table provid
marshall27 [118]

Answer:  

Given: ABCD is a parallelogram.

Prove: Angle A and B are supplementary and C and D are supplementary.

That is, m∠A + m∠B = 180° and m∠C + m∠D = 180°


                Statement                                                Reason

1. ABCD is a parallelogram              1. Given  

2.m∠A=m∠C and m∠B=m∠D         2. Definition of parallelogram.

3.m∠A+m∠B+m∠C+m∠D=360°      3. Definition of quadrilateral

4. m∠A+m∠B+m∠A+m∠B=360°     4. By substitution

⇒ 2( m∠A + m∠B ) = 360°

⇒ m∠A + m∠B = 180°

Similarly, m∠C + m∠D = 180°

5.∠A and ∠C are supplementary,  5. Def. of Supplementary

∠ B and ∠D are supplementary
