Answer:

They are both proportional.

Tank A = .00375 minutes/gallon

Tank B = 2/600 or ~0.003 minutes/gallon

Step-by-step explanation:

They are both proportional because as time increases, the amount of gallons increases.

Tank A unit rate

Tank B unit rate

Rate = rise / run

Choose points on the graph that has definite points.

Tank A = (1.5 mins - 0.75 mins) / 200 gallons

Tank A = .00375 minutes/gallon

Tank B = (2 mins - 0 mins) / 600 gallons

Tank B = 2/600 or .003 minutes/gallon

Answer:

A,B and D are correct
10) The LCM of 6 and 12 is 12

Step-by-step explanation:

For the first question:

$2\frac{1}{2}$ < $2\frac{3}{4}$ ✅
-1.25<-0.75 is correct as -0.75 is closer to zero meaning it is bigger ✅
1.75<-1/4 is incorrect as negative numbers are smaller than positive numbers ❎
1.75>0.5 ✅
$2\frac{1}{2}$ > $2\frac{3}{4}$ ❎
-1.25>-1/4 is incorrect as they are equal

For the second equation:

Multiples of 6 are:

6,12,18...

Multiples of 12 are:

12,24,36...

So the lowest one in both is 12

Birds burgers barn sold 485 hamburgers today. The number sold with cheese wise half the number sold without cheese. How many of

frez [133]

Answer:

The number of hamburgers sold with cheese was 165 and the number of hamburgers sold without cheese was 330

Step-by-step explanation:

The correct question is

Birds burgers barn sold 495 hamburgers today. The number sold with cheese wise half the number sold without cheese. How many of each kind were sold?

Let

x -----> the number of hamburgers sold with cheese

y -----> the number of hamburgers sold without cheese

we know that

$x+y=495$ -----> equation A

$x=\frac{1}{2}y$ ----> equation B

substitute the equation B in equation A and solve for y

$y+\frac{1}{2}y=495$

$\frac{3}{2}y=495$

$y=495(2)/3$

$y=330$

Find the value of x

$x=\frac{1}{2}330=165$

therefore

The number of hamburgers sold with cheese was 165 and the number of hamburgers sold without cheese was 330
