The answer is D. x- 0.25x

If the number that we have is .75x, then we will only have 3 quarters of our total and will take one quart away. 25 is one quarter.

Answer:

128

Step-by-step explanation:

1/2 x (10+22) x 8 =128

Answer: First we need to create an equation

x+x+2+x+4=156

3x+6=156

3x=156–6

3x=150

x=50

The answer is 50,52, and 54.

Check

50+(50+2)+(50+4)=156

50+52+54=156

Answer:

bisecting line BC

Answer:

slope is -2/3

Step-by-step explanation:

y = mx+b

m = slope

b = y-intercept

given: y = -2/3x

in this case we don't have a b so make it an automatic 0

now we have y = -2/3x +0

slope is m, so our slope is -2/3

Answer:

x>=-8 and a colored in point on negative eight with an arrow to the right

Step-by-step explanation:

-7x<=56 is the given

to solve, we would divide both sides by -7. However, when dividing an inequality, the direction of the inequality sign flips (if you've heard the alligator example, the mouth opens in the opposite direction it was before)

so we know have x>=-8

On the number line, the colored in dot represents that the value it is on is within the set, and since this can also be equal to -8 we have to use a colored in dot because its within the possible values. If it was not <= or >= then we would use an open circle to represent it cannot be that value but can be anything in the direction the arrow is pointing.

The arrow would point to the right because x can be larger or greater than -8 as well

Answer:

x=2.5

Step-by-step explanation:

because 4x-2=2x+3

4x-2x=3+2

2x=5 divide both by 2 it gives 2.5

Answer:

b = 5

Step-by-step explanation:

2.6 b= 30 - 17

2.6 b = 13

b = 13 ÷ 2.6

b = 5

Answer:

proof: answer is 2/13

1 / 6.5 = m

m = 0.153846154

10/65 = m

m = 2/13

2/13 = m

m = 0.153846154

Therefore we could show multiplication proof

m = 10/65  =   m = 2/13

2 x 5 = 10

13 x 5 = 65

Step-by-step explanation:

See attached graph of y = 6.5x+75.5

plotting the graph

1. Mark y intercept at 75.5 as given in the equation

2. find the slope to whole numbers

m =  10 across / 65 across = 6.5 slope

Mapping Pythagoras   10^2 +65^2 = c^2

sqrt 100 + sqrt 4225 = c^2

c^2 = sqrt 4225 = 65.7647322 = 65.8

0.7647322 / 65 = 0.0117651108 = 100th

65 + 0.0117651108 = 65.011765.....

Therefore 10 across / 65.0118  down

or 10 across  / 65 down is another way to graph, as seen on graph.

m = 10/65  =   m = 2/13

2 x 5 = 10

13 x 5 = 65

Step-by-step explanation:

the function is y=x+1

Answer:

C

Step-by-step explanation:

The first one (0,7) tells you that when x isn't there, the amount of money is 7.

That means that the y intercept is 7.

When x = 1 the total is 15

Money saved = ax + 7

15 = a*1 + 7                         Subtract 7

15-7 = a + 7-7

a = 8

The equation is f(x)  = 8x + 7

Answer:3[tex]\frac{1}{2}[/tex] hours

Step-by-step explanation:

You plan to go a total distance of 21 miles. At 6 miles per hour it takes you

[tex]\frac{21}{6}[/tex] hours or3 and [tex]\frac{3}{6}[/tex] which equals 3 and 1/2 hours

Answer:

Im sure of 1.5

Step-by-step explanation:

None

Answer:

1.6 is a rational number while 1.4 is not

16 and 10 are rational numbers so 1.6 will also be a rational number

√2 is 1.4 while the square of 1.4 is not 2

√2.56 is 1.6 and the square of 1.6 is 2.56

 Answer:

In order to compare the fractions we can first obtain the LCM of the denominators of the two fractions and that is to say

= LCM of 5 and 3 which is 15

= [tex]\frac{2}{5} * 15[/tex]

=6

and also:

= [tex]\frac{1}{3} * 15[/tex]

=5

So in conclusion the numbers 6 and 5 will determine the sign to be used and since 6 is for [tex]\frac{2}{5}[/tex] and 5 is for [tex]\frac{1}{3}[/tex] and numerically 6 is greater than 5 therefore:

[tex]\frac{2}{5} > \frac{1}{3}[/tex]

Answer:

1 1/2 gallons

Step-by-step explanation:

1/4 * 6 = 6/4 = 3/2

1/6+1/6+1/6+1/6+1/6+1/6 = 1 whole wall

that means it takes 6 times 1/4 gallon to finish the wall

Answer:

y = 7/9x - 87/9

Step-by-step explanation:

9y = 7x-4

y = 7/9x - 4/9

-5 = 7/9(6) + b

-45/9 = 42/9 + b

b = -87/9

Answer:

correct answer is b rotation

Answer:

b = 3

Step-by-step explanation:

All angles in a triangle always equal 180*

so 180 - 100 + 41 = 39

39/13 = b

3 = b

Answer yes, no

Step-by-step explanation:

for number one, 12.01 and 11.999 are being compared

let’s start by looking at the non decimal digits

12 is bigger than 11, so we can assume that anything bigger than 12 is less than anything less than twelve, so the answer is yes

for number two, they are 2 different numbers, so they are not equal

Answer:

8x; x ≤ $23.75

Step-by-step explanation:

You have to buy 8 trains with 190 dollars. You can't use more money or have more trains.

8x ≤ 190

Divide by 8 on both sides.

x ≤ $23.75 per train
