b.(x,y) > (x+6, y+6)
c.(x,y) > (6x, 6y)
d.(x,y) > (-y, x)

Answer:

The answer is angleCGD....only

Answer:

15:    39 degrees

17:    26 degrees

Step-by-step explanation:

15. straight line=180 degrees

51+90+c=180

141+c=180

c=180-141

c=39 degrees

17.straight line=180 degrees

2x+2x+76=180 degrees

4x+76=180

4x=180-76

4x=104

x=26

Answer:

15.39 degrees

17. I got 19 degrees for x

Step-by-step explanation:

17.

2x+2x= 76

4x=76

devide 4x and 76 by four and you would get 19

4(19)=76

4x19=76

Answer:

2160

Step-by-step explanation:

multiply the value of the yards (60) by 36

Answer:A. y ≥ 2

Step-by-step explanation:

First the line is solid, a complete line not dotted so the inequality sign to use is : ≥  or ≤

The points have their y-coordinate vale as 2, (−5, 2) and (3, 2), this means the line crosses the y-axis at y=2 but because the shaded part is above this line, then the correct inequality will be :

y ≥ 2

Answer:

equation: -3 + y = -8

solution y: -5

Step-by-step explanation:

Answer:

Joe bought 20 seed corn bags and 30 bags of dog food

Step-by-step explanation:

x + y = 50

5x + 3y = 190

Subtract y from both sides of the first equation

x = 50 - y

Put x into the second equation

5(50 - y) + 3y = 190

Distribute the 5

250 - 5y + 3y = 190

Combine like terms

250 - 2y = 190

Subtract 250 from both sides

-2y = -60

Divide both sides by -2

y = 30

Put y into the first equation

x + 30 = 50

Subtract 30 from both sides

x = 20

Answer:

E. total weight = weight of crate + (weight of one apple) × (number of apples)

Step-by-step explanation:

Total weight = 60 lb

Weight of crate = 4.5 lb

Weight of one apple = 0.37 lb

Let's assume, the weight of apples in the crate is "x".

x = Total weight - weight of crate ----- 1

Let's assume, the number of apples in a crate is "y".

y = x ÷ (weight of one apple) ------------ 2

[make x the subject of equation 2]

x = y × (weight of one apple) ------------ 3

[put equation 3 into equation 1]

y × (weight of one apple) = total weight - weight of crate

[make "total weight" the subject]

Total weight = y × (weight of one apple) + weight of crate.

[y is the number of apples)

Total weight = (number of apples) × (weight of one apple) + weight of crate

27÷9=3

Answer:

1/3

Step-by-step explanation:

9/27 divided by 9 = 1/3

Answer:

4/3 : 1

Divide 1/3 by 4

formed as:

Keep 1/3 change ÷ with multiplication and put a 1 under the 4 and flip it

1/3 ÷ 4/1 = 4/3

2 divided by 3 = 1 ,ig?

Step-by-step explanation:

[tex] = 1 \frac{1}{5} \div \frac{1}{10} \\ [/tex]

Answer:

top right

Step-by-step explanation:

if you solve an equation for a triangle using this method you'll get this result

Answer:

The correct answer is 24

Step-by-step explanation:

to solve this you will need to use the pathagreom theorum

a^{2}+b^{2}=c^{2}

A= one side lenth

B= the secons side lenth

C= hypotnuse

It is helpfull to draw out the situation

you know that the latter is 25 ft, that is your hypotnuse

you also know that the 7 ft away from the base of the building is one of the side lenths, lets call it side a

so plug the numbers into the equation

7^2 + b^2 = 25 ^2

you leave b^2 alone because that is the side you are trying to find

now square 7 and 25 but leave b^2 alone

49 + b^2 = 625

now subtract 49 from both sides

b^2 = 576

now to get rid of the square of b you have to do the opposite and square root both sides removing the square of the B and giving you the answer of..........

B= 24

Answer:

The top right flower pot can't hold all the soil in the bag.

Step-by-step explanation:

Do the volume of each flower pot

Top left flower pot = 1200 cubic inches

Top right flower pot = 640 cubic inches

Bottom left flower pot = 1000 cubic inches

Bottom right flower pot = 1000 cubic inches

The top right flower pot is the only flower pot with a volume less than 924 cubic inches.

Step-by-step explanation:

Answer:

( a= 5/2 )

Step-by-step explanation:

         10/4    4a/4

Divide the numbers

Cancel terms that are in both the numerator and denominator

Move the variable to the left

Answer:

2.5 or [tex]2\frac{3}{6}[/tex] or [tex]2\frac{1}{2}[/tex]

Step-by-step explanation:

[tex]\frac{5}{6} +\frac{5}{6} +\frac{5}{6} =\frac{15}{6}[/tex]

simplify: 15÷6=2.5

So the baby napped for 2.5 hours or [tex]2\frac{3}{6}[/tex] or [tex]2\frac{1}{2}[/tex]

Answer: No, he will not meet his goal.

Step-by-step explanation:

You have to turn the denominator into a common denominator - 6 and 4 can both be multiplied to get 12 (6 by 2 & 4 by 3)

Then you have to multiply the numerator by 2 or 3 (for 1/6 you have to multiply both numbers by 2) (for 1/4 you have to multiply both numbers by 3)

Then you have to add the numbers (which should be 2/12 & 3/12)

So your answer should be only 2 5/12 (which is 1/12 less than needed)

To get the price per pound paid in the question, divide $ by # of pounds = 0.60

Answer:

22 km

Step-by-step explanation:

There is no mention about the triangle, but this can only be solved if the triangles are similar.

I assume the triangles are similar, so the lengths of corresponding sides are proprtional.

PR/TR = PQ/ST

24/33 = 16/ST

8/11 = 16/ST

1/11 = 2/ST

ST = 22

Answer: 22 km
