265+48=313

553-313=240

240/60=6

Answer:

equation : 265 + 48T = 553

T = 6 hours

Step-by-step explanation:

equation

553 - 265 = 288

288 /48 = 6

the number of hours spent is 6

equation : 265 + 48T = 553

T = 6 hours

Answer:

B. Angles ABD and BAD

Step-by-step explanation:

The way that you tell which angles are congruent, are based on the angle marks. Angle A and C are congruent because they both contain 3 of the congruency marks, meaning they would equal the same degree. The answer is B because starting with angle BDA, B is your starting point, whereas D is the angle and A is the point you end on. With angle BAD, you start at point B and end at D, making angle A the one you're looking at. Because angle A contains 3 congruency marks, while angle B only contains one, this makes the two angles NOT congruent. Hope this helps. :)

Answer:

angles ABD and BAD

Step-by-step explanation:

The congruent angles match in the number of angle markings on the diagram.

Answer:4x=1/6

because of how its written you would be multiplying 4x by 1/6 if they asked you to solve it. but since they asked you to write the equation all you have to do is put 4x on one side of the equal sign and 1/6 on the other so if they ask you to solve it all you have to do is multiply both sides by 1/6

Answer:

The perimeter is 16 units.

Answer:

                1 C) 23

               2 D) x + y + 2

Step-by-step explanation:

1.

a = 1 ,  b = -23, c = 130

b²-4ac = (-23)²- 4×1×130 = 529 -520 = 9>0

if solutions (A=x₁, B=x₂) exist (b²-4ac≥0) then based on vieta's formula:

[tex]A+B=x_1+x_2=-\dfrac{b}a=-\dfrac{-23}1=23[/tex]

2.

sum of two even integers is na even integer

sum of two odd integers is na even integer

only sum of an even integer and an odd integer is an odd integer

x is even and y is odd so 2x is even and ±2y is even and x+y is odd

1 is odd and 2 is even which means:

2x±2y is even,

x+y + 1 is even

x-2y is even

only x+y+2 is odd (as sum of odd x+y and even 2)

Answer: Substitution

Step-by-step explanation:

GIVEN:

y=3x

2x+4y=12

Then, 2x+4(3x)=12

-----------------------------------------

Substitution: replacing one variable in terms of another variable.

As we can see from the given aspects, y=3x, and the conclusion expression has no y instead of 3x. This means it represented y in terms of x, which fits the definition of substitution that replaces one variable.

Hope this helps!! :)

Answer:

x = 7

Step-by-step explanation:

0 = 4(x+5) + 8

expand:

0 = 4x + 4*5 + 8

0 = 4x + 20 + 8

0 = 4x + 28

simplify

4x = 28

simplify

x = 28 / 4

Answer:

Yes, they can buy all the bags.

Step-by-step explanation:

Owen's parents need to buy 6 bags for $2.49 each.

So, we need to calculate the total price:

$2.49 * 6 = $14.94

Since the bags cost $14.94, and Owen's parents have $20.00, they have enough money to buy all 6 bags. 14.94 < 20.00

Hope this helps!

Answer:

They will have enough money to spend on 6 goodie bags

Step-by-step explanation:

First, you need to mutiply $2.49 × 6 and then you get 14.94

then you need to subtract $20.00 - 14.94 to get $5.06

so your answer should be,  ¨Owen´s parents will have $5.06 left after spending $14.94 of their $20.00 on goodie bags¨

First, isolate x. To do that add 3.5 to each side

x - 3.5 =  -3.1

  +3.5    +3.5

x= 0.4

Answer:

Step-by-step explanation:

X-3.5= -3.1  add 3.5 each side.

X = 3.5 - 3.1 simplify

X = 0.4   done!

Answer:

  Multiplying by 1 does not change the ratio

Step-by-step explanation:

Multiplying a/b by c/c gives the equivalent ratio (ac)/(bc) because c/c is 1, the multiplicative identity element. Multiplying by 1 does not change the ratio.

A train traveled at a constant speed for six hours and traveled a distance of 408 miles. What is the best estimate of the number of miles the train could travel in 2.5 hours? *

Answer:

20 people

Step-by-step explanation:

The first step is to find out how many people are in 1/7 of the group. To do this, we divide 28÷7, and our answer is 4.

28÷7=4

Our next step is to find out how many people are in 2/7 of the group. We would double the 4, since 1/7 doubled is 2/7, and get 8.

4 x 2= 8

Now we know that 8 people ordered ice cream. To find the number of people who ordered the special, we subtract 8 from 28.

28-8= 20

Therefore, 20 people ordered the special. Hope this helps!

If 28 people ordered dessert, 2/7 ordered ice cream then 20 people ordered the rest.

Two or more expressions with an Equal sign is called as Equation.

Given that 28 people ordered dessert.

2/7 ordered ice cream and the rest ordered the special how many people ordered the special.

1/7 of the 28 people is 4.

Our next step is to find out how many people are in 2/7 of the group. We would double the 4, since 1/7 doubled is 2/7, and get 8.

4 x 2= 8

we know that 8 people ordered ice cream.

To find the number of people who ordered the special, we subtract 8 from 28.

Twenty eight minus eight equal to twenty.

28-8= 20

Hence, 20 people ordered the special.
