5x + 10y = 20
= 3y - 1

Answer:

1 hour and 45 min

Answer:

11.7

Step-by-step explanation:

Step 1: Our output value 39.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above, 39 = 100%.

Step 4: Similarly, x = 30%.

Step 5: This results in a pair of simple equations:

39 = 100%(1)

x = 30%(2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

39/x = 100%/30%

Step 7: Again, the reciprocal of both sides gives

x/39 = 30/100

------> x = 11.7

Therefore, 30% of 39 is 11.7

sorry for bad handwriting and forget - with slope

Answer:

A

Step-by-step explanation:

You should simplify this, here [tex]i[/tex] is like a variable.

Now here you just simplify the variables and calculate the numbers.

[tex]7-8 = -1[/tex]

[tex]3i+9i=12i[/tex]

equals

[tex]-1+12i[/tex] which is "A"

Step-by-step explanation:

Answer:

He averaged 2.75 touchdowns per game during the stretch.

Step-by-step explanation:

Its a 8 game stretch, he scored 22 touchdowns during the stretch.

So divide 22 by 8 to get 2.75 to get the average touchdowns per game

1). 2/3 ÷ 3/6

=> 2/3 ÷ 3/6

=> 2/3 × 6/3

=> 2/1 × 2/3

=> 4/3

2). 1/5 + 3/4

=> 1/5 + 3/4

=> 1 × 4/5 × 4 + 3 × 5/4 × 5

=> 4/20 + 15/20

=> 4 + 15/20

=> 19/20

3). 15/3 × 21/5

=> 15/3 × 21/5

=> 15 × 21/3 × 5

=> 315/15

=> 21 × 15/1 × 15

=> 21

Answer:

  not generally

Step-by-step explanation:

The basic log function has a vertical asymptote where its argument is zero. It has a positive slope for all positive arguments. It tends to infinity as the argument tends to infinity. There is no horizontal asymptote.

__

A log function can be made part of a larger expression in a way that would give the expression a horizontal asymptote. For example, the function ...

  f(x) = 1/log(x)

has a horizontal asymptote at f(x) = 0. (This asymptote is approached very slowly.)

Answer:

N = 17.1°

P = 72.9°

168.96 = NQ

Step-by-step explanation:

13.6 ^2 = 4^2 + NQ

184.96 - 16 = NQ

168.96 = NQ

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

N = 17.1°

P = 72.9°

Answer:

Reflexive property

Step-by-step explanation:

The reflexive property of congruence states that any geometric shape is congruent to itself.

Answer:

C) Symmetric Property

Step-by-step explanation:

The Symmetric Property states that  If A is congruent to B, then B is also congruent to A. This implies that the congruence is symmetric.

Khan Academy also states that:

When a relation  has a symmetric property, it means that the if relation is true between two things, it is true in either order.  If VW ≅ XY, then XY ≅ VW.

Therefore, the correct answer is C) Symmetric Property.

Use Pythagoras Theorem

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

Where c is the hypotenuse of the right angle triangle ,and a and b the other sides. Just substitute the values and get your answer.

Answer:

they are both correct due to the commutative property

Answer:

Neither, slopes are 1/4 and 5/6

Step-by-step explanation:

Let's find the slope for Line 1: (-3,-1) and (-7,-2)

m1 = (-2+1)/ (-7+3)

= -1/-4

=1/4

Line 2: (2.-1) and (8,4)

m2= (-4+1)/ (8-2)

= -3/6

= - 1/2

These slope values are not the same, so the lines are not parallel. The slope values are also not negative reciprocals, so the lines are not perpendicular. Then the answer is

Neither, slopes are 1/4 and 5/6

Answer:

85°

Step-by-step explanation:

The sum of all angles in a triangle is 180°

180 = y + 37 + 58

y = 180 - 37 - 58

y = 85

Answer:

85 degrees

Step-by-step explanation:

y+95 degrees=180 degrees

y=85 degrees

Step-by-step explanation:

Formula in finding the trapezoid's area:

(note: altitude is also known as the height)

Area = 1/2 × 5 × (6 + 8)

A = 1/2 × 5 × 14

A = 2.5 × 14

A = 35

The area of your trapezium is 35!

Step-by-step explanation:

Because you use trial and error to see what x is and it says integet meaning 1,2,3,4,5,6... and their opposites.

Answer:

x ≈ 5 using math and x ≈ 4 using trial and error

Step-by-step explanation:

[tex]6^x = 3800[/tex]

[tex]x = log_{6}*3800[/tex]

x ≈ 4.6 ≈ 5

Hope this helped!

Trial and Error:

6 ^ 4 = 1276

6 ^ 5 = 7776

3800 is closer to 1276, so x = 4

The inequality which represents the number days Joe will need to to run in order to meet his goal is [tex]4d\geq 60[/tex].

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions is called inequality.

According to the given question.

Joe plans to run 4 miles every day.

And his goal is to run at least 60 miles.
