Step-by-step explanation:

Answer:

Step-by-step explanation:

10+60t≤280

60t≤280-10

60t≤270

6t≤27

2t≤9

t≤9/2

t≤4.5

t=4 hours

first subtract $10 from$280 and you get $270

270 divided by 60 = 4.5

so the answer is four and a half hours

Answer:

The distance of the line segment AB =17

Step-by-step explanation:

Explanation:-

Given points are X( -8,5) and Y(7,-3)

The distance of the line segment

       AB = [tex]\sqrt{(x_{2}-x_{1} )^{2} +(y_{2} - y_{1} )^{2} }[/tex]

      [tex]AB = \sqrt{(7-(-8) )^{2} +(-3-5 )^{2} }[/tex]

    [tex]AB = \sqrt{(7+8)^{2} +(-5-3)^{2} }[/tex]

    AB = [tex]\sqrt{225+64}[/tex]

   AB = 17

The distance of the line segment AB =17

Answer:

Well 240 divided by 4 equals 60 which is how many miles he can travel in 1 hour.

Step-by-step explanation:

So 60 multiplied by 10 equals 600.

That means Moby can travel 600 miles on his jetpack in 10 hours

Answer:

x=4, y=2 (4,2)

Step-by-step explanation:

This is a system of equations.

-2x+2y=-4

2x-3y=2

I'll use the elimination method to solve this.

add the two equations together.

what's left:

-y=-2

multiply both by -1

y=2

now, substitute 2 as y into one of the other equations.

For example:

-2x+2(2)=-4

-2x+4=-4

-2x=-8

x=4

hope this helps!

Algebra I

Step-by-step explanation:

Step 1: Define Systems

-2x + 2y = -4

2x - 3y = 2

Step 2: Rewrite Systems

2x - 3y = 2

Step 3: Redefine Systems

-2x + 2y = -4

2x = 3y + 2

Step 4: Solve for y

Answer:

A: -10

Step-by-step explanation:

The solution of equation is -7, the number of solutions to equation is one.

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

The given equation is 30+ 6p = 7(p + 6)- 5

Thirty plus six times of p equal to seven times of p plus six minus five.

p is the variable in the equation.

30+ 6p = 7(p + 6)- 5

Apply distributive property on right hand side.

30+6p=7p+42-5

Take all the variables on one side and constants on other side.

30-42+5=7p-6p

-7=p

p=-7

Hence, the solution of equation is -7, the number of solutions to equation is one.

[tex]log(9^2) = 2\ log(9)[/tex]

Step-by-step explanation:

Given

[tex]log(9^2)[/tex]

Required

Select an equivalent expression

To answer this, we apply the following law of logarithm.

[tex]log(a^b) = b\ log(a)[/tex]

So:

[tex]log(9^2) = 2 * log(9)[/tex]

[tex]log(9^2) = 2\ log(9)[/tex]

Hence:

The equivalent expression is (a). [tex]2\ log(9)[/tex]

Answer:

Step-by-step explanation:

To find the scale factor from ΔDEF to ΔRST, find a measure on ΔDEF and a corresponding measure on ΔRST, then write them in the form required for the scale factor.

Here, there are numbers on DE, RS, and ST. We see by the similarity statement ΔDEF ~ ΔRST that DE corresponds to RS, so the scale factor is ...

  ΔDEF : ΔRST = DE : RS = 3 : 4 . . . scale factor

__

Using that scale factor, you can write a proportion to find the value of x.

  3 : 4 = x : 16  ⇒  3/4 = x/16

Multiplying the fraction equation by 16, we have ...

  x = 16(3/4)

  x = 12
