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:

[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:

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

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

Step-by-step explanation:

Kim is 5 years older than Scott.

Kim's mum is 3 times Kim's age.

Scott's dad is 3 times Scott's age.

Let age of Scott = y years

Then Kim's age = (y+5) years

Kim's mum age = years

Scott's Dad age = years

Difference between Kim's mum age and Scott's Dad age = Kim's mum age - Scott's Dad age = (3y+15) - (3y) = 15

x is greater that 8

Step-by-step explanation:

this is because if the quotient of 2 and x has to be greater that 4 then 2 divided by 8 (8 being x) is 4 so anything substituting x has to be greater that 8.

Answer:

A: -10

Step-by-step explanation:

Answer:

210

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.

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]

Step-by-step explanation:

Answer:

A. ∠B = 55°; ∠D = 55°

Step-by-step explanation:

Hope this helps :)

The measures of angles B and D are option (a) ∠B = 55°; ∠D = 55°

A parallelogram is a shape whose opposite sides are parallel and congruent.

Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.

Given; Angle B is (2 n + 15) degrees and angle D is (3 n minus 5) degrees.

The following is the step to determine the measures of angles B and D

We have,

angle B = 2n + 15

angle D = 3n - 5

The angles are opposite angles;

So,

angle B = angle D

This gives us;

2n + 15 = 3n - 5

Now Collect like terms;

3n - 2n = 15 + 5

n = 20

Then Substitute 20 for n in angle B = 2n + 15

angle B = 2 * 20 + 15

angle B = 55

Hence, the measures of angles B and D are option(a) ∠B = 55°; ∠D = 55°
