Hi there, please help:)

Answer:

the answer is 18

Step-by-step explanation:

5×6-10(2)+8

=30-20+8

=18

Answer:

Let x = speed for the first 96 miles

x - 9 = speed for the last 100 miles

Distance = (rate)(time), so time = (distance)/(rate)

(time for first part of trip) + (time for last part of trip) = 4 hours

So, (96)/(x) + (100)/(x - 9) = 4

Multiply both sides by the LCD (x)(x - 9) to get

96(x - 9) + 100x = 4x(x - 9)

96x - 864 +100x = 4x2 - 36x

4x2 - 232x + 864 = 0

Divide both sides by 4 to obtain x2 - 58x +216 = 0

(x - 4)(x - 54) = 0

x = 4 or x = 54

Note that x can't equal 4 because, in that case, x - 9 would be negative, so x = 54 miles per hour.

I think its C

Step-by-step explanation:

Answer:

the answer is c. I took the test and got it right!

Step-by-step explanation:

f(7) = 34

7² -5(7) +k = 34

49-35+k =34

14+k = 34

k = 34-14

k = 20

Step-by-step explanation:

f(7) = 34

7² -5(7) +k = 34

49-35+k =34

14+k =34

k = 34-14

k = 20

Step-by-step explanation:

Answer:  Approximately 21.667 km

This value as a fraction is 65/3, but I think the decimal form is probably more practical in real world settings.

======================================================

Work Shown:

20 min = 1/3 of an hour, since 20/60 = 1/3. In other words, there are three chunks of 20 minutes that make up a full hour.

distance = rate*time

distance = (65 kph)*(1/3 hr)

distance = (65*1/3) km

distance = (65/3) km

distance = 21.667 km which is approximate

Answer:

Distance rate=Rate x Time

Distance= (75 km/h) 20 mins

Convert 20 mins in hours= 1/3 h

Distance= (75 km/h) (1/3 h)= 25 km.....

Answer: [tex]\sqrt{11[/tex]

Step-by-step explanation: pythagorean theorem a^2 + b^2 =c^2

switch it to c^2 - b^2 = a^2

c=6 and b=5

(6)^2 - (5)^2 = 36-25 which is 11

11=c^2. to find c, square root 11. the simplest form for this is just [tex]\sqrt{11[/tex]

Answer:

x = 3 I think

Step-by-step explanation:

h. mmm yess I think

Answer:

(4x+5)°+(6x-10)°=145°

4x+6x+5-10=145°

10x-5=145°

10x=145+5

10x=150°

x=15

(6x-10)°=(6×15-10)°

=80°

The value of ∠XMN = 80.

An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint.

The value of total ∠LMN = 145.

∠LMN = ∠LMX +∠XMN

145 = (4x + 5) + (6x - 10)

145 = 4x + 5 + 6x - 10

145 = 10x -5

10x = 150

x = 15

Substitute the value of x in ∠XMN =  (6x - 10)

∠XMN =  6×15 - 10

            = 90 - 10

∠XMN = 80

Therefore, the value of the angle  ∠XMN = 80.

Step-by-step explanation:

When multiplying exponents with the same base, add the exponents:

[tex]\frac{6^{10-4} }{6^{-5+2} }[/tex] = [tex]\frac{6^{6} }{6^{-3} }[/tex]

Then use the negative exponent rule

Answer:

x = 11

Step-by-step explanation:

When solving for x, you want to get the variable by itself on one side of the equation. The first step is to subtract 10 from both sides. 43-10=33. So, it should look like:

3x = 33

Divide both sides of the equation by 3 to get x alone. 33/3 equals 11. So x =11. Hope this helped and lmk if you have more questions!!

0

Step-by-step explanation:

By inspection or finding points, we see that 2nd ave is perfectly flat, or in other words, has slope of 0.

If line 1 is parallel to line 2, it means their slopes are the same.

So, the new road parallel to 2nd ave has a slope of [tex]\boxed{0}[/tex].

Answer:

6x(3x + 1)(x - 7)

Step-by-step explanation:

First look for the greatest common factor of the 3 terms.

The GCF is 6x, so

18x^3 – 120x^2 – 42x

= 6x(3x^2 - 20x - 7)

Now we look to factor the quadratic expression in the parentheses:

The first and last coefficients are multiplied

3 * -7 = -21.

We look for 2 numbers whose product is -21 and whose sum is -20:

They are -21 and + 1 , so we write:

6x(3x^2 - 21x + 1x - 7)

= 6x [ (3x(x - 7) + 1(x - 7)]    Note that x - 7 is common, so:

= 6x(3x + 1)(x - 7)  Answer

Step-by-step explanation:

1. At the end of the 5th week he would have saved a total of $700

2. The amount of flour he would have at the closing time on 17th of the month will be 16kg

1.

Azad amount = $500

He wants to go on a holiday but he lacks sufficient money. This means the $500 in his possession is not enough.

He decided to save $40 dollars per week for a number of weeks to make up the deposits.

let

w = number of weeks

Therefore, his saving for any number of weeks will be

The amount he would have saved for 5 weeks will be

40×5=$200

The total amount in his possession at the end of the fifth week will be  200 + 500 = $700

2.

The baker has 400 kg of flour. The first day of the month he didn't use any flour. This means on the first day of that month the flour was still 400 kg. The amount he has on the 17th day of the month can be calculated below.

The 17th day simply implies he used the flour for 16 days, the first day of the month he didn't use anything. He uses 24 kg for each day. Therefore the amount he uses for 16 days will be

The amount he has at the closing time of 17 days of the month will be
