2. 4(5x-2)=2(9x+3)  x=7

Step-by-step explanation:

1. 2(x+3)=x-4

2x+6=x-4

2x=x-10

x=-10

2. 4(5x-2)=2(9x+3)

20x=18x+14

2x=14

x=7

Answer 2

Answer:

1) x=-10

2)x=7

Answer: a. 2.3 x 10³

Step-by-step explanation:

You first divide 6.9 by 3 which is 2.3

When dividing numbers with exponents you subtract them, so you subtract th exponent 8 by the exponent 5 which is 3 (10³)

evaluate (101.5)²-(100.5)²​

Answers

You can exploit the difference-of-squares identity,

a² - b² = (a - b) (a + b)

Then

101.5² - 100.5² = (101.5 - 100.5) * (101.5 + 100.5)

101.5² - 100.5² = 1 * 202

101.5² - 100.5² = 202

Andy's phone plan charges $0.45 per text message plus a $20 monthly fee. Jeff's plan charges $0.20 a text plus an additional $35 monthly fee. Which equation can be used to determine when the phone plans will cost the same based on the number of texts?

Answers

Answer:

20+0.45x=35+0.20x

Step-by-step explanation:

From the information given, you can say that Andy's plan cost would be equal to Jeff's plan cost and then solve for the number of text to find when the phone plans will cost the same:

20+0.45x=35+0.20x, where x is the number of texts

Now, you can solve for x:

0.45x-0.20x=35-20

0.25x=15

x=15/0.25

x=60

According to this, the equation that can be used to determine when the phone plans will cost the same based on the number of texts is 20+0.45x=35+0.20x.

A car used 1 2/5 gallons of gasoline to travel 50 3/4 miles. How far can the car travel on 1 gallon of gasoline?

Answers

Answer:

36 1/4

Step-by-step explanation:

you had to divide the miles into gallons

A car can travel [tex]36\frac{1}{4}[/tex] Miles on 1 gallon of gasoline.

What is an improper fraction?

A fraction that has the numerator higher than or equal to the denominator is said to be an improper fraction.

Given, a car used [tex]1\frac{2}{5}[/tex] gallons of gasoline to travel [tex]50\frac{3}{4}[/tex]  Miles.

In order to solve the problem:

First, we solve covert the mixed fraction to improper fraction.

That means,

[tex]1\frac{2}{5}[/tex] = 7/5

 [tex]50\frac{3}{4}[/tex] = 203/4

That means,  a car used 7/5 gallons of gasoline to travel 203/4 miles.

To find the distance of car can travel on 1 gallon of gasoline:

203/4 ÷ 7/5

= 203/4 x 5/7

= [tex]36\frac{1}{4}[/tex] Miles.

Therefore, car can travel [tex]36\frac{1}{4}[/tex] Miles on 1 gallon of gasoline.

what is the slope or the line going through (0,0) (6,8) A: -6/8 B: -3/4 C: 3/4 D: 8/6

Answers

Answer: D) 8/6

Start at (0,0). To get to the other point, you must move up 8 units and move to the right 6 units.

slope = rise/run = (change in y)/(change in x) = 8/6

Or you could use the slope formula

m = (y2-y1)/(x2-x1)

m = (8-0)/(6-0)

m = 8/6

Normally I would reduce, but your teacher has decided not to.

8/6 reduces to 4/3 when you divide both parts by 2.
