x = a number

4(x + 5) = x - 1

Now, let's distribute the 4

4x + 20 = x - 1

Subtract x and 20 from both sides.

3x = -21

Divide both sides by 3

x = -7

WILL MARK BRAINLIEST!! 5 POINTS!!
Anton [14]
The speed of the car per minute is 3,520 feet (choice c). This is because in order to solve the problem, you have to convert 40 mi/h into feet. Since there are 5,280 feet per mile, you have to do 5,280 x 40, which is 211,200, which is the number of feet per hour. But, the question is asking for ft/min. There are 60 minutes in an hour, so you divide 211,200 by 60, which is 3,520. So, the speed of the car per minute is 3,520 feet.

sveticcg [70]

The options aren't given, however, the range of amount spent could be calculated

Answer:

Kindly check explanation

Step-by-step explanation:

Paula purchase 3 dvd and 7 cds and spent between 90 and 100. Each dvd costs the same amount the price of cd is 10 select all amounts that could be the price of the dvd

Given that :

DVD costs the same amount

Number of DVD's = 3

Cost of cds = 10

Number of cds = 7

Total cost of cd's = 10 * 7 = 70

Let the price of DVD = x

Total amount spent = 90 - 100

Lowest price of DVD :

(amount spent - price of cd) / number of dvd

(90 - 70) / 3 = 20 /3 = 6.667

Highest price :

(100 - 70) / 3 = 30 / 3 = 10

Hence the pice of each DVD will range between /

6.6666 and 10.

Hence, prices listed within the range above are possible.

Can someone please help me.
Natasha2012 [34]

Answer:10√2

Step-by-step explanation:

∆ABC is a right angle triangle

Angle A + Angle B + angle C = 180

There angel B = 180-135= 45

Angle A = Angle B

Therefore AC= BC=10

By Pythagoras ppt AB^2=10^2 +10^2

=100+100

=√200

=10√2
