Let’s say the number is “n”

First it’s telling u twice a number meaning the number is going to multiply by 2 so

2 X n (X means multiplication) or 2n

Then it states five more than which means to add 5 to what follows so

2n + 5

It’s saying it’s 7 so

2n+5=7
2n= 7-5
2n=2
2n/2=2/2
N=1

The final answer is 1 meaning the number is 1

Car A travels at 35 miles per hour and Car B travels at a greater speed of x miles per hour. Choose the expression that represen
Rina8888 [55]

Answer:

-2x+25 D

Step-by-step explanation:

To determine how far it will go in an unspecified number of hours, we can let t = time in hours. The letter t will be our variable. Assuming that the car travels at the same speed, we can state that the rate is 55, and that will be our constant. The expression would then be:

Distance of car traveled in t hours, which we can denote as D(t) = 55 x t = 55t

This means that D is a function of t, and D represents the total distance traveled in t hours.

PLEASE HELP ASAP, I WILL GIVE 40 POINTS IF THE RIGHT ANSWER, AND BRAINLEST, ASAP
Lilit [14]

Answer:

We multiply by 2 and add 4

Step-by-step explanation:

To find the pattern,  we find the slope

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

m = ( 10-6)/(3-1)

m = 4/2

m =2

We are multiplying by 2

y = mx+b  where m is the slope and b is the y intercept

y = 2x+b

Using the point (1,6)

6 = 2(1)+b

6 = 2+b

The y intercept is 4

y = 2x+4

We multiply by 2 and add 4
