Answer:

D. 10

Step-by-step explanation:

Since you divided by 2. You want to multiply to go back wards.

35×2=70

They already give you base(b=7) so to find the height you need to divide to go backwards since you multipled bh.

70÷7=10

now plug it in to see if the equation is right.

35= 1÷2 (7×10)

Find the common difference for the infinite arithmetic sequence shown.

mihalych1998 [28]

The common difference is 12

Further explanation:

It is given that the infinite sequence is an arithmetic sequence

The common difference is the difference between consecutive terms of an arithmetic sequence.

Here,

$a_1 = 211\\a_2 = 223\\a_3 = 235\\a_4 = 247........$

The common difference is denoted by d.

Here,

$d = a_2-a_1 = 223-211 = 12\\a_3-a_2 = 235-223 = 12$

The common difference is same for all proceeding terms.

So,

d = 12

ALGEBRA EQUATION PLEASE HELP ASAP -3=12y-5(2y-7)

Dovator [93]

Simplify:

−3=12y−5(2y−7)

−3=12y+(−5)(2y)+(−5)(−7)(Distribute)

−3=12y+−10y+35

−3=(12y+−10y)+(35)(Combine Like Terms)

−3=2y+35

Flip the equation.

2y+35=−3

Subtract 35 from both sides.

2y+35−35=−3−35

2y=−38

Divide both sides by 2.

2y/2=−38/2

y=−19

A car dealership increased the price of a certain car by 13%. The original price was $47400 what is the new price?

garik1379 [7]

Answer:

Step-by-step explanation:

To get the new price of the car multiply the original price by the percent increase in decimal form +1. 11% in decimal form is 0.11 = 11/100. Add one to this and you get 1.11 = 1 + 0.11. So now multiply $49,800 * 1.11 = $55,278. If the problem had said they decreased the price by 11% you would use 1 - 0.11 = 0.89 because 89% is 11% less than 100%.

hope that helps my man
