Step-by-step explanation:

Let n be the number of days he has been doing sit ups, not counting the first day. Since he does 2 more sit-ups for each day, then the number of additional sit-ups is 2n.

Since he started doing  15 sit-ups on the first day, the total number of sit-ups

after x days would be 2n+15.

Since he did a total of 33 sit ups today, then 2n+15=33

What is the measure of angle x?

Answers

The sum of all angles of a triangle = 180.
So 180-90 (right angle) - 51 (other known angle) = 39
the measure of angle x would be 39°
triangles only go up to 180° and that triangle already has a 90° right angle and a 51° acute angle. so the answer is 39°

Answer:

4x^2+3x+y^2+30y+8

Step-by-step explanation:

given expression:

x^3+x(4x - x^2) + 3y^2 +12 - 4x^0 +2y(15 - y) + 3x

expand the terms we get:

x^3 + 4x^2 - x^3 + 3y^2 + 12 - 4 +30y - 2y^2 + 3x

bring all like terms together we get:

x^3 - x^3 + 4x^2 +3x + 3y^2 -2y^2 + 30y + 8

= 4x^2 + 3x + y^2 +30y + 8

20% - $117.76 = $16.62
and how dose it work?

Answers

Answer:

0.20 - $117.76= $16.62

Step-by-step explanation:

if you  have a percentage you can always turn it into a decimal just put the number behind the period: 70% = .70, 49% = .49%       ....

then you do the rest of the equation and BOOM!

20% - $117.76 = $16.62 = 0.20 - $117.76= $16.62.

Answer:

Answer is below

Step-by-step explanation:

20% - $117.76 = $16.62 = 0.20 - $117.76 = $16.62.

or

20 x 100 / 100 - $117.76 = $16.62
