Answer:
x = 19
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180 degrees
3x + 7 + 5x + x + 2 = 180 add like terms
9x + 9 = 180 subtract 9 from both sides
9x = 171 divide both sides by 9
x = 19 replace x with 19 in expressions to find the angle measures
This is the concept of linear proportionality, the linear scale factor of the polygon given will be:
[perimeter of larger polygon]/[perimeter of smaller polygon]=[length of larger polygon]/[length of smaller polygon]
=28/20
=7/5
thus the length of the larger polygon will be given by:
7/5=x/4
thus;
7/5*4
=5.6
thus the length 5.6
The answer is c as ((3)*2) + 5 = (11)
8) B - It's asking for the price you should offer, so you want to find 7% of the asking price (p) by multiplying it to 0.07 (which is 7%, move decimal to left 2 places). Then you want to subtract that number from the asking price to get the amount you should offer
9) C - It's asking for how much money you'll save, so you need to multiply how much computers you'll buy (25) to the price of each computer (z). Then you'll multiply that number to 0.19 (which is 19%, move decimal to left 2 places) to get how much you'll save
Answer:
-7 degrees
Step-by-step explanation:
-28 divided by 4 equals -7. -7 x 4 = -28
