X+x+x-15+x-15=98 simplifies to 4x-30=98 move the 30 over 4x=98+30 simplify and you have 4x=128 divide both sides by 4 and you're left with x=32 which is your length, your width is 32-15 which is 17.

Half of perimeter (or L+ W) is:
98/2= 49 (cm)

L- W= 15
L+ W= 49

L= (49+ 15)/2= 32
W= (49-15)/2= 17

The length is 32 cm and the width is 17 cm~

MATH HELP PLEASE WILL GIVE BRAINLIEST!!!
Maurinko [17]
Hello,

When we have a quadrilateral inscribed in a circle, the opposite angles add up to 180 degrees (supplementary).

Therefore, we can write and solve the following equation first with angles B and D.
3x + 9 + 2x - 4 = 180
5x + 5 = 180
5x =175
x = 35

Then, sub 35 in the expression for angle A and you will get:
2(35) + 3
70 + 3
73

Angle A is 73, that would make angle C equal to 107 degrees, because 180 - 73 = 107.

Good luck,

You have a coupon for an additional 25% off the price of any sell it item at a store the store has put a robotics kit on sale fo
aalyn [17]

Answer:

the kit costed $40 - $6 = $34 after the first general discount. Now the question is if the coupon relates to the original price or to the lowered price. We'll do both:

If it relates to the original price, we need to find how much is 25% of $40. We can do it in mind - it's $10. So with two discounts the price would be $40 - $6 - $10 = $24.

However, if it relates to the lowered price, we need to find how much is 25% from $34:

34 * 25% =

= 34 * 25/100 =

= 34 * 1/4 =

= 8.5 [dollars]

So the final price in such a situation would be $40 - $6 - $8.5 = $25.5

Can someone explain how to work this out please
valina [46]

Answer:

8/37

Step-by-step explanation:

First subtract 450 - 370.

450 - 370 = 80

Then put it into fraction form where the increase is the numerator and the cost from last year is the denominator.

80/370

Then, simply the fraction (if possible).

8/37
