Answer:
x = -20
y = -62
Step-by-step explanation:
Suppose x and y two number and such that :
- their sum = -102
- and y is 62 less than x
Which means :
then
then
x + y = (y+62) + y = -102
then
2y + 62 = -102
then
2y = -164
then
y = -164/2 = -82
therefore
x = y + 62 = -82 + 62 = -20
Answer:
119/100 = 357/X
Step-by-step explanation:
since 357 is the price with the extra 19% tax, you can put 119 and 357 as numerators in a fraction because thats the price % of total cost with the tax, then have the denominators as the normal price without tax. so 119/100 bc 119 is the total cost % with tax, and 100 as the normal cost %. same for the opposite side, 357/X. 357 being the price with the tax and X being the price without the tax. so you just cross multiply to find X. so 100 × 357 (35,700) then divide the answer of that by 119 (35,700/119) to find X (300)
Answer:
circumference=2πr=75
2×3.14×r=75
6.28 r=75
r=75/6.28=11.943=12 inch (nearly)
Step-by-step explanation:
H=v/(2pir)
You just have to isolate h. To do that you are going to divide both sides by 2pir.
