The answer is 7.5.
7 4/8 is also 7.5
Answer:
Your annswer is b
Step-by-step explanation: because it is least than all of the others
2x-7y=18 _(1)
-2x+4y=5
11y=23 , Y=23/11 sub in 1
2x-7×23/11=18
2x = 18×11 + 7×23
x = ( 198 + 161 )/2 = 359/2
The simple interest formula allows us to calculate I, which is the interest earned or charged on a loan. According to this formula, the amount of interest is given by I = Prt, where P is the principal, r is the annual interest rate in decimal form, and t is the loan period expressed in years. The rate r must be converted from a percentage into decimal form.
Then, 2,000 = 1,000 * r * 10 ;
Finally, r = 2 ÷ 10 = 20 ÷ 100 = 0.2
hope this helps you
So area=1/2 base times height
50=1/2 base times height
multiply both sides by 2
100=base times height
base=4height
100=4height times height
100=4height^2
divide 4
25=height^2
squarer root
5=height
subisute
base=4(5)
base=20
height=5
