3x-5y=-3 original problem
3(1)-5y=-3 put 1 in the place of x and multiply
3-5y=-3 subtract 3 from both sides
-5y=-6 divide both sides by -5
y=possitive 6/5
hope that helps
Answer:
The answer is below
Step-by-step explanation:
The compound interest is given by the formula:
Where A is the final amount, p is the principal (initial amount), r is the rate, t is the number of period and n is the number of times it was compounded per period.
Given that:
The interest is compounded yearly, i.e n = 1, for 1 year, t = 1, the compound interest is Rs 450 i.e A = 450. Therefore:
For 2 year, t = 2, the compound interest is Rs 945 i.e A = 945. Therefore:
Dividing equation 2 by equation 1 gives:
2.1 = 1 + r
r = 2.1 - 1 = 1.1
r = 1.1
Put r = 1.1 in 450 = P(1 + r)
450 = P(1 + 1.1)
450 = 1.11P
P = 405.4
Therefore the rate is 1.1 = 110% and P = Rs 405.4
Answer:
escalator?
Step-by-step explanation:
An escalator begins at 7.6 feet and increases steadily at 0.2 feet. You could then determine how high the escalator is after so many seconds(x), as well as how long it would take to get to a certian height (y).

Answer:
36
Step-by-step explanation:
The 5 part of the ratio represents 60 girls.
Divide 60 by 5 to find the value of one part of the ratio
60 ÷ 5 = 12 ← value of 1 part of the ratio
The 3 part of the ratio represents the number of boys, hence
3 × 12 = 36 ← number of boys
