C = 5/9 (F - 32)
F = (9/5)C + 32
F = (9/5)(-40) + 32 = -40
F = (9/5)(125) + 32 = 257
<span>Being able to express numbers in its equivalent forms allows you to give more accurate and correct answers. By using equivalents forms you may find a simply and easier way to solve the given equation.
For example, in fraction, by simply expressing equivalent fractions with common denominator, you can easily subtract and add the given numbers in an easy way. There are a lot of numbers that are equivalent, and there are a lot of way to solve a single problem to get a correct answer.</span>

c
Step-by-step explanation:
Jessica planted a rosebush in her garden. The rosebush has a height of 30 cm. Each month the rosebush increases by 6 cm. Which equation can be used to determine the height of the plant in centimetres, y, after x months?
the rate of increase of the bush every month is 6 cm
Rate of increase of the bush in x months = 6x
because the bush increases every month, 6x would be added to 30cm
y = 6x + 30
If the bush decreased at a rate of 6cm every month, the equation would be y = 30 - 6x
Answer:
hello :
note : 1²+2²+3²+........+n² = n(n+1)(n+2)/6
Step-by-step explanation:
let : S = 1²+2²+3²+......+25²
A = 16²+17²+18²+...+25²
B = 1²+2²+3²+......+15²
S = (1²+2²+3²+....+15²) + (16²+17²+18²+...+25²)
calculate : S for : n = 25
S = 25(26)(27)/6 = 2925
calculate : B for : n = 15
B = 15(16)(17)/6 = 680
so : S = B + A
A = S - B = 2925 - 680 = 2245
