Answer:

Sum- 17 Difference- 7.6

Papessa [141]4 years ago

Answer:

To find the estimated sum, round the 2 integers to the nearest whole number.

12.3----->12

4.7------->5

we round 12.3 to 12 because whenever we're asked to round a number, we always look to the digit to the right of the number, if the digit on the right is greater than or equal to 5, we round up if it's less that 5, we round down.

12+5=17

12.3-4.7

we already rounded 12.3 to 12 and 4.7 to 5 so now

12-5=7

Hope this helps

What are all the fractions that are between 1/2 and 1.
Oksanka [162]

Answer:

2/4, 3/5,3/4, 2/3,13/25, 27/50 11/20, 14/25, 29/50,31/50, 63/100,16/25,33/50,17/25,7/10,18/25,37/50,19/25,77/100,39/50,4/541/50, 83/100, 21/25 , 17/20, 43/50 , 87/100,22/25,9/10, 91/100, 23/25, 93/100, 47/50, 19/20 , 24/25  97/100, 49/50,99/100(note that I did not state all the fractions between 1/2 and 1)

Step-by-step explanation:

Firstly one half(1/2) represents 0.50 as a decimal and 1 would be 1.00

This is like saying finding Fractions that give you percentages between 50% and 100%

for example:

you could simplify 52/100 and get 31/50

31/50 as a decimal would be 0.52  and 0.52 falls between(0.50 and 1.00) 1/2 and 1

example 2: 89/100= 0.9 (same as0.90) and [90/100] is same as 9/10 = 0.9

0.90 or 0.9 (zero point nine) is not the same as 0.09(zero point zero nine

If you are using a casio calculator, you can simplify the fraction by putting in your numerator then pressing |a b/c| button then enter the denominator, then the calculator should simplify the fraction, if the fraction remains the same, this means that it cant be further simplified.if your calculator has

| a b/c| then you can also use it.

or use an online calculator or simplify if you wish

To <em>find the decimal of that fraction you can simply divide the numerator by the denominator, Example; 82/100 is same as 0.82 and 41/50 is same as 0.82.</em>

What is an equation of the line that passes through the points (-1, -6) and (6, 1)?
Agata [3.3K]

Answer:

Step-by-step explanation:

It is vital  to first find the gradient/ slope between the points

m=\frac{y2-y1}{x2-x1} \\=\frac{1-(-6)}{6-(-1})\\ \\m=1

let us use the point (6,1) to find the value of c

y=mx+c

1=1(6)+c

1-6=c

∴c=-5

the equation is given by

y=x-5
