Answer:
4 2/7 - 6/7 = 24/
7
= 3 3/
7
Step-by-step explanation:
Conversion a mixed number 4 2/
7
to a improper fraction: 4 2/7 = 4 2/
7
= 4 · 7 + 2/
7
= 28 + 2/
7
= 30/
7
To find a new numerator:
a) Multiply the whole number 4 by the denominator 7. Whole number 4 equally 4 * 7/
7
= 28/
7
b) Add the answer from previous step 28 to the numerator 2. New numerator is 28 + 2 = 30
c) Write a previous answer (new numerator 30) over the denominator 7.
Four and two sevenths is thirty sevenths
Subtract: 30/
7
- 6/
7
= 30 - 6/
7
= 24/
7
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(7, 7) = 7. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 7 × 7 = 49. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - thirty sevenths minus six sevenths = twenty-four sevenths.
We have three pairs of rectangles:
16ft × 6ft = 96ft²
2ft × 6ft = 12ft²
2ft × 16ft = 32ft²
S.A. = 2 × (96 + 12 + 32) = 2 × 140 = 280ft².
<h3>Answer: C.) 280ft²</h3>
Answer:
x = 0
y = 2
Step-by-step explanation:
3x + 9y = 18 ---------eqn 1
y = x + 2---------eqn 2
Substitute eqn 2 into eqn 1, for the value of y
3x + 9( x + 2) = 18
3x + 9x + 18 = 18
12x + 18 = 18
12x = 18 -18
12x = 0
Divide both sides by 12 , to get the value of x.
12x/ 12 = 0/12
x = 0
Substitute x = 0 into eqn 2
y = x + 2
y = 0 +2
y = 2
Hint: to confirm the values
x = 0
y = 2
Let's take eqn 1 ,
3x + 9y = 18
3(0) + 9(2)
= 0 + 18
= 18
Correct
Let's take eqn 2
y = x + 2
Let's find y
y = 0 + 2
y = 2
Correct too
The answer to these 2 questions would be:
1.
.8 is greater than .7.
or.
.7 is less than .8.
Why?
.8 is .1 higher than .7.
.7 + .1 = .8, so the greater than would be placed facing the .8.
2.
.8 is less than 7.
or.
7. is greater than .8.
Why?
You see where the decimal is placed at? It is placed after the 7 which makes the 7. a whole number. While .8 is still a decimal, 7. is way higher than .8 because of where the decimal is at.
This is how we get both our answers, 1. .8 and 2. 7.
Hope this helps!~
meaning that (-3,-3)
meaning that (5,4)
(1 ) Find slope.
The slope is 7/8
(2) Substitute any ordered pairs in the equation.
I'll use (5,4)
Therefore the equation for f(x) is
