Answer:
21/8
Step-by-step explanation:
Simplify the following:
6 + 1/4 - (3 + 5/8)
Put 3 + 5/8 over the common denominator 8. 3 + 5/8 = (8×3)/8 + 5/8:
6 + 1/4 - (8×3)/8 + 5/8
8×3 = 24:
6 + 1/4 - (24/8 + 5/8)
24/8 + 5/8 = (24 + 5)/8:
6 + 1/4 - (24 + 5)/8
24 + 5 = 29:
6 + 1/4 - 29/8
Put 6 + 1/4 - 29/8 over the common denominator 8. 6 + 1/4 - 29/8 = (8×6)/8 + 2/8 - 29/8:
(8×6)/8 + 2/8 - 29/8
8×6 = 48:
48/8 + 2/8 - 29/8
48/8 + 2/8 - 29/8 = (48 + 2 - 29)/8:
(48 + 2 - 29)/8

Answer: 21/8
Answer:
Its B
Step-by-step explanation:
the y interceot is +10 so it is positie 10 and the slope is -4 so it is negative 4
Answer:
The answer is

Step-by-step explanation:
To find an equation of a line given the slope and a point we use the formula

where
m is the slope
( x1 , y1) is the point
From the question the point is (3, -10) and the slope 4
We have

We have the final answer as

Answer:
Let x be the number of silver medals.
As there were two more gold medals than silver ones, gold medals are x+2
We also know that the number of bronze medals was 4 less than the sum of gold and silver, so if there are x + 2 of gold and x of silver, there are x+x+2-4 of bronze.
Now, we can do an equation, as we know there were a total of 28 medals:
x + x + 2 + x + x + 2 - 4 = 28
And we isolate x:
4x = 28
x = 28/4 = 7
There were 7 silver medals, so there were 9 gold ones (7-2) and 12 of bronze (9+7-4).
Answer:
x = 1 − √63i / 4 , x = 1 + √63i / 4
Step-by-step explanation:
Let's use the formula −b±√b2−(4ac) / 2⋅a
= ax^2+bx+c=0
= 2x^2-x+8=0
Let's substitute 2 for a, −1 for b, and 8 for c in the formula of quadratic equation.
x = −1±√−12−(4⋅2⋅8) / 2⋅2
x = 1±√1−64 / 4
x = 1±√−63 / 4
x = 1±√63⋅−1 / 4
x = 1±√63√−1 / 4
x = {1−√63i / 4 , 1±√63i / 4}
