Answer:
x=1
y=-1
Step-by-step explanation:
x = y+2
x+2y = 5
y+2 +2y = 5
3y +2 = 5
3y = 3
y=1
x=-1
Answer:
Step-by-step explanation:
Insert y+2 into your x so...
y+2+2y=5
Then solve...
Combine like terms so 2y+y is 2y^2 (squared)
and..
5-2 is 3
you are left with 2y^2 (squared) = 3 is 0.75

Eliana needs 6 and 7/8 yards of wire.
She has 4 and 1/3 yards. How much more
wire does she need?
Answer:
she need 2 13/24 yards of wire
Step-by-step explanation:
4 1/3 and 6 7/8
times the 4 1/3 by 8 for a common denominator of 24.
which gives you 4 8/24
times the 6 7/8 by 3 for denominator of 24.
so 6 21/24 subtract the 21 and 8 for 13, common denominator and then 6 minus 4.
2 13/24 yards
Answer:
2 and 13/24
Step-by-step explanation:
First, figure out what you need: the difference between 6 7/8 and 4 1/3 in this case
Next, set up your equation:
6 7/8 – 4 1/3
To make the subtraction of fractions easier, turn both into improper fractions by multiplying the whole number (e.g. 6) with the denominator (e.g. 8) and then adding the numerator (e.g. 7):
6 7/8 = 55/8
4 1/3 = 13/3
To subtract these, they need to have the same denominator. By finding the lowest common multiple for 3 and 8 (the denominators) we can produce equivalent fractions with the same denominator.
LCM of 3 and 8 = 24
(55/8)*(3/3) = 165/24
(13/3)*(8/8) = 104/24
Rewrite the equation with the equivalent fractions: 165/24 – 104/24
Now subtract the numerators: 165 – 104 = 61, so the answer is 61/24
This can't be reduced further, so we turn it back into a proper fraction (by dividing the numerator by the denominator): 2 13/24
Therefore, Eliana needs 2 and 13/24 more yards of wire
a box has a volume of 56 cubic inches, and the base of the box is 4 inches by 4 inches. how many half inch cubes can fit in the box?
Answer:
448 half inch cubes can fit in the box.
Step-by-step explanation:
A box is represented by a parallelepiped, whose volume ([tex]V[/tex]), measured in cubic inches, is represented by the following formula:
[tex]V = w\cdot h\cdot l[/tex] (1)
Where:
[tex]w[/tex] - Width, measured in inches.
[tex]h[/tex] - Height, measured in inches.
[tex]l[/tex] - Length, measured in inches.
If we know that [tex]w = 4\,in[/tex], [tex]l = 4\,in[/tex] and [tex]V = 56\,in^{3}[/tex], then the height of the box is:
[tex]h = \frac{V}{w\cdot l}[/tex]
[tex]h = \frac{56\,in^{3}}{(4\,in)\cdot (4\,in)}[/tex]
[tex]h = 3.5\,in[/tex]
Given that box must be fitted by half inch cubes, the number of cubes per stage is:
[tex]x_{S} = \frac{(4\,in)\cdot (4\,in)}{(0.5\,in)\cdot (0.5\,in)}[/tex]
[tex]x_{S} = 64[/tex]
The number of stages within the parallelepiped is:
[tex]x_{N} = \frac{3.5\,in}{0.5\,in}[/tex]
[tex]x_{N} = 7[/tex]
The total quantity of half inch cubes that can fit in the box is:
[tex]n = x_{S}\cdot x_{N}[/tex]
[tex]n = (64)\cdot (7)[/tex]
[tex]n = 448[/tex]
448 half inch cubes can fit in the box.

Prove that:
7^16+7^
14 is divisible by 50.
Answer:
See Explanation
Answer: [tex] \boxed{ {7}^{14}} .50[/tex]
Step-by-step explanation:
[tex]{7}^{16} + {7}^{14} \\ \\ = {7}^{14} ( {7}^{2} + 1) \\ \\ = {7}^{14} (49 + 1) \\ \\ = {7}^{14}.50[/tex]
Since, one factor of [tex] {7}^{16}+ {7}^{14}[/tex] is 50.
Therefore, [tex] {7}^{16}+ {7}^{14}[/tex] is divisible by 50.
Hence proved.
In an examination, Suresh scored 89% marks out of 750 marks. How many marks
did he get?
Answer:
606.75
Step-by-step explanation:
10% = 75
20% = 150
40% = 300
80% = 600
if we know that 10% is 75, then 1% is 0.75
(75 divided by 10)
0.75 x 9 = 6.75
80 % as mentioned is 600
9 % is 6.75
600 + 6.75 = 606.75
so she got 606.75
David is playing basketball and makes 3 of his 5 shots. What is the experimental probability he will make his next shot?
Answer:
We have to divide 3/5 which is 0.6 or 60% chance
Step-by-step explanation:
Answer:
60%
Step-by-step explanation:
First you put into fraction form. 3 out of the 5 shots is 3/5.
Now you divide 3 by 5 to get 0.6
then you would multiply 0.6 by 100 to get 60 and that would be your percentage.
