Answer:
5
Step-by-step explanation:
W = x
L = x + 3
P = 2W + 2L
26 = 2(x) + 2(x + 3)
26 = 2x + 2x + 6
26 = 4x + 6
26 - 6 = 4x
20 = 4x
x = 5
The perimeter of a triangle is 17x−5 units. One side is 3x+5 units and another is 8x−3 units. How many units long is the third side?
9514 1404 393
Answer:
6x -7 units
Step-by-step explanation:
Let c represent the length of the third side. The perimeter is the sum of the three side lengths.
P = a + b + c
(17x -5) = (3x +5) +(8x -3) +c
17x -5 = 11x +2 + c . . . . . . . . . . . . collect terms
6x -7 = c . . . . . . . . . . . . . . subtract 11x+2
The third side is 6x -7 units.
If I roll 2 dice, what is the
probability that their total is a
prime number?
Answer:
The logic is there are six sides to each die, so for each number on one die you can pair with six different numbers on the other die. Therefore, the probability of rolling a prime number on two dice is 15/36, which reduces to 5/12
Choose the correct description of each system of equations.
3x + y = 3
x - 2y = 4
Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.
Given the system of equation expressed as:
3x + y = 3
x - 2y = 4
Solve simultaneosly;
3x + y = 3 ............. 1 * 1
x - 2y = 4 ...............2 * 3
_________________________
3x + y = 3
3x - 6y = 12
Subtract
y-(6y) = 3 - 12
7y = -9
y = -9/7
Substitute y = -9/7 into the equation to get x
x - 2y = 4
x - 2(-9/7) = 4
x + 18/7 = 4
x = 4 - 18/7
x = 3/7
Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.

Answer:a 750g bag is better.
Step-by-step explanation: 3 bags would be more G the 2kg and less money 0.23/100 grams 700 g would be 1.4$ for that so 750 g is the best.
Answer:
750 grams at $1.39
Step-by-step explanation:
To make it easy to see, determine how much each option costs per gram.
750 grams cost 1.39. Divide 1.39 by 750 which gives you 0.001853
2 kg is 2000 grams costing 3.99. Divide 3.99 by 2000 which give you 0.001995
100 grams cost $0.23. Divide 0.23 by 100 which gives you 0.0023
So the 750 grams is the best price.

Which graph represents the solution to the inequality? 4v - 2 < 10
Answer:
Option C.
Step-by-step explanation:
First, simplify the inequality. Add 2 to both sides:
4v - 2 < 10
4v - 2 + 2 < 10 + 2
4x < 12
Divide both sides by 4:
4x ÷ 4 < 12 ÷ 4
x < 3
As 3 will not satisfy the inequality, it is not a solution. The option that shows x being less than 3 but not including is option C.

It's 5 if: (please confirm before you answer it--the picture is blurry and it's hard to tell).
The line appears to intersect the origin (0,0) and (2.5,12.5).
Slope is rise over run, so if you take the difference in y value and divide it by the difference in x value, you get the slope.

Answer:
1) 350
2) 195.83
Step-by-step explanation:
#1.Tuition fee = $12, 000 per year.
30% of it's being paid off by the scholarship, so she'll have to pay:
[tex] = 12000 - ( \frac{30}{100} \times 12000) [/tex]
[tex] = 12000 - 3600[/tex]
[tex] = 8400[/tex]
She'll have to pay $ 8400 by herself, her savings.
If she's saving $ 8400 for two years, she's actually saving $ 8400 for 24 months!
for one month, it'll be
= 8400/ 24
= $ 350 per month
#2one year fee = $ 10, 700
uncle pays half of it, I.e., 10700/ 2
= $ 5, 350
he gets a grant for $ 3,000
so, the part of the fee he ain't paying
= 5,350 + 3000
= $ 8,350
So, he'll have to save:
= 10,700 - 8,350
= $ 2,350
that is per year,
for per month = 2350/ 12
= $ 195.83
