The solution to this system of equations is (4, -1/4)
What are system of solutions?A collection of values for a variable that simultaneously fulfill each equation is the solution to a system of equations. A system of equations must be solved by identifying all possible sets of variable values that make up the system's solutions.
Given
[tex]\frac{1}{4} x + 1\frac{1}{2} y = \frac{5}{8} \\\frac{1}{4} x + \frac{3}{2} y = \frac{5}{8} \\\\\frac{x +6y}{4} =\frac{5}{8}\\ x+6y = \frac{5}{8} *4 = \frac{5}{2} \\[/tex]
[tex]2x +12y = 5 ........(i)\\\\\frac{3}{4} x - 1\frac{1}{2} y = 3\frac{3}{8} \\\\\frac{3}{4} x - \frac{3}{2} y = \frac{27}{8} \\\\\frac{3x -6y}{4} =\frac{27}{8}\\ 3x-6y = \frac{27}{8} *4 = \frac{27}{2}[/tex]
6x - 12y = 27...(ii)
Adding equation(i) and (ii),
2x + 6x = 5 + 27
=> 8x = 32
=> x = 4
Plug the value of x in equation(i),
2(4) + 12y = 5
8 + 12y = 5
=> 12y = 5 - 8 = -3
=> y = -1/4
Hence, the solution to this system of equations is (x, y) = 4,-1/4

Given that 3x – 8y = 39
Find y when x = 3
Give your answer as an improper fraction in its simplest form.
Answer:
- [tex]\frac{15}{4}[/tex]
Step-by-step explanation:
Given
3x - 8y = 39 ← substitute x = 3 into the equation
3(3) - 8y = 39
9 - 8y = 39 ( subtract 9 from both sides )
- 8y = 30 ( divide both sides by - 8 )
y = [tex]\frac{30}{-8}[/tex] = - [tex]\frac{15}{4}[/tex]

Bill wants to increase 150 by 3%
He writes down
150 X 1.3 = 195
Bill's method is wrong.
(a) Explain why.
+
Answer:
//
Step-by-step explanation:
Bill's answer is wrong because timesing 150 by 1.3 is increasing the number by 30%, not 3%
If he wanted to use this method, he would have ti times 150 by 1.03
Bill's method is wrong because 150 by 1.3 is increasing the number by 30%, not 3%.
What is the formula for calculating the increase?The formula for calculating the increase is:
original amount × (1 + percentage increase)
Bill wants to increase 150 by 3%
He writes down :
150 × 1.3 = 195
Bill's method is wrong because he is using the wrong formula to calculate the increase. To calculate the increase, you need to multiply the original amount by the percentage increase, not add the percentage increase to the original amount.
To calculate a 3% increase on 150, the correct method is:
150 × (1 + 0.03) = 150 × 1.03 = 154.50
As you can see, the result is different from the one that Bill obtained using his method.
Hence, Bill's method is wrong.

Answer:
2) 224πcm²
3)156 cm²
??? what would this beee!!!
Answer:
110 on the left and 70 on the right
(you can use the f rule )
Answer:
the unknown angle on the left (below 110°) is also 110°
the unknown angle on the right is 70°
Step-by-step explanation:
this is because the lines are parallel, and when they're intersected by the same line respective angles on each line are equal.
On the top line, the top left angle is 110° and so the top left angle on the bottom line is 110° too. Same goes for the other angle.

Step-by-step explanation:
Please help im so stuck on this !!!!!!!!n
Answer:
Step-by-step explanation:
4) d = 12 cm; r = 12/2 = 6cm ; h = 5 cm
S.A = 2πr(r + h)
= 2* 3.14 * 6 * (6 + 5)
= 2 * 3.14 * 6 *11
= 414.48 cm²
5) d = 8 cm ; r = 8/2 = 4cm ; h = 7cm
S.A = 2πr(r + h)
= 2 *3.14 * 4 * (4 + 7)
= 2 * 3.14 * 4 * 11
= 276.32 cm²
6) r = 4 cm ; h = 6cm
SA = 2πr(r +h)
= 2 * 3.14 * 4 * 10
= 251.2 cm²
7) Area of front and back = [tex]2*\frac{1}{2}*base * height[/tex]
= base * height
SA = (front and back) + Base + left + right
= 4* 3 + (8*3) + (8*4) + ( 8*5)
= 12 + 24 + 32 + 40
= 108 cm²
8) SA = (front and back) + Base + left + right
= (8 * 6) + (12*6) + (12*8) + (12*10)
= 48 + 72 + 96 + 120
= 336 cm²
9) SA = (front and back) + Base + left + right
= (12 *5) + (8*5) + (8*12) +(8*13)
= 60 + 40 + 96 + 104
= 300 cm²

Adam purchased some items at the school store. He bought 3 pencils for $0.15 each and 5 single-subject notebook
If these items cost a total of $6.45, what was the cost of each notebook?
O A. $1.20
B. $1.26
O c. $1.29
OD. $1.38
Answer:
The answer is A
Step-by-step explanation:
Fist multiply 3 and .15 to get .45 for 3 pencils. Then subtract .45 from 6.45 and get 6. Then divided 6 by 5 to get 1.2 for each book
i think the answer is a: $1.20
my work:
3 x 0.15 = 0.45.
6.45 - 0.45 = 6.00
6.00 / 5 = 1.20
and i checked my work by doing 1.20 x 5 + 0.40 = $6.45.
