Answer:

fractions that are the same

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]

Answer:

4, -1/4

Step-by-step explanation:

I took the test 2021 on edge

The solution to this system of equations is (4, -1/4)

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

G = √m-5 /2

g² = m-5 /2

2 × g² = m - 5

2g² = m - 5

2g² + 5 = m

So, m = 2g² + 5

Answer:

m = 2G²+5

Step-by-step explanation:

G²= m-5/2

2g² = m-5

2g² +5 = m

m = 2G²+5

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.

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%.

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:

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
