Answer:

32/60 and 33/60

Step-by-step explanation:

Common Denominator is 60.

8x4=32

15x4=60

8/15= 32/60

11x3=33

20x3=60

11/20= 33/60

Answer:

Solving this simultaneous equation by using substitution method 3x-2y=12 and x+3y=-7 ​we get x=2 and y=-3

Solution set = {2,-3}

Step-by-step explanation:

We need to solve this simultaneous equation by using substitution method 3x-2y=12 and x+3y=-7 ​

let:

[tex]3x-2y=12--eq(1)\\x+3y=-7 --eq(2)[/tex]

Finding value of x from equation 2 and putting in eq(1)

[tex]From \ eq(2)\\x+3y=-7\\x=-7-3y[/tex]

Putting value of x in eq(1)

[tex]3x-2y=12\\Put \ x=-7-3y\\3(-7-3y)-2y=12\\Solving\\-21-9y-2y=12\\-11y=12+21\\-11y=33\\y=\frac{33}{-11}\\y=-3[/tex]

So, we get y=-3

Now put value of y in equation 2 to find value of x

[tex]x+3y=-7\\x+3(-3)=-7\\x-9=-7\\x=-7+9\\x=2[/tex]

So, we get value of x =2

So, solving this simultaneous equation by using substitution method 3x-2y=12 and x+3y=-7 ​we get x=2 and y=-3

Solution set = {2,-3}

Step-by-step explanation:

Answer:

A, D, and F

Step-by-step explanation:

Tiara did multiply and regroup correctly in the first partial product. Tiara did not multiply and regroup correctly in the second partial product. Tiara was not correct when she added her 2 partial products.

Tiara should of got 18,291 but instead she got 16,291.

When she went to the part to multiply 3x4 she didn't add the remaining 2 from the 3x6+2. So if she did 3x4+2 she would of got the number 14 instead of 12 to put down in the second partial product. Which would make the addition part of it as 4,221 + 14070 = 8291 instead of 4,221 + 12,071 = 16, 291

I hope you understand :)

Answer:

8/7

Step-by-step explanation:

first set = 5/7

second set = 3/7

3/7+5/7=8/7

Answer:

Step-by-step explanation:

[tex]2z - 1 = - 15[/tex]

Move -1 to the right side of the equation

[tex]2z = - 15 + 1 \\ 2z = - 14[/tex]

Divide both sides by 2

[tex] \frac{2z}{2} = - \frac{14}{2} \\ [/tex]

We have the final answer as

Hope this helps you

Answer:

1/8 mile

Step-by-step explanation:

This is a subtraction problem. We need to subtract 5/8 from 3/4. We need a common denominator of 8.

3/4 - 5/8 = 6/8 - 5/8 = 1/8

Answer: 1/8

Answer:

Malika runs 1/8 of a mile more than Andrew

Step-by-step explanation:

The easiest way to figure this out is by converting both of the fractions to have the same denominator. Do not convert them to decimals because the answer might not always turn out to be right.

If we keep Andrew's distance of 5/8 the same we can easily convert Malika's distance of 3/4 to the same denominator by multiplying it by two

[tex]\frac{3}{4} *\frac{2}{2} = \frac{6}{8}[/tex]

Now that the denominators are the same, we are able to subtract the fractions.

[tex]\frac{6}{8} -\frac{5}{8} = \frac{1}{8}[/tex]

Malika runs 1/8 of a mile more than Andrew

Answer:

x = 33 (33.3)

Step-by-step explanation:

x/100 X 75 = 25

75x/100 = 25

75x = 2500

x = 33 (if rounded to the nearest whole number)

x = 33.3 (if rounded to the nearest tenth)
