Write the rational number 1.5 using quotients of the form p/q. Use the integers below.

Answer:

3.69

Step-by-step explanation:

2.4-9.1 = -6.7

-6.7+12.5x = 39.44

12.5x = 39.44 + 6.7

12.5x = 46.14

x = 46.14 / 12.5 = 3.69

Answer: x < 9

Step-by-step explanation: Actually, this is a LOT simpler than it seems.

So, looking at the problem, you know that the opposite value of x (opposite value is the number of spaces of a number away from 0), is less than 19 when you add it to 10. That said, |x| could be any rational number- whether positive or negative, as long as long as it equals less than 19 when added to 10. X could be -3, for example, because -3+10=7, which is <19. If, hypothetically, x were -3, then |x| would be 3, because -3 is 3 spaces from 0 (I just thought I'd explain it a little, because absolute value itself was confusing for me when I learned it at first).

Anyway, x could not be any number greater than 9 because than it would equal more than 19, and it can't be 9 because that wouldn't be less than 19. Does that make sense?

Answer:

Actually, it's C multiplication Cutty you can't be giving Wrong answers.

Step-by-step explanation:

It's C Multiplication because Were using the PEMDAS technique and this stands for

P- Parenthesis

E- Exponents

M- Multiplication

D- Division

A- Addition

S- Subtraction

So if you see in the Pemdas technique It will be C Multiplication.

Answer:

The rate of change is: as x increases by 10, y increases by 30. In other words, the rate of change is +30

Step-by-step explanation:

When calculating rate of change you see how much the y increases/decreases each time the x increases/decreases as we see, each time the x goes up by 10 the y goes up by 30.

Answer:

3x=15

Step-by-step explanation:

Here's what I found on google about the distributive property-

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Now for the math-

3(x+5)

distribute the numbers-  3(x)+3(5)

solve-  3*5=15

3x+15

5 is the y intercept.

-Always the number without the variable.

Given:

The system of equations is

[tex]x+3y=42[/tex]       ...(i)

[tex]2x-y=14[/tex]        ...(ii)

To find:

The number that must be multiplied with the second equation to eliminate the y-variable.

Solution:

Coefficient of y variable in equation (i) is 3 and in equation (ii) is -1.

To eliminate y-variable the absolute value of coefficients of y-variables should be same.

So, we need to multiply the second equation by 3 to eliminate the y-variable

Multiplying equation (ii) by 3, we get

[tex]6x-3y=42[/tex]      ...(iii)

Adding (i) and (iii), we get

[tex]x+3y+6x-3y=42+42[/tex]

[tex]7x=84[/tex]

Divide both sides by 7.

[tex]x=12[/tex]

Put x=12 in (i).

[tex]12+3y=42[/tex]

[tex]3y=42-12[/tex]

[tex]3y=30[/tex]

Divide both sides by 10.

[tex]y=10[/tex]

Therefore, x=12 and y=10.

Answer:

Multiply the second equation by 3. The solution is x = 12, y = 10.

Answer:

1.175 Canadian dollars

Step-by-step explanation:

129.6/5.50 = 27.70/x

because the exchange ratio is the same for the two currencies, use the above equation to find the answer. Therefore, use the cross multiply system which gets you

152.23 = 129.6x

x = 1.175

Step-by-step explanation:

The decimal number 5.25 is equal to the fraction 21/4.

Answer:

y=-2x+19

Step-by-step explanation:

For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form:  m= [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].

Now we have,

m= 3-7/8-6

m=-2. Since m=-2, the equation is y=-2x+b.

To find b, think about what your (x,y) points mean:

(6,7). When x of the line is 6, y of the line must be 7.

(8,3). When x of the line is 8, y of the line must be 3.

Substitute them to the equation  y=-2x+b.

You can use either (x,y) point you want..the answer will be the same:

(6,7). y=mx+b or 7=-2 × 6+b, or solving for b: b=7-(-2)(6). b=19.

(8,3). y=mx+b or 3=-2 × 8+b, or solving for b: b=3-(-2)(8). b=19.

So, the equation of the line that passes through the points

(6,7) and (8,3)  is  y=-2x+19.

Answer:

20

Step-by-step explanation:

because if you find oh nvm you know what a common factor is

Answer:

C, 20

Step-by-step explanation:

The answer is 20 because the multiple of a number can not be less than the number itself so we can cross out the option 2 and 4 because they are both less than 10. We can then check if 20 and 40 fit the requirements of being a multiple of both 10 and 4. They both fit but it asks for the LEAST common multiple and because 20 is smaller than 40, we can find our answer to be C, 20.

Answer:

$2.69

Step-by-step explanation:

here is with distribution...

1. add all the original prices together

2.50+4.95+6.00=13.45

2. multiply that sum(13.45) by 0.2(0.2 IS THE 20% OFF)

13.45x0.2=2.69

FINAL ANSWER: $2.69

Answer:

Subtract 10 from both sides of the equation. The equation in standard form is:

y = [tex]7m^{2}[/tex] + 3m + 1

Step-by-step explanation:

To convert [tex]7m^{2}[/tex] + 3m + 11 = 10 into standard form ( y = ax^2 + bx + c), subtract 10 from both sides of the equation to make the equation equal to zero:

[tex]7m^{2}[/tex] + 3m + 11 = 10

[tex]7m^{2}[/tex] + 3m + 11 - 10 = 10 - 10

[tex]7m^{2}[/tex] + 3m + 1 = 0

Replace the 0 with y and you have your answer :)

Answer:

0

Step-by-step explanation:

Using the cofunction identity

sin x = cos(90 - x), then

cos²31° - sin²59°

= sin²(90 - 31)° - sin²59°

= sin²59° - sin²59°

= 0

Answer:

Prob 150

Step-by-step explanation:

Answer:

angle 1 =135

Step-by-step explanation:

it is 180 degrees total. We know that there are two angles that have a ratio to 3:1. So, assign x to 2. Since 1 = 3x, we do 3x+x =180

4x=180

x=45 or angle 2

180-45=135 or angle 1

Multiply angle 2 by 3 to check if its correct

Answer:

the measurement of angle 1 is 135 degrees. (i think)

Step-by-step explanation:

so we know that angle 1 and 2 are at a 3:1 ratio

and that 1 and 2 add to 180 degrees

if you plug the number 45 in to angle 1, then multiply that by 3 you get 135

the remaining number to add to 180 would be angle 2

which is 45 degrees.

If the explanation is choppy or hard to read, apologies, its fairly hard for me to explain this.

however i hope this helps.
