Can somebody help? I can’t figure it out.

Answer:

15 days

Step-by-step explanation:

a) Li uses = 8.4 grams of sugar every day in her tea.

Li’s sugar canister contains = 128 grams of sugar

Let x be the number of days at which Li uses sugar in her tea

The Equation for Li's sugar usuage =

y = 128 - 8.4x ......... Equation 1

Where y , the quantity of sugar left.

b) Sue uses = 12.6 grams of sugar every day in her coffee.

Sue’s canister contains = 191 grams

Let x be the number of days at which Sue uses sugar in her tea

The Equation for Sue's sugar usuage =

y = 191 - 12.6x .........Equation 2

Where y , the quantity of sugar left.

We are asked in the question, how many days will Li and Sue have the same amount of sugar in their canisters

We would equate both equations to each other.

Equation 1 = Equation 2

y = 128 - 8.4x = y = 191 - 12.6x

128 - 8.4x = 191 - 12.6x

-8.4x + 12.6x = 191 - 128

4.2x = 63

x = 63/4.2

x = 15

15 days

Therefore Li and Sue have the same amount of sugar in their canisters after 15 days.

To confirm

Equation 1 = Equation 2

y = 128 - 8.4x = y = 196 - 12.6 × 15

y = 128 - 8.4 × 15 = y = 196 - 12.6 × 15

y = 128 - 126 = y = 196 - 189

y = 2 = y = 2

Answer: 1/3

Step-by-step explanation:

Answer:

8 or 32

Step-by-step explanation:

So we are given two coordinates and the length of the segment formed by those coordinates.

To find the unknown coordinate, we can use the distance formula. Let the unknown value be n:

Let's let (-2,n) be x₁ and y₁ and let (-7,20) be x₂ and y₂.

The distance formula is given by the formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Substitute (-2,n) for x₁ and y₁ and (-7,20) for x₂ and y₂. Also, since we already know that the length is 13, substitute it for d. Thus:

[tex](13)=\sqrt{((-7)-(-2))^2+((20)-(n))^2}[/tex]

Do the operations within the parentheses:

[tex]13=\sqrt{(-7+2)^2+(20-n)^2}\\13=\sqrt{(-5)^2+(20-n)^2}[/tex]

Now, square both sides to take out the square root:

[tex](13)^2=(\sqrt{(-5)^2+(20-n)^2})^2[/tex]

Simplify:

[tex]169=(-5)^2+(20-n)^2[/tex]

Square (-5):

[tex]169=25+(20-n)^2[/tex]

Subtract 25 from both sides. The right cancels:

[tex](169)-25=(25+(20-n)^2)-25\\144=(20-n)^2[/tex]

Now, take the square root of both sides.

[tex]\pm\sqrt{144}=\sqrt{(20-n)^2}[/tex]

Simplify:

[tex]\pm12=(20-n)[/tex]

So, we have two solutions:

[tex](12=20-n)\text { or }(-12=20-n)[/tex]

On the left, subtract 20. On the right, also subtract 20:

[tex](-8=-n)\text { or }(-32=-n)[/tex]

Divide both sides by -1:

[tex](n=8)\text{ or } (n=32)[/tex]

So, our two possible answers are 8 or 32.

Answer:

y=8x

Step-by-step explanation:

There is no why intercept because there is no additional boarding fee, so the only part of the equation you get is y=mx.  In this equation, that is y=8x, where "x" is the number of hours in the cab, 8 represents the cost per hour, and "y" is the total cost of the entire cab ride.

Answer:

3

Step-by-step explanation:

To simplify this expression, we will simply work with the numerator, then the denominator, and then the fraction as a whole, following PEMDAS.

Numerator:  12 - 6 + 5 * (-3)^2

= 12 - 6 + 5 * (9)

= 12 - 6 + 45

= 6 + 45

= 51

Denominator:  17

So our simplified fraction is as follows:

51/17

Which can be reduced to the whole number, 3.

Answer:

26.8336 ≈ 26.83

Step-by-step explanation:

If x < 5, then we round down.

If x ≥ 5, then we round up.

2 decimal places is the hundredths place.

26.8336

3 < 5, so we round down

26.83

Answer:

2(1+4p-6p)-3(1-p)

Which could have been the expression Iris evaluated? Check all that apply.

A. 2^-6

B. 6^-4

C. 4^-3

D. (1/2)^-5

E. (1/4)^-3

A. 2^-6

= 1 / 2^6

= 1 / 2*2*2*2*2*2

= 1 / 64

B. 6^-4

= 1 / 6^4

= 1 / 6*6*6*6

= 1 / 1,296

C. 4^-3

= 1 / 4^3

= 1 / 4*4*4

= 1 / 64

D. (1/2)^-5

= 1 ÷ (1/2)^5

= 1 × 2/1^5

= 2^5

= 2*2*2*2*2

= 32

E. (1/4)^-3

= 1 ÷ (1/4)^3

= 1 × 4/1^3

= 4^3

= 4*4*4

= 64

Options A. 2^-6 and C. 4^-3 are equivalent to 1/64

Step-by-step explanation:

Answer:

1°

Step-by-step explanation:

There are 360 degrees in a circle.

Thus, if a circle turns x degrees, then it will represent x/360 of the entire circle.

Since the rotation represented 1/360 of the entire circle, this means that the measure of the angle must be only 1 degree.

Answer:180

Step-by-step explanation:

An angle turns through n one degree angles is said to have an angle measure of n degrees

Answer:

x = -19

Step-by-step explanation:

For this problem, we simply need to get rid of the fractions so we can easily solve for x.

To get rid of these fractions, we will multiply the whole equation by the LCD which is 2 * 3 = 6.

( x / 2) - ( 1 / 2) = ( 2x / 3) + ( 8 / 3 )

6 * ( x / 2) - 6 * ( 1 / 2) = 6 * (2x / 3) + 6 * ( 8 / 3 )

3x - 3 = 4x + 16

3x - 3x - 3 - 16 = 4x - 3x + 16 - 16

0x - 19 = x + 0

x = - 19

Thus, for the equation to be true, x must be equal to negative 19.

Cheers.

Answer:

Answer= -19

Step-by-step explanation:

x/2 - 1/2 = 2x/3 + 8/3

x-1 / 2 = 2x+8 / 3

(x - 1) × 3 = (2x + 8) × 2

3x - 3 = 4x + 16

3x - 4x = 16 + 3

-x = 19

x = -19.

Thus, the value of x will be -19.

Hope it helps.

Answer:

1. 9 feet

2. The ground

3. Absolute values of opposite numbers are the same

Step-by-step explanation:

Given

Distance up the apple tree = 9 feet up

Solving (a): How far he'll climb to come down

In this case, the distance from the ground up to the tree is the same distance back to the ground.

In other words;

Since he climbs 9 feet up, then he'll climb 9 feet down to the ground

Solving (b): What 0 represents

In this case, 0 represents the ground

Solving (c): Absolute values

The absolute values of opposite numbers (from negative to positive) are the same

Take for instance:

[tex]|-9| = 9[/tex]

[tex]|-3| = 3[/tex]
