Answer:

Ryanne is 14

Let’s make her brother “x”

Her brother is three more then half her age.

So

X= 14/2 + 3

So solve.

14/2=7

7+3=10

X=10

Her brother is 10 or (c)

Answer:

He's 10

Step-by-step explanation:

14 ÷ 2= 7

7+3= 10

Hope this helps! :)

Step-by-step explanation:

1) let n be number of cans

if 1 can has 3 tennis balls, then

n cans will have 3n (n*3) tennis balls.

thus, 3n= 27 (equation)

n=27/3

n=9

2) let the initial temp. be y

y - 5° F = 37 ° F

3) average speed= total distance/ total time

= 40 m / 20 s

= 2 m/s

let me know if there's something you didn't understand, thank you!

Answer:

The answer is C. The translation of a line is a pair of parallel lines.

Step-by-step explanation:

A, B, and D are true. C is not true, and therefore the correct answer.

Step-by-step explanation:

P = 4x + 24

Step-by-step explanation:

Sides of the triangle:

bottom = x

side1 = 2x + 13

side2 = x + 11

Perimeter is the sum of side lengths:

P = x + 2x + 13 + x + 11 = 4x + 24

Step-by-step explanation:

the answer is

B) 18

judging by tha fact that its 10 dollars per month

Answer:

Assuming that each equation only has one property. 1. Would be any line with a negative number as the slope Example: y = -2x, and no slope intercept would be attached because it is asking for a zero. Now if they are asking for an actual 0 attached (this doesn't need to be added unless asked) just add + 0 to the end which would be y = -2x +0. 2. Would be a line without a slope but rather an intercept. Example: y = 3. Now 3. Would be any equations with the x equivalent to a number.  Example: x = 2

Therefore, the answers would be: 1. y = -2x + 0 (or any other negative number as the slope). 2. y=3 or any other integer. 3. x=2 or any other integer.

Step-by-step explanation:

Answer:

the third one is the correct one

Step-by-step explanation:

because there are 5 numbers between 90 and 99 and 6 number between 80 and 89 and the third diagram is the only one that matches

The height of the tallest doll = 12 inches

The height of 2nd doll = 12×7/10

The height of 3rd doll = 12×7/10×7/10 = 12×(7/10)²

The height of 4th doll = 12×7/10×7/10×7/10 = 12×(7/10)³

Therefore the height of the smallest doll = 12×[tex]7/10^{(n-1)}[/tex]

where n is the number of dolls

So, if there are 5 dolls then the height of the smallest doll will be

12×[tex]7/10^{(5-1)}[/tex] = 12×[tex]7/10^{4}[/tex] = 2.8812 inches

Answer:

first question z = 9

second question is not

third question h = 3 3/4

Step-by-step explanation:

Answer:

1) p≥2

2) e-9=13

3) f<5

Step-by-step explanation:

1) If there are at least two slices left, there could be more, so use p≥2, meaning p is greater than or equal to 2.

2) e is your starting amount, so put that first, then it says it decreases by 9, so it is e-9=13.

3) If there are fewer than 5, it can not be 5 so you use <.

f<5 or gallons is less than 5.

Number 1,

Since we know the outcome to the equation has to [tex]3\frac{10}{43}[/tex], we can solve each problem regularly to get the answer

_________________

[tex]\huge\blue{\mid{\fbox{\tt{NUMBER\:ONE}}\mid}}[/tex]

[tex]6\frac{5}{7}-6\frac{2}{6}\\\\3\frac{8}{21}[/tex]

_________________

[tex]\huge\blue{\mid{\fbox{\tt{NUMBER\:TWO}}\mid}}[/tex]

We simply can eliminate this option due to it being addition, when one of the numbers is already bigger than what we want,

_________________

[tex]\huge\blue{\mid{\fbox{\tt{NUMBER\:THREE}}\mid}}[/tex]

[tex]8\ \frac{8}{14}-5\ \frac{1}{3}\\\\3 \frac{5}{21}[/tex]

This equation also equals to [tex]3 \frac{10}{42}[/tex], so we found our answer!

Answer:

C

D

Step-by-step explanation:

part A

an area is always the multiplication of 2 dimensions (which leads to a square for totally regular shapes like a square or a circle).

in case of a rectangle it is length × width.

and that means in our case here

1 mile × 1/6 mile = 1/6 mile²

after all, 1×1/6 = 1/6.

I know this might look disappointing, but do not forget : a mile² is something else than a mile.

part B

3/4 (or any fraction) of something means to "apply" a factor of 3/4 (that fraction) to that something.

3/4 of 12 apples = 3/4 × 12 = 3×12/4 = 36/4 = 9

and indeed, 9 apples represent 3/4 of 12 apples.

so, yes, it means we need to multiply by the top part of the fraction (numerator) and divide by the bottom part (denominator).

therefore, D is the right answer.

for our example here, 3/4 of 1/6 mile² is

3/4 × 1/6 = 3/24 = 1/8 mile²

I think it's 103

Answer:

3/10 or 0.3

Step-by-step explanation:

The probability of spinning a prime number:

There are 3 prime numbers (2, 3, 5) and 5 possible outcomes

3/5 is the probability of spinning a prime number

The probability of not flipping head (flipping tails)

1/2

Multiply the probabilities together

3/5 x 1/2

3/10

Complete expressions using the distributive property are:

This property states that multiplying the total of two or more addends by a number will produce the same outcome as multiplying each addend by the number separately and then adding the results together.

Given three incomplete equations

25y + 30 = 5( __y + __ )

−12y + 15 = −3( __y + (__) )

36y − 9 = 3( __y − __ )

from equation 1

25y + 30

taking 5 common

=>5(5y + 6)

from equation 1

−12y + 15

taking -3 common

=>−3( 4y + (-5) )

from equation 1

36y − 9

taking 3 common

=>3( 12y − 3)

therefore, The Solved equation is a way of simplification using the distributive property.

Answer:

30 degrees

Step-by-step explanation:

I'm guessing this is a isosceles triangle which means that the the 2 base angles are 75 degrees meaning that if u add them up together that is 150 degrees and to find the angle BAC you have to do 180-150 which means it is 30 degrees

Answer:

Length of CD: 10.2956

Step-by-step explanation:

The length of the horizontal is 9. The length of the vertical is 5. Plug these two into the pythagorean theorem: [tex]9^2+5^2=(CD)^2[/tex] which simplifies to: [tex]106 = (CD)^2[/tex]. That simplifies to 10.2956

Answer:

C. The attached

Step-by-step explanation:

Our total is 44 dollars. This means that the largest bar, our whole, should be 44.

-> This rules out option D

Now, 4 sweatshirts are being bought. This means the 44 dollars should be broken up into 4 different parts since they all "cost the same amount of money."

-> This rules out options A, C, and D.

This leaves us with the correct option of option C.

Answer:

x = -2

Step-by-step explanation:

hdiwnohdiwmnwidn

3(x - 1) - 5x = 1 - 7(2 + x)

3x - 3 - 5x = 1 - 14 + 7x

3x - 5x = -2x

-2x - 3 = 1 - 14 + 7x

1 - 14 = -13

-2x - 3 = -13 + 7x

      +3 |  +3 + 7x

    -2x  | -10 + 7x

      2   |           2

        x = -10 + 4.5x

4.5 rounded is 5.

x = -10 + 5x

-10/5 = -2
