One number is three less than two times another number. If the sum of the numbers is 15, find the numbers

Answer:

D. -7

Step-by-step explanation:

Since positive 7 represents a gain of seven yards, a loss would be represented by a negative number.

So, a loss of seven yards will be represented by -7.

So, the correct answer is D. -7

Answer:

i cant help that much but u can try using photomath

Answer:

126

Step-by-step explanation:

What is the volume of a figure with that is 2 inches wide, 7 inches tall and 9 inchesn = Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.    

2x7x9 = 126

Answer:

126 inches³

Step-by-step explanation:

The volume of a figure is l×w×h.

So,

9 × 2 × 7 = 126

Answer:

(5,-3)

Step-by-step explanation:

Given that,

The coordinates of Q = (3,1)

The midpoint of QR = (4,-1)

We need to find the coordinates of point R.

We know that, according to mid-point theorem,

[tex](x_m,y_m)=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]

Let (x₂,y₂) be the coordinates of point R.

So,

[tex](4,-1)=(\dfrac{3+x_2}{2},\dfrac{1+y_2}{2})\\\\\dfrac{3+x_2}{2}=4\ and\ \dfrac{1+y_2}{2}=-1\\\\3+x_2=8\ and\ y_2+1=-2\\\\x_2=5\ and\ y_2=-3[/tex]

So, the coordinates of point R is (5,-3).

Answer:

I think 44 degrees

Step-by-step explanation:

73-29=44

Answer:

44

Step-by-step explanation:

The value of u, combined with the angle directly next to it (with the measurement of 29°), is a vertical angle to the opposite given angle (73°).

Note that, by the definition of vertical angles, angles directly next and opposite of each other have the same measurement. Set the equation:

u + 29 = 73

Isolate the variable, u. Note the equal sign, what you do to one side, you do to the other. Subtract 29 from both sides:

u + 29 (-29) = 73 (-29)

u = 73 - 29

u = 44

44° is your answer for u.

8-3=8-3

Step-by-step explanation:

Answer:

B. M - J = 6

Step-by-step explanation:

Mike won 6 more games than Jeanie

so J + 6 = M

Subtract J from both sides of the equation

J - J + 6 = M - J

Simplify

6 = M - J

or

M - J = 6

Answer:

Both are wrong.

Step-by-step explanation:

We have that:

Both decomposed the fraction [tex]\frac{13}{8}[/tex] into a sum of fractions. Whoever's decomposition sum has a value of [tex]\frac{13}{8}[/tex] is correct.

David:

[tex]1 + \frac{1}{8} + \frac{3}{8} = \frac{8}{8} + \frac{1}{8} + \frac{3}{8} = \frac{8+1+3}{8} = \frac{12}{8}[/tex]

[tex]\frac{12}{8} \neq \frac{13}{8}[/tex], which means that David is wrong.

Patti

[tex]\frac{4}{8} + \frac{2}{8} + \frac{5}{8} = \frac{4+2+5}{8} = \frac{11}{8}[/tex]

[tex]\frac{11}{8} \neq \frac{13}{8}[/tex], which means that Patti is wrong.

So the answer is that both are wrong.

9+8=17+9+9=18=35+9=44

Answer:

the answer is 29.7

Step-by-step explanation:

inverse tangent of (4/7)

Answer:

integers

Step-by-step explanation:

Integers include positive and negative including 0, but not including fractions or decimals

Answer:

Integers because:

Whole doesn't include negatives.

Irrational includes both, but not this one.

Natural numbers are only possitive values.

Answer:

x = 1/2 , x = -1/2

Step-by-step explanation:

Given equation;

169x² - 42.25

Find:

Solution of equation using square root

Computation:

169x² - 42.25

We know that 13² = 169 and 6.5² = 42.25

So,

[13x]² - [6.5]²

a² - b² = (a + b)(a - b)

So,

[13x]² - [6.5]² = [13x + 6.5][13x - 6.5]

So,

13x + 6.5 = 0 , 13x - 6.5 = 0

x = 6.5 / 13 , x = -6.5 / 13

x = 1/2 , x = -1/2

Answer:

A.) 0.2

B.) 3.2

C.) 0.4

D.) 0.5

Step-by-step explanation:

Arrival rate, λ = 8 per hour

Service rate, μ = 10 boats per hour

1.)

Probability that boat dock will be idle, P0:

P0 = 1 - λ/μ

P0 = 1 - 8/10

P0 = 1 - 0.8

P0 = 0.2

Average number of boats waiting for service :

Lq = λ² ÷ μ(μ - λ)

Lq = 8² ÷ 10(10- 8)

Lq = 64 ÷ 10(2)

Lq = 64 ÷ 20

Lq = 3.2

Average time spent waiting for service, Wq :

Wq = λ ÷ μ(μ - λ)

Wq = 8 ÷ 10(10- 8)

Wq = 8 ÷ 10(2)

Wq = 8 / 20

Wq = 0.4 hour

Wq = 0.4 * 60 = 24 minutes

Average time spent at the dock :

1 ÷ (μ - λ)

1 ÷ (10 - 8)

1 ÷ 2

= 0.5 hour

= 0.5 * 60 = 30 minutes

Answer:

no

Step-by-step explanation:

(6,0) would be 0 = 8(6), so no

Answer:

the answer is 8

Step-by-step explanation:

the expression is written as (n/2 - 6)+ 10

therefore when n=8..

(8/2 - 6) + 10

we now have, (4-6)+10

(-2)+10=8...

Answer: 1075 sq. ft

Step-by-step explanation:

A = length times width

First split the shape into two rectangles

Area of rec 1 = 25 times 8 = 200

Area of rec 2 = 35 times 25 = 875

200+875 = 1075 sq. ft
