Answer:

I think 10

Step-by-step explanation:

you ad up the books so you would have 10+15+8+7=40. Then you divide by 4 to get the average. So it equals 10.

Answer:

She needs 7 more boxes.

Step-by-step explanation:

100-16=84

84/12=7

Answer:

y = –7x – 11

6x – 4y = 10

Step-by-step explanation:

From the question given above, we obtained:

x = –1

y = –4

y = ?x – 11 ....... (1)

6x – ?y = 10b......... (2)

Let the two unknown be a and b. Thus the above equation becomes:

y = ax – 11 ......... (3)

6x – by = 10 .......(4)

Next, we shall determine the value of 'a' and 'b'. This can be obtained as follow:

For a:

y = ax – 11

x = –1

y = –4

–4 = a(–1) – 11

–4 = –a – 11

Collect like terms

–4 + 11 = –a

7 = –a

Multiply through by –1

a = –7

For b:

6x – by = 10

x = –1

y = –4

6(–1) – b(–4) = 10

–6 + 4b = 10

Collect like terms

4b = 10 + 6

4b = 16

Divide both side by 4

b = 16 / 4

b = 4

Finally, we shall substitute the value of a and be into equation 3 and 4 respectively.

y = ax – 11

a = –7

y = –7x – 11

6x – by = 10

b = 4

6x – 4y = 10

Therefore, the complete equation are:

y = –7x – 11

6x – 4y = 10

Answer: Jakob will run 3 1/2 miles in 30 min

Step-by-step explanation: you need to take 7 in half  because half of an hpur is 30 minutes so half of seven is 3 1/2 so that is the answer

Answer:

3.5 miles

Step-by-step explanation:

1 hour = 60 minutes

Proportions:

7 miles = 60 minutes

J miles = 30 minutes

J = 7*30/60

J = 3.5 miles

θ = 41.81°

Step-by-step explanation:

Given

[tex]\frac{2}{3}[/tex] = sinθ , then

θ = [tex]sin^{-1}[/tex] ( [tex]\frac{2}{3}[/tex] ) ≈ 41.81°

Answer:

27

Step-by-step explanation:

Answer:

27.

Step-by-step explanation:

(-43)+37+33

= 27.

Answer:

98= 4p + 38

4p = 38 - 98

4p = - 60

P = - 60/4

P = -15

Answer:

p=15

Step-by-step explanation:

98=4p+38

(98-38)=4p

60=4p

(60/4)=(4p/4)

15=p

Answer:

254.34 inches²

Step-by-step explanation:

The formula for area of a circle is: pi x r². The radius is half of the diameter (18) which in this case would be 9. Square it to get: 81. Multiply by pi: 81 x 3.14 = 254.34.

Answer:

$4 (nearest dollar) ;

$4.4 (nearest dime) ;

$4.41 (nearest penny

Step-by-step explanation:

The actual price of premium gasoline is $4.409 per gallon.

A penny = $0.01 or 1 cent

A dime = $0.1 or 10 cent

Price of premium gasoline to the nearest dollar :

$4.409 is rounded to the nearest unit = $4

Price of premium gasoline to the nearest penny : = $4.409 is rounded to the nearest hundredth = $4.41

Price of premium gasoline to the nearest dime : = $4.409 is rounded to the nearest tenth = $4.4

Step-by-step explanation:

Answer:

[tex] \purple {\bold {m\angle A =70\degree}} [/tex]

Step-by-step explanation:

ABCD is a trapezoid. AB || DC and AD is transversal...(given)

[tex] AD \cong BC.. (given) [/tex]

Therefore, ABCD is an isosceles trapezoid.

Measures of base angles of isosceles trapezoid are equal.

[tex] \therefore m\angle D =m\angle C[/tex]

[tex] \because m\angle C =110\degree... (given) [/tex]

[tex] \therefore m\angle D =110\degree [/tex]

[tex] m\angle A+ m\angle D =180\degree [/tex]

(interior angles on the same side of transversal)

[tex] m\angle A+ 110\degree =180\degree [/tex]

[tex] m\angle A =180\degree -110\degree [/tex]

[tex] \purple {\bold {m\angle A =70\degree}} [/tex]

Step-by-step explanation:

Answer:

262,000

Step-by-step explanation:

Step-by-step explanation:

f(x) = 4x-5

g(x) = 2x

(f + g)(x)=f(x) +g(x)=4x-5+2x=6x-5

Answer:

EF = 8

Step-by-step explanation:

The midsegment EF is half the sum of the parallel bases , that is

x = [tex]\frac{x-5+2x-3}{2}[/tex] ( multiply both sides by 2 to clear the fraction )

2x = 3x - 8 ( subtract 2x from both sides )

0 = x - 8 ( add 8 to both sides )

8 = x

Thus

EF = x = 8

AD = x - 5 = 8 - 5 = 3

BC = 2x - 3 = 2(8) - 3 = 16 - 3 = 13

Answer:

The answer is 380

Step-by-step explanation:

[tex]g(100) = 4(100 - 5) \\ = 4 \times 95 \\ = 380[/tex]

Answer:

g(100) = 380

Step-by-step explanation:

Replace x with the given number; which in this is case is 100

g(100) = 4(100-5)

g(100) = 4(95)

g(100) = 380
