The correct answer would be (4*5)w because you would multiple the number of pages that she reads per week then you multiply that by how many weeks she reads.

Solution:

The given situation about Bridget is :

Bridget reads 5 pages of her book per day 4 days per week.

Describing the situation in unitary method:

Number of pages read by Bridget in a week(4 Days) = 5 × 4 = 20 pages

In w Weeks , number of days = 7 w

She reads 5 pages for 4 days in a week.

In w Weeks , number of days Bridget read = 7 w -3 w= 4 w days, where w=1,2,3,4,5......

Number of  pages read by Bridget in w week= Number of pages read in a week × Number of days in w week in which Bridget read 5 pages

             =  5 ×(4 w)

              = 20 w   which is equivalent to

=  5 × (w+w+w+w)→→→Option (D)

What value or values of x satisfy 2x + 5.31 = 4.2?
Softa [21]

Answer:  x can equal -3.2 or -7.4.

Step-by-step explanation:

The correct expression is:

2|x+5.3|=4.2

So, we have an absolute value equation, where it can be positive or negative:

  • Positive

2 (x+5.3)=4.2

2x+10.6 =4.2

2x=4.2-10.6

2x = -6.4

x= -6.4/2

x = -3.2

  • Negative

2[-(x+5.3)]=4.2

-2x-10.6 =4.2

-2x= 4.2+10.6

-2x= 14.8

x= 14.8/-2

x= -7.4

x can equal -3.2 or -7.4.

Consider a Triangle ABC like the one below. Suppose that C = 98, A = 74, and b = 11 (figure is not drawn to scale.) solve the tr
Degger [83]

Answer:

A=73.8\°

B=8.2\°

c=76.3\ units

Step-by-step explanation:

step 1

Find the measure of side c

Applying the law of cosines

c^{2}= a^{2}+b^{2}-2(a)(b)cos(C)

substitute the given values

c^{2}= 74^{2}+11^{2}-2(74)(11)cos(98\°)

c^{2}=5,823.5738

c=76.3\ units

step 2

Find the measure of angle A

Applying the law of sine

\frac{a}{sin(A)}=\frac{c}{sin(C)}

substitute the given values

\frac{74}{sin(A)}=\frac{76.3}{sin(98\°)}

sin(A)=(74)sin(98\°)/76.3

A=arcsin((74)sin(98\°)/76.3)

A=73.8\°

step 3

Find the measure of angle B

we know that

The sum of the internal angles of a triangle must be equal to 180 degrees

so

A+B+C=180\°

substitute the given values

73.8\°+B+98\°=180\°

171.8\°+B=180\°

B=180\°-171.8\°=8.2\°

I need help with this problem.<br>please help<br><br>Directions: Solve each system by substitution.​
artcher [175]

Answer:

(-1,-6)

Step-by-step explanation:

Plug 6x for y into the bottom equation:

2x+3(6x)= -20

2x+18x= -20

20= -20

x= -1

Substitute -1 for x in the equation for y:

y=6(-1)

y=-6

I hope I could help :)
