Answer 1

Cost of a television Ms. Singh wants to buy = £840

Ms. Singh's weekly wage = £300

Money she saves each week :

= 40% of her weekly wage

[tex] =\tt 40\% \: of \: 300[/tex]

[tex] = \tt \frac{40}{100} \times 300 [/tex]

[tex] =\tt \frac{40 \times 300}{100} [/tex]

[tex] =\tt \frac{12000}{100} [/tex]

[tex]\color{plum} = \tt£120[/tex]

Thus, Ms. Singh's weekly savings = £120

Number of weeks in which she will be able to buy a TV :

[tex] = \tt \frac{840}{120} [/tex]

[tex]\color{plum} =\tt 7 \: weeks[/tex]

Therefore, Ms. Singh will be able to buy a TV from her savings in 7 weeks.

John is 5 years older than Mary. In 10 years, twice John's age decreased by Mary's age is 35, and John's age will be
twice Mary's current age. Find their ages now.
If x is Mary's age now and yis John's age now, which system of equations could not be used to solve the problem?

Answers

Answer:

M=15

J=20

Step-by-step explanation:

Let J and M be the present age of John and Mary respectively:

J=M+5

2(J+10)−(M+10)=35

2(M+5+10)−(M+10)=35

2M+30−M−10=35

M=15

J=20

Mahra has 3 adults and 2 children coming over. She is going to serve 2 small apple pies. If she plans to give each person, including herself, an equal amount of pie. How much pie will each person get?

Answers

Answer:

She has 5 visitors + herself=6

Six people share 2 pies

She'll have to cut each pie into 3 equal pieces

So everyone will get a third of an apple

That is 1/3

Solving systems of equations using substitution. y=2x+8. y=5-x

Answers

Answer:

(x, y) = (-1, 6)

Step-by-step explanation:

y = 2x + 8

y = 5 - x

Substituting the second equation into the first equation, we get:

5 - x = 2x + 8

5 = 3x + 8

-3 = 3x

x = -1.

So, y = 5 - (-1).

Simplifying, we get:

y = 6.

Answers

Given :

On a farm, 4 and half out of every 15 acres of the land are used to grow crops.

Wheat is grown on 5/8 of the land used to grow crops.

To Find :

The total area of the land on the farm is used to grow wheat.

Solution :

Land required to grow crops on every 15 acres is :

C = 4.5 or C = [tex]\dfrac{9}{2}[/tex] acres.

Now, it is given that wheat is grown on [tex]\dfrac{5}{8}[/tex] of the land used to grow crops.

[tex]W = \dfrac{9}{2}\times \dfrac{5}{8}\\\\W = \dfrac{45}{16}\ acres[/tex]

Now,  percentage of the total area of the land on the farm is used to grow wheat is :

[tex]\% W = \dfrac{45}{16\times 15 }\times 100\\\\\%W = 18.75 \%[/tex]

Hence, this is the required solution.

Answer:

8(3y + 2) = 8 * 3y + 8 * 2 = 24y + 16

Step-by-step explanation:

The outer rectangle has width 8 and length 3y + 2.

The area of the outer rectangle is length times width or width times length, so the area is 8(3y + 2).

We can also find the area by finding the area of each small rectangle, and adding the areas together.

The left small rectangle has dimensions 8 and 3y.

A1 = WL = 8 * 3y = 24y

The right small rectangle has dimensions 8 and 2.

A2 = WL = 8 * 2 = 16

The total area of both small rectangles is 24y + 16

That tells use that

8(3y + 2) = 8 * 3y + 8 * 2 = 24y + 16

This is the distributive property at work.

Area of rectangle: length x width

Length: (3y + 2)
Width: 8

Area:
= (3y+2) x 8
= 8(3y) + 8(2)
= 24y + 16

The answer is 24y + 16.

If 1/4 gallons of water are enough to fill 7/10 of the pool how much water is nessacary to fill in the entire pool

Answers

Answer:  5/14 gallons

============================================================

Work Shown:

1/4 = 0.25

7/10 = 0.70 = 70%

We are told that 0.25 gallons of water fills 70% of the pool

We want to find how many gallons of water (call it x) are needed to fill 100% of the pool.

Set up the proportion below and solve for x

(0.25 gallons)/(70% filled) = (x gallons)/(100% filled)

0.25/70 = x/100

0.25*100 = 70x ....... cross multiply

25 = 70x

70x = 25

x = 25/70

x = (5*5)/(5*14)

x = 5/14 gallons

----------------------------------------

An alternate method:

1/4 gallons = 7/10 pools filled

(10/7)*(1/4 gallons) = (10/7)*(7/10 pools filled)

(10*1)/(7*4) gallons = (10*7)/(7*10) pools filled

10/28 gallons = 1 pool filled

(5*2)/(14*2) gallons = 1 pool filled

5/14 gallons = 1 pool filled

In the second step, I multiplied both sides by 10/7 so that the "7/10" turns into "1".

----------------------------------------

Yet another alternate method:

1/4 = 10/40

7/10 = 28/40

We need 10/40 gallons of water to fill 28/40 of one pool. We can multiply both fractions by 40 to indicate that 10 gallons of water will fill up 28 pools.

So we have this ratio

10 gallons : 28 pools

Dividing both parts by 28 tells us how many gallons are needed for one pool

10 gallons : 28 pools

10/28 gallons : 28/28 pools

10/28 gallons : 1 pool

5/14 gallons : 1 pool
