Answer 1

The solution to the system of equations are (2, 5).

Solution:

The system of equations are

x + y = 7 – – – – (1)

2x – y = –1 – – – – (2)

To find x from equation (1):

x + y = 7

Subtract y from both sides of the equation, we get

⇒ x + y – y = 7 – y

x = 7 – y – – – (3)

Substitute (3) in (2) we get,

2(7 – y) – y = –1

14 – 2y – y = –1

14 – 3y = –1

Subtract 14 from both sides,

–3y = –15

Divide by –5 on both sides,

y = 5

Substitute y = 5 in equation (3)

x = 7 – 5

x = 2

The solution to the system of equations are (2, 5).

A fort had provisions for 175 men for 70 days. After 10 days, 25 men left the fort. How long will the provision last ?​

Answers

Answer:

70 days

Step-by-step explanation:

we  know that

A fort had provisions for 175 men for 70 days.

After 10 days a fort had provisions for 175 men for (70-10)=60 days

but

25 men left the fort

so

The remaining men are 175-25=150 men

Let

x ----> how long the provision will last

we know that

The equation that represent this problem is an inverse variation

[tex]175(60)=150(x)[/tex]

as the number of men decreases the number of days increases

solve for x

[tex]x=175(60)/150=70\ days[/tex]

using proportion

[tex]\frac{175}{60}=\frac{150}{x}\\\\x=150(60)/175\\\\x=70\ days[/tex]

Solve this equation for x in terms of y and z
7x - 5y - 2z = 4
What is he value of x when y = 5 and z = 3

Answers

Answer:

x = 5

Step-by-step explanation:

Step 1:  Set y to 5 and z to 3

7x - 5(5) - 2(3) = 4

7x - 25 - 6 = 4

7x - 31 = 4

Step 2:  Add 31 to both sides

7x - 31 + 31 = 4 + 31

7x = 35

Step 3:  Divide both sides by 7

7x / 7 = 35 / 7

x = 5

Adds 43 both sides

[tex]11+43\leq y[/tex]

[tex]54\leq y[/tex]

1. Moesha needs $79 for a class trip. 59
She already has $22 and she can earn
the rest by babysitting for 8 hours.
If h represents her hourly earnings,
which of the following equations can
be solved to find Moesha's hourly
earnings? Select all that apply.​

Answers

Answer: 79=8h +22

Step-by-step explanation: 79 total needed 8h equals 8 times her hourly earning plus 22 what she already haves should equal 79.

Final answer:

To find Moesha's hourly earnings for babysitting, we subtract the amount she already has ($22) from the total needed ($79) to calculate the amount she needs to earn ($57), and divide this by the number of hours she will babysit (8). This gives us the equation 8h = $57, which we solve by dividing both sides by 8, leading us to find that Moesha earns $7.125 per hour.

Explanation:

Moesha needs $79 for a class trip and already has $22. She will earn the remaining amount by babysitting for 8 hours. If we use h to represent Moesha's hourly earnings, we need to set up an equation that when solved, will find her hourly earnings. The total amount Moesha needs to earn from babysitting is $79 - $22, which equals $57. Since she is babysitting for 8 hours, we divide the total amount she needs to earn by the number of hours she will work: $57 ÷ 8 hours.

Putting this into an equation, we come up with 8h = $57. To find her hourly earnings, h, we divide both sides of the equation by 8, giving us h = $7.125 per hour. Therefore, Moesha will earn $7.125 for each hour of babysitting she does.

How do I solve for what is sin A for the triangle shown

Answers

Option a:

sin A for the triangle is [tex]\frac{3}{5}[/tex].

Solution:

The given triangle is a right triangle.

The adjacent side to angle A is AC.

The opposite side to angle A is BC.

Hypotenuse is AB.

AC = 8, BC = 6 and AB = 10.

Using trigonometric ratio formulas,

[tex]$\sin \theta=\frac{\text { Opposite side }}{\text { Hypotenuse }}[/tex]

[tex]$\sin A=\frac{BC}{AB}[/tex]

[tex]$\sin A=\frac{6}{10}[/tex]

Divide both numerator and denominator by 2, we get

[tex]$\sin A=\frac{6\div2}{10\div 2}[/tex]

[tex]$\sin A=\frac{3}{5}[/tex]

Hence sin A for the triangle is [tex]\frac{3}{5}[/tex].

Option a is the correct answer.

Answers

The measure of ∠1 is 95°

Solution:

Given a || b.

m∠6 = 85° and m∠3 = 2x°

∠6 and ∠3 are co-interior angles.

Co-interior angles add up to 180°.

⇒ m∠6 + m∠3 = 180°

⇒ 85° + 2x° = 180°

Subtract 85° from both sides.

⇒ 2x° = 95°

m∠3 = 95°

If two lines cut each other, then vertically opposite angles are congruent.

⇒ m∠1 = m∠3

m∠1 = 95°

Hence the measure of ∠1 is 95°.

Paul, Fiona and Pip share some sweets in the ratio 4:1:1. Paul gets 48 sweets. How many did Pip get?

Answers

Answer:

12

Step-by-step explanation:

4:1:1, from the ratio, you know that there are 6 in total (4+1+1)

so set up a proportion

(4/6) = (48/x)

so... (6 x 48) / 4 = x

x = 72, the total

now repeat to find the value for Pip

(1/6) = (x/72)

72 / 6 = 12

Final answer:

Paul, Fiona, and Pip share sweets in a 4:1:1 ratio. Paul's 4 parts amount to 48 sweets, so each part is 12 sweets. Consequently, Pip receives 12 sweets.

Explanation:

The student's question is asking how many sweets Pip would get if Paul, Fiona, and Pip share some sweets in the ratio 4:1:1 and Paul gets 48 sweets. To solve this, we'll need to break down the problem and figure out how many parts the total number of sweets is being divided into. Then, we'll calculate the number of sweets per part using the information given.

Since the ratio is 4:1:1, there are a total of 4 + 1 + 1 = 6 parts. Paul's share is 4 parts, and since Paul gets 48 sweets, each part is worth 48 sweets ÷ 4 parts = 12 sweets.

Both Fiona and Pip get 1 part each. So, since each part equals 12 sweets, Pip gets 12 sweets.
