Answer:

7.2

Step-by-step explanation:

The points shown form a right angle triangle along the x axis so the distance is the hypotenuse. So

a**2 + b**2 = c**2

4**2 + 6**2 = c**2

16 + 36 = c**2

52 = c**2

52**(1/2) = c

7.2 = c

Answer:

1 ton = 1000 kg

So, 17 ton = 17 × 1000

= 17000 kg

17000 + 200 kg = 17200 kg

[tex] \frac{17200}{8} = 2150kg[/tex]

Step-by-step explanation:

remember SOHCAHTOA

SOH is for sin

CAH is for cosin

TOA is for tan

line PS=14 so line QR=14

line PQ is your x value. so to solve, write out tan30=14/x

rewrite it so it now says x= 14/tan. type that in to your calculator and you get your answer

Answer:

x = 5, y = 15

Step-by-step explanation:

Use substitution to solve the system of equations.

We'll replace y in x + y = 20 with 3x, since y = 3x.

x + 3x = 20

Combine like terms

4x = 20

Divide by 4 on both sides

x = 5

Now to solve for y (don't forget!)

We'll plug x = 5 back into one of the original equations

y = 3(5) = 15

Check first equation:

15 = 3(5)

15 = 15

Check second equation:

5 + 15 = 20

20 = 20

Answer:

7 and 34

Step-by-step explanation:

let x and y be the 2 numbers with x > y

The 2 equations to solve are

x = 4y + 6 → (1)

x + y = 41 → (2)

Substitute x = 4y + 6 into (2)

4y + 6 + y = 41 , that is

5y + 6 = 41 ( subtract 6 from both sides )

5y = 35 ( divide both sides by 5 )

y = 7

Substitute y = 7 into (1)

x = 4(7) + 6 = 28 + 6 = 34

The 2 numbers are 7 and 34

Answer:

Solution given

5(1+s)=9s+6

distribute

5+5s=9s+6

subtract both side by 5s

5+5s-5s=9s-5s+6

solve like terms

5=4s+6

subtract both side by 6

5-6=4s+6-6

-1=4s

divide both side by 4

-1/4=s

Answer:

[tex]s=-\frac{1}{4}[/tex]

[tex]s=-0.25[/tex]

Step-by-step explanation:

[tex]5\left(1+s\right)=9s+6[/tex]

Apply distributive law:-

[tex]5\left(1+s\right)[/tex]

[tex]=5+5s[/tex]

[tex]5+5s=9s+6[/tex]

Now, Subtract 5 from both sides :-

[tex]5+5s-5=9s+6-5[/tex]

[tex]5s=9s+1[/tex]

Subtract 9s from both sides:-

[tex]5s-9s=9s+1-9s[/tex]

[tex]-4s=1[/tex]

Divide both sides by -4:-

[tex]\frac{-4s}{-4}=\frac{1}{-4}[/tex]

[tex]s=-\frac{1}{4}[/tex]

Answer: 2.3/225.4=0.01020408

Answer:

98.000

Step-by-step explanation:

Change the divisor 2.3 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.

We then have the equations:

2254 ÷ 23 = 98.000

and therefore:

225.4 ÷ 2.3 = 98.000

Both calculated to 3 decimal places.

Answer:

x = 10

6x - 6 = 54

Step-by-step explanation:

The hypotenuse of both triangles are 63 and 6x - 6; the second longest sides are 49 (greater than 35) and 42 (greater than 30).

So our proportion:

63/(6x-6) = 49/42

Cross multiply

63*42 = 49*(6x-6)

2646 = 294x-294

2940 = 294x

x = 10

Double-check:

63/(6*10 - 6) = 49/42

63/(60 - 6) = 49/42

63/54 = 49/42

7/6 = 7/6

6x - 6 = 6(10) - 6 = 60 - 6 = 54

Answer:

About 113.

Step-by-step explanation:

45 + 0.05t +0.58v = 55.29

v = 8

t is 113 text messages.

Kristy’s sent About 113 text messages..

An equation represents equality of two or more mathematical expression.

When someone asks you to solve an equation, then they usually mean to find the values of the unknowns for which that equation would be true (the equality between expressions should hold true for those values).

Solutions to an equation are those values of the variables involved in that equation for which the equation is true.

It is given that Kristy’s cellphone company charges a monthly rate of $45 plus $0.05 per text message sent and $0.58 per video messages sent.

Also Kristy’s sent 8 video messages in October and receive a bill for $55.29.

The equation form as;

45 + 0.05t +0.58v = 55.29

Solve for t when v = 8;

45 + 0.05t +0.58(8) = 55.29

t = 113

Therefore, she sent 113 text messages.
