Please help guys lol I have no clue how to do this... it’s the square root method?

Answer:

Step-by-step explanation:

Let's solve for x.

−3x+8y=73

Step 1: Add -8y to both sides.

−3x+8y+−8y=73+−8y

−3x=−8y+73

Step 2: Divide both sides by -3.

−3x

−3

=

−8y+73

Answer:

x−7y=−46

Step 1: Add 7y to both sides.

x−7y+7y=−46+7y

x=7y−46

Answer:

x=7y−46

Answer: a=4b/5

Step-by-step explanation:

To solve for a, we want to use algebraic properties to isolate a.

3a+2b=6b-2a               [add both sides by 2a]

5a+2b=6b                     [subtract both sides by 2b]

5a=4b                           [divide both sides by 5]

a=4b/5

Now, we have found that a=4b/5.

-5

A function is where each input is related to exactly one output. Because -5 was already previously listed as an x value in an ordered pair, it can not be used in a function. Another way of thinking of a function is if it passes the vertical line test where a vertical line can only pass through your line once. Let me know if this doesn't make sense!

Answer:

x = (√6/√5) - 1

Step-by-step explanation:

- 10 x = 5x^2 -1

can be written as

5x² + 10x - 1 = 0

completing the square method :

for quadratic equation of the format ax² + bx + c = 0 ,

step 1, divide equation by a

therefore. dividing the equation by 5

=> x² + 2x - (1/5) = 0

=> x² + 2x = 1/5

c - 2b/4 = -1/5 - (2(2)/4) = -(6/5)

b/2 = 1

=> x² + 2x +1 = 6/5

=> (x + 1)² = 6/5

=> x = (√6/√5) - 1

Answer:

[tex] m\angle L = 111\degree \\

Step-by-step explanation:

Since, angle L and angle M are supplementary.

[tex]\therefore m\angle L + m\angle M= 180\degree \\ \therefore \: 12x + 45 + 18x - 30 = 180 \degree \\ \therefore \: 30x + 15= 180 \degree\\ \therefore \: 30x= 180 \degree - 15 \degree\\ \therefore \: 30x= 165 \degree \\ x = \frac{165 \degree}{30} \\ x = 5.5 \degree \\ \\ m\angle L = 12x + 45 \\ m\angle L = 12 \times 5.5 + 45 \\ m\angle L = 66 + 45 \\ \huge \red{ \boxed{ m\angle L = 111 \degree}} \\ \\ m\angle M=18x - 30 \\ m\angle M=18 \times 5.5 - 30 \\ m\angle M=99 - 30 \\ \huge \purple{ \boxed{ m\angle M=69 \degree}} \\ [/tex]

Answer:

79

Step-by-step explanation:

the total of 90, 83, 78, 95= 346 which averages to 86.5

346+79=425

425/5= 85

If Laura ascends 8 feet, her new position relative to the surface is 24 feet below the surface.

If the direction is same (like coefficients), we add them and if the direction is opposite (unlike coefficients) then we subtract them. The sign can be taken as per our convenience for a particular direction.

Similarly, as given, if Laura is 32 feet below the surface in a cave (say negative direction)

- 32 feet

and then further she ascends 8 feet that is upward direction (say positive direction),

+ 8 feet

then for calculating final distance of Laura position from surface, we get the expression as:

-32 + 8 = - 24

Hence the final result value is negative 24, it means Laura is bellow the surface, by the distance of 24 feet.

Answer:

  40 ft

Step-by-step explanation:

The tree's shadow is 60/12 = 5 times the length of the shadow of the post. So, we figure the tree is 5 times the height of the post:

  5(8 ft) = 40 ft . . . height of tree

__

You may want to write a proportion:

  tree height/tree shadow = post height/post shadow

  t / 60 = 8 / 12

  t = 60(8/12) = 40 . . . . multiply by 60

Answer:

D.

Step-by-step explanation:

Answer:

CD=EF. -(1)

EF=GH. -(2)

Adding (1) and (2)

[LHS(1)+LHS(2) = RHS(1)+RHS(2)]

CD+EF = EF+GH

EF on both sides cancel each other.

CD= GH

Option D is the answer.

Step-by-step explanation:

Answer:

3526.49

Step-by-step explanation:

You look at two 2dp after the decimal point. It is 8. You look to the number on the right which is 5 so you round up to 9.

Answer:

the best eatimated answer would be 150 miles.

24% of 603 = 144.72

so you can round it to 150

Answer:

24% of 603 is 144.72, so the best estimate would probably be 150 miles.

To find the relative frequency of something, take the frequency and divide by the total number of data values.

Total number of data values = 1170

Row one: relative frequency = 5 / 1170 = 0.0043

Row two: relative frequency = 17 / 1170 = 0.0145

Row three: relative frequency = 52 / 1170 = 0.0444

Row four: relative frequency = 118 / 1170 = 0.1009

Row five: relative frequency = 172 / 1170 = 0.1470

Row six: relative frequency = 232 / 1170 = 0.1983

Row seven: relative frequency = 219 / 1170 = 0.1872

Row eight: relative frequency = 172 / 1170 = 0.1470

Row nine: relative frequency = 95 / 1170 = 0.0812

Row ten: relative frequency = 57 / 1170 = 0.0487

Row eleven: relative frequency = 23 / 1170 = 0.0197

Row twelve: relative frequency = 8 / 1170 = 0.0068
