Answer: 40

Step-by-step explanation:

66-26=40

Answer:

40 trees

Step-by-step explanation:

You started with 26 trees. At the end, you will have 66. It's not 26+66 it is 66-26=trees. Trees=40. So, the workers planted 40 trees.

Answer:

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

m\angle M = 69\degree [/tex]

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:

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:

  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: 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.

Answer: 12

Step-by-step explanation: 6 times 2 is 12 and she has a 6 inch string and each peace is 1/2 inch long so she would have 12 peaces of string.

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.

The mistake that Carina made is she should have subtracted 3.40 from 5.27.

 The equation that represents the total amount spent is: $5.27 = $3.40 + $0.85x

Answer:

d. -24

Step-by-step explanation:

M(-1)=(-1)^2-3(-1)

M(-1)=1+3

M(-1)=4

N(-1)=-1-5

N(-1)=-6

MN(-1)=(4)(-6)

MN(-1)=-24

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:

#6 is 17 days

Step-by-step explanation:

This is how I answered it

1) 2750 = 550 + 125x

2) subtract 550 from each side

2750-550=2200

so the left over equation is:

2200 = 125x

3) divide each side by 125 to get x by itself

2200÷125= 17.6

4) you are left with: x = 17 days
