And I think you got it from there :))))))))))))))

Answer:

x = 32

Step-by-step explanation:

Find a common denominator

x/4 + 4 ( -20 )/4 = -12

Combine fractions with denominator

Multiply the numbers

Multiply all terms by the same value to eliminate fraction denominators

Cancel multiplied terms that are in the denominator

Multiply the numbers

Add 80 to both sides of the equation

Then simplify!

1/7^-2 is equal to 7^-2*-1 making it 7^2 which is equal to 49.

Answer:

X=12.75

Y=12

Step-by-step explanation:

4X+8°+31°=90°

4X=90-39/4°

X=12.75°

3Y+86=8Y+26

86-26=8Y-3Y

60=5Y

Y=60/5

Y=12

Answer:

x = 12.75

y = 12

Step-by-step explanation:

To solve for x, we can see that it makes up a right angle when placed next to the 31 degrees.

We also know that the corner should equal 90 degrees, so we can set this up:

4x+8+31=90

Group like terms:

4x=51

Divide:

x=12.75

To solve for y, we can see that two expressions equal the same length, so:

8y+26=3y+86

Group like terms:

5y=60

y=12

You can also plug in x and y in to see if they match up

4(12.75)+8+31=90

51+8+31=90

90=90

and

8(12)+26=3(12)+86

96+26=36+86

122=122

we first substitute the x

y= -2(-2-1)

=6

and then use a calculator to do the sum

which gives us 6

y= -2(-1-1)

= 4

y= -2(0-1)

=2

y= -2(1-1)

=0

y= -2(2-1)

=-2

Answer:C

Step-by-step explanation:

Answer:

f=-2.75

Step-by-step explanation:

2(f-2)=3(2f+5)-8

2f-4=6f+15-8

2f-6f=7+4

-4f=11

f=-11÷4

=-11/4=-2/3/4=-2.75

Answer: -15

Step-by-step explanation: 2r+8-r=-7

1r +8 = -7

1/1       -15/1

Answer: r = -15

Step-by-step explanation:

2r - r = -7 -8

r = -15

Answer:

None of the above

Step-by-step explanation:

Notice the wording "which of the following statements MUST VE TRUE..."

From the figure, we see that two angles with vertex S are congruent to two angles with vertex at Q.

There is no indication the two angles at S are congruent. There is no indication the two angles at Q are congruent.

We are not told anything about angle measures.

Answer: None of the above

Answer:

Answer: 62

Step-by-step explanation: you set up the equation by making the two sums equal eachother. 2x+6=130. then you solve, subtract six from both sides, then you have 2x=124. divide both sides by 2 to get the sum of x. you get x=62

Answer:

the length of DE is A) 18

Step-by-step explanation:

these triangles are similar so you need to create a proportion!

since sides DF and FE are the same, it means that AC and CB are the same!

now we have to find the hypotenuse for DE, which is X

- set up a proportion!

side AC/side AB = side DF/side DE ----> 15/27 = 10/x

- butterfly multiply to get 15x = 270

- divide both sides by 15 to isolate x

now you get --------> x = 18!

Answer:

[tex]x>17[/tex]

Step-by-step explanation:

We can treat an inequality just the same as an equality in terms of manipulation!(This doesn't hold for multiplying or dividing by negative numbers, but it holds for all addition).

So, we can add [tex]7[/tex] to both sides of the inequality to get [tex]x-7+7>10+7[/tex].

We can simplify [tex]-7+7[/tex] into [tex]0[/tex], and [tex]10+7[/tex] into [tex]17[/tex].

So, the answer is [tex]\boxed{x>17}[/tex] and we're done!

Answer: 1 2/3

Step-by-step explanation:

Answer:

1) 62.5

2) 50

3) 75

4) 100

Step-by-step explanation:

1)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After [tex]25*4=100[/tex] days, there will be [tex](1/2)^{4}=1/2^{4}=1/16[/tex] of it left.

So, [tex]1000/16=\boxed{62.5}[/tex].

2)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After [tex]25*3=75[/tex] days, there will be [tex](1/2)^{3}=1/2^{3}=1/8[/tex] of it left.

So, [tex]400/8=\boxed{50}[/tex]

3)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After [tex]25*2=50[/tex] days, there will be [tex](1/2)^2=1/2^{2}=1/4[/tex] of it left.

So, [tex]300/4=\boxed{75}[/tex].

4)

The only answer left is [tex]\boxed{100}[/tex] grams. You can solve it the same way you solved the previous steps.

Answer:

She is paid $6.25.hour at the concession and $8.50 as a lifeguard.

Step-by-step explanation:

We know:

18 hours as a lifeguard

12 hours at concession

Total earned = $228

18L + 12C = 228

Then:

24 hours as a lifeguard

8 hours at concession

Total earned = $254

24L + 8C = 254

Move one equation around to get one variable by itself: in this case we can solve for L:

18L + 12C = 228

18L = 228 - 12C

L = (228/18) - (12/18)C

Plug in for L:

24((228/18) - (12/18)C) + 8C = 254

Solve for C:

C = 6.25

Now that we know C, plug in value for C and solve for L:

18L + 12(6.25) = 228

L = 8.5

So she is paid $6.25.hour at the concession and $8.50 as a lifeguard.
