x-7>10
x>__?
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:
y int.=5
slope=-7/4
Step-by-step explanation:
-7x-4y=-20
+7x +7x
-4y=7x-20

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

solve this equation x/4-20=-12
Answer:
X=32
Step-by-step explanation:
First Find common denominator
Combine fractions with common denominator
Multiply the numbers
Multiply all terms by the same value to eliminate
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!
What is the measure of angle ABE?
Please provide an explanation to your answer, thank you.
Answer:
50°
Step-by-step explanation:
According to the vertical angle theorem, two opposite vertical angles formed when two lines intersect each other are always equal (congruent) to each other.
This would mean CBD is equal to ABE which means ABE would be 50°.

Pls solve the right way then I’ll give you 15pts
Answer:
x=27
Step-by-step explanation:
Aight so the angle of line AB equals 180 degrees. You have 36 degrees plus the right angle (90 degrees) which gets you 126 degrees. Subtract 126 from 180 and you get 54, the remaining value. So if 2x=54, then divide both sides by 2 to get x=27. that should be it

What is the length of DE
A. 18
B. 12
C. 10
D. 22
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!

One week, Sharon worked 18 hours as a lifeguard and 12 hours at a concession stand and earned $228. The next week, she earned $254 for 24 hours as a lifeguard and 8 hours at the concession stand. How much per hour does she get paid for each job?
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.

Fill in the function table: y = -2(x - 1)
please help
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

I need help on the whole assignmnet but particularly this question..
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.
what is the slope of all lines parallel to the line 4x-5y+-1?
a -5/4
b 5/4
c-1/5
d4/5
Given equation of the line ,
[tex]\implies 4x - 5y +(-1) = 0 [/tex]
Simplify ,
[tex]\implies 4x - 5y - 1 = 0 [/tex]
Transpose terms to RHS ,
[tex]\implies 5y = 4x - 1 [/tex]
Divide both sides by 5 ,
[tex]\implies \boxed{ y =\dfrac{4}{5}x -\dfrac{1}{5}}[/tex]
Now we know the slope intercept form of the line as [tex] y = mx + c [/tex] we have ,
[tex] m =\dfrac{4}{5}[/tex]As we know that the slope of all parallel lines are same . Henceforth ,
[tex] m_{|| \ lines } =\dfrac{4}{5}[/tex]A bike shop sells bikes for $155 each and scooters for $65 each. Write an equation to represent the cost of 2 scooters and x number of bikes.

5. For which value of x is line 1 parallel to line m? (1 point)
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
C: Joe is a waiter.
Last night he made
$37 in fips and
makes $8.50 per
hour. How much did
he make after his 8
hour shift?
Answer:
8x8.5 +37
68+37 = 105
$105 dollars for an 8 hour shift
$68 salary + $37 tips = $105
Answer:
total wage in 8 hrs = $105
Step-by-step explanation:
37 + (8 * 85) = 37 + 68 = $105 we simply do the maths without decimal then place on the 10's =(8 * 85) = 680 = $68 then add the $37 = $105
