Answer:
Step-by-step explanation:
Expand -(1/5)-x+2+3
-(1/5)-x+2+3
Remove the parenthesis;
=1/5-x+2+3
Add the numbers; 2+3=5
=-x+5-1/5
Convert element to fraction;
=5*5-1/5
Since the denominators are equal combine the fractions;
5*5/5-1/5
5*5-1=24
Multiply the numbers;5*5=25
=25-1
Subtract the numbers:25-1=24
=24
=-x+24/5
-12x+26=-x+24/5
Subtract 26 from both sides;
-12x+26-26=-x+24/5-26
Simplify;
-12x+26-26
Add similar elements; 26-26=0
=-12x
Simplify;-x+24/5-26
Convert element to fraction;
- 26/*5/5+24/5
Since the denominators are equal , combine the fractions;
-26*5+24
Multiply the numbers; 25*5=130
=-130+24
Add/subtract the number;-130+24=-106
=-106
=-106/5
Apply the fraction rule;
=-x-106/5
-12x=-x-106/5
Add x to both sides;
-12x+x=-x-106/5+x
Simplify;
-11x+=-106/5
Divide both sides by -11
-11x/-11=-106/5/-11
Simplify ;-11x/-11
Divide ;11/11
=1
=x
simplify;-106/5/-11
Apply fraction rule; 106/5/11
106/5*11
Multiply the numbers;5*11=55
=106/55
x=106/55
given X= -7 what is the value of the following expression 4(X-5)+2
Answer: -46
Step-by-step explanation: Place -7 into the equation. 4(-7-5)+2= 4*-7=-28,-4*5=20. Negative 28 minus 20 is -48. Negative 48 + 2 is -46.

Please halp I need to finish my homework by Monday and I haven’t been able to finish it so please halp! The question is 9x3/4!!!
Answer:
Step-by-step explanation: 6.75
Help please I will give you the brainliest
Answer:
x=15 degrees
Step-by-step explanation:
You know that the right angle is split in half to 45 degrees and 3x degrees. Because a right angle is equal to 90 degrees, 3x has to be equal to 45. Therefore, the equation will be 3x=45. You want to make x equal one so you have to divide 3 by each side. The equation will be x=45/3. Simplify that to get x=15. Therefore, x=15 degrees.

Eight more than seven times a number is -20
Answer: The number is 0
Step-by-step explanation:
8 = 7x + 8
Then we solve it:
8 = 7x + 8
8 - 8 = 7x
0 = 7x
0 ÷ 7 = x
x = 0
hope this helps have a nice day
Scarlett and Alyssa work at a dry cleaners ironing shirts. Scarlett can iron 15 shirts per hour, and Alyssa can iron 35 shirts per hour. How many total shirts would be ironed between the two workers if Scarlett worked 5 hours and Alyssa worked 10 hours on a given day? How many total shirts would be ironed between the two workers if Scarlett worked x hours and Alyssa worked y hours on a given day?
Answer:
25x + 35(2x) = 380
25x + 70x = 380
95x = 380 so
x = 4
then i think that mean it might be 8 then im not completly sure
1) What is the surface area?
1 ft
8 ft
4 ft
Answer:
88 ft^2
Step-by-step explanation:
For a rectangular prism with dimensions 1 ft by 8 ft by 4 ft, there are two opposite faces with dimensions
1 ft by 8 ft,
two opposite faces with dimensions
1 ft by 4 ft,
and two opposite faces with dimensions
4 ft by 8 ft.
We find their area and add them.
SA = 2 * 1 ft * 8 ft + 2 * 1 ft * 4 ft + 2 * 4 ft * 8 ft
SA = 16 ft^2 + 8 ft^2 + 64 ft^2
SA = 88 ft^2

L.C.M of x2 + 3x + 2 and x2 + 4x + 3
Answer:
Step-by-step explanation:
x^2 + 3x + 2 = (x+1)(x+2)
x^2 + 4x + 3 = (x+1)(x+3)
LCM = (x+1)(x+2)(x+3) = (x^2 + 3x + 2) (x+3) = x^3 + 6x^2 + 11x + 6
Step-by-step explanation:
1st expression
x2 + 3x + 2
x²+2x+x+2
x(x+2)+1(x+2)
(x+2)(x+1)
2nd expression
x2 + 4x + 3
x²+3x+x+3
x(x+3)+1(x+3)
(x+3)(x+1)
L.C.M=(x+1)(x+2)(x+3)

Write in equation passing through the point that is parallel to (8,3); y=-1/4x+7
Answer:
y=-1/4x+5
Step-by-step explanation:
Use the point-slope form which is y-y1=m(x-x1) where m is the slope. In this case, y is equal to 3, and x is equal to 8, and the slope is equal to -1/4. Therefore, the equation will be equal to y-3=-1/4(x-8). Simplify that to get y-3=-1/4x+2. Simplify this again to get y=-1/4x+5. Therefore, the equation is y=-1/4x+5.
Answer:
y = -1/4x + 5
Step-by-step explanation:
Since the lines are parallel, they have the same slope, which is -1/4
Use the point-slope form to do this problem
[tex]y - y_{1} = m(x - x_{1})[/tex] Memorize this form. OK?
y - 3 = -1/4(x - 8)
4y - 12 = -1(x - 8) = -x + 8
4y = -x + 20
y = -1/4x + 5

What is the value of x? Pls help
Answer:
x=20
Step-by-step explanation:
ok so that is a pentagon and if you didnt know all of the angles in a pentagon add up to equal 540
so we setup an equation which would be
7x+4x+5+4x+10+5x-5+6x+10=540 and now we just solve for x
step 1 combine like terms
7x+4x=11x
11x+4x=15x
15x+5x=20x
20x+6x=26x
5+10=15
15-5=10
10+10=20
now we have
20+26x=540
step 2 subtract each side by 20
20-20 cancels out
540-20=520
now we have 26x=540
the final step is to divide each side by 26
26/26 cancels out
540/26=20
x=20
hope this helps :D

help me please this will help my grade !
Answer:
the answers B and D are correct
Answer:
B & D
Step-by-step explanation:
It can-t be A, because that would mean 20², which equals 400, would equal 20.
B is correct because even though it's negative, negative times negative = positive, which would mean that (-sqrt of 20)(-sqrt of 20)=20.
C is wrong because sqrt -20 is an imaginary number,which is a completely different topic.
D is correct because it's the same thing as B, but without the 2 negaties cancelling each other out.
E is the same as A, except it's '-20' x '-20', whcih is still 400, which is still wrong
Hope this helps :)
Sarah is having people over for her birthday party. If she orders 4 pizzas for 15 people, how many should she order for 30 people?
Answer: 8
Step-by-step explanation:
Answer: 8 pizzas.
Step-by-step explanation:If she is ordering 4 pizzas for 15 people then that simply means that the fraction is 4/15, 15*2 is 30, so that means that our next fraction (Equivalent fraction) will be like this 4/15 = -/30. What ever. Happens to the numerator must happen to the denominator and vice versa. So 4*2 is 8. So the answer is 8.
