Step-by-step explanation:
what is this 2x-5+22=?
Answer: 2x+17
Step-by-step explanation: add -5 and 22
______________________________
1.) Add −5 and 22:[tex]-5+22=17[/tex]
- You could also solve this by flipping the numbers around and subtracting 22 - 5, Which still gives you 17.
So your answer is [tex]\bold{(2x+17)}[/tex].

Does anyone know how to do simple interest for 7th grade math? I need a tutorial or an example please, thanks. A question example is $750, 7%, 3 years.
Answer:
750/100 X 7 = 52.50
52.50 X 3 = $157.50
Step-by-step explanation:
divide principal amount by 100 then multiply by interest percentage. this gave 52.50
now multiply the interest amount by number of years
in this case 3
52.50 X 3 = $157.50
simplify each expression 6X + 2x
Reasoning A cylindrical water tank holds 26 litres when full. The water tank is 36 cm tall.
Work out the radius of the tank to 2 d.p.
(4 marks)
Answer:
r = 15.16 cm
Step-by-step explanation:
Mathematically, we need a consistent unit
26 liters = 26,000 cm^3 as 1000 cm^3 = 1 L
The volume of a cylinder is;
V = pi * r^2 * h
26,000 = 3.142 * r^2 * 36
r^2 = 26,000/(3.142 * 36)
r^2 = 229.86
r = √229.86
r = 15.16 cm

Answer:
k=-13
Step-by-step explanation:
If f(x)= -2x+3 , find f(-1)?
Before we solve the equation let's take a look at it.
f(x) = -2x + 3
See how x appears in both f(x) and as the variable in the second half of the equation?
f(x) means "The function of x." You might also see g(x), h(x), and while those are the most common it can really be any letter, and any variable inside the parentheses.
So when we see f(-1), that means "The function of -1" or "The function of x when it is equal to -1."
Catching on? We need to replace x with -1 to solve for f(-1).
So here we go:
f(x) = -2x + 3
f(-1) = -2(-1) + 3
f(-1) = 2 + 3
f(-1) = 5
Voilà! We have solved for f(-1). Hope this helped.
Write down the size of angle ABC.
Give a reason for your answer.
Answer:
Angle ABC = 90°
Step-by-step explanation:
Angle AOC= 180°
so Angle ABC = 0.5 x AOC
or another way to explain is
Rule 1: Angles in semi circle are always 90°

Enter the numerator that makes the equation true.
1 3/4 + 1 1/3 = 1 _/12 + 1 4/12
The '_' is blank.
Answer:
1 3/4
Step-by-step explanation:
First write the equation in mixed fraction form as;
1 3/4 + 1 1/3 = 1 _/12 + 1 4/12 ⇒ 7/4 + 4/3 = _ + 16/12
7/4 + 4/3 = _ + 16/12
37/12 = _ + 16/12
37/12 - 16/12 = _
= 21/ 12
= 1 9/12
= 1 3/4
need help with this please
Answer:
13.6
Step-by-step explanation:
Remember SOH CAH TOA
We're going to use tangent = opposite / adjacent because the 11 is opposite theta (39 degrees) and x is adjacent to it.
tan (39) = 11 / x
x = 11 / tan(39)
x = 13.584 -> 13.6 (rounded to nearest tenth)
Note: Make sure your calculator is in degree mode.
Which electric circuit arrangement will light the bulb?
Answer: Both the metal casing and tip of the bulb are connected to the circuit, forming a closed circuit. Thus, electricity is able to flow through the wires in the circuit to the filament, allowing the bulb to light up.

Monday Bellwork Which solution would make this equation have infinitely many solutions? 6(x – 3) + x = 7x +
-18, -9, 18, or 9
Answer:-18
Step-by-step explanation:
6(x−3)+x=7x−18
Step 1: Simplify both sides of the equation.
6(x−3)+x=7x−18
(6)(x)+(6)(−3)+x=7x+−18(Distribute)
6x+−18+x=7x+−18
(6x+x)+(−18)=7x−18(Combine Like Terms)
7x+−18=7x−18
7x−18=7x−18
Step 2: Subtract 7x from both sides.
7x−18−7x=7x−18−7x
−18=−18
Step 3: Add 18 to both sides.
−18+18=−18+18
