Answer:
x = 10
Step-by-step explanation:
First, distribute:
Next, subtract from both sides:
(multiply by 2 to get common denominator, )
Next, subtract from both sides:
(multiply by 2 to get common denominator, )
⇒
Next, multiply both sides by 10:
FInally, divide both sides by -1:
x = 10
Answer:
E) 79.7 cm^2
Step-by-step explanation:
This is really messy so I think the choices are A) to E) only
I think its 6cm 7.2cm 2.8cm 10cm
1. Multiply all
6 * 7.2 + 2.8 * 10 > 70
2. Around 79.7
Y Could be any number. Like
<em>Y x 5 = 10 The answer is 2</em> because <u>10 / 5 = 2</u>
<em>But Y could be 10 in Y x 2 = 20</em>
To solve a proportion, you can either use cross products or basic multiplication.
To do cross products, you would multiply 17 (1st numerator) by 6 (2nd denominator).
Do the same with the other diagonal angle, 3 times y.
You'll end up with 3y = 102.
To solve for y, you divide both sides by 3.
102 ÷ 3 = 34
y = 34
The other way you could solve this is to see that 6 is 2 times as large as 3, so you would multiply 17 by 2 to get an equal proportion.
3 × 2 = 6
17 × 2 = 34
Your final answer is y = 34. Hope this helps! :)
Answer:
Step-by-step explanation:
Volume of cylinder is given as
V is the volume the cylinder, r is its radius at the base, while is its height.
To select the formula for h (height) let's make h the subject of the formula as follows:
(dividing both sides of the equation by )
Use the formula above to find the height of the given cylinder where Volume (V) = 36π cm³, and base radius (r) = 3 cm:
(substitution)
( cancels )
