Answer: <em>x </em>= 13
Step-by-step explanation: the equation to solve this is:
4 × (4 + 8) = 3 × (3 + <em>x</em>)
so we solve the first half of that:
4 × (4 + 8)
4 × 12
48
now we have:
48 = 3 × (3 +<em> x</em>)
so we switch the sides to make it easier and solve
3 × (3 + <em>x</em>) = 48
divide both sides by 3
3 × (3 + <em>x</em>) ÷ 3 = 48 ÷ 3
and get
3 +<em> x</em> = 16
now subtract 3 from both sides
3 + <em>x</em> = 16
-3 -3
and finally we get
<em>x </em>= 13
hope this helped :)
Acording to Newton's 3 Laws
1) Jason: Shop A - 11 units; Shop B - 12 units. Sales increase at 17% per week. So, 11 + 12 = 23.
f(x) = 23(1.17)ˣ
2) Daniel: Element A temp - 44(1.13)ˣ ; Element B temp - 17(1.13)ˣ. How much temp of Element A be more than the temp of Element B.
f(x) = 44(1.13)ˣ - 17(1.13)ˣ = 27(1.13)ˣ
f(x) = 27(1.13)ˣ
3) Maggie: Tshirt price - $13. Charity donation - 270
f(x) = 13x - 270
4) Mr. Smith: Length of backyard - 30x + 29 ; Length of square patio - 13x + 6
Length not covered by the patio.
f(x) = (30x + 29) - (13x + 6) = 30x - 13x + 29 - 6 = 17x + 23
f(x) = 17x + 23
Dividing fractions is basically the same thing as multiplying but by the reciprocal. I will give an example.
1/2 divided by 1/3
To solve this you do 1/2 multiplied by 3/1 so you switch the numerator and denominator.
