When solving these proportions we just remember when moving a number from one side to the other if it started in the numerator it ends up in the denominator and vice versa.

I'll do it in two steps here for teaching purposes; it's not too hard to go directly to the answer.

$\dfrac{13}{7} = \dfrac{10}{v}$

$13 v = 7(10)$

$v= \dfrac{7 \cdot 10 }{13} = \dfrac{70}{13} \approx 5.4$

40 is 120% of what number?

Dennis_Churaev [7]

Always remember that percent means "out of 100". That means the 40%=40/100=.4
so 40% of 120 is equivalent to .4(120)=48
Hope I helped

If h(x) = 4x – 3 and p(x) = x2 – 3x, find p(-3) 18 0 -3

navik [9.2K]

Answer: p(-3)=18

Step-by-step explanation:

To find p(-3), you plug -3 into p(x) and solve.

p(-3)=(-3)²-3(-3) [exponent]

p(-3)=9-3(-3) [multiply]

p(-3)=9+9 [add]

p(-3)=18

Now we found that p(-3)=18.
