Answer:

Step-by-step explanation:

(4,1/3) and has a slope of 3/4

y - y1 = m(x - x1)

m = 3/4, y1 = 1/3, x1 = 4

y - 1/3 = 3/4(x - 4)

Multiply each term by 12

12y - 4 = 9x - 36

12y = 9x - 36 + 4

12y = 9x - 32

Answer:

\boxed{\sf \huge \boxed{ \sf ?} = 6}

Step-by-step explanation:

\sf Solve  \: for \: \boxed{ \sf ?} :  \\  \sf \implies \frac{\boxed{ \sf ?}}{5}  \times  \frac{10}{8}  = 1.5 \\  \\  \sf  \implies \frac{\boxed{ \sf ?} \times 10}{5 \times 8}  = 1.5 \\  \\  \sf \frac{10}{5}  =  \frac{ \cancel{5} \times 2}{ \cancel{5}}  = 2 :  \\  \sf \implies  \frac{ \boxed{ \sf 2} \times \boxed{ \sf ?} }{8}  = 1.5 \\  \\  \sf \frac{2}{8}  =  \frac{ \cancel{2}}{ \cancel{2}  \times 4}  =  \frac{1}{4}  :  \\  \sf \implies \frac{\boxed{ \sf ?}}{ \boxed{ \sf 4}}  = 1.5 \\  \\  \sf Multiply  \: both  \: sides \:  of \:  \frac{\boxed{ \sf ?}}{4}  = 1.5 \: by \: 4 :  \\  \sf \implies \frac{4 \times \boxed{ \sf ?}}{4}  = 4 \times 1.5 \\  \\  \sf \frac{4 \times \boxed{ \sf ?}}{4} =  \frac{ \cancel{4}}{ \cancel{4}}  \times \boxed{ \sf ?} = \boxed{ \sf ?} :  \\  \sf  \implies \boxed{\boxed{ \sf ?}} = 4 \times 1.5 \\  \\  \sf 4 \times 1.5 = 6 :  \\  \sf \implies \boxed{ \sf ?} = 6

What number is 24% of 80
jonny [76]
Hi

24% of 80 is 19.2

100% ⇒ 80
24% ⇒ x 

100x = 24·(80)
100x = 1920
x = 1920/100
x = 19.2

(-10x)(2) is there any chance you can help please and thanks
Svetllana [295]
The answer is -20x, because the parentheses show they are being multiplied, so you multiply -10x and 2, which would be -20x.
