If 200% of 40% of x is equal to 40% of y, then x is what percent of y?

Mathematics

sp2606 [1]3 years ago
3 0

Step-by-step explanation:

200÷100×40÷100× x = 40÷100 × y

2×0.4 × x = 0.4 × y

2x = y

x = y × 1÷2

x = y × 50%

Complete the equation for the linear function whose graph contains the point (-1,2) and has a slope of 0.9.
Mnenie [13.5K]
Plug it into point-slope form.

y - y1 = m(x - x1)

Where y1 is the y-value of the point, x1 is the x-value, and 'm' is the slope.

So plug in -1 for x1, 2 for y1, and 0.9 for 'm':

y - 2 = 0.9(x + 1)

Simplify to get in slope-intercept form:

Distribute 0.9 into the parenthesis:

y - 2 = 0.9x + 0.9

Add 2 to both sides:

y = 0.9x + 2.9

makvit [3.9K]

Answer:

Parent's share would be : 28%

Step-by-step explanation:

Cost of the computer = $2000

Anya's share = $1200

Brother's share = $240

Parents paid rest. That will be : 2000 - 1200 - 240 = $560

Percentage of parents share :

                                             \frac{560}{2000} \times 100 = 28 \%
