Answer:
50 pages
Step-by-step explanation:
We can set up an equation for this in slope-intercept form.
The slope is 2 due to her expecting to write 2 pages an hour.
The y-intercept is 2 because she has already written 2 pages.
The full equation is y = 2x + 2.
We can plug 24 in for x to get y = 48 + 2, which simplifies to y = 50.
Answer:
x = 348
Step-by-step explanation:
The measure of angle ABD is (0.15x+65) and the measure of angle CBD is(0.1x+28) . Find the value of x.
0.15x + 65 + 0.1x + 28 = 180
0.25x + 93 = 180
0.25x = 180 - 93
0.25x = 87
x = 87/0.25
x = 348
