Answer:
a. <u>saletax</u><u> </u>= 98.75
100
<u>5</u><u> </u> = <u> </u><u>9</u><u>8</u><u>.</u><u>7</u><u>5</u>
100 1
we cross multiple
5(1) = 100(98.75)
5 = 100(98.75)
<u> </u><u> </u>divide both side by 5
<u>5</u><u> </u><u> </u>= <u> </u><u>1</u><u>0</u><u>0</u><u>(</u><u>9</u><u>8</u><u>.</u><u>7</u><u>5</u><u>)</u>
5 5
since 100 can divide 5 so we divide them
= 20(98.75)
amount sale tax = 1975
b. 98.75 × 5 =493.75$
Answer:
-6
Step-by-step explanation:
is -6
Answer:
w = 62m
Step-by-step explanation:
We need to make an expression for the numbers of words (w) John types in m minutes.
We know he types 62 words in 1 minute, so 62 is the coefficient of m.
The dependent variable here is w, so that should on the left of the equal sign.
m, on the other hand, is independent, so that's on the right of the equal sign.
So, the expression is w = 62m.
Answer:
-4
Step-by-step explanation:
This looks like point-slope form, which I find personally hideous. Let's change it to slope-intercept form to ease my conscience. (remember that slope-intercept form is y=mx+b, where m=slope and b=y-intercept!)
y - 5 = -4(x-8)
y - 5 = -4x + 32
y = -4x + 37
It's in slope-intercept form now! And -4 looks to be our m.
<u>So the slope is -4.</u>
