Answer:
543.2 miles
Step-by-step explanation:
Input the given value of x into the equation and solve for y:
y = -67.9x + 679
y = -67.9(2) + 679
y = -135.8 + 679
y = 543.2
The total distance in miles after 2 hours is 543.2 miles.
Answer:
30
Step-by-step explanation:
Answer:
v = 2,325,457
Step-by-step explanation:
f×v= 13,573,692,509
5837×v= 13,573,692,509
v = 13,573,692,509÷5837
v = 2,325,457
A ratio is a mathematical comparison of two numbers, based on division. For example, suppose you bring 2 scarves and 3 caps with you on a ski vacation. Here are a few ways to express the ratio of scarves to caps
The simplest way to work with a ratio is to turn it into a fraction. Be sure to keep the order the same: The first number goes on top of the fraction, and the second number goes on the bottom.
In practice, a ratio is most useful when used to set up a proportion — that is, an equation involving two ratios. Typically, a proportion looks like a word equation, as follows:
For example, suppose you know that both you and your friend Andrew brought the same proportion of scarves to caps. If you also know that Andrew brought 8 scarves, you can use this proportion to find out how many caps he brought. Just increase the terms of the fraction
<h2> </h2>
so that the numerator becomes 8. Do this in two steps:
As you can see, the ratio 8:12 is equivalent to the ratio 2:3 because the fractions
are equal. Therefore, Andrew brought 12 caps

Answer:
Step-by-step explanation:
I think the first term is -9.
Then each term is 4 more than the previous term.
The constant difference is 4. d = 4.
For n ≥ 2,
