Answer:
20 miles
Step-by-step explanation:
to find how many miles she travels in one hour, multiply by 2 to get 10, and then multiply it by 2 again to find 2 hours
Answer:
20 miles
Step-by-step explanation:
To find out how many miles can be ridden in 2 hours, multiply 1/2 and 5 by 4 to get both answers like so:
1/2 (4) = 2 HOURS
5 (4) = 20 MILES
Therefore, Susan can ride her bike 20 miles in 2 hours.
2. Expand the brackets and simplify:
a) X(2x + 3)
Answer:
2x^2 +3x
Step-by-step explanation:
X(2x + 3)
Distribute
2x*x + 3x
2x^2 +3x
Answer:
B
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 5 and (a, b) = (2, - 7), thus
y - (- 7) = - 5(x - 2) , that is
y + 7 = - 5(x - 2) → B
Answer:
They do form a proportion.
Step-by-step explanation:
To determine whether the two rates form a proportion, you can set up a proportion and check if the cross-products are equal.
The two rates you have are:
Rate 1: 7 inches in 9 hours
Rate 2: 42 inches in 54 hours
You can set up a proportion like this:
Rate 1 (inches per hour) / Rate 2 (inches per hour) = Time 1 (hours) / Time 2 (hours)
So, it becomes:
(7 inches / 9 hours) / (42 inches / 54 hours)
Now, let's calculate these fractions:
Rate 1 (inches pr hour) = (7 inches / 9 hours) ≈ 0.7778 inches per hour (rounded to 4 decimal places)
Rate 2 (inches per hour) = (42 inches / 54 hours) ≈ 0.7778 inches per hour (rounded to 4 decimal places)
Now, compare the two rates (rounded to 4 decimal places):
Rate 1 ≈ 0.7778 inches per hour
Rate 2 ≈ 0.7778 inches per hour
Since both rates are approximately equal to 0.7778 inches per hour, they do form a proportion. When two rates are in proportion, their ratios are equal, which is the case here.
