In a race, a bicyclist travels 3/4 of a mile in 1/4 hour. Determine the unit rate for the speed in miles per hour.
5/2 miles per hour
(3/4÷1/4)=3 miles per hour☆☆☆☆☆☆☆
41/4 miles per hour
4 miles per hour
Step-by-step explanation:
Given the expression:

Follow BODMAS rule.
always evaluate brackets first, followed by multiply or division then addition or subtraction from LEFT to RIGHT.

Answer:
y=-4x+9
Step-by-step explanation:
a line parallel to another line means the two lines have the same slope
so you can already cross out the second and last equation
the y-intercept is 9 so it is positive, not a negative 9
5x+10=25
5 divides into all the number to simplify to 3 plug in 3 into the x value then to multiply 5 and 3 which is 15 than add to to equal 25
I showed my work and answer in this picture. When simplifying square roots you can split them into a perfect squares root time the remainders
