1. 504=3x
x=168
2. 64=20m
m=3.2
Answer:
the answer has to be 3(17-y)
Step-by-step explanation:
I'm pretty sure about that cause what I did at first is subtract the numbers.
<em>6</em><em>0</em><em>-3y-9</em>
=51-3y
factor our 3 from the expression.
3(17-y)
Answer:
4 minutes 3 seconds
Step-by-step explanation:
Step one:
Given data
A kangaroo hops 2 kilometers in 3 minutes
The rate/speed is
rate/speed= 2/3 km per minute
Required
the time taken to cover 3 km
Step two:
We know that
rate= distance/time
2/3= 3/t
cross multiply we have
2t=3*3
2t=9
divide both sides by 2
t= 9/2
t= 4.5 minutes
t= 4 minutes 3 seconds
Angle 6 and Angle 7 are each 90° since they’re on a straight line and are both equal.
180-90= 90
*you subtract from 180 because that’s how many degrees are in a straight line*
Angle 7 and Angle 1 are alternate exterior angles so that makes them congruent by definition.
Answer:
B
Step-by-step explanation:
Let the base of the triangle be <em>b</em> and the height be <em>h</em>.
The sum of the base and height is 14. Thus:
Recall that the area of a triangle is given by:
From the first equation, solve for either variable:
Substitute:
Distribute:
Distribute:
Let <em>b</em> = <em>x</em>. Hence:
Therefore, our answer is B.
