Answer:
The sides are 24cm, 7cm, and 25cm
Step-by-step explanation:
3x+x-1+3x+1=56 <---- First we combine like terms (the 1's cancel out)
7x/7=56/7 <--- Divide by 7 to isolate the variable
x=8 <--- Now that we've solved for x we need to plug it back into each side
3(8)=24
(8)-1=7
3(8)+1=25
24+25+7=56 <---- Make sure it all adds up to 56
Hope this helps :)
Answer:
that would be b
Step-by-step explanation:
He will run 20miles for 10 minutes
Rate = Distance / time
for the first jog
distance = 8 miles
time = 4 minutes
rate = 8 / 4
rate = 2 miles/minutes
to calculate the distance covered in 10 minutes
from Rate = distance / time
Introducing cross multiplication
Distance = rate x time
Distance = 2 x 10
Distance = 20miles
Points Q and R. Their coordinates are R=(-5,-7), Q=(-5,6). The first number is the X-intercept. Both Q and R have -5 have -5 as their first number. You can tell this by drawing two line from the x-axis (horizontal) and the y-axis (vertical) and see where they meet up. See what numbers the coordinates are, and presto, you have your answer!
Hope that help!
