Answer:
x=9
Step-by-step explanation:
Corresponding angles are equal
7x - 3 = 60
+3
7x. = 63
÷7
x = 9
Check:
7x9 - 3 = 60
Hope this helps!
The answer is = because of you take away the 0 in the decimal 8.250 it's the same decimal as 8.25 and in decimals the zeros farthest to the right don't matter.
8.25 = 8.250
If a circle has radius
R, its circumference equals to
2πR where π is an irrational number that, approximately, equals to
3.1415926
The answer is 7x = 6(x + 15)
x - Jim's rate
y - Pete's rate
<span>Jim completed half the floor in 7 hours: 7x = half of the floor
</span><span>Pete completed the other half of the floor in 6 hours: 6y = half of the floor
So: 7x = 6y
</span><span>Pete can lay 15 more tiles per hour than Jim: y = x + 15
</span>7x = 6y
y = x + 15
Substitute the second equation into the first one:
7x = 6(x + 15)
