<em>Let's set up an equation</em> to figure this out!
<u>"ten more"</u> means we need to put + 10 in the equation
<u>"than a number"</u> can be represented by x
x + 10 = -122
Solve!
x = -122 - 10
x = -132
The answer is -132
Answer:
they multiplied all the sides
Step-by-step explanation:
This is direct proportion - it takes less time to run 15 miles than 50 miles. Show the comparison:
<span><span>5060</span>=<span>15x</span></span>
<span>50x=60×15</span>
<span>x=<span><span>60×15</span>50</span></span>
<span>x=18</span>minutes
Answer:
Let's start with part B. if it was originally 10 cm tall and it goes up 0.5 cm. each day, then we know that to go up one cm it needs two days. With that information we can say that 8*2 = 16. So it needs 17 days to go up 8.5 cm which would make it 18.5 cm tall.
Step-by-step explanation:
f(x) = 0.5x + 10
0.5x + 10 = 18.5
0.5x = 18.5 - 10
0.5x = 8.5
x = 8.5/0.5
x = 17 days
The answer is:
-20a+24b-40c+12
