Bill earned $12 walking his neighbors' dogs on Saturday. He earned some extra money on Sunday doing the same thing. Write an exp
Tems11 [23]
Answer:
Part A: 12 + X
Part B: 25 + 2
Step-by-step explanation:
First thing you need to know is the
difference between an expression and an
equation. An expression does not have an
equal sign, while an equation does.
To write an expression for Part A, first write
the 12 (the amount he got on Saturday).
Then, we need to write the addition sign (to
find the total amount Bill earned). We don't
know how much Bill earned on Sunday, so
use any variable (I used x). Because we're
writing an expression, do not write an
equal sign.
To write an expression for Part B, first write
the amount of dogs his friend Steve walked
using a variable because we don't know
that number (I used the variable s). Then,
since Bill walked 2 more than twice as
many dogs Steve walked, write the s
multiplied by the 2 or just 2s. Now add the
addition sign (to find the total amount Bill
walked). Add a 2 because Bill walked 2
more dogs than twice as many Steves walked.

Hope it helps!

Solve open parentheses square root of 7 close parentheses to the 6 x power = 49x−6.
LUCKY_DIMON [66]
(sqrt7)^6x = 49x - 6

There is no easy way to solve this . Drawing a graph will give a good approximation.

Draw  y = (sqrt7)66x

and y = 49x - 6     and see where they intersect

Ill draw it on desmos graphing tool and give you the link.

a bowling ball has a diameter of 8.5 inches. If it is rolled down a 60-foor bowling lane, how many complete revolutions will it
Tatiana [17]
We know that
A bowling lane<span> is 42 inches wide and </span>60 feet<span> long
1 ft-------> 12 in
60 ft-----> X
X=60*12------> X=720 in
</span>
[the length of a circumference]=2*pi*r
for r=8.5/2------> r=4.25 in
[the length of a circumference]=2*pi*4.25---------->26.69 in

if 26.69 in  represent---------------> 1 revolution
720 in (bowling lane)------------> X
X=720/26.69------> X=26.98  revolution

the answer is
26 revolutions
