Log x+ log 7= log 42
log x=log 42 - log 7
log x=log 42/7 [ log a - log b= log (a/b) ]
log x= log 6
therefore:
x=6
Answer: x=6
Answer:
C

y=2x-1 your welcome I need to put more characters so skdjdnnn
Answer:
(-2,3)
Step-by-step explanation:
Step 1. Isolate x for 3x + 5y = 9
3x + 5y - 5y = 9 - 5y
3x = 9 - 5y
3x/3 = 9/3 - 5y/3
x= (9-5y)/3
Step 2. Simplify
-3*((9-5y)/3) + 3y = 15
-3*((9-5y)/3) = 9 - 5y = -(-5 + 9) + 3y
-9+5y+3y
-9+8y = 15
Step 3 Isolate y for -9+8y=15
-9+8y+9=15+9
8y=24
8y/8 = 24/8
y=3
Step 4 Substitute y = 3
x = (9-5*3)/3
-(6/3) = (-2)
x = -2
<h2>Answer- P=<u>18</u></h2>
Step-by-step explanation:
Greetings !
Firstly, find the class-midpoints (X) to solve for the mean.
Thus, mid points of each classes are

Solve, for <em>p</em><em> </em>using mean grouped data formula

multiply each values add them and solve for <em>p</em><em>.</em>
<em>
</em>
make a cross multiplication

subtract 270 from both sides

subtract <em>24</em><em>p</em><em> </em>from both sides
