Answer:
Z-7
6-7
-1
Step-by-step explanation:
we have to replace the value of Z and then subtract by seven.
-0.4x=2.5 divide both sides by -0.4
x=-6.25
Answer:
y=7+3x
Step-by-step explanation:
Since she already has 7 in her account and she ADDS 3 more each day you would multiply 3 by x which represents the number of days and add that to seven because she already had it. This would equal to Y which represents the total in her account
Ok sooooooooooo
Lets say your two fractions are
13/26 and 20/40
you can divide the bottom number by the top one and if you get the same answer for both then they are equivalent. For these you get 2 for both, which means they are equivalent.
another example would be if your fractions are
2/5 and 4/10
You can say well 2*2 equals 4 And 5*2 equals ten so these are equivalent fractions.
