Solve the equation
-7=y/7

y=-49

Step-by-step explanation:

y= −49

Step-by-step explanation:

Let's solve your equation step-by-step.

−7=

y

7

Step 1: Simplify both sides of the equation.

−7=

1

7

y

Step 2: Flip the equation.

1

7

y=−7

Step 3: Multiply both sides by 7.

7*(

1

7

y)=(7)*(−7)

y=−49

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
