she sold 12 cupcakes in total, 2 being coconut.
there would be a 2/12 chance that they would by a coconut cupcake. simplifying it would be 1/6
he could have 3 rows with 26 tomato plants in each. then for cucumbers he could have 4 rows with 14 plants each. he would need 7 rows to do this.
hope this ! brainliest appreciated!
the correct answer is that a rose bush costs $10 and a shrub costs $4
to solve this, start by writing equations for what each spent. use x for the cost of a rose bush and y for the cost of a shrub. below would be the equations for each.
rob: 8x + 5y = 100
amy: 8x + 8y = 112
now to find the cost, we multiply rob's equation by -1 and add them together. this will get x to cancel and allow us to solve for y.
-8x - 5y = -100
8x + 8y = 112
3y = 12
y = 4
so we know the cost of a shrub is $4. now we can plug that in to either of the original equations and solve for the rose bush cost.
8x + 5y = 100
8x + 5(4) = 100
8x + 20 = 100
8x = 80
x = 10
which means that a rose bush costs $10.
x = 9
