The answer to this question would be x=a2y2
I think you do 120 divided by 5, but I could be wrong.
Answer:
Step-by-step explanation:
We first need to define a couple of variables. Let s = the cost of 1 squash and z = the cost of 1 zucchini.
Now lets translate the words into algebra:
"The cost of 5 squash and 2 zucchini is $1.32" ===> 5s + 2z = 1.32
"Three squash and 1 zucchini cost $0.75" ===> 3s + z = 0.75
There are several ways to solve systems of equations. Let's use substitution. We can find what z equals in terms of s by manipulating the second equation:
3s + z = 0.75
-3s -3s
------------ -------------
z = -3s +0.75
Now lets substitute (-3s + 0.75) into the first equation for z, then solve for s:
5s + 2(-3s + 0.75) = 1.32
Can you handle it from here?
(Hint: Once you have solved for s, you can substitute that value back into either of the equations and solve for z.)
Answer:
Michael is 38 and Sara is 29
Step-by-step explanation:
Because it says the sum of their age is 47 you do 47-9=38 so that would be Michael's age and than because Sara is 9 years younger than him and then you would do 38-9=29
Answer:
6 years
Step-by-step explanation:
Simple interest= P.R.T
I = $1300
P = 18000 deposit
Rate = 1.19%
T = ?
Putting into the formula we have
1300 = 18000x1.19/100xT
1300 = 18000x0.0119xT
1300 = 214.2T
Divide through to get T
T = 1300/214.2
= 6.069
So when we approximate T = 6 years
It would take 6 years to make $1300 in interest
