Answer: she need 315 more to buy the phone hope this helps
Step-by-step explanation:
Let x = the amount of grapes that can be bought for 0.40.
Note: By 90 I assume you mean 90 cents. The same for 40.
12/x = 0.90/0.40
0.90x = 12(0.40)
0.90x = 4.80
x = 4.80 ÷ 0.90
x = 5.33333
We can round the decimal to the ones place to get 5 grapes.
Answer:
D
Step-by-step explanation:
It’s d
From the secon equation, we can find x in terms of y by doing:
x = 2 + y
Pluggin this value of x in the first equation:
2(2 + y) - 2y = 14
4 = 14
We reached a false statement, which means that the given system of equations has no solutions. Another way to verify that would be by dividing the first equation by 2. Doing so, we would have equation 1: x - y = 7 and equation 2: x - y = 2, which is clearly impossible!
